RS485 For Hypertherms

Would anyone happen to have an Arduino sketch that emulates the serial modbus port of a Hypertherm PM XP ???

90 PSI or 6 Bar of pressure.

Maybe this can help:

Phill, also there are Modbus Ascii emulators that run on Windows or Linux. have a google.

Also, I think the pressures are mentioned in the manual for different types of cutting.

I am having trouble communicating with the hpmx component so i was hoping to emulate a PM XP to have a look to see what is happening.
In the Hypertherm docs they mention a CR/LF at the end of transmission from master to slave but when they mention the reply there is no CR/LF. Is this correct?

Edit: Hey Rod I see one of Toms links is from your neck of the woods.

If you are talking MoBus RTU there is no CR/Lf. It is pure hex.
( With some high level languages you have to watch carefully that they really send out the hex. In windows I had once the problem that the lower hex ones had been automatically transformed to control sequences. Grrrrr)

Only in the very old ModBus-ASCI have been with CR/LF. But that is not used often anymore...

But in this case its Modbuus ASCII
