A typical control setup for parking garages will be one in which the signs are
controlled remotely from a booth or office in the facility. Signal cabling is similar to
wired, base-of-sign control, except that the controller requires a wall pack
transformer. The transformer plugs into both the hand-held controller and into a
120VAC outlet. The DataMaster controller also connects to a junction box to send
signal to the display, but the j-box will be located within the booth or office. The
operator then changes the display by entering current parking information and
operating instructions on the keypad of the DataMaster controller. For complete
details on sign operation, refer to Section 5.

A display, or set of displays, can be programmed using a current loop signal from a
signal converter. The signal into the display can be sent directly from the computer,
through the signal converter, and then into the display, or the signal can be extended
through the use of two signal converters. The following sections will explain the two
different communication methods.
