Issue
Is it possible to use a new Xenta (v.3.84) with an old version of TAC Vista?
Environment
TAC Vista 5.x
TAC Xenta 302, TAC Xenta 301, TAC Xenta 401, TAC Xenta 28x
Cause
New orders for Xenta programmable controllers always come as the latest version. If there is a need to add or replace a device in an old installation will there be a problem?
Resolution
It is ok to use newer version of Xenta controllers in older TAC Vista installations. It is also okay to downgrade to an earlier 3.x version if desired.
