Problem
TSC touch panel keeps going offline
Causes
While not a definitive list of every possible reason for touch panels going offline, the following factors can affect connectivity of TSC touch panels.
- Network switch configuration issues
- UCI assignment issues in the design
Solution | Workaround
The following are some things to check to help resolve TSC connectivity issues.
Network Switch Configuration
- "Green Ethernet" (Energy Efficient Ethernet) should be turned off on the network switch. When enabled, ports for Q-SYS peripherals may end up being turned off by the switch.
- Auto-speed negotiation can create problems on some switches. It is best to turn off auto-speed negotiation on ports related to touch panels and lock them at 100MB.
- In some instances, enabling Flow Control may also help, typically for the TSC-7 touch-panels.
UCI Assignment & Design
- Ensure that a UCI is assigned to the touch panel's Status/Control component in the design.
- Complex UCIs have been known to prevent some touch panels from loading their designs, or result in frequent resets of the panel. These UCI best practices may help:
- Replace any video preview windows on the UCI with the Media Display control released in Designer 9.2.1.
- Reduce the overall number of control elements in a UCI.
- Consolidate UCI Pages and Layers when possible to reduce their overall quantity.
- Reduce the resolution of image files included in a UCI to a resolution that closely matches the resolution as they would be shown on the touch panel.
- Set a UCI’s Swipe Disabled property to 'Yes' and Enable Button Swipe to 'No' if possible.
- Avoid having multiple UCI Layer Visibility Transitions happening at the same time.
- Reduce the number of active VU meters in a UCI to reduce the amount of data received by the TSC panel.
- Avoid using VU Meters using the Segmented Meter Type
