Issue
The TAC Operator Panel (OP) will not show the controllers on the network and only displays "No Answer."
Product Line
TAC Vista
Environment
- Classic Vista networks
- LNS Vista networks
Cause
Programmable Xenta controllers only support 2 Operator Panels per device.
Resolution
Each Xenta controller can only have two Operator Panels connected to it at once. To have more operator panels, ensure that you have at least one programmable Xenta controller for every two Operator Panels.
See "No Answer" on an OP when connecting to a Xenta 280/300/400 for some other situations that can cause this issue as well.
