Replace an old Xenta 301 system version 1 with a new controller

[Product_Support]

Issue

You need to replace a faulty Xenta 301 controller. However, the existing unit is running System Version 1, and the network comprises approximately 12 Xenta controllers on a Menta-only network using the .nwc and .ndb configuration tools.

Product Line

TAC Vista

Environment

TAC Xenta 300

Cause

New Xenta 301 controllers are shipped with System Version 3 by default. System Versions 1 and 3 are incompatible on the same network.

Resolution

To ensure compatibility, downgrade the new Xenta 301 controller to System Version 1.17 before installation.

Steps to Downgrade and Replace:

1. Download TAC Xenta 300 system program version 1.17
   • Use the Download Wizard as usual.
   • Important: When downgrading from Version 3 to Version 1, do NOT retain the old application in the Download Wizard.
   • Select "Clear Application" during the process.

2. Manually Download the Menta Application and Network Configuration

   • Use a serial cable to perform the manual download.

   • Apply the appropriate TAC Menta versions for your network setup.

Additional Notes

• Mixing different system versions on the same network can lead to unpredictable behavior and communication issues.
• Always verify the version compatibility before deploying new hardware.
