Signal Routing
Figure 12 shows how signal is routed through the display.
1. Signal enters the display from the external signal enclosure through the knockouts in
the back of the display (1).
2. Signal travels from the knockouts to the J10 and J11 fiber jacks on to the PLR (2a). The
light sensor is connected to J8 on the PLR (2b).
3. From SATA A on the PLR, signal goes to the first module (3a) and travels from module
to module via SATA cables (3b), finally returning to the PLR to SATA B (3c).
4. Signal leaves the PLR from Fiber B and travels to the Output Fiber Quick Connect (4)
or to the second PLR Fiber A.
5. Signal from the primary display face Output Fiber Quick Connect travels to the mirror
face (5) to jack J32.
PLR Diagnostics
The ProLink Router (PLR), receives signal from the display player, which transfers it on
to the modules through SATA cables. Vanguard
®
VC6 displays are equipped with a
redundant signal path, meaning two SATA cables are connected to each module. If one
of the two SATA cables fail, the module continues to receive data from the other SATA
cable and the display continues functioning normally.When put into self-test mode, the
PLR tests for correct operation and displays pass/fail status on the 7-segment display.
