Controller Network Configurations

The use of KWX Wireless Transceivers provide you with flexibility in designing a controller network
configuration. The network wiring for a standard hard-wired 485 controller network appears as
shown in Figure 1. In this configuration, each controller must be connected together via daisy-
chained, RS-485 cabling.

The layout for Keri’s KWX Wireless Transceiver networks, however, can take a variety of forms,
using multiple spurs and multiple wireless units, with each network spur being independent and the
wireless unit attached at any point within the spur. This allows for shorter, more flexible network
cable runs, and makes it possible to avoid difficult cable routing locations.

NOTE: A requirement for multiple wireless spurs is that each spur be earth grounded.

Examples of multiple spur/multiple unit networks are shown in Figures 2, 3, and 4.
