DIGITAL TELEMETRY CONVERSION KIT

Information

The TEL 171 converts your Moseley TRC-15AW or TRC-15AR to digital metering transmission, a method that eliminates the offset and gain drift in the analog metering. A local display in the Transmitter control unit duplicates the readings displayed by the studio control unit. This permits one-man weekly meter calibration. The system consists of printed circuit boards which substitute directly for the audible metering generator, the audible metering demodulator, and the meter. The local display for the Transmitter control unit includes a replacement front panel and a liquid crystal display printed circuit board. installation is quick and simple since the same PC mounting hardware is used, and the same wiring harness connects to the new boards. 3 1/2 digit (-1999 to +1999) display are used. These easily read displays are updated twice a second. Should the metering carrier be lost, or a framing or parity error occur, the display at the studio will blank and a front panel LED will indicate the problem. Through the use of digital transmission and display, we eliminate the error inherent in analog transmission, and simplify the task of remote meter calibration and meter reading. Moseley, our neighbors down the road, make a good remote control. We can make it better.
