Electrical Installation 2-5
If using the DataMaster handheld controller at an indoor location, only the two, 22
AWG, signal wires (white and green) will need to be connected to the j-box. A wall
pack transformer, plugs into the indoor j-box, and provides power to the DataMaster
controller. The distance from the indoor j-box to the host driver can up to 2000 ft.

A radio controlled display uses the DataMaster controller inside connected to a j-
box. The j-box is then wired to a server radio attached to the building. A second
radio, called the client is connected to the Gas Price display. The DataMaster hand-
held controller and server radio receive their power from the j-box. A wall pack
transformer powers the j-box. The client radio receives its power from the display.
The display layout is shown in Figure 4
and Drawing A-199834.
