Refer also to the external device’s or system’s instruction manual.
General Procedure
1. Remove the CAN termination plug from the bottom CAN connector on the System Interface circuit card of the last bay (see
Figure 21 for location). Connect the device or system to the bottom CAN connector on the System Interface circuit card of the
last bay. Refer to Table 7 for pin-outs. Refer also to the external device’s or system’s instruction manual.
Optional SM-Temp Module Procedure
