Features of the PMDX-411 Rev A
1) Motion controller inside the shell of a male DB-25 plug that connects directly to the female DB-25 on a PMDX-340, the Geckodrive G540, and many breakout boards including the PMDX-126. You can use a simple gender changer if you need to mate with a DB-25 male. You can also connect directly to stepper drivers and simple switches with just a wire harness.
2) The motion control pulse engine generates pulses independent of the host computer timing and provides real time control for smooth step pulse signals up to 100 KHz on 4 axes.
3) Simple USB connection to the host computer supports both CNC operation and firmware updates.
4) Power is supplied via the USB connection so no power supply is needed.
5) The PMDX-411 provides equivalent signals to one parallel port including 8 step and direction signals, 5 input signals including one dedicated to emergency stop, and 4 output signals.
6) The inputs are compatible with 5 volt or 3.3 volt logic signals. These inputs are also equipped with pull up resistors so that they can be used with directly connected mechanical switches or NPN sensors.
8) The step and direction outputs are 5 volt logic signals with up to 24 mA of drive current available. In addition to interfacing to a breakout board, they can also directly drive the step and direction inputs of motor drivers.
9) The 4 control outputs are also 5 volt signals with up to 24 mA of drive current available. In addition to interfacing to a breakout board, these signals can also drive solid state relays.
10) All outputs are turned off in the event of loss of communication from the host, or if the emergency stop input is activated.
11) Two externally visible LEDs show the status of host connection and the SmartBOB-USB board.
12) The USB connection is provided by a 16" long cable with a USB style A male connector that can plug directly into a computer.
13) Using a directly attached pigtail cable avoids having a fragile mini-USB jack inside the PMDX-411 that can be damaged by pulling on the cable.
14) Convenient thumb screws allow the PMDX-411 to be firmly attached to your breakout board or driver box.
15) The cable length can be extended to 15 feet using good quality USB A-to-A extension cables such as our PMDX-USB-AtoA-Extension.
PLEASE NOTE: The available step and direction signal pinouts work with most common breakout boards and with the PMDX-340 and Geckodrive G540, but they are not totally assignable at random. Please verify that your device is compatible before purchasing. Available configurations are Step on pins 2, 4, 6, 8 and Direction on pins 3, 5, 7, 9 <<OR>> Step on pins 3, 5, 7, 9 and Direction on pins 2, 4, 6, 8.
