CAN bus

●

Disconnect the CAN bus from the CAN master (Node 1) and measure the line resistance out

(CAN_H to CAN_L):

Ω =

●

Reconnect CAN bus to CAN master, disconnect CAN bus IN from last Node (Node 4 on

Galaxy, Node 8 on Horizon / NeoHorizon) and measure line resistance back to Node 1

(CAN_H to CAN_L):

Ω =

●

With CAN bus connected measure line resistance (CAN_H to CAN_L):

Ω =

●

Measure the resistance from each CAN bus wire to machine chassis GND.

Ω = Ω =

●

Measure CAN bus line resistance:

– With CAN cable connected to Nextmove ES card = 60Ω (2 x 120Ω parallel)

– With CAN cable disconnected from Nextmove ES card or last node

●

Disconnect +24V from a Node and power on machine:

– What message is displayed?
