Mounting
The SC-2050 adapter is equipped with metal standoffs so it can sit on a
workbench close to the host computer. A rack-mount chassis is also
available and can be fitted with a flat acrylic plastic cover, or a metal
wraparound cover. To ground the SC-2050 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-2050. Connections to the
SC-206
X
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.
