RS-485/422 Cable Wiring

You can wire DFlex-4/104 adapters with the RS-485/422 option
in various ways to communicate with RS-485/422 peripherals.
This section will descibe a few examples of RS-485/422 cabling
schemes.

Figure 15

describes a 4 wire cabling scheme between a port on

the DFlex-4/104 adapter to a port on the RS-485/422 peripheral.
