Installation
Overview
To install and set up the CD 800, follow these basic steps:
1 Turn all of the equipment off. Make sure that the
video sources (composite and/or S-video device), the
CD 800, the output device (projector or monitor) and
contact closure control device are turned off and
disconnected from the power source.
2 Mount the CD 800. See “Mounting the CD 800”
below.
3 Attach the cables. See “Cabling” on page 2-7 or, if
you are connecting the CD 800 to a system switcher
in video loopback mode, see “Cabling for video
loopback” on page 2-8.
4 Connect power cords and turn on the devices in the
following order: output device, contact closure
controller, CD 800, and input devices.
5 Select an input from the front panel buttons or the
contact closure controller.
6 The image should appear. If it does not, ensure that
all devices are plugged in and receiving power.
Check the cabling and make adjustments as needed.
Select a different input to check for an image. Refer
to “Troubleshooting” in this chapter.
Mounting the CD 800
The CD 800 is one unit (1U) high and one-half unit wide. It
can be used as a freestanding unit or installed on a 1U
universal rack shelf (Extron part #60-190-01).
Follow these steps to install the CD 800 on a rack shelf:
1. Remove rubber feet from the bottom of the CD 800.
2. Place the CD 800 on the rack shelf. Align the front of
the CD 800 with the front of the shelf, and align the
threaded holes on the bottom of the decoder with the
holes in the rack shelf.
