MUXM Functionality
If the string "DisMuxCheck" appears in the driver option string, the IVI check for connecting COM to multiple channels
is disabled, this allows MUXM cards to connect multiple channels to single COM.
Configurable Cards
MUX1 card is a mux(m) card that consists of many "small" muxes connected by interconnecting switches.
Any card with a 616/617A like structure can be used:
x subunits of muxes
x+1 isolators for those muxes
x+2 interconnecting switches between muxes
In INI file, configurable = 1 or configurable = MUX_616 line.
Config line in INI file must be real card's mapping of muxes e.g. 18(3x1)
It is possible to add more subunits to this using "+"
e.g. 18(3x1)+(20) is 616/617A type configurable card with 18(3x1) muxes, 2 special subunits for
configuration and after that there is (20) subunit.
Configuration of muxes is made using driver option string:
If driver option string contains token "config:x.x.x.x.x;", "x.x.x.x.x" defines configuration. If there is no such
configuration, the card initilizes so that all muxes work independently (no interconnection switch is closed).
Format and meaning of configuration line is this:
ViString optionString = "Simulate=0,RangeCheck=1,QueryInstrStatus=0,Cache=1,DriverSetup=Model:40-617A-
021;config:2.3.1.6;"
This would mean:
Connect first 2 muxes.
Connect muxes 3-4-5.
Leave mux 6 alone.
Connect muxes 7-12.
Note that there MUST be 12 muxes for configuration.
Assuming muxes are (3x1), this would create the following configuration:
(6x1)+(9x1)+(3x1)+(18x1)
