A direct-controlled display uses a current loop connection from the J box at the base of the display to the
driver enclosure in the display. All the power and signal wiring terminates at the driver enclosure. The
DataMaster controller receives its power from the display. The display layout is shown in Drawing A-164988.
Note:
The cable from the J box to the display needs to be routed through conduit or the display pole to protect
it from weather and vandalism.
1.
Mount the J box at the display.
2.
Select the host driver by inserting the Protocol-4 plug into the five-pin protocol jack (J20).
3.
Route a six-conductor, 18 AWG, shielded signal cable through conduit from the J box to the driver
enclosure in the host display. Fifty feet (15.2 m) of signal wire is provided.
4.
Connect the signal wire from the J box to the driver enclosure as shown in
and listed in the
table. Refer to Drawings A-938369 and A-938300 for additional information.
