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.

Connecting the DCM to Power
Powering the DCM with the DCM Starter Harness and PDU-2300 requires a 12 V or 24 V, 180
W minimum, external DC power supply. Recommended power supplies are listed in Table 1
below. The light-duty power supply leads (14 AWG) included in the DCM Starter Harness kit
are recommended only for bench-top applications which require less than 15 A of current. The
heavy-duty leads (8 AWG) included in the DCM Starter Harness kit are recommended for all
other applications.
What to Use
• Starter harness light-duty (<15A) or heavy-duty power supply leads
• Wrench, 1/2-in.
• NI recommended power supply

What to Do
Complete the following steps to connect power to the DCM.
• Ensure the DCM Starter Harness is connected as discussed in the Connecting the DCM
Starter Harness section.
• Connect power supply leads terminated with properly rated ring terminals to the PDU
Positive (+) and Negative (-) input studs.
• Tighten terminal fasteners to 10.2 N · m (90 lb · in.) using a 1/2-in. wrench.
• Connect power supply leads to the power supply. If connecting to a battery, always connect
the Negative (-) lead last. When disconnecting the battery, always disconnect the
Negative (-) lead first.
Connecting the DCM to the Host Computer
Complete the following steps to connect the DCM to the host computer or Ethernet network
using the RJ-45 Gigabit Ethernet port.
• Power on the host computer or Ethernet hub.
• Connect the RJ-45 Gigabit Ethernet port on the DCM to the host computer or Ethernet hub
using a standard Category 5 (CAT-5) or better shielded, twisted-pair Ethernet cable.
Caution To prevent data loss and to maintain the integrity of your Ethernet
installation, do not use a cable longer than 100 m (328 ft).
Note The DCM attempts to initiate a DHCP network connection the first time you
connect using Ethernet. The DCM connects to the network with a link-local IP
address with the form 169.254.x.x if it is unable to initiate a DHCP connection.
Powering on the DCM
When you power on the DCM for the first time, the device boots DCM DSI. The POWER LED
illuminates, the STATUS LED illuminates briefly, and then the USER1 LED blinks steadily
once the DSI executable has booted. Overall boot time is approximately 60 seconds.
Configuring the DCM in Measurement and
Automation Explorer (MAX)
Complete the following steps to find your DCM in MAX.
• Ensure that any anti-virus or firewall software running on the host computer allows
connections to the host computer.
Note MAX uses UDP 44525. Refer to the documentation of your firewall software
for information about configuring the firewall to allow communication through
UDP 44525.
• Launch MAX on the host computer.
