Multiple-mode, RS-232/RS-485 serial data networking
Description
ELPRO multiple-mode wireless serial modems allow transparent
communications between RS-232 and/or RS-485 serial host devices.

example, specific unit addressing.
The 455U-D is a full-functionality RS-232/RS-485 modem, supporting
addressed/broadcast modes and optimal path routing for Modbus®
RTU, DF1 and DNP-3.
