TDi2 interface board enables a cable free transparent data link between RS232
ports without any additional interface circuitry.
The interface board feature an on board TDL2A-433-9 OEM serial modem, MAX232 RS232 driver, 9
way D connector, 5V voltage regulator and SMA RF connector, hence requires just a Voltage supply to
power up and operate without any additional interface circuitry. The TDL2A modules would be soldered
directly on to the interface board for better grounding and to improve RF performance. The helical
antenna and the SMA connector shown are optional. User could also use a two pin terminal block
instead to mount a 1/4 whip antenna made of piece of wire or metal rod.

... Configuring the TDi2 In order to use all the functions embedded in the on board TDL2A modem, the user must be aware of the setup /programming facility, which allow different addresses and frequency channels to be set up, and if necessary accesses diagnostic test modes. The TDi2 is programmed through the same RS232 port that is used for sending/receiving data. An RS232 terminal emulator (such as Aterm or HyperTerminal ideal tool ...

... R8 connects STATUS (data ready, via an RS232 buffer) to DCD, DSR and CTS. Not linking this jumper (LK2 at the back of the board) saves power. The SIG LED is provided for visual indication of STATUS data ready. This LED would lit when a valid data is present in the receive buffer.
