Universal Library User's Guide Analog Input Boards - CIO-, PCI-, and PC104-DAS08 Series
67
Before using the cbAInScan() function or the AInScan() method for timed analog input with a CIO- or
PC104- series board, the output of counter 1 must be wired to the Interrupt input; if you have a CIO-DAS08
board revision 3 or higher, a jumper is provided on the board to accomplish this. An interrupt level must have
been selected in InstaCal and the CB.CFG file saved.
Triggering and gating
Polled digital input triggering (TTL) supported. Refer to "Trigger support" on page 29 for more information.
Use pin 25 as the trigger input.
Pacing analog output
Software pacing only
Digital Output
Since the channel settings and DOut bits share a register, attempting to change the digital output value during
an analog input scan may result in no change or unexpected values in digital output ports.
