Connectors
and Wiring
Figure 1-5 below illustrates the pinout of the AI-217. The AI-217 layer uses a B-
size 37-pin D-sub connector. The following signals are located at the connector:
• AIN0+ –
AIN15+ — input channel, differential mode.
Use AIN0 to –AIN15 as signal returns.
• +13
V 50mA — provides power for CJC circuitry on the optional
DNA-STP-AU accessory panel
• CJC+ —
cold junction compensation return line from DNA-STP-AI-U.
• AGND
— layer analog ground, isolated from system ground.
• EXT_
TRIG — accepts an external trigger signal to the layer.
