Figure 4-10 RS485/CAN Port pinout
To communicate via RS485 or CAN communication user will need a 6pin RJ11 connector. There are two
identical port for RS485/CAN as shown in Figure 4-10 and the pinout of RS485/CAN port 1 and RS485/CAN port
2 are the same. All signals with the same signal name of RS485/CAN port 1 and RS485/CAN port 2 are
internally connected. The two ports functions to provide user easy iHP rack to iHP rack daisy chaining of the
RS485 and CAN communication lines.
4.2.2.3.1 CANL and CANH
The CAN communication lines are for communicating via the CAN protocol.
4.2.2.3.2 RS485_A and RS485_B
The RS485 communication lines are used for communicating using the RS485 protocol.
