1. This device may not cause harmful interference, and
2. This device must accept any interference received, including interference that may cause undesired operation.”

INSTRUCTION TO THE USER

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.

• If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
  • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
  • Consult an experienced radio/TV technician for help.

Changes or modifications not expressly approved by Applied Wireless could void the user’s authority to operate the equipment.

Product Descriptions

• The SF900C Series switch followers are a two-way system designed to provide a quick and cost effective solution for a variety of wireless switching applications. Each unit has 4 or 8 inputs connected to a transmitter and 4 or 8 10 Amp SPDT relay outputs connected to a receiver. They are transceivers designed to work in pairs, the output relays at the far unit will “follow” the inputs at the near unit and vice versa.
• For the SF900C Pair, an optional loopback mode can be wired for each channel separately. At the RECEIVE end the relay output can be wired to activate the units corresponding input. This will close the corresponding relay at the originating TRANSMIT end confirming the switch change was carried out at the RECEIVE end.
• The inputs are opto-isolated and may be operated by an applied voltage that can be supplied by a power source from 5 to 24 Volts AC or DC through a switch contact, relay, sensor, PLC output, etc.
• These products utilize frequency hopping spread spectrum technology and are immune to interference and multipath fading. All inputs and outputs are independently isolated from each other and from the power supply and ground.
• Expected range with these products is 3 miles*. The receiver requires 12 to 24 Volts AC or DC (supply not included).
• Unobstructed, straight line-of-sight range, when used with the standard antennas included with the SF900C pair.

LED Indicators (Receiver)

• Power LED: Indicates that voltage is applied to the receiver.
• Learn LED : LED blinks when in the learn mode.
• Relay LED ’s : They indicate for each relay whether the relay is activated.

Data LED : LED indicates reception of RF signal at the receivers frequency of operation. For troubleshooting purposes, it can indicate the following:

1. Whether the transmitter is actually transmitting.
2. Whether there are interfering signals at the receiver’s frequency of operation. The LED should be dim if the transmitter has no input activated or button is not being pressed. Any LED indication would indicate that an interfering signal is present, the severity of which is indicated by how much the LED is activated.

Installation Instructions

• Before Beginning the Installation
• Plan your installation carefully. The physical location and orientation of the unit will have an influence on reception, particularly at longest ranges. For best results, the antennas should be positioned vertically (pointing either up or down). If necessary, use double-sided foam tape or hook & loop fasteners (not supplied) to secure the unit to a non-metallic vertical surface. Also, keep in mind that the RF signal from these spread spectrum products will travel through most non-metallic building materials (wood, stucco, brick, etc.), however maximum stated reception range is based on unobstructed line of sight conditions. Antenna extension cables are available when necessary to optimize antenna placement for range considerations.
• POWER HOOKUP
• The SF900C receiver has an internal DC/DC converter, so it may be connected to either 12-24 VDC or 12-24 VAC. The rightmost upper and lower terminals are for power. When using DC, the polarity is not important.
• The SF900C-OPT14 outdoor models are also available with optional 124/240VAC internal power supply.
• MULTIPLE RECEIVERS TO ONE TRANSMITTER HOOKUP
• If multiple receivers are used in a system, ACKNOWLEDGMENT must be disabled in all but one receiver. If this is not done, the transmitter will have multiple transmissions coming back at it at the same time, essentially jimmy it. This is an internal jumper setting that the installer can do, or the factory can do.
• Multiple transmitters to one or more receivers will not work.

LEARN PROCEDURE

• STANDARD TWO WAY APPLICATION : To pair two SF900C units, place both units in the learn mode by pushing their respective learn buttons. The learn lights will flash. Let’s call one the Base unit and the other the Remote unit. The second push of the learn button on the Remote unit will trigger the learning process. Once completed, the learn lights will turn Off. The Remote unit will have  learned and adopted the code and frequency of the Base unit. The Base unit is defined as the unit that has not adopted an alternate code. The distinction is important for the next example.
• More SF900C receivers can be added to the above system one at a time by using the same SF900C as the Base unit. However, the covers will have to be removed from the additional SF900C receivers and the ACK jumper will have to be moved to the NO ACK position to disable acknowledgements. When a signal is received from a transmitter, only one receiver, logically the Base unit, must reply with an acknowledgment to avoid collisions.

CHANGING THE FREQUENCY

• It is rarely necessary to change the frequency, however the following outlines the procedure should it be necessary:

• The least significant 5 bits of the address of the Base unit is used to determine the frequency of operation, one of 32 possible. Therefore, there is a 1 in 32 chance that any two units will be operating on the same frequency. The label on the units will have the 4-digit hex code as well as a 2-digit hex frequency. If two or more Base units are to be operating in the same area and they have the frequency, the Base units can be set to different frequencies.

• Use the 4-position dip switch covering switch positions 2 – 5 and an enable jumper in place of switch 6 allowing for 16 possible frequencies. To enable the alternate frequency selection, Jumper J4 must be moved to the two pins closest to the “EN” position
  and each of the dip switches must be moved up or down. To disable the alternate frequency selection, the enable jumper must be moved to the two pins farthest from the EN location and the dip switches must be moved to the center tri-state position. See the Frequency Select Switch Table. (1 is UP and 0 is DOWN.)

• NOTE: Whenever the frequency select switch, S1, is changed on the Base unit, the power has to be turned Off and back On again for the frequency change to take effect. Then, the Learn Procedure will have to be repeated for all of the Remote units associated with the Base unit that has a new frequency setting.

Remote Activation of Relay(s)
In this example, switch(s) activation on a water tank or other switch application, will remotely activate a relay(s) for activating, pump, motor, light or other device.

APPLICATION DIAGRAM

• Acknowledgement / Loopback
• In loopback mode, the target relay(s) is/are activated as in the earlier example. However, in Loopback mode, a transmission will then be sent back to the originating location and a relay(s) activated as feedback that the remote operation has been carried out.

TROUBLESHOOTING GUIDE

antenna should be vertical and placed in a location clear of obstructions and as high as possible.
 | RF Interference| Observe the DATA LED and try a different frequency if necessary.
Doesn’t Work| Battery| Always check the battery. With a weak battery it is possible for the SFT900C transmit LED to work without transmissions occurring.
 | Data Reception| Check that the DATA LED on the receiver is on bright when the transmitter is transmitting.
 | ID Code Match| Transients can sometimes cause a unit to unlearn a code. Redo the Learning process.
