Getting Started with the SCB-19
Complete the following steps to connect and use your SCB-19 with your NI device.
1. Install your NI device in your chassis. Refer to your device documentation for installation
instructions.
2. Remove the four cover screws with a Phillips #1 screwdriver and open the top cover, as
shown in Figure 1.
3. Connect wires to the screw terminals by stripping 6.35 mm (0.25 in.) of insulation, inserting
the wires into the screw terminals, and securely tightening the screws with the flathead
screwdriver to a torque of 0.5 N · m to 0.6 N · m (4.43 lb · in. to 5.31 lb · in.).
Caution To ensure the EMC performance specified for the connected device, any
wires connected to screw terminals that exit the enclosure must be shielded.
NI recommends using a multiconductor cable with an overall shield. Terminate the
cable shield to one of the PCB mounting screws.
Note The top row of screw terminals corresponds to the DIO and PFI signals on the
AUX I/O front panel connector. The bottom row provides ground terminals.

Tip You can neaten the wires and provide mechanical support by sliding a cable tie
through one of the slots shown in Figure 2, wrapping the cable tie around the wires,
and tightening the cable tie.
4. Close the top cover and tighten the four cover screws.
Caution Refer to your device documentation for maximum voltage specifications.
Using voltages outside of the specified range could damage the SCB-19 and any
devices connected to it. NI is not liable for any damage resulting from using voltages
outside of the recommended range.
5. Connect the SCB-19 to the AUX I/O front panel connector on your NI device using an
SHH19–H19–AUX cable (NI part number 152629-0x) and tighten the target screw, as
shown in Figure 3.
Figure 3. SCB-19 Cable Connection
Caution Although the AUX I/O front panel connector accepts a standard HDMI
cable, a standard HDMI cable causes significant crosstalk between some channels.
Use the SHH19–H19–AUX cable to minimize crosstalk.
When you have finished using the SCB-19, power off any external signals connected to the
SCB-19 before you power off your computer.

SCB-19 Mounting Holes
You can mount the SCB-19, either vertically or horizontally, on a DIN rail in an industrial
environment. You can purchase a compatible DIN rail kit from NI using the part
number 781740-01.
The SCB-19 also has two screw holes for a generic wall mount. These wall mount holes are
designed for use with a #4 or #6 panhead screw with a minimum length of 0.625 in. (15.88 mm).
Figure 4 shows the screw holes locations on the bottom of the SCB-19.
