Operation Theory 75

Note that when power-up or reset, the DAQ timing signals are

reset to use the internal generated timing signals.

AI_Trig_Out and AO_Trig_Out

AI_Trig_Out (or AO_Trig_Out) is the signal output following one of

the four trigger sources: software trigger, analog trigger, digital

trigger, and SSI trigger selected by the user. That is, AI_Trig_Out

follows the A/D trigger source, and AO_Trig_Out follows the D/A

trigger source. These two signals can be used to control external

peripheral circuits or boards, or can be used as synchronization

control signals. The signal level of the AI_Trig_Out and

AO_Trig_Out are TTL-compatible.

NOTE AI_Trig_Out and AO_Trig_Out are output pins on J5 (68-

pin VHDCI). Connecting them to any signal source may

cause permanent damage to the card.
