Connections
The connections required (except power) are

While an RTU or PLC is shown in the diagram,
master stations often use a PC running an appli-
cation designed to communicate with remote
RTUs or PLCs.
master stations often use a PC running an appli-
cation designed to communicate with remote
RTUs or PLCs.
The Setup PC is used for both configuration and
local and remote diagnostics. It may be left con-
nected at all times if desired, but is not required
for normal operation once the unit has been con-
figured.

1.11.3 Common
Characteristics
The networks described below share a number
of common characteristics.
of common characteristics.
1. The network baud rate (4800 or 9600) must
be the same for all stations in a network.
2. Unless otherwise noted, the default settings
of station type is “master” and data delivery
is “all”.
is “all”.
3. Transmission of online diagnostics may be
enabled or disabled at any station or stations
without affecting their ability to commun-
icate with other stations.

frequencies with the master station transmitting
and receiving on the reverse pair from the re-
