UNCTION ARAMETERS
vi = contains a session handle to the instrument. This handle is obtained by the function and remains valid until the
session is closed.
channels[] = an input integer array containing a list of channel numbers for which the linear scaling coefficients will
be set. Valid input values: 0 to 47.
numberOfChannels = the size of the channels list. Valid input values: 1 to 48.
muxInValue = the input multiplexer source. Valid input values: 0 to 4

ESCRIPTION
This function sets the input multiplexer source. The muxInValue parameter can be set to the following values:
Decimal Hex
Value Value
0 0x00 VTEX1629_INPUTMUX_BRIDGE_TYPE_FULL
1 0x01 VTEX1629_INPUTMUX_BRIDGE_TYPE_HALF
2 0x02 VTEX1629_INPUTMUX_BRIDGE_TYPE_QUARTER
3 0x03 VTEX1629_INPUTMUX_BRIDGE_TYPE_CAL
4 0x04 VTEX1629_INPUTMUX_BRIDGE_TYPE_GND
NOTE This function provides a manual method that is normally only used for specialized cases like doing
voltage measurements in quarter bridge mode. The vtex1629_set_EU_conversion command is the
preferred way of setting up the input mux, completion resistors, and the EU conversion.
