RMX232 : RS232 Wireless Serial Radio Modem
Product Description
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 for VHF and 9600bps for UHF.
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 and 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 2400/9600 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 and range testing.
