Signal Routing
shows how signal is routed through the display.
1�
Signal enters the display from the external signal enclosure through the signal input
quick-connect jacks (1).
2�
Signal travels from the J32 signal input jack through an Ethernet Cat5e cable to the
J32 Ethernet jack on the controller (2a).
•
The J33 auxiliary input jack and jack J31, for optional external temperature sensor,
connect to breakout harness to jack J36 on the controller.
•
The light sensor is connected to the breakout harness to the J36 jack on the
Controller (2b).
3�
In single-face displays, signal
travels from the Controller SATA
A jack to SATA A on the first
Module (3a) and travels from
module to module via SATA
cables (3b). Refer to
Signal returns to the Controller
SATA B jack (3c).
4�
In 2V displays, signal from the
primary display face RJ45
Quick Connect travels from the
Primary Out jack to the mirror
face (4) to the Mirror In jack.
5�
Signal returns from the mirror display via the Mirror Out jack to the Primary In jack
on the primary display and finally returns to the Controller SATA B jack (5). Refer to
.
Note:
One-high displays must be located less than 20' apart to accommodate
signal redundancy between primary and mirror displays.
