VISA Devices with same serial number and vendor ID cannot work together (0xBFFF003A)

[sqrt(-1)]

Hi all,

I have to acquire data from two power meters YOKOGAWA using VISA driver (USB connection).

They work fine if used alone, but they don't work when are used toghether. In particular, when I connect and turn on both of them, NI MAX shows me the following error:

0xBFFF003A (VI_ERROR_INV_SETUP)

viFindRsrc returned 0xBFFF003A (Unable to start operation because setup is invalid (due to attributes being set to an inconsistent state).)

Please make sure VISA is properly installed on this system.

Possible causes for this error:
1. More than one Passport may be attempting to claim the same resource.  You can try disabling Passports to figure out which Passport is causing the error.
2. You have connected multiple unconfigured plug-and-play devices that have the same resource name. For example, the vendor ID and serial number may be the same.

Actually, according to MAX, the two the power meters have the same serial number and the same vendor ID; so, this seems to be the reason why they don't work together.

Can someone help me?

Thanks all

Hi,

It would if you tell me which Power Meter  (WT) you are using.

I'm using:

WT310 and WT330

These instruments are not IVI compatible. But I would expect that MAX will see two different instruments because they are connected to different interfaces. 

The instruments have the same USB ID numbers but not the same serial number. That something different.

I will have a look if can can get a hold of two of these instruments.

OK, thank you

I have a WT310 and a WT330. The image shows what I see in MAX.

Can you show me what you see in MAX for each instrument ?

Here is what I see when I connect WT310, WT330 and both.

Strange that the last figure is the same for both. I will check this.

My versions:

MAX and VISA are 15.

WT version for both is 1.04

How can I know WT version?

You see the FW version at startup at channel C.
