Features
The PMDX-132 has the following features:
PC Parallel Port:
•
Buffers signals to/from the PC parallel port
•
Allows use of all 8 data bits, 4 control outputs
and 5 status inputs
•
Centronics cable connector uses standard PC
printer cable
•
Ribbon header for optional cable to 25-pin
“D” connector or devices with compatible
ribbon connectors such as the SmoothStepper
Status Inputs:
•
5 each status inputs w/pull-up resistors
•
Status signals are isolated and buffered
•
LED indicators for each input
Control Outputs:
•
4 each general purpose digital outputs
•
2 outputs may also drive relays with N.O and
N.C. terminals
•
Outputs are isolated and buffered
•
LED indicator for each output
Gecko Stepper Driver Interface:
•
4 axes of step and direction
•
Driver fault sensing
•
Buffers signals to drive step & direction inputs
•
Sele5V or GND step/dir common
•
Wire clamp terminals for the current set
resistors
Power Supply Input:
•
120 or 240 VAC input for logic supply
•
Separate DC supply input for motor drivers
Special Features:
•
Pluggable wire clamp terminal strips for I/O
connections from parallel port status and
control signals

2.0 Quick Setup Guide
2.1
Package Contents
Each PMDX-132 ships with the following items:
1 each PMDX-132 circuit board
4 each 4-position plug-on terminal strips (use on the Geckodrive modules,
not
on the
PMDX-132)
6 each Nylon standoffs, 1-1/4” with 4-40 thread (use to mount the PMDX-132 and Geckodrive
assembly to a heat sink plate)
Note that the PMDX-132 ships without plug-on terminal strips for its connectors (J3, J4, J8, J9 and J10).
You will be re-using the terminal strips from the Gecko stepper driver modules for the PMDX-132
connectors as described below.
2.2
Assembly steps
1.
Remove the pluggable terminal strips from each of the Gecko stepper driver modules (these should
be 2 sections of 6-pins each)
2.
Install the 6-position terminal strips onto the PMDX-132 connectors J3/J4, J8, J9 and J10. Note that
the connectors J3 and J4 are combined into a single 6-position terminal strip.
