RI-1 CIRCUIT BOARD ASSEMBLY
RI-1 CONFIGURATION JUMPERS
JP4 – TX Modulation Select:
If you are interfacing directly to a true FM type modulator, you will want to disable the controller’s transmitter emphasis stage.
This is accomplished with a jumper (JP-4) on the circuit board. See the figure to the right. Pin 3 is located in the lower corner
of the board. For modulators that are true FM and without emphasis, place jumper on pins 2 and 3. For all other types of
modulators and audio interfaces, including VoIP, you will want to place the jumper on pins 1 and 2.
JP1 – Auxiliary Buss Select:
If you are working with the PE-1 or you do not have the RI-1 controller
connected to another controller, you can skip this sub section.
The RI-1 does not support a full cross point switch on the auxiliary buss.
This means that if you are going to connect the RI-1 to another RI-1 or
RI-300, you will use jumper blocks need to select the input and output
channels on the auxiliary buss. Use the diagram to the right to assist on
jumper placement of each channel.
When deciding on setting jumpers, you must first decide on what
channels you will be using. If you will be connecting an RI-300 to the
RI-1, the RI-300 is default to output on channel 1 and the RI-1 is default
on channel 8. You would then install a jumper on pins 1 and 2 so that the
RI-1 can listen to the RI-300. You then place a jumper on pins 15 and 16
so that the RI-300 can listen to the RI-1.
All jumpers are placed in combination of one for AUX-IN and one for
AUX-OUT. You should never place multiple jumpers for the AUX-IN or
AUX-OUT.
After you have placed the jumpers, you then use System Commands 34
and 35 to enable and disable the input and output. You can also use the
programming software (PS-3) to adjust these default values. Click
System and Auxiliary Setup.
