2.14.1 Transmitter Control Functions, J13 and J14
All control inputs use opto-isolators for surge protection. The opto-isolators are
powered by an in5Vdc from an isolation protection circuit, U54.
All transmitter control functions (except Remote RF Mute) are momentary ground
switching and require the remote control equipment to sink at least 15mA to
activate the function. The Pinouts of J13 and J14 are listed in Table 2-3.
