Looking to finally wire up my PMDX-122 to my four IMService Driver cards. Here are a few pictures of all of them. Any help would be greatly appreciated- If someone can come up with a wiring diagram, that would be incredible! Here is a link to the PMDX's manual.
Bump, really need some help!
Hey burn, it seems pretty straightfoward. On your breakout board each of the pins correspond to a number of pin from you parrallel port. So, pins 2&3, 4&5, 6&7 would run from the breakout board to the step and direction pins on your drivers. Pins 2,4,6 would run to the corresponding step on your drivers, x being number 2, y being 4, z being 6. The Direction pin would then run from 3,5,7 on your breakout board to again the pins on your drivers, x being pin 3, y being pin 5, z being pin 7. Your servo boards have the abbreviation stp and dir for step and direction. Because your servo boards use a particular connector you would either have to solder the wire directly to each pin or find a connector that would work. You could prolly find the connector at any good electronics hardware shop. What other questions?
Thanks for the help PizzaMaker
Got an email from Steve Stallings over at PMDX:
Based on Fred's comment about 500 mA typical power
consumption for his boards and encoders, the PMDX-121
cannot supply the 5 volts.
You can use power from a disk drive connector in the
computer but I would recommend an independent power
supply. The ground lead is typically black and should
connect to the GND terminal on J8 of the PMDX-121
and to the GND of the middle connector of the servo
board. The 5 volt lead is typically red and should connect
to the "+5 Aux Out" terminal of J8 on the PMDX-121 and
to the +5v terminal of the middle connector on the servo
board. The encoder will get its power from the connector
on the servo board. Even though the terminal on the
PMDX-121 is labeled "+5 Aux Out", it is permissible
to supply regulated 5 volts into the board on this pin. Do
not connect an unregulated supply or AC to this terminal.
JP1 on the PMDX-121 should be set to the GND position
for use with these servo boards.
