National Instruments 1128 用户手册

1.

Install the HVAB-backplane adapters and jumper blocks in the 12-slot 
chassis as described in steps 1 through 3 in 

2.

Connect the HV8-HV8 cable from the first chassis, normally the 
connector behind slot 1, to the HVAB connector (behind slot 12) of the 
next chassis.

3.

Connect the SH9MD-9MD cable from the AUX OUT connector of the 
first chassis to the AUX IN connector (behind slot 5) of the next 
chassis.

4.

Repeat steps 1 through 3 for each additional chassis.

Do not use the SH9MD-9MD cable behind slot 4 of the 2-slot HVAB-backplane 

adapter on the 12-slot chassis.

An SCXI-1127/1128 is required in slot 4 of the 4-slot chassis and slot 12 of the 12-slot 
chassis to establish communications with all the chassis in the system. If slot 4 is empty 
in the 4-slot chassis or slot 12 is empty in the 12-slot chassis, the chassis will not operate. 
It is this module that you must specify in MAX as the module cabled to the DMM.

If the 4-slot chassis is configured with less than four slots of the HVAB-backplane adapter, 
use the right-most available HVAB connector to extend to the next chassis. In this instance, 
right-most means the slot closest to slot 1 when the chassis is viewed from the back.

In addition to the items needed for a single-chassis system, you need the 
following items to install this configuration:

•

SCXI-1358 multichassis expansion kit

–

HV8-HV8 cable

–

SH9MD-9MD cable

–

Three 8-position HVAB plugs

–

One 8-slot HVAB-backplane adapter

–

One 2-slot HVAB-backplane adapter

–

Two 1-slot HVAB-backplane adapters
