1. Turn the Johnson panel power switch off.

2. Determine the type of signal received by 

the field termination board. Consult the 
Johnson Controls manuals if necessary. 
The InterOP8500 must be configured to 
receive the same type of input as the 
previously removed Johnson boards.

3. Set the InterOp8500 jumpers as follows:

• For RTD mode insert a jumper for the 

individual input. The jumpers are 
located along the lower right side of the 
InterOP8500 board (see Figure 13).

NOTE

NOTE

NOTE

NOTE If using a solid-state current 
switch on a digital input, the resistance 
must drop low enough for the module to 
recognize it.

• For voltage and potentiometer mode, 

remove the jumpers. (Current mode can 
be configured by adding an external 

sense resistor. For 4-20mA use a 250 
ohm resistor Figure 14). Turn the 
InterOP8500's power switch on.
