2.6.1PC 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.

Local Area Network (LAN)

A PC connects to the device’s LAN. A LAN is a system that connects more than one device to a single PC. Acceptable devices include the Decision-Makerr 550 controller, Decision-Makerr 340 controller, M340 transfer switch control, M340+ transfer switch control, and PM340 power monitor. See Figure 2-12.

The 550 controller can be used as an RS-232 to RS-485 port converter in a LAN network if the 550 controller is located within 15 m (50 ft.) of the PC. This configuration is the Local LAN Conv option.
