Troubleshooting
Testing Range and RF communications
Press and release the ÄTestÅ button on one of the units and observe the six Signal Strength LEDs. If any of the
blue LED 1 through LED 6 lights up momentarily then the transmission between the two units was successful.
This establishes that the radio communications between the two units is operational and even with only the
LED 1, there is adequate signal strength for proper function.
For the best performance between the Controller and Remote units
1. Power both units with their own dedicated power supply with a minimum of 1A @ 12VDC.
2. Route all cables and wiring away from the area near the Antenna.
3. Avoid routing cables and wiring over the top of the unit.
4. Mount both units oriented with the antenna at the top of the unit facing upwards.
5. Rotating either (or both) of the units may provide an improvement in range.
6. If additional range is required, avoid placing either unit on or near metal and place each unit at a
higher location.
Manually Testing Relays
Each Relay pair can be manually tested to verify operation. Using a jumper wire, short the Relay input, such as
R1 IN to GND, then monitor the Relay 1 OUTPUT on the bridge pair unit. This can be done on all four Relay
inputs: R1 IN, R2 IN, R3 IN, and R4 IN. Remember, if testing the relays on the Remote Interface REV2 (DS004-
REMOTE REV2), that the relays are solid state type and a ÄclickÅ will not be heard when these two relays
activate and so a meter or device would need to be connected to verify relay activation.
