TX/RX-EVAL FM Transmitter & Receiver Evaluation Boards

The TX-EVAL transmitter evaluation kits permit the evaluation of and testing of all the TXM series transmitters.

This unique board accommodates 3V, 5V and 9V operating transmitters at the flick of a switch. It also permits

the transmission of data from an on-board HT-12-E data encoder, to which data bits D0 - D3 may be altered

using a dip switch. Push to transmit or continuous transmission modes are also provided. Antenna connection

is via a BNC socket permitting the connection and evaluation of a wide variety of antenna styles. Note it is up to

the user to ensure that maximum ERP regulations are not exceeded.

The RX-EVAL receiver evaluation kit permits the evaluation and testing of the SILRX series and RXM series of

receivers. It contains HT-12-D data decoder, for which LED's are provided corresponding to valid data received

and data bits D0 - D3 and indicate POWER and RF CARRIER presence. A signal strength meter is also

provided which is driven direcly by the RSSI output of the RXM receiver module. Note this facility is not provided

on the SILRX receiver module. An earphone socket is available to listen to the received signal. As with the TX-

EVAL, antenna connection is via a BNC socket permitting the connection and evaluation of a wide variety of

antenna styles.

Both evaluation boards are powered by 9V batteries (not supplied). Sockets are provided enabling the module-

under- evaluation to simply plug in, thus eliminating the need for soldering.

The respective transmitter and receiver modules are purchased seperately.

TX-EVAL RX-EVAL

These boards have been designed specifically to enable the newcomer and experienced engineer alike to get a

feel for the capabilities for each radio data module under both laboratory and field conditions. Their features

provide an invaluable means for conducting range tests and for assisting in installation and the alignment of

antenna.
