You should refer to to the Programmer’s Guide section 3.2, Device Initialization, for a detailed 
explanation on the initialization procedure. 
This function is almost never needed, except if you want to dynamically redefine MultiInstruments with the 
aid of the function 
AcqrsD1_multiInstrDefine. If the function executes successfully, the instrumentID of 
the previously defined MultiInstruments cannot be used anymore. You must either have remembered the 
instrumentID of the single instruments that made up the MultiInstruments, or you must reestablish all 
instrumentIDs of all digitizers by reinitializing with the code shown in the Programmer’s Guide section 
3.2.1, Identification by Order Found.
