RMX232-151.600 Serial Radio Modem


The RMX232 Radio Modem provides a reliable wireless communications link between two serial devices. The RMX232 can be used in a variety of data communications applications that require a simple to use invisible data link.

The RMX232 permits point-to-point error free transfers upto 2400bps half duplex.

Repeater mode enables the Radio Modem to extend the effective operating range of a point-to-point link by forwarding data packets to a single repeater hops.

The Radio Modem uses unit & site addressed data packets with error checking and packet acknowledgements to achieve a well managed highly reliable wireless link. The on-air data rate is selectable from 600 to 2400 bps, thus improving network access for multiple point-to-point links within close proximity.

Configure the RMX232 for point-to-multipoint broadcast mode and combine with any number of intelligent host computers/ controllers to implement very large networks.

The RMX232 Radio Modem supports a range of built-in diagnostic functions that can be used for network interrogation, network problem finding and radio site & range testing.
