I am working with a Keithley 3706-S switcher which can be configures using a LUA code sent via Test Script Builder (TSB). LUA code for my application is simply one single line:

channel.exclusiveclose('1003')

Now the above instrument is interfaced over the USB port. I would like to know how could I do the same using Matlab

Wait, I thought the interface to that device was via TCP ??

Well if it is USB, then use serial() to allocate the virtual USB serial port to an object, use set() to configure the speed and so on, fopen() the serial object, and fwrite() or fprintf() the string to the serial object.

Be sure to find out exactly what line terminator is required and watch out because fprintf() automatically adds the LineTerminator configured for the serial object if you use the call fprintf(object,string) instead of using fprintf(object,format,string)
