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 sign. All the power and signal wiring
terminates at the driver enclosure. The DataMaster hand-held controller receives its
power from the display. The display layout is shown in Drawing A-177150.
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 near the display.
2. Route a 6-conductor, 22 AWG, shielded cable through conduit from the j-
box to the driver enclosure in the host display. (Distance limit from the j-
box to the display is 50 ft.)
3. Connect the signal/power cable from the j-box to the driver enclosure as
shown in Figure 6 and listed in the table. Refer to Drawings A-164988 and
A-184918 for additional information.
4. Using a DB9M to DB9F serial cable, plug the DataMaster controller into
the j-box, connected to the host display driver enclosure.
