Daktronics DF-12xx - Manual (Page 15)

Introduction 1-5
The DataMaster model numbers are described as follows: DF-102X-HH-C
1.4 Component Identification
The following list includes some of the more commonly used terms when
referring to these displays. Because Daktronics occasionally alters standard design
to meet customer needs, the actual display design may vary slightly from the
illustrations below.
This is only a brief overview. Refer to Section 4 for additional information on
maintaining the various display components.
Client: The client display contains a client driver that receives signal from the
“host” driver on the Signal IN terminals. These drivers can re-drive signal to other
client drivers.
DataMaster Controller (DM100): The handheld keyboard-like device used to set
the time, date, hold times, dimming etc. on the Gas Price display. See Section 5 for
more information on the DataMaster controller.
Display Address: The display address is an identification number assigned to each
driver in a network. The address is set using an 8-position binary switch on the
driver board. For single-line signs such as a Time & Temp display, the address will
typically be “1”. For Gas Price displays, the top display is often set to address “1”
and the others are set to “2”, “3” etc. The address will be displayed each time the
display powers up.
Digit Circuit Board: The LEDs are mounted to a circuit board, which mounts to the
back of a digit panel. Problems with individual digits, segments or LEDs may
require accessing or replacing this board.
Host/Primary: The host display contains the host driver which relays signal directly
from the DataMaster controller on its Signal IN terminals. It is the only driver
connected to the temperature/light sensor. The Signal OUT terminals are used to
connect to the client driver. The host driver is selected by inserting the protocol 4-
plug into the protocol jack.
LED (light emitting diode): LEDs are high-intensity, low-energy lighting units.
