Configuring Modbus/BSAP
The remote Raven then disassembles the packet before trans‐
mitting the RTU ID and serial data to the remote unit. The
remote units operate in normal UDP mode and their data is
sent to the host via the remote Raven and host Raven.

The destination port for the modem at the host needs to match
the device port (*DPORT) in use on all the modems at the
remote sites. For example, if the remote modem's device port
(*DPORT) is "12345", then the Modbus host modemʹs S53
destination port should be set to "12345".
Take note of (or set) the Device Port setting in *DPORT to
configure the destination port on the remote modems.
