7.1 Control Equipment Overview
ISP Enclosure
The ISP enclosure contains all
of the necessary equipment for
the display to communicate
over the Internet and schedule
content.
Figure 15 shows the
equipment and the equipment
location within the ISP
enclosure.
DMP-8065
The Digital Media Processor
(DMP) receives the content
from the Internet, sends it to
the PLRs within the display
and to the modules. All of the
connections for the DMP are
located on the bottom of the
unit. The DMP is a field replaceable unit. Refer to
Figure 17.
Opening the ISP Enclosure
To access ISP box components:
1. Access the ISP enclosure by opening the rear access door with the control equipment
label.
2. Using a flathead screwdriver, turn the two three-quarter turn latches counterclockwise.
3. For easier access to ISP components, the ISP enclosure door can be lifted off the hinges.
Connecting a Laptop
Sometime it is necessary to connect a laptop to the display for service. For displays without
shared internet, locate the red cross-over cable coming from out of the network switch or the
router. For displays with shared internet, disconnect the webcam from port 4 of the network
switch and connect a Cat-5 cable from port 4 to the laptop.
