Troubleshooting the Controller
No LED's when the RLC-3 is powered up
C Check for +12 Volts at Power Connector
C Make sure that the +12 Volts is connected correctly. Center of Plug is (+), Shield is (-).
Only 1 LED is lit
C Check for bad or blown fuse
Only Some of the LED's are lit
C Short on that specific power supply. Call Link Communications Inc. if this occurs.
No Audio at Test Bus
C Check for main system power (All LED's lit)
C Is there a valid COR signal present on the receiver: (Default: Active Low)
Have audio at the test bus, but not on the transmitter
C Are the output audio pots adjusted correctly
C Is the transmitter connected to the controller's audio output: Pin 4 on the DB-09
C Is the PTT connected to the controller: Pin 3 (Low on Transmit)
The Voice Synthesizer seems muffled
C Turn down the pot marked 'Voice'
When I connect my COR, the RLC-3 will not accept it
C My COR is set for active Low, does the COR go to ground when active
C My COR is set for active High, does the COR go to ground when inactive
C Can the COR sink (2mA) when active
C Does the 5V pull-up resistor conflict with your radio
- Motorola R-100 Repeaters are susceptible to this
- Open collector the driver on R-100 repeaters
When I connect my serial terminal, I do not get any data
C Is your terminal's baud rate set to 9600,N,8,1
C Are all the RS-232 TX and RX and ground wires connected
C The controller requires all RS-232 signals (TX/RX/Ground) be connected
