single-ended cable (NI part number 152629-0x)
–For NI hardware with mini HDMI connectors: SHH19-MH19-AUX shielded single-
ended cable (NI part number 784091-01)
Note The specified performance of the AUX I/O connector is not guaranteed
if a third-party HDMI cable is used. Use one of the recommended cables for all
AUX I/O connections.

Getting Started with the SCB-19
Complete the following steps to connect and use the SCB-19 with NI hardware:
Install your NI hardware in a chassis. Refer to the hardware documentation for your product(s)
for installation instructions.
1.Remove the four cover screws with a Phillips #1 screwdriver and open the top cover, as
shown in Figure 1.
2.Connect wires to the screw terminals.
Caution To ensure the EMC performance specified for the connected
hardware, 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.
a)Strip 6.35 mm (0.25 in.) of insulation from the wires.
b)Insert the wires into the screw terminals.
c)Securely tighten 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.).
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.
3.Close the top cover and tighten the four cover screws.

Caution Refer to the documentation for the hardware you connect the
SCB-19 to for maximum voltage specifications. Using voltages outside of the
specified range could damage the SCB-19 and any instruments connected to it.
NI is not liable for any damage resulting from using voltages outside of the
recommended range.
Connect the SCB-19 to the AUX I/O connector on your NI hardware using an
SHH19–H19–AUX or SHH19-MH19-AUX cable and tighten the target screw, as shown
in the following figure.

When you have finished using the SCB-19, power off any external signals connected to the
SCB-19 before you power off your computer.
Caution Clean the hardware with a soft, nonmetallic brush. Make sure that the
hardware is completely dry and free from contaminants before returning it to
service.

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 15.88 mm
(0.625 in.).
