GETTING STARTED GUIDE
NI DCM-23XX
Embedded Direct Injector Control and Measurement (DCM) Device
with Real-Time Processor and Reconfigurable FPGA
Hazardous Voltage This device sources hazardous voltages up to 250V. You must
take the following precautions. A hazardous voltage is a voltage greater than 42.4
Vpk voltage or 60 VDC to earth ground.
Caution Ensure that hazardous voltage wiring is performed only by qualified
personnel adhering to local electrical standards.
Caution Do not mix hazardous voltage circuits and human-accessible circuits in
the same cable unless the cables are properly insulated for min. 250V.
Caution Ensure that devices and circuits connected to the module are properly
insulated from human contact.
Caution Except for the isolated RS232, CAN, IGND, IO Lock terminals, and the
Ethernet Port, all I/O terminals are hazardous voltage LIVE (> 42.4 Vpk/60 VDC) or
could be at hazardous potential. You must ensure that devices and circuits connected
to the module are properly insulated from human contact. External protection must
be provided to protect any other devices connected to the BATT, DRVP, and MPRD
supplies.
Caution Do not operate the DCM in a manner not specified in this document.
Product misuse can result in a hazard. You can compromise the safety protection built
into the product if the product is damaged in any way. If the product is damaged,
return it to NI for repair.
Caution Do not disconnect the power supply wires and connectors from the
controller unless power has been switched off.

Required Components (Not Included)
The following items are necessary to set up and use the NI DCM using this document:
• Host/Development PC running Windows 7/8.1/10
• DCM Starter Harness
• PDU-2300
1
• 12 V or 24 V DC power supply, 180 W
minimum DC power supply
Software Installation
The DCM may be used with several different software personalities. Each personality requires
different software packages to be installed on the host computer which may need to be
individually licensed.
NI Powertrain Controls supports the following software personalities for the DCM:
• DCM Default Software Image (DSI)
• NI LabVIEW
• NI VeriStand
DCM Default Software Image (DSI)
Before using the DCM DSI, you must install the following application software and device
drivers on the host computer in this order:
• NI CompactRIO Device Drivers 16.0 or later
• Software Calibration Management (SCM) Toolkit 2016 or later (evaluation license)
Note The DCM is shipped supporting the latest version of SCM. If you have
trouble launching the DCM DSI with the latest available version of SCM on
the software on your DCM may need to be updated. Refer to the NI DCM-23XX DSI
User Guide for more information.

Hardware Installation
Mounting the DCM
The DCM is designed to be flexible in its mounting position. The following mounting methods
are supported by NI Powertrain Controls:
• Rack-mount: Rack-mounted in a standard 19-in. chassis, 5U
– Requires: Rack-mount kit (included, PN: 785246-01)
• Panel-mount: Firmly secured on a clean, flat surface with connector facing out or up
– Requires: Panel mount kit (optional, PN: 785247-01)
Connecting the DCM Chassis Ground Lug to Facility
Ground
You must connect the DCM chassis ground lug to the grounding electrode system of the facility.
What to Use
• Wire, 1.63 mm2 (14 AWG) or larger, or braided grounding strap
• Screwdriver, flat 3/16-in.
4 | ni.com | NI DCM-23XX Getting Started Guide
What to Do
Complete the following steps to ground the DCM.
1. Remove the screw from the chassis ground lug on the DCM.
2. Insert wire or braided grounding strap into the side of the chassis ground lug
3. Tighten the grounding screw to 1.4 N · m (12 lb · in.) of torque.
4. Attach the other end of the wire to the grounding electrode system of your facility using a
method that is appropriate for your application.

the devices as shown in Figure 1.
What to Use
• DCM Starter Harness
• Hex Driver, 4 mm
• PDU-2300
• Emergency Stop (E-Stop)
What to Do
Complete the following steps to connect the DCM Starter Harness.
1. Ensure that the PDU is disconnected from all power sources.
2. Connect the harness to DCM Connector 1, being sure to orient the connector appropriately.
3. Tighten the DCM connector terminal fastener to 5 N · m (44 lb · in.) of torque using a 4 mm
