Issue
In TAC Menta, under Device Specification, it is not possible to define the actual System Version or Hardware version of your TAC Xenta device.
Environment
TAC Menta Version 5.1.5
TAC Xenta 280/300/401 Version 3.80, 3.84
Cause
When a new System Program for TAC Xenta devices is released, TAC Menta is not always updated with the latest TAC Xenta version number.
Resolution
Until the correct TAC Xenta System Version number are available in the TAC Menta, you could use the closest lower version number.
