Mounting
The SC-2051 adapter is equipped with metal standoffs so it can sit on a
workbench close to the host computer. A rack-mount is also available and
can be fitted with a flat acrylic plastic cover or metal wraparound cover. To
ground the SC-2051 adapter to the chassis, set the jumper on the adapter as
described in Chapter 10,
.
Cabling
You need a 50-pin ribbon cable to connect the SC-2051 to a DAQ device;
the cable needed depends on the DAQ device. Connections to the SC-206X
Series boards require a 26-pin ribbon cable. A 26-conductor ribbon cable is
needed for the 8-channel SSR backplane. Additional cables are available
from National Instruments for connection to other accessories.
