Identify an appropriate location to install the master clock.
The location should be accessible to the installer, and should be easily able to access its time base. This means that:

1. This master clock can receive NTP time from any NTP server over a Local Area Network (LAN) as a standard feature. If NTP is being used as the master clock time source, then the master clock must be installed in a place that allows it to connect to a network router/switch with CAT5 or CAT6 network cables.
2. The master clock may receive GPS time if it was ordered with an optional GPS receiver module. In this case the master clock will include a built in GPS receiver module, a GPS cable, and a GPS dome antenna. The GPS antenna must be installed on the facility’s roof. The master clock should be installed so that the GPS cable can reach between master clock and the GPS antenna.
3. If the application requires this master clock to receive time data from a third-party master clock, then this master clock should be installed close enough to the third-party clock that the user can run data wires between both clocks. Research your communication protocol and provide an appropriate wire gauge and length to connect both master clocks.
   If the master clock is being used to operate a wireless clock system, then there are additional requirements:
4. The master clock transmitter or Remote Antenna must be placed in a location where the signal is not interfered with or blocked. Be aware of large structures made of stone, concrete, bricks, or sheet metal as these materials will block a wireless signal. The installer should also be aware of other objects that may cause interference to the transmission including, but not limited to, large tanks of salt water, old microwave ovens, and large industrial machines.
5. The master clock transmitter or remote antenna must be within range of at least one wireless secondary clock or wireless repeater. If all of the secondary clocks are positioned beyond the range of the master clock’s transmitter, then the master clock must be connected to the local area network, and a network repeater must be installed. The maximum transmission distance of the master clock transmitter in an unobstructed, open space is 3300 feet (1000 meters). Obstructions will reduce this distance, particularly obstructions made of the materials mentioned in the previous paragraph.

A mounting base and pole must be purchased in order to attach the antenna to a roof. A dedicated base and pole may be ordered from the master clock supplier by requesting part number M-GPS-MTG-KIT-1. If the installer wishes to purchase their own parts, the pole should be capable of attaching securely to the base and the antenna, which requires either a 1″ outer diameter pipe with 14 threads per inch, or a 3/4″ NPT pipe. The pole and base must also each have a hollow space large enough to allow the GPS cable to pass through both and attach to the antenna.

M-GPS-MTG-KIT-1 (Optional Accessory)

If the mounting base and pole are made of metal, then the user must also provide a grounding cable for the pole. The grounding cable should be 8AWG (8.4mm²) or thicker.

If an optional surge protector is included with the master clock, then the user must provide a second grounding cable. This cable must also be 8AWG or thicker. Failure to install this grounding cable will prevent the surge protector from functioning correctly.

Master clocks with the optional GPS Receiver module installed will include a GPS antenna and GPS cable. The standard cable provided is 75ft (22.9m). A dedicated, longer cable can be ordered through the master clock supplier by requesting the following part numbers:

E-ANT-CBL-150F-1 150ft (45.7m) E-ANT-CBL-300F-1 300ft (91.4m)

Please note that your dealer can also provide solutions for projects where a GPS cable longer than 300 feet (91.4 meters) is required. For more information, please contact your dealer. Using a GPS cable other than the one provided by your dealer might result in an unreliable time signal. For this reason, using a different GPS cable than the one provided is strongly discouraged and will void the master clock warranty and support.

Installing a Master Clock – GPS Antenna (Optional)

Connecting the GPS cable to the master clock is easy: screw that end of the cable into the dedicated port on your master clock.

GPS Cable Connector

Continue by connecting the GPS Antenna to a roof. When installing the GPS antenna, pick a location where the antenna has a clear line-of-sight to as much of the sky as possible, such as on top of the roof. Avoid locations that are blocked by trees, tall buildings, metal exhaust vents, large rock formations, and canyon walls. Do not mount the device inside, on, or immediately outside of a window, as these locations do not promote reliable signal acquisition.

1. Thread the GPS cable through the mounting bracket and pole.

GPS Antenna

2. Screw the end of the GPS cable to the connector on the GPS antenna. The assembly should now look like the picture on the right.

