DIO connector. These lines correspond to Slots <0..15> on an SSR
backplane in sequential order. You can connect to an SSR backplane
containing a number of channels unequal to the number of lines on the
NSC68-5050 cable header. In this case, you have access only to the
channels that exist on both the SSR backplane and the NSC68-5050 cable
header you are using.
Figure B-4 shows the connector pinouts when using the NSC68-5050
cable.
