The ELPRO 915U-D Wireless Serial Modem is an RS232 or RS485 data
modem that enables cost effective, two-way communications between
serial devices such as PLCs, RTUs, and other industrial machinery to host
monitoring and control systems. Designed with a long range, license-free
900MHz or 2.4GHz wireless transceiver, the ELPRO 915U-D delivers high
performance in a compact DIN-rail or panel mount form factor ideally suited
for integrated industrial applications.
