Hi
I bought one used very old ECG Transmitter labelled "Marquette Apex S" maybe GE, I guess from the early 2000. I am looking for in depth technical manuals or any information what protocol the serial interface works and what kind of modulation the RF transmitter uses. Or are there any field service manuals available? Or maybe someone how repaired that devices back in that years. I want to get the raw egc data without the receiver station either via serial port (if possible) or via rf-demodulation/decode...
greets
