CHAPTER 3
EXAMPLE APPLICATIONS
PLC Emulation Applications
The ESTeem 195C and 195M can support PLC based networks in both point to point and multipoint applications. The PLC
emulation driver allows the ESTeem to identify the destination address in the PLC message block and change the ESTeem
destination address to match. This PLC emulation allows the ESTeem 195C/M to support multiple repeaters in a network
(Figure 4). If repeaters are used with PLC emulation, the route and append table will also need configured (see Chapter 4 for
complete details).
