tbkSetScan
DLL Function int tbkSetScan(uint *chans, uchar *gains, uchar polarities, uint count);
C tbkSetScan(unsigned *chans, unsigned char *gains, unsigned char *polarity,
unsigned count);
QuickBASIC BtbkSetScan% (chans%, gains%, polarity%, ByVal count%)
Visual Basic VBtbkSetScan% (chans%(), gains%(), polarity%(), count%)
Turbo Pascal tbkSetScan( chans:WordP; gains:ByteP; polarity:ByteP; count:word ):integer;
Parameters
uint *chans An array of up to 512 channel numbers (see table at end of chapter for valid values)
uchar *gains An array of up to 512 gain values (see table at end of chapter for valid values)
uchar polarities An array of up to 512 polarity values. Zero value causes TempBook/66 to select Unipolar mode. Non-
zero values causes Bipolar mode.
uint count The number of values in the chans and gains arrays
Valid values: 1 - 512
Returns TerrNotCapable - No high speed digital
TerrInvGain - Invalid gain
TerrInvChan - Invalid channel
TerrNoError - No error

Program References
tbkSetScan configures a scan sequence consisting of multiple channels, polarities and
corresponding gains. As many as 512 entries can be made in the scan configuration. Any analog
input channel at any gain can be included in the scan. Channels can be entered multiple times at the
same or different gain. The high-speed digital I/O port can also be included although its gain value
will be ignored.
