Electrical Installation 3-7
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 be up to 2000 ft.
Refer to
Figure 8 and Drawing A-175342 for system layout and signal connections.

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 9
and Drawing A-199834.
1. Using the DB9M to DB9F serial cable, connect from the DataMaster
controller to the J-box, at the “DB9 Male, DataMaster 100 connect” jack.
2. Using an 18-AWG, 6-conductor, shielded cable, (W-1370) connect from
the j-box jack labeled “RS422 to Radio or 422 Device” to the TB1 jack
on the Server radio, mounted to the building. See
Figure 10 and the table
below for cable connections from the j-box to the radio.
3. Plug the wall pack transformer into the j-box and then into a 120V
grounded outlet.
4. Mount the Client radio on the display or display pole, and within 25 feet
of the display.
5. Plug the quick connect cable from the client radio into the 6-pin quick
connect jack on the side of the Gas price display.
