Special Considerations
1) There can only be 1 assigned module to each slot. Identically assigned modules will be
handled in the order 1,2,3,4.
Example: I assigned 2 meter module to slot 1,4. I connected my 2 meter module to slot 4 and it
does not function properly. What is the problem...
The RLC-ICM searches for the correct module type beginning with 1 and cycling up to 4. The
first match the interface finds will get the information. The solution is to move your 2 meter
module from slot #4 to slot #1.
2) Non-connected modules will give a valid COR signal and hang your controller.
Example: I assigned my 440 module to slot #3 but moved it to slot #2 and re-assigned it there.
When I moved the module my transmitter on the controller stayed keyed all the time. What is
the problem...
The COR coming from the radio module is active high when unsquelched. Because you
previously had the 440 module on slot #3 and moved it, the COR signal from slot #3 just went
active. If slot #3 was turned on before you moved it, the COR signal is being processed as
though the module was still located on slot #3. The solution is to send the configuration
command C112*395* to tell the RLC-ICM to remove slot #3 receive and transmit from the
interface, thus causing slot #3 COR to go away. It is a good idea to tell the RLC-ICM to remove
non-connected slots from the interface to keep this problem from occurring.
3) I get a valid COR from a slot that is enabled, but I do not get any audio.
The slots audio is broken, thus a jumper is available to re-make the receive audio path. The
jumpers are labeled J11-J14. J11 is port 1, J12 is port 2, J13 is port 3, J14 is port 4. The
jumpers need to be in-line when there is no TS-64 present. When the TS-64 is installed the
jumper is removed. This allows the PL information to be filtered.
Another cause for this problem is the receive audio pot is turned down. Locate the module you
are having the problem with and to the right is a bank of variable resistors. The pots are
numbered according to the slot number. (Refer to the board layout for location) The pots
location arrow should be located at about the 3 o'clock position for best audio. The other pots
are for transmit level.
4) I don't seem to get any action when I program the RLC-ICM
First verify that your unit is wired correctly.
Second make sure your unit is powered.
Third make sure you have powered your 12v
Fourth make sure you get a response when programming