GPS Cable leading to Master Clock

3. Insert one end of the pole into the mounting bracket. While holding the base stationary, twist the pole counter clockwise until it is firmly screwed into the base.
4. Insert the other end of the pole into the bottom of the antenna. While holding the pole stationary, twist the antenna counter clockwise until it is firmly screwed onto the pole.

GPS Mounting Pole M-GPS-MTG-KIT-1 (Optional Accessory)

5. If you are using a metal pole, attach a grounding wire to the pole.
6. Attach the completed assembly to the roof.

GPS Mounting Bracket

7. Within 30 minutes, the antenna should acquire a GPS signal.

If your master clock is set to receive GPS time data as its primary time input, a loss of GPS time data will cause a red blinking circle to appear above and to the left of the third digit on the LED time display. The circle will blink on and off until the signal is regained, or until a different primary input is set (such as an NTP server). After completing the installation, make sure that this LED is not blinking.

When used as a backup clock, this master clock accepts RS485 Data from another clock of the same model and passes them through its clock-sync relay switches. If data is not received for a period of time from the Primary Master Clock, the relay switches shift to sending RS485 data from its own data ports.
In this configuration, the backup master clock may only be used as a backup for RS485 and 2-Wire Digital Clock systems.
The backup feature must be enabled in the Web Interface for the clock to function in this manner. Refer to the section “Web Interface Synchronization” for activation instructions.
In an RS485 System, Output A attaches to Blue, while Output B attaches to Red.
In a 2-Wire Digital System, Output A attaches to Converter Box Input A, while Output B attaches to Converter Box Input B.

This master clock model may be equipped with the optional 4 or 8 programmable relays (switches). These allow the master clock to trigger third-party systems and/or devices via a dry contact closure or opening. The master clock does not provide the power to the third-party systems or devices, but simply triggers them to go ON or OFF at pre-determined times per user set schedules. Programming the schedules can be done by using the master clock built-in web interface or by using its front keypad. This page includes the line drawing which shows examples of the wiring of the third-party device. Instructions for setting the programmable relays so they will trigger at user preferred times is explained in a different section of this manual.
Each programable relay (zone) has one “Type C” contact with one normally open (NO), one normally closed (NC), and one relay common (COM). While the relays are off (not being activated by the master clock), the common port will be connected to the normally-closed port, creating a short between them. When the relays are on (being activated by the master clock), the common port will be connected to the normally-open port.
One of the most common uses for the relays is to control a school bell system. Usually, bells are connected to the common and normally open relay outputs. While the relay is off, the bells wiring will remain disconnected from power, and the bells will remain off. When the master clock activates the relay following the programmed events, it will connect the common to the normally- open output, closing the circuit and supplying the power to the bells.

Each programmable relay max load is up to 8 AMPS at 120VAC or 5 AMPS at 240VAC
If the current load is, or close to 5 AMPS (240VAC) or 8 AMPS (120VAC), it is better to distribute current consumption between more than one relay
If the load is greater than 5 AMPS (240VAC) or 8 AMPS (120VAC), use 2 or more relays or as needed

Basic Configuration – DHCP and Static IP

NOTE: Firewall Ports 80 (TCP) and 123 (NTP) must be open to use the master clock on a network.

The function of this section is to get a new master clock up and running as quickly as possible. This section is mandatory for clock systems that will use a Local Area Network as a distribution system, or NTP/SNTP data as a time source. If your clock system does not require use of your local area network and you do not wish to use the web interface, you may skip this section and continue with the section labeled “Manual Controls”.

The master clock is set to DHCP by default. This setting allows the network to automatically assign an IP address to the master clock. It is important to note that this address may change if the network connection is reset.

If the facility where the clock(s) will be installed into has a DHCP server, please follow these steps:

1. Connect and power the master clock to the network via a network cable. (Note: in order to have it powered, network cable must be receiving power through a PoE Switch or PoE Injector)

2. Once powered, press the two buttons on the front of the master clock and write down the IP address that displays. (or, double click on the master clock when using the Network Clock Monitoring Software)

3. Go onto a web browser that is connected to the same LAN (Local Area Network) as the clock and type the IP address of the clock into the address bar.

4. This should bring you to the web interface of the clock and you will be prompted to log in. The default password is 6063.

