- Potential poor image quality. A single loss of sync it not likely to cause visual problems for a display, but if multiple losses of sync occur in a ProLink6 circuit, all modules associated with the nodes between the points of failure may go blank.
IDM / System Health Event(s)
- Loss Of Sync ProLink 6 diagnostics alert (port A or B) on PLR.
- Product Family: Billboards, Message Displays
- Product: System Health, IDM
- Component: PLR, DB-4000, DB-4200, DB-5000, DB-6000, DB-6400, GS6, GT6, GalaxyPro
- Control System:
The PLR receives ProLink6 data on two ports - A and B. A loss of sync on one port will cause the PLR to switch to the other port. While a loss of sync itself is a non-visual event, it may be caused by the reset or failure of a ProLink6 node (PLR or VIP-4060) directly connected to the PLR, and therefore may be an indirect indicator of a visual outage.
A persistent loss of sync on a ProLink6 circuit indicates that data redundancy has been lost. Another loss of sync on the same circuit will result in a visual outage affecting all nodes between the two points of failure.
- This event is created if the ProLink Router (PLR) detects that it is not receiving a ProLink6 signal on Port A or B, causing it to increment a counter.
- Look for events indicating that the ProLink6 node connected to Port A or B of the PLR experienced a reset or diagnostic failure, and use the display's webcam to determine if there are any visual issues occurring on the display.
- If no such events exist, inspect the fiber optic cable connection between the PLR and the ProLink6 node connected to ports of the PLR.
- Reseat or replace fiber between PLR and next device in the signal chain (PLR or VIP).
