Keyence LJ-G communicate as USB RAW device

[zheng2188]

Hello, everyone.

I have been trying to communicate Keyence LJ-G030 to Labview through USB connection. Currently, I have installed the driver from 'Driver Wizard' and after that I can see the Keyence on both Windows device manager as 'NI USB Devices' and on MAX as 'KEYENCE LJ-G(USB)'.

However, when i started the 'Visa Test Panel' on MAX and wrote command to it, I could not get any return data. The error is always:

“

Read Operation
Error

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

” 

I have tried many different commands, but none of them results in any return value.

Does anyone know what is problem?

Any kind of help will be appreciated.

Since you decided to create your own driver instead of the one that Keyence provides and in order to do that, you would need the details on the protocol from Keyence, i'm not sure why you have posted here. No one else knows those details and without those details, it is just silly to use the VISA wizard so you should go back to Keyence and ask for more help.
