3.5 CAN TERMINATING RESISTOR SETTING
For CAN signaling to work correctly, the first and last devices on the CAN bus must have
terminating resistors of 120 ohms. The CAN-2 has a built-in terminating resistor that can
be enabled or disabled by a built-in jumper.
After removing the CAN-2 receiver from the housing, locate the terminating resistor
jumper (P2) on the PCB near the main connector in the lower right, as seen in Figure 07.

When the jumper is matched to the “TERM” position the terminating resistor is enabled.
When the jumper is in any other position it is disabled.
3.6 REINSTALLATION OF CAN-2 TO HOUSING
To reinstall slide the board and connector plate into the housing and press firmly to fully
seat the bottom connector plate onto the housing.
