Figure 1 – Wiring Diagram

Compatibility:
All Matko XT Series transceivers and receivers are compatible with each other. An XT300 Transceiver can talk to an XT100 Receiver; however, the units must have been configured to the same ID (XT100 only works on ID 0)
Power:
The XT Series transceivers can operate with any voltage source from 7.5 VDC to 12 VDC. This includes running power directly off of an SBL Series remote VCC and GND.
Install Notes:
-Mount all units in a direct line of sight with each other with all antennas on the same plane (all pointed straight up or straight down).

Configuration
All units must be on the same ID to communicate with each other. XT100 units are fixed on ID 0. XT200 units are selectable between ID 0 and 1. XT300/400 units have IDs 0 through 15 available.

1. Set the ID DIP switch to the desired ID
2. Set the baud rate DIP switch to match the serial device connected to the XT unit. XT100 units are fixed at 9600 baud RS232.
3.  Press the CONFIG button on the transceiver to save the DIP switch settings. The three green configuration LEDs will illuminate as setup progresses. When all three LEDs light up Configuration is complete. *
   • If there is a problem with configuration the red CONFIG LED will blink every 5 seconds up to 6 times as internal communication is re-established. The red CONFIG LED will then blink several times rapidly. Wait a minimum of 5 seconds before pressing CONFIG again.

• It may take up to 30 seconds after configuration before a link is established with other units and data is transmitted between units.
  When the transceiver has been properly configured and properly wired according to figure 1 the corresponding green LED (RS232, CLOOP, or RS422) will blink with each data transmission. This LED will blink regardless of whether the receiver side has been properly configured or even powered on. The red RX LED will blink on the receiver side with each data burst received from the matching transceiver. Ideally with each green blink on the transceiver side there will be a corresponding red blink on the receiver side. If the receiver side is infrequent the signal is not reliably getting from one unit to the other.
  Reposition antennas for direct line of sight as much as is feasible.

XT400 IO (Input Output) Setup
The XT400 transceiver has the ability to pass up to 4 input lines to one or more XT400 Transceivers set for outputs. You may not have more than one unit set for input on the same system as the two units would conflict with each other. Each transceiver can either be an input device or an output. You cannot mix input and output on the same device.
In addition to setting the DIP switches as mentioned above the unit will also need to have the removable jumper placed in the correct spot as well as two 8 pin chips.
-For input lines, place the jumper on input and make sure the two MCT6 chips are inserted into the sockets to the right, labeled “IN”
-For output lines, place the jumper on output and make sure the two MCT6 chips are inserted into the sockets to the left, labeled “OUT”
*Input and output are only in reference to the digital lines. Serial data is bidirectional regardless of jumper settings.

Example Installations

Case 1
Typical Setup: Indicator to remote using two XT300 Transceivers

Case 2
Networked Indicators

Case 3
An Indicator to two remote displays with built in receivers

Case 4
Indicator with a closed contact switch to a SBL-4SG-XT400

Case 5
Indicator with a remote zero/print switch near the Display

Case 6
A switch remotely controlling an AC Relay for a traffic light

*You can reverse the logic by connecting the coils of the AC relay to IO 0 and +5 VDC instead of ground

Repeater
If the transceivers/receivers are working but you cannot get the needed range for the job site you can try to add an extra transceiver to system as a repeater unit. Mount the unit roughly in the middle of the distance with line of site to both ends. You will need power at this location. Add a jumper wire from 232 RXD to 232 TXD. Any signal that can make it to this transceiver will then be transmitted back out. The original transmitting unit will have the data echoed back to it, so this will not work for bidirectional communication.

Troubleshooting

Before you call, please see if any of the below problems/solutions match your conditions.
The Red PWR LED doesn’t come on
Verify the power supply is turned on and putting out 7.5 to 12 volts DC and that the wires are securely screwed into the terminals.
No LEDs are blinking on the unit connected to the indicator
Make sure the indicator’s port is enabled for continuous output and that the unit is wired according to the wiring diagram. The indicator’s transmit should be wired into the XT units receive terminals. The corresponding LEDs should blink with every signal regardless of the DIP settings or even if the signal is good or not.
No LEDs are blinking on the unit connected to the remote display Make sure there is an LED blinking on the side connected to the indicator first. If that side does not blink the receiving side will not blink. If the indicator side is blinking, then make sure both units are set to the same ID and reconfigure both sides by pressing the CONFIG button on each side. Try unplugging one unit and plugging it back in to have the wireless units re-establish the network. If the remote display end still does not blink, then the problem may be distance/obstacle related. Try bringing both sides into an office and see if they communicate over a short distance. If they do, then reposition the units for better line of site or add a repeater to the system.
The RX LED blinks on the remote display side of my XT transceiver, but the remote shows “NoData” The problem is probably with the wiring. Make sure you are coming out a transmit on the XT unit and going into a receive on the remote display. Try changing to a different transmit port if you have any unit other than the XT100T.
All other models have RS232, current loop and RS422 as options. You do not have to use the same loop on the remote display side as you use on the indicator side.
The RX LED is blinking on the remote display side, but the remote is blank or shows random numbers.
Verify the baud rate is correct and press the configure button on both ends. Reset the remote display to factory defaults by holding the LEFT and RIGHT buttons during countdown. After the unit starts to count down for the second time let go and the remote should display the correct baud rate. If still blank, try shift data over to the left or
right.
The system is reliable except when weight is on the scale
Make sure that when a truck pulls on a scale it does not come between the two antennas. A truck acts as a solid metal wall blocking the signal
The system sometimes works and sometimes does not.
Make sure nothing has changed at the site such as trees growing into the line of sight or gravel piles growing to block the signal. If you are at the far edge of the maximum usable range then many things can degrade the signal including, temperature, humidity, to large equipment being run nearby. In general, make sure both antennas are pointing straight up and down, are as high above the earth as is reasonably possible and have a clear line of sight to each other. Other than that you may need a repeater added to the system to extend the range *If you are still unable to get the unit working after going through this list, please call our tech support at 844-CAL-BTEK (844-225-2835)

RF Exposure
WARNING: To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-located in conjunction with any other antenna or transmitter. The preceding statement must be included as a CAUTION statement in OEM product manuals in order to alert users of FCC RF Exposure compliance.
