805U-D Wireless Serial Modem
RS-232/RS-485 serial data networking
Description
The ELPRO 805U-D Wireless Serial Modem is a robust, license-free
serial transceiver capable of long-range communications to 10 km
(6 miles). Operating at 869 MHz and up to 500 mW, the ELPRO
805U‑D provides high-speed RS-232 and RS-485 connectivity up to
76.8 kbps, providing robust and secure two-way wireless serial com-
munications in challenging environments typical of industrial monitor-
ing and control applications.
Capable of high-speed communications with serial devices, the
ELPRO 805U-D can communicate using either transparent broadcast
mode or a controlled addressed mode. Both offer node-to-node,
node-to-multi-node and repeatability for greater range. Integrated
forward error correction maximizes bit error rate, providing greater
transmission reliability. A configurable DTR-controlled low-power
mode on the RS-232 port reduces overall power consumption.
Approved for use in hazardous areas, the modem delivers strong
resistance in harsh industrial environments.
