You should note in my much earlier post I indicated that our I232 Isolator System can provide communication at 115.2 kbaud up to 4000 ft.

In both directions you can transfer about 600,000 bytes per minute at 115.2 kbaud.
If you use XMODEM for transfer there is error detection and correction. If...

At rest, no data being sent, pin 2 should be about -10 V relative to pin 7. Did you have the meter connected backwards?
Assuming that you had -10 V at rest,...

It is probably equivalent to an EGA (not VGA) monitor.

RxD and TxD are data signal names. TxD is the transmit signal and connects to an RxD which is the receiver. TxD supplies the voltage and current to the cable that...

Our I232 Isolator should allow you to run at 115.2 kbaud, over a long distance, and provide electrical isolation at both ends.

Your question is unclear.
What connection exists on your CNC for communication? RS232 or what?
What do you really want to do? Think about this. Make a clear...
