Multiple Power Supply Connections to RS-485 Bus
Up to 30 units may be connected to the RS-485 bus. The first unit (master

units (slave units) are connected with the RS-485 bus via the J6

multichannel addresses.
A standard straight-through RJ-45 ethernet network cable can be used to
provide the connection between the power supplies. See Figure 5-14.
