Maxiva ULX COFDM Series
• J9 - Remote Analog Metering Outputs
NOTE:
The forward slash (/) in front of a signal name means active low. The signal
named "/INPUT 1" for example is activated by bringing that input low. Signal
names without the forward slash are considered active high. This convention is
used throughout the schematics.
2.15.1 Individual Transmitter Commands J3, J4 and J5
All control inputs use opto-isolators for surge protection. The opto-isolators are
powered by an internal +5Vdc from an isolation protection circuit.
All transmitter control functions (except Remote RF Mute, RF Switch Position A and
RF Switch Position B, which are active LOW or HIGH level input states) are
momentary ground switching and require the remote control equipment to sink at least
15mA to activate the function. The Pinouts of J3, J4 and J5 are listed in Table 2-12.
