2.6.1 PC Communications
There are four ways to communicate between a PC and
the generator set and/or transfer switch devices using
KBUS communication protocol. The PC connections
require optional software and possibly other hardware,
communication modules in the generator set controller
and/or transfer switch. See the monitor software
operation manual for details. Contact your authorized
distributor/dealer for availability.
Local Single Connection
A PC connects to the COM port of the controller module
using an RS-232 cable when the PC is within 15 m
(50 ft.) of the device or an RS-485 cable when the PC is
within 1220 m (4000 ft.) of the device. See Figure 2-10
or Figure 2-11.