5. Once logged in, select “Network Settings” on the top of the page. Refer to image A shown below.

6. In “Network Settings” note the DHCP option. Toggle DHCP from “ON” to “OFF”. This will make the current IP address of the clock static. Refer to image A shown below.

7. Enter the Gateway IP Address, Subnet Mask, DNS Router, and Static IP Address as provided by your network administrator.

8. After DHCP is switched to off, power cycle the clock by unplugging the network cable from the clock’s RJ-45 receptacle, waiting 10 seconds, and then plugging it back in. Press the two buttons on the front display of the clock and, if all was done correctly, the clock will display its new Static IP Address.

Basic Configuration – DHCP and Static IP

If you wish to set up the master clock with a crossover cable, then the following series of steps must be followed. You should check with your network administrator and confirm that the computer connecting the master clock has an IP address other than 192.168.0.123, a subnet mask of 255.255.255.0, and a gateway address of 192.168.0.1. The IP address may be discovered by performing step six below. It is important to note that this address may change if the network connection is reset.

1. Power the master clock.
2. On the master clock keypad, press and release button 1 four times.
3. On the master clock keypad, press and release buttons 3 and 6 at the same time.
4. On the master clock LCD screen the message “SURE ENTER CROSSOVER” should appear. Press the YES/ENTER button.
5. Unplug the master clock, wait fifteen seconds, and power the master clock again.
6. Confirm the new master clock IP address by pressing and releasing the 1 and 9 buttons on the master clock front panel simultaneously. This will cause the IP address to appear on the LCD screen. The LCD screen will automatically switch back to displaying the time after four seconds have passed.
   The master clock Web Interface should now be accessible through the IP address 192.168.0.123.
   To configure the Web Interface, continue to the section labeled “Basic Configuration–Web Interface”

6. The following configurations are done in the System Settings tab in the master clock:
   6A) When installing a 2-Wire Clock System the master clock is set to send RS485 time data to the converter box once every second as standard. This time data rate sent from the master clock to the converter box can be changed (if needed) by clicking on System Settings and changing the “Send RS485” to another value.
   6B) When installing an RS485 Clock System the master clock is set to send RS485 time data directly to the secondary clocks in the system once every second as standard. This time data rate sent from the master clock to the secondary clocks can be changed (if needed) by clicking on System Settings and changing the “Send RS485” to another value.
   6C) When installing a Wireless Repeater for a Wireless System, the wireless repeater (Not a Network Repeater) can simply receive the time via a wireless signal transmitted from a master clock (that is equipped with a transmitter or from a wireless secondary clock). Simply plug the wireless repeater to local power (110VAC or 230VAC) and it will repeat the time signal as often as it receives it. A Wireless Repeater can also obtain time data directly from a master clock through a pair of electrical wires that send the RS485 time data. The master clock is set to send RS485 time data directly to the wireless repeater once every second as standard. This time data rate sent from the master clock to the wireless repeater can be changed (if needed) by clicking on System Settings and changing the “Send RS485” to another value.
   6D) GMT Time Offset – The master clock is set to receive GMT (Greenwich Mean Time) also known as UTC (Coordinated Universal Time) from an NTP Server (standard) or from a GPS (optional). In order to have the master clock send the correct local time to the secondary clocks in the system (at the geographical location of where the clock system is installed), the GMT offset for your time zone must be set. In order to do that you will need to know the correct GMT offset for your location, for example: New York is -5 (hours offset from GMT), London is 0 (Hours) and Tokyo is +10 (Hours). This is done in the System Settings tab of the master clock web interface in the “GMT Offset” field.
   6E) In some scenarios, there may be a need to adjust the time displayed by the master clock. If your application requires such an offset, enter a value (in seconds) into the `Bias seconds’ field of the needed offset. Keep in mind that an offset that is greater than 3600 seconds (1 hour) can be more easily set by adjusting the GMT offset field.
   Please refer to specific product manuals for more information.

