Multifunction I/0 6353 not connecting

[jolykj]

I have used a Multifunction I/0 6353 for some month now, and suddenly it has stop connecting to my PC, it has it own power sauce, acces to USB, grounded and have been working perfectly before.

This week the 6353 has suddenly decided not to connect to my pc, no matter which order I turn the PC and 6353 on or connect the USB.

I have been using it for now to get the reading from a Piezo Vacuum Transducer (https://www.mks.com/p/902B-11024), using the AL 0 and AL 8 pin, without any problems. I use LabVIEW to get the readings.

Have I somehow broken the 6353 or is there something I could have been missing?

Hello, I hope the below information helps, and your device is not broken, as this has occurred so out of the blue, it is likely to be as simple as a new cable or updating software:

Potential causes include:

1. Hardware failure - The USB-6353 itself may have developed an internal fault
2. Power supply issues - Inadequate or unstable power to the device
3. USB connectivity problems - Damaged cable, port issues, or connectivity failures
4. Driver corruption - NI-DAQmx drivers may be corrupted or incompatible
5. System changes - Recent Windows updates, BIOS changes, or other system modifications

Possible Solutions:

Software reset:

• Reset the NI-MAX configuration: Open NI-MAX, select Tools → Reset Configuration Data, and confirm.
• After the reset, restart your computer and reconnect the device.
• Note: This will reset all device configurations and tasks.

Driver reinstallation:

• Uninstall NI-DAQmx software from Control Panel.
• Download the latest compatible version.
• Reinstall NI-DAQmx and restart your computer.
• Reconnect the device.

Some longshots to try before giving up:

• Check Device Manager for any unknown devices or devices with warnings
• Verify Windows power management isn't turning off USB controllers (in Power Options)
• If available, check the device on a different system to determine if it's a hardware failure

If the above solutions don't get you anywhere, it is probably safe to safe your device is broken. If still under warranty I imagine tech support will solve your problem for you.

Thanks,
