3.3 Rear Panel Description
The rear panel has AC input, output ground, RS485 and CANBUS mechanism.
RS485/CANBUS Connection
To communicate via RS485 or CAN, users need a 6-pin RJ11 connector. There are two same RS485/CAN
ports as shown in Figure 3-2, and the pin arrangement of RS485/CAN port 1 and RS485/CAN port 2 is the
same. All signals with the same name of RS485/CAN port 1 and RS485/CAN port 2 are Internal
connection. The functions of these two ports provide users with simple Hi-power rack to Hi-power rack
daisy chain RS485 and CAN communication lines.
