The WM-IIRO-8 is an intelligent 8-bit parallel digital I/O unit that communicates with an ACCES Wireless Serial Modem (sold separately) via a 900MHz wireless connection. Up to 255 devices can easily be used with one Wireless Serial Modem which connects to a host computer’s standard COM port using RS-232 (or RS-485) serial communications. Both the WM-IIRO-8 and Wireless Serial Modem are packaged in small, rugged, NEMA4 enclosures; perfect for remote installations in harsh atmospheric, industrial, or marine applications. The unit offers a low-cost alternative to costly signal wire installations in applications such as agricultural and irrigation systems, building management and control, security, and factory automation.
