3 INTERFACING
The PCM-DAS08 has eight single-ended analog inputs with an analog ground, one
digital input with shared function as A/D trigger input, two digital inputs, and three
digital outputs. A digital ground is in the cable shield clips to either side of the 15
pins of the connector.
3.1 CONNECTOR
Figure 3-1 shows a PCM-DAS08 card looking into the connector. The KEY insures
that the cable is inserted correctly.
Analog signals should be connected with the high side to the numbered analog input
and the low side to the analog low level ground.
Do not connect digital signal grounds to the analog ground. Use the cable shield.
