Introduction
The pn7737 Differential Step/Direction and Encoder Board allows access to the Step/Direction channels
and more Encoder channels for the HiCON Integra (pn7766) or DSPMC (pnn7762) .
When used in tandem with a Drive Interface Board (EPx-DIB) for Maxsine AC Servo Drives, the 7737 allows
a simple plug-and-play setup using HiCON Integra and DSPMC motion controllers.
Features:
•Color-coded RJ45 plugs for Controller-to-Drive Step/Dir and Encoder cables.
•4 Differential Encoder Channels
•4 Step/Dir Output Channels
•Drive Enable and 1 General Purpose 24V NPN Outputs
•Hardware Estop and Drive Error Inputs
•Status LEDs for I/O signals.
IMPORTANT: PLEASE READ!!
pn7737 Estop Notes:
•Estop signal can be overridden by installing a jumper between Estop and adjacent
24V terminals
•Drive Enable signal is automatically disabled if Estop is triggered
•Combined Estop on HiCON Integra (between J7 and J8) signal on Port14, input15 is
preferred for Mach Estop pin mapping
•Use straight-thru RJ45 patch cables when connecting the 7737 breakout board to
the Maxsine EPx-DIB drive interface board.

VSI Device Manager Setup
The Integra J8 and J7 as well as DSPMC J11 and J12 expansion headers must be enabled for 7737
step/dir before use. To do this, open the VSI Device Manager and scan the network for your device.
Once the device is found and selected, open the HiCON or DSPMC tab, highlight the desired expansion
port and mark the value for the Enabled option. Press the Download button to send the changes to the
device. If you are only using one 7737 board, make sure to only enable one expansion header. If you
enable both headers and only one 7737 board is plugged, it will be permanently stuck in estop
condition.

Pre-requisites to get motion working on 7737 with:
HiCON Integra
The 7737 and Integra combo requires these steps for proper operation:
1. Make sure that Integra has an Extended I/O Activation.
2. Enable J7/J8 plugs for Step/Dir operation using VSI Device Manager.
3. Map the Drive Enable pin of 7737 on Mach4. Make sure the polarity is such that when Mach4 is
enabled, blue LED lights up on the 7737 Board.
4. Make sure ESTOP jumper is installed or ESTOP switch is closed on the 7737.
5. Optionally map Drive Error Signal.
DSPMCv3
The 7737 and DSPMC require these steps for proper operation:
1. Enable J5/J6 plugs for use with the 7737 in the HiCON tab of the VSI Device Manager.
2. Map the Drive Enable pin of 7737 on Mach4. Make sure the polarity is such that when Mach4 is
enabled, blue LED lights up on the 7737 Board.
3. Make sure ESTOP jumper is installed or ESTOP switch is closed on the 7737.
4. Optionally map Drive Error Signal.

Note About Servo Alarm Output: For normal operation, the alarm output from the drive should be ON
(active). When the Alarm output is OFF (open circuit) the 7737 reads it as a fault condition. You can
override the fault condition by installing the jumper on J4 Drive Error override. We recommend you
install the jumpers for all unused Drive-Error signals.
