The TDM2 is a very simple 433MHz band radio data modem. It provides a medium ranged half duplex, transparent data link between a pair of 9600 baud RS232 ports without any additional interface circuitry.

The TDM2 is a TDL2A radio module, combined with suitable interface circuits, power supplies and connectors, packaged in an attractive instrument case. In the simplest case, a pair of 'box modems' (with suitable aerials and power supplies connected, of course) can be connected directly to the serial ports of a pair of industrial PCs and the resulting wireless data link used without any further installation or programming.
