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...

If standard 1488 and 1489 interface chips are used, then these are extremely reliable if you do not exceed their ratings. However, lots of these fail because...

speedrider:

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...

Whether you have an open or closed delta does not matter and HAAS will work with either. What you have is a delta with one center tapped secondary for your single...

I do not have any machines with this function. What specific information do you want to extract, and how often? What commands do you expect to run? Do you plan to...

Elaborate on your question. What is setting 143 so I do not have search for what it is? What year is your machine? What data do you want to collect and how would it...

I probably disagree with your statement on length's effect on hardware vs software, but I do not know. That is why the question. I do disagree based on...

Please explain why a long RS232 cable is a problem for software handshake. Assume operation at 115.2 kbaud, and your concern is the cable time delay. This is...

When I use the term G52 is added to G5x it does not mean that G5x is modified.

What it means is that internally there is some set of computer registers that represent where...

In HAAS or Fanuc mode this is a very useful function.

There are memory registers for each axis for G52, G54 .....

You need more detail in your question.

I did not get all the residual load off. However it was moderately small. I Used a 1500 watt resistive load. If the...

If your meter has a rotating disk you can use it as a power meter.

Shut off all power in your house, clocks do not matter. The disk should be virtual still. Connect...

Do a calculation on wire cost vs transformers.

I would favor a 240 delta with a wild leg. This has one pole transformer center tapped with the center tap the nuetral. This...
