4.1.10 Open CAN Channel for Listen Only (L)

Summary

Opens the CAN channel in Listen Only mode. This is essentially the same as Open, although

attempts to use either Transmit command (T or t) will result in an error. Listen Only mode is

useful for monitoring the CAN channel without interaction from the CAN bus. CAN channel must

be initiated with selected speed (S or s) prior to use of Listen.

When in Listen mode, the channel must first be Closed (C) and then opened with Open (O) prior

to attempting to transmit frames.

NOTE: A minimum of three nodes are required on the CANbus network for Listen mode to

function.
