the stop channel and then repeat. The following examples show the scan sequences of the MUXs (all channels are set as
Example 1 | If the start scan input channel is AI3 and the stop |
scan input channel is AI7, then the scan sequence is AI3, AI4, AI5, | |
AI6, AI7, AI3, AI4, AI5, AI6, AI7, AI3, AI4… | |
Example 2 | If the start scan channel is AI13 and the stop |
scan channel is AI2, then the scan sequence is AI13, AI14, AI15, AI0, AI1, AI2, AI13, AI14, AI15, AI0, AI1, AI2, AI13, AI14…
The scan logic of the
14). In each pair of differential channels, the even channel is the positive end and the odd one is the negative end.
For example, if channel 0 is set as differential, then channel 0 and channel 1 are combined into one channel and refer to the gain code and B/U of channel 0 (the channel 1 values are unavailable). By the same rule, if channel 2 is set as differential, then channel 2 and channel 3 are combined into one channel, and refer to the gain code and B/U of channel 2 (the channel 3 values are unavailable). The following examples show the scan sequences in differential mode.
Example 3 Suppose that the start scan input channel is AI14 and the stop scan input channel is AI3. If AI14 is differential, AI0 and AI1 are
Example 4 Suppose that the start scan channel is AI11 and the stop scan channel is AI15. If AI11 is
