• C a b l e or wires to connect the handshaking lines to the SCXI-1127
• 1 / 8 in. flathead screwdriver
Consult the documentation for your SCXI chassis and other SCXI modules
for additional instructions and warnings. You should have installed your
SCXI-1127 modules according to the instructions given in
Installing the
SCXI-1127 Module into the SCXI Chassis section. Any other SCXI
modules should already be installed according to their installation
instructions. To install the SCXI-1127 module with an SCXI chassis,
follow these steps.
1. I n s t a l l the SCXI-1127s in the chassis and install the HVAB as
described in one of the Connecting the SCXI-1127 backplane sections.
2. T o connect an SCXI-1127 to an external DMM device, you need two
cables—the HV8-BAN4 or BAN2-BARE cable, and a cable to connect
the handshaking lines from the SCXI-1127 to the DMM. Attach your
HV8-BAN4 cable to the HVAB connector on the HVAB-backplane
adapter or connect your BAN2-BARE cable to the OUTO terminals on
the SCXI-1331 terminal block. When making four-wire measurements
you must also connect a BAN2-BARE cable to the OUT2 terminals.
3. A t t a c h the other end of the HV8-BAN4 or BAN2-BARE cable to the
inputs of your external DMM device.
4. Connect the handshaking lines from the front of the SCXI-1331
terminal block to the appropriate lines on the external DMM. See
Chapter 2,
Handshaking Scanning, for information on how to use the
SCXI-1127 handshaking lines.
5. C h e c k the installation.
6. T u r n on the SCXI chassis.
7. T u r n on the computer or reconnect it to your chassis.
The SCXI-1127 module is now installed.
Note F o r the system to function properly, it must either be controlled by a DAQ device
or be a 2000 series SCXI chassis.
