Serial comunication Yokogawa WT1030M

[Misha4200]

Hi,

please can i ask you where i have problem in VI? I trying send *IDN command via VISA in labview but VI return to me timeout error.

I have Yokogawa WT1030M device. Everything is functional in NI MAX, but not in VI. So it is important set IO protocol to String 488.2. I set this parameter via property node and serial parameters via Serial Com sub VI. All parameters that i set is correct but VI return me timeout.

I was try drivers for this device (all version), but this drivers are for GPIB not for RS - 232.

Thank you for help.

 

Best regards Michael.

What is the display mode of the string constant containing the *IDN command? Is it really switched to "\-code" display?

(When you attach VIs it would help to downconvert them to LV2019 to reach a broader audience!)

How many different Yokogawa devices do you have in use with all your other threads?

I use 488.2 mode in device (not normal and more). I've been dealing with communication issues with two Yokogawa devices. These two issues have already been resolved.

You can use the driver also for RS-232 !!

The VISA resource control is somewhat hidden. There you can also select a COM port

I used special string constant for command. Like this:
