Does Session Manager support alias for VISA devices on remote systems?

[Mark_Ireton]

I have defined an alias for a device on a remote system.  The resource descriptor is "VISA::visa://s-tengscmqc-xp/ASRL2::INSTR".  I can open a Session Manager to the device using the resource descriptor, but not with the alias.  I'm using MAX 4.0.2.3002 and LV7.0.

Have you defined that alias on your target system in Max?

I have defined a VISA alias on my target machine, but that alias is not visible from my local machine.  I have attached a screen shot of MAX on my local machine showing the alias "SW1" that I have defined.  The problem is that Session Manager does not see this alias.  I can come up with a workaround, but that defeats the purpose of having an alias.

Hey Mark,

It is possible to specify an alias for a remote VISA session, however, it cannot be done directly from MAX.  There is an NISessionMgr.ini that is located at C:\VXIPNP\WinNT.  This is the ini file where Session Manager reads all of its logical names and aliases.  It is possible to specify a VISA Logical Name here.  For example in my ini file I put Serial2 = "visa://compname/ASRL1::INSTR" underneath [VISA Logical Names].  I was then able to access that remote VISA resource with just "Serial2".  There is a little more explanation inside of the ini file itself as well.  Let us know if this doesn't work.  Have a good one!
