JR9XII / 9303 modular connector

Post by Daniel Wee »

The JR modules uses a 5-pin connector for their transmitting modules. These carry power and the PPM/PCM signal that the module needs to send out the RF signal, and returns it to the antenna.

The PPM signal at the connector has a rail-to-rail swing, unlike the one that you find at the D.S.C. port.
