Which part was the most helpful? I just want to refine the document a bit more.

Your old diagram really helped me figure mine out...

that Hypertherm diagram clearly seems to show the right hand side is an ordinary 9 pin serial port. The Hypertherm has more pins than most RS485 devices require. RS485 is a protocol not a wiring standard. So maybe an adapter is not required.

Phill,
The more I thought about it the more I liked the Hypertherm mapping diagram so I modified the reference document to show it. I think it looks better - please find attached.

The part that showed from the Hypertherm to the BOB, since they are named different things on the hypertherm diagram, it helped me get to the correct wiring much faster.

When you say "adapter" do you mean the break out board, or the RS-232 to RS-485 converter? Because I tried it without the converter in every wire combination humanly possible... it wont work.
The RS-485 for hypertherm uses 4 wires because it is in Full-Duplex. Half Duplex RS-485 only requires 2 wires. So the wiring can change with the protocol's use a bit.

Read the label in the picture its showing attached to a standard PC DB9 serial port on the right.

So your saying just use a DB9 male connector instead of the adapter when using a PCI card? If so I agree with that but I had the screw terminal adapter handy.

I found the breakout board FAR easier as well.
Maybe just add a little section "if using a breakout board" and have the table you had before...

I'll let you guys figure out what it should look like, maybe also ask Clive what helped him.

You used to be able to get DB9 connectors that came with seperate wires and pins so you could make whatever pinout you want and just plug in an ethernet cable. I never soldered up a DB9 again! I bought from Haymans electrical wholesalers in Australia.
