OEM radio data modem

Utilising proven RF technology, the RDM200 yields a low cost solution for your wireless applications coupled with a fast route to market.

The RDM200 Radio Data Modem provides a transparent wireless serial link between host devices, where packets of up to 1500 Bytes of data may be transferred at a time

All data encoding, decoding and error checking is performed by the RDM200 Radio Data Modem.

The serial data sent by the host to the RDM200 is automatically encoded and packetised and then transmitted over the air to the receiving unit.

Upon receipt of the radio data transmission the RDM200 Radio Data Modem will decode the data, perform an error check and output the original data to the receiving host if the ID of the receiving unit is the same as the sending unit.
