Pin 1 = 8-32V DC
Pin 3 = Ground (A)
The network must have a 120 Ohm
terminating resistor at each end.
Please note that module power should NOT
be used to power any output devices.
The connection between CAN1 & CAN2 for
the power feed is not fused (protected from
short circuit current). During installation
the module power wiring on CAN1 & CAN2
pin 1 should have a 10-12A fuse before the
modules
