four relays in the
SmartLink
TM
that
control different
components:
• Relay 1 - ISP
equipment
• Relay 2 - DMP-

1.5 Terms Used in this Manual
Lanyard Attachment Ring: a ring found on the back of each module and on the display doors
that attaches to a lanyard and prevents the module from falling.
Latch Release: releases the latches that hold the module firmly in the display. There are two per
module, one near the top of the module and one near the bottom of the module.
Light Emitting Diode (LED): low-energy, high-intensity lighting unit.
Line Filter: removes electromagnetic noise that might interfere with local communication
channels from the power system.
Module: consists of a display board with LEDs, a driver board or logic card, housing, a module
latch assembly, and a louver. Each module is individually removable from either the front or
back of the display. Module part numbers vary by pixel pitch.
ProLink Router (PLR): the PLR takes data in and then routes that data to other areas in the sign.
There is typically one PLR per display section.
Power Supply: a device that converts AC line voltage from the panel board to low DC voltage
for driver boards. In the 4200 series, one power supply powers two modules, one controller, or a
ProLink Router (PLR).
Serial Advanced Technology Attachment (SATA) Cable: allows high speed signal from flow
from device to device. In digital billboards, they run signal from module to module and from the
PLR to the modules.
Termination Block: an electrical connection point, usually used to connect internal power and
signal wires of the same type coming into the display from an external source.
