CAN Bus Port Wiring
The Universal Serial Communication Cable can also be used for communication
with CAN bus devices. The cable’s Micro-D connector connects to the CAN bus
port on the OSA Remote. The 9-pin female D-Sub connector connects to CAN
bus field devices. The pin out for each connector is the same. The Micro-D
connector is shown in Figure B-11.
Important
Note that a shielded cable tied to the OSA Remote enclosure is required to
comply with product safety certifications.
The pin out information for the CAN bus port is shown in Table B-6.
