I am trying to connect a Mettler- Toledo JL- 6001 balance to my computer as an input for a LabView Program through a RS-232 to USB line.
In MAX, I sometimes (but not always) get the error message that "The resource is working properly but VISA cannot currently access it".
Under the General tab for this port I get the message" VISA returned this device when finding resources, and MAX was able to use VISA to parse the resource name. The resource was busy, so MAX could not successfully open a VISA session to the device."
In LabView, the program runs but I get all zeros as the output which is definitely not correct.
I have tried disabling and then enabling the port. I have tried making sure no other program is using the device, and restarting the computer.
I am not sure I have the correct driver installed for this scale (MTT driver), (they make a lot of balances and a few drivers and wasn't sure which one to use). I don't know if this makes a difference in MAX.
Any tips for how to get the balance and MAX to communicate? Also I know almost nothing about digital/serial data transfer so a very dumbed down answer would be greatly appreciated.
Thanks in advance,
Joanna R Murphy
