4-4 Control System Overview
Modem and Radio Control
A third "wired" method of relay information to the display is by using a dial-out
modem system and a telephone line. A modem junction box is required for this
operating system. Most DataMaster Lottery displays will be controlled by modem.
For basic information on installing a modem, refer to Section 2.4. The DataMaster
Modem Installation Manual, ED-13953, provides complete information on modem
systems, including cable routing and j-box installation.
Optional DataMaster bidirectional radio permits control of any DataMaster display
without the use of a direct-wired connection between the DataMaster 100 and the
display. Because radio is optional with DataMaster displays, the receivers and
transmitters must be field-installed.
For additional information for either of these options, please contact your Daktronics
account representative or service provider.
