indicator
The Rx indicator will flash whenever there is data from the Ernitec controller. If the input lines have
reversed polarity, the Rx indicator will be on solidly. Biphase code is repeating, so the Tx indicator
will continue to flash while the camera is moving.
If you have Rx but no Tx, possible causes are:
The Ernitec code coming into the translator is not camera control code.
The Ernitec data out is not set at 2400 baud.
If the code translator is sending data and does not get a follow-up Ernitec command in about 12
seconds, it will time out and quit sending that stream of data.
