General Mach Discussion / PMDX and extra parallel port?
« on: May 14, 2011, 10:45:40 AM »
I bought a PMDX 126 board. After looking at the manual on it, it says you can run it to (2) parallel ports for the extra I/O 's. Or you can run it in expanded mode and get the extra I/O's through one port.
I want to set it up so extras can be added later as needed. It would be aggravating to get it running and tuned, then need to add some items, and have to start over.
My second parallel port is the one Simpson recommended here:

It isn't installed, yet.
Another problem is my pendant:

It connects through a 2nd parallel port, using the c22 card:

Now does this mean I need (3) parallel ports?
? 
Is that even possible or just crazy?
Maybe I'm making this too complicated. I don't want machine looking like the space shuttle wiring.
Could I use the (2) parallel ports. One for the pendant, and the other for the PMDX 126 board ( running it in the expanded mode)?
This something that needs to be figured out now before the B_O_B in mounted.
Maybe it is intimidating because I'm a newbie at this. That PMDX board is nice, but the instructions are a little intimidating to me. The more you read it the more sense it makes.
I have the Gecko booklet next to me, and checking where it all goes.
Thanks a lot,
Let me know if this is an overcomplicated mess, or something needs to be changed before I get too far along.
