Software Architecture Channel-List Entry Channel Synchronous Digital I/O Value 0 7 1 Description Sample channel 7 and output a value of 1 to the dynamic digital output channels. 1 5 1 Sample channel 5 and output a value of 1 to the dynamic digital output channels. 2 6 0 Sample channel 6 and output a value of 0 to the dynamic digital output channels. 3 4 0 Sample channel 4 and output a value of 0 to the dynamic digital output channels. In this case, when channel 7 is sampled, a value of 1 is output to the dynamic digital output channels. When channel 5 is sampled, a value of 1 is output to the dynamic digital output channels. When channels 6 and 4 are sampled, a value of 0 is output to the dynamic digital output channels. If your device had two dynamic digital output bits and a value of 1 is output (01 in binary format), a value of 1 is written to dynamic digital output bit 0 and a value of 0 is written to dynamic digital output bit 1. Similarly, if a value of 2 is output (10 in binary format), a value of 0 is written to dynamic digital output bit 0 and a value of 1 is written to dynamic digital output bit 1. 5 5 5 5 5 5 5 5 Note: If you are controlling sample-and-hold devices with these channels, you may need to program the first channel at the sample logic level and the following channels at the hold logic level; see your board/device driver documentation for details. 5 107