Manual Controls – User Level

The purpose of this section is to get a new master clock up and running using the manual controls on the front of the master clock. If you would prefer to program the master clock through the convenience of the web interface, go to the section labeled “Basic Configuration–Web Interface” for an alternate programming method. This section continues from “Basic Configuration–DHCP and Static IP.” Please complete that section first before proceeding with the items below.
This master clock should be set to receive accurate time through an NTP server as a standard feature, or from a GPS receiver as an optional feature. The master clock can also act as a stand-alone master clock, meaning that it will not receive accurate time and update its time data on a regular basis. Although we always recommend that the Master Clock receive time data from an accurate time source, if there is a need for the master clock to act as a standalone device, the Master Clock’s internal real-time clock can be set manually.

1. Identify an appropriate location to install the master clock or remote antenna. See the pictures on the next page for examples.
· The master clock transmitter or Remote Antenna must be placed in a location where the signal will not be blocked or inhibited. Be aware of large structures made of stone, concrete, bricks, or sheet metal (including metal network cabinets) as these materials will block a wireless signal. The installer should also be aware of other objects that may cause interference to the transmission including, but not limited to, large tanks of salt water, old microwave ovens, and large industrial machines.
· The master clock transmitter or remote antenna must be within range of at least one wireless secondary clock or wireless repeater. If all of the secondary clocks are positioned beyond the range of the master clock’s transmitter, then the master clock must be connected to the local area network, and a network repeater must be installed. The maximum transmission distance of the master clock transmitter in an unobstructed, open space is 3300 feet (1000 meters). Obstructions will reduce this distance, particularly obstructions made of the materials mentioned in the previous paragraph.
2. Install the master clock and confirm that it is properly configured and powered on. DO NOT INSTALL SECONDARY CLOCKS UNTIL THE MASTER CLOCK IS CONFIGURED AND POWERED.
3. Confirm that the antenna has been correctly installed. For surface-mount master clocks, the antenna should be installed in the socket on top of the master clock. For rack-mount master clocks, the remote antenna should be plugged into the socket on the back of the master clock. Refer to the Remote Antenna installation instructions, step 7, for details and a diagram.
4. Power all secondary battery-powered clocks within the same room as the master clock. Wait until the clock receives time data from the master clock before taking it to its point of installation. Refer to the secondary clock manual for detailed steps.
Please be aware:
A master clock equipped with a wireless transmitter will automatically begin to transmit time data every minute, beginning at the top of the minute.
If a repeater is being directly powered by the facility’s electrical systems, then the repeater will receive time data and correct within the first 60 seconds, or immediately upon being powered on.
If a wireless secondary clock is being directly powered by the facility’s electrical systems, then the secondary clock will receive time data and correct within the first 60 seconds, or immediately upon being powered on.
If a wireless secondary clock is being powered by batteries, then the clock will receive time data and correct within the first 2 hours (in normal mode) or 4 hours (in economy mode), or immediately upon being powered on.
If a wireless secondary clock or repeater is not receiving power from the facility’s electrical systems or batteries, then the clock or repeater will not function at all. Wireless clocks and repeaters ARE NOT POWERED WIRELESSLY, they only receive time data wirelessly.
If a wireless secondary clock or repeater is powered, but the master clock is not powered, then the wireless secondary clock or repeater will not receive time data.

Only available if countdown option ordered with clock

Marks the end of an Event Countdown*

Only available if countdown option ordered with clock

*In an EVENT COUNTDOWN, the master clock automatically computes the amount of time between an event where CStart is selected and the next event where CStop is selected. The master clock then sends a command to digital clocks that commands them to perform a countdown that begins at the event time of the CStart, and ends at the event time of the CStop.
Event Countdowns must have both a CStart and CStop to activate. The CStart and CStop events must also occur during the same day; a CStart that occurs Thursday Night will not recognize a CStop that occurs Friday morning. Event Countdowns cannot exceed 18 hours in length.
This countdown command does not apply to all models of digital clocks. Digital clocks that receive the time through a sync-wire protocol, or that obtain the time through your facility’s computer network, will not receive the countdown command. To perform a countdown on IP and Wi-Fi clocks, use the Network Monitor software.

