Configuring the Raven at the Polling Host for
Modbus on UDP
You can use either Wireless ACE (page 15 and page 57), direct serial communica-
tion or Telnet (page 58) to configure the modem using AT commands (page 61).
This section covers standard Modbus, variations may need additional commands
(AT Commands: page 87).
Port
The destination port for the Raven at the host needs to match the device port in use
on all the Ravens at the remote sites. For example, if the remote Raven’s device
port (see below) is "12345", then the Modbus host Raven's S53 (AT commands:
page 103) destination port should be set to "12345".
In Wireless ACE, select Misc in the side menu.

Take note of (or set) the Device Port setting in *DPORT (AT commands: page 103)
to configure the remote Ravens.
