From the Haas manual:
Hello, Been using bluetooth serial devices for higher baud rate transfers, but they knock out the wireless internet and are spotty as far as reliability.
Constantly having to mess with them.
The plan is to switch to Lan based serial server devices, Neteon GW-212 but can't seem to get the connection working.
As I recall from way back when we wired directly from the com ports, (lower baud rates) there is some pin switching that needs to happen for the transfer to be understood by the haas. Why they wired it this way is beyond me?
Saw something on this in another post but it's not clear enough to understand from what I can tell. I will keep searching.
Anyone familiar with the correct pin swaps that need to happen?
(these are the older Haas machines without Ethernet)
Thanks so much!

Awesome thanks for that, yes finally found it late last night, in all places, in the PDF version of the manual! : )
Will update once I get it all up and running!
Thanks very much for your reply dcoupar!
Oh and one other thing I learned, it looks to be a "null modem" cord or adapter that is needed.. Going to solder it up first and try the adapter later once it gets here. : )
Thanks Mike,
Yes but hate to have to splice and re-solder the standard cable. The device I am using is the opposite from what the diagram shows. (Tx is pin three on the serial server, Rx is pin 2) This is standard rs-232 format from what I can tell...
Was hoping a nulll modem adapter would fix that without having to do surgery and make a custom cable for 6 machines...

Actually rx and tx match up properly standard cable. (apparently I am dyslexic). However pin one on db9 shows up at pin 8 of db25. Also pin 7 shows up as pin 4 on db25, which means I guess custom cable is inevitable? Wondering why in the world they did not stick to standard cabling? Waiting for service guy to call to verity..
UPDATE: Haas serviceman who deals with the RS232 was out until Thursday, but yes requires special cable which haas supposedly offers. Will see if I can overcome my dyslexic tenancies and get it right in the meantime to at least verify these devices are going to work at high baud rates at long distances. : )
UPDATE 2:
Ok, got the multi meter out again, apparently IT IS it's a standard cable. My bad. Will see how it works out with the devices soon.: )
Thanks for the replies!

Null modem cable will work. I've used them on several machines.
Hello Cadmaker,
That's what I thought but looks like from what I can tell from using the multi meter, a standard cable works. Also it says on page 25 of the HAAS electrical service manual I just downloaded that a null cable won't work.
Perhaps you had a null cable or adapter coming out of the computer and the null you are using is converting it back to standard? Anyways, I think I am all set for now.
Thanks for the replies!