1. Retry Failed Server After – Under normal circumstances, if the master clock cannot get NTP time from the selected server on the list, it will attempt to get NTP time through another one of the listed addresses. This field allows the user to decide how many NTP data updates should pass before the master clock retries a failed server address.
2. NTP Server Addresses – These fields allow the user to create a list of servers to be used as sources for NTP time. Each used field should have a URL or IP address for a functioning NTP server. At least one field must be filled for the master clock to acquire NTP time. The master clock already comes pre- programmed with ten third-party NTP server IP addresses that will allow the master clock to ping them on a regular basis through a network with access to the Internet. A user may change an IP address of an NTP server. If a user has an in-house NTP server, or wishes to use an NTP server other than the ten listed ones, they may select one of the IP addresses, delete it, then enter the IP address of an NTP Server of the user’s choice. A user may select which address the master clock should contact first by clicking on the white circle to the left of the desired field. Addresses that fail to return NTP data when queried are highlighted in red.
3. Rotate Servers – When the box is selected, the master clock will attempt to acquire NTP times by rotating between the entered server addresses with each update. In other words, if Server addresses 1-5 have been entered, and the Rotate servers box has been selected, then the master clock will acquire time from the first server address on the first update, the second server on the second update, and so on. Empty fields are not treated as functioning addresses and are skipped. When using an in-house NTP server as a time source, the Rotate Servers box should NOT be selected (empty).

The Master Clock NTP Server Feature allows this master clock to provide NTP or SNTP time to DVRs, Voice-over-IP telephones, IP-operated cameras, or any IP device that can receive NTP or SNTP time protocol over a LAN.
Sapling NTP 7000 and NTP 8000 Master Clock models include the NTP server as a standard feature. Sapling also offers the NTP server as an optional upgrade to SMA 2000, SMA 3000, SMA 5000, and SMA 6000 Master Clocks. This upgrade is only available when selecting features for the master clock before purchase.
When using this master clock as an NTP server, the Master Clock MUST BE SET TO A STATIC IP ADDRESS. A master clock that has been set to DCHP will occasionally refresh its IP address, making it impossible for other devices to consistently receive NTP time data. Refer to the sections of this manual labeled “Basic Configuration – DHCP and Static IP” and “Web Interface – IP Settings” for more information.
IP devices may receive NTP/SNTP time from SMA Master Clocks with the NTP Server Upgrade through the following procedure:

1. Locate the master clock IP address. There are three methods for doing this:
   a) On the Web Interface, look under the IP Status tab for the field “IP” address.
   b) For SMA 2000, SMA 5000, and NTP 7000 clocks, press and release both buttons on the front panel simultaneously twice for the first three digits of the IP address. Pressing both buttons again simultaneously will show the next three digits. Repeat for the last two sets of numbers.
   c) For SMA 3000, 6000, and NTP 8000 clocks, press keys 9 and 1 simultaneously. The IP address will appear at the bottom of the master clock LCD screen.
2. Enter the master clock IP address as the NTP source for the NTP compatible device. Consult the IP device’s manual for information on where to enter the IP address.
3. Confirm that the IP device is receiving NTP data from the master clock by comparing the time on the master clock LED display to the time on the device. Consult the IP device’s manual for information on how to view the time on the device.

Support – Frequently Asked Questions and Troubleshooting

The master clock is not powering up. What do I do?
Check the connection between the master clock and power source. The power cable should be correctly plugged into the power source and master clock. The power cable should also be correctly wired into the green connector. The connector should also be fully inserted into the port on the master clock (you will hear a clicking noise if it has been inserted correctly). The master clock does not have an on/off switch; it will begin to function the moment it is properly connected to an active power source.
How can I determine that my master clock is showing the correct time?
The easiest way is to compare the time on the master clock to www.time.gov. If the time on your master clock is accurate, it should be within one second of the time demonstrated by the time.gov HTML5 application for your time zone.
Please note that the accuracy of a time source is dependent on its connection with a Stratum 1 NTP server or equivalent hardware. While many NTP servers either are Stratum 1 NTP servers or directly communicate with Stratum 1 NTP servers (or equivalent hardware, such as GPS satellites), it is possible to acquire time from an NTP server that is not properly synchronized to UTC. It is the responsibility of the master clock installer or network administrator to research the reliability of an NTP server before using it as the primary time source for the master clock.
May I use any NTP/SNTP server for downloading time data?
Any NTP or SNTP server that publicly distributes NTP data may be used.
How do I get a longer cable for my GPS antenna?
If a longer GPS cable is needed for the project, a pre-approved cable must be ordered directly from the master clock manufacturer, or through an authorized dealer. These pre-approved cables have been checked for system compatibility, proper functionality, and time signal quality. Using a GPS cable that has not been pre-approved by the manufacturer will void your warranty and may not correctly relay data to the master clock.
The part numbers for longer cables are listed below:
150 feet / 45.7 meters — E-ANT-CBL150F-1
300 feet / 91.4 meters — E-ANT-CBL300F-1
If your project requires a cable longer than 300ft/91.4m, please contact your authorized local dealer for more information.
What do I do if the master clock isn’t receiving a GPS signal?
First, make sure that the connection between the antenna and master clock is securely tightened at both ends of the cable. Next, confirm that the antenna is situated in a location where it has access to the greatest amount of unobstructed sky. The top of a roof, away from chimneys or air conditioning equipment is usually the best possible location. Pointing the antenna out of a window is not sufficient enough to acquire a signal.

