This section provides information on the setting up the signal connection between
the DM-100 and DataMaster Gasoline Price displays.

The DataMaster displays may be controlled from a location inside a building, or
from the base of the display, depending on customer preference. Drawing A-164988
and the subsections that follow provide greater detail on both installations using
signal wire.
Wire Control from the Base of the Sign
This control option, illustrated in
Figure 13, permits operation of the
sign from the base of the display. The
controller is connected to an outdoor
junction box mounted on the display
pole, which routes the signal to the
sign through one 2-pair cable, 22
AWG. Cable is in conduit where
required.
This control option does not require
the controller to be connected to a
power outlet. In this configuration,
the DataMaster 100 uses the sign as a
power source.
To operate the DataMaster display
using this setup, connect the 9-pin to
9-pin cable from the DataMaster
controller to the 9-pin j-box mounted
on the display pole.
Wire Control from a Building Location
This control option, illustrated in Figure 14, permits operation of the sign from an
indoor control location. The hand-held controller is connected to an indoor junction
box (j-box), which routes the signal to the sign through one 2-pair cable, 22 AWG.
Cable is in conduit where required.
