WARNING! READ NOTES below before installing the
PV25.
Note
Use resistor between CAN_H and CAN_L line near PowerView
(included in some cables or factory purchased panels). Resistor
can be installed in the wire harness attached to Port A or a
terminating resistor (Murphy P/N 7800480) can be attached to Port
B. Do not connect a terminating resistor to Port A and B
simultaneously. If PV25 is not the last device on the CAN bus,
place terminator resistor at last CAN device.
Use SAE J1939 CAN compliant wiring.
Only use 120 OHM characteristic impedance cable, ex. Belden
9841.
CAN Shield connected to ECU end only.
Do not connect to PV25 Port B other than to terminate CAN bus.
See Note 1.
Terminating resistor at ECU end of harness.
WARNING:
Two 120 Ohm resistors should be located at opposite
ends of the J1939 CAN bus. Failure to comply will cause bus
failures. Only two 120 Ohm resistors are allowed on the J1939
CAN bus. ECU terminating resistor is typically located in the
harness, but can be located inside the ECUs. For ECU resistor
location check with OEM, equipment supplier, or ECU specification.