Support – Frequently Asked Questions and Troubleshooting

Does this master clock convert time data to 2-wire 24-volt communication protocol?
No. To convert time data to the 2-wire 24-volt communication protocol, the user must purchase a converter box by ordering part number SCB-100-000-1
My sync-wire secondary clocks do not seem to be getting the time shown on the master clock. What went wrong?
Keep in mind that the clock 1 and clock 2 outputs control the sync-wire systems. Some Sync-Wire systems may take up to 12 hours to fully synchronize. Check to be sure that the correct system has been set for the appropriate clock circuit. Check the setting definitions under the section labeled Manual Controls: Setting 20.
What communication protocols (inputs) can this master clock use to receive time data?
NTP, SNTP, 59 minute correction, four different versions of 58 minute correction, National Time/Rauland, Dukane Digital, Rauland Digital, Once a Day Pulse, and an RS485 protocol.
If the master clock has a wireless transmitter, then it can accept signals from any other device by the same manufacturer that transmits a wireless time signal.
If a GPS module and antenna was ordered with the master clock, it can receive time from GPS satellites.
How often does a master clock wireless transmitter broadcast a synchronization signal?
The master clock transmitter is set to broadcast a synchronization signal once every minute, at the top of the minute.
What do I do if I cannot connect to the master clock web interface?
First, make sure that you are using the master clock’s current IP address. To view the master clock IP address, press and release both the 1 and 9 buttons on the front panel simultaneously. This will cause the the IP address to appear on the LCD display.
If the IP address is correct, contact your network administrator and ask them to confirm that there are no provisions in your network firewall that prevent you from accessing the master clock. Firewall Ports 80, 123, and 1777 must be open to use the master clock on a network.
If all else fails, connect to the master clock with a cross-over cable.
What web browser should be used for accessing the Web Interface?
The Web interface has been found to function on Internet Explorer, Mozilla Firefox, Safari, Opera, and Chrome. It is accessible on desktop and mobile computers, as long as the device is on the same network as the master clock.
Can I connect to the web interface through a cross-over cable?
Yes. This master clock can be accessed by connecting a cross-over cable directly between the network ports on the clock and a computer.

Support – Frequently Asked Questions and Troubleshooting

Why isn’t the Master Clock appearing on the Network Monitor Software?
Check the following:

1. Confirm that the computer running the Network Monitor Software and the Master Clock are on the same subnet.
2. Confirm that Port 1777 (UDP) is not being blocked by the computer running the Network Monitor Software or by any of the network components (switches and routers) between the computer running the software and the Master Clock.
   Why didn’t my master clock self-adjust for Daylight Saving Time?
   Check the following:
3. Is the master clock showing the correct date? If the master clock is not showing the correct date, then it does not know that it is time to make the Daylight Saving Time adjustment.
4. Is the master clock connected and synchronized with an accurate time source such as a Reliable NTP server or GPS? If the master clock is not properly synchronized, then it may not have received proper time data.
5. Was a Daylight Saving Time configuration properly set through the web interface? If the master clock is not configured to make an adjustment for daylight saving time, then it will not adjust.
   Does this master clock replace all previous master clocks made by this manufacturer?
   This series of master clocks are designed to replace SMC, GPS, STR, and SSM series master clocks, but requires that the user select the appropriate upgrades (such as GPS) at the time of purchase.
