Table D-4: Gain Codes for the PCI-1712/1712L
D.6 MUX Control Write BASE+4
Table D-5: Register for multiplexer control
STR3 ~ STR0 Start Scan Channel Number
STP3 ~ STP0 Stop Scan Channel Number
When you set the gain code of analog input channel n, you should set
the MUX start & stop channel number to channel n to prevent any
unexpected errors. In fact, Write BASE+4 bit 3 to 0, STR3 ~ STR0, act
as a pointer to the address of channel n in the SRAM when you
program the A/D channel setting (refer to Section D.5).
Note:
✎ We recommend that you set the same start and stop channel when
writing to the register Write BASE+2. Otherwise, if the A/D trigger
source is on, the multiplexer will continuously scan between channels
and the range settings may be set to an unexpected channel. Make sure
the A/D trigger source is turned off to avoid this kind of error.
