EXTERNAL TRIGGER
The EXTERNAL TRIGGER BNC connectors B17 and B18 are provided for applications that require external digital triggering of the
data acquisition board. These connectors could also be used in applications requiring synchronization to the digital trigger signal.
The digital trigger signal is available on connectors P1-P4 as illustrated in the following diagram.
P6 & P7
The internal PC board of the BNC enclosures (BNC16DI/SE only) contain 3 pin headers P6 and P7 which allows the user to modify
the function of BNC’s B15 and B16 from analog inputs to D/A outputs. Users should consult their DAS manual’s I/O connector pin
assignment section to verify that the data acquisition board being used has D/A output capability.
