16 Col. MASC Driver Specifications ..................... Drawing A-184475
In sign systems with multiple displays, one driver at each sign installation is
designated as the “host driver.” This driver receives its signal directly from the
controller on the Signal In terminals, and it is the only driver that is connected to the
photo/temp sensor. The Signal Out terminals are used to connect to “client drivers.”
Refer to Drawing A-185236 for an illustration of the client/host driver display
setups.
Select the host driver by inserting the Protocol 4 plug into the 5-pin protocol jack
(J20.) Refer to Drawing A-184475.
The 12 V DC terminals connected to the host driver (see “Signal Connections” in
Figure 4) run to the controller junction box. This output is used to power the
DataMaster 100 controller.
All other drivers in the display system are client drivers. These drivers receive signal
from the host driver on the Signal In terminals and can re-drive this signal to other
“client drivers” on the Signal Out terminals.
The address of each driver is set using the address jack (J19), and the address setting
is based on that driver's position in the sign or display system. If a single-line sign is
used, the address will typically be address “1.” This is the default address plug that is
shipped with each display. In a multiple-sign display, the address plug determines
which line of information is shown on the drivers' digits. The address plug for each
line is included in the address plug kit, if applicable.
2.4 Modem Installation
Reference Drawing:
Modem Installation, MASC Driver Enclosure..................... Drawing A-194873
In most instances, DataMaster Lottery displays will be controlled by modem.
Typically, modems and cabling will be factory-installed and ready to operate.
In the event that a modem must be field installed, refer to the 16-Col Driver detail on
Drawing A-194873, and follow these steps:
1. Make sure the power to the display is off.
2. The modem mounts on four standoffs to the left of the driver. Position the
card on the standoffs and secure it with the hardware provided.Plug in the
RJ-45 end of the modem cable to the J6 connector as shown in Figure 5.
Plug the RJ-11 end of the cable into the J24 jack on the driver.
3. Plug in the 12-volt power source, P3, to the J3 connector on the modem
card.
