Wiring Communications
The communication ports allow you to connect to a PC or laptop running FBxConnect software or
to other devices. Regardless of the interface standard [RS-232, RS-485 (4-wire), or RS-485 (2-
wire)], you must use FBxConnect to configure the port for proper usage.
Note: Older standards
refer to RS-485 (4-wire) as RS-422.
