INSTALLATION
Mounting
Bays are manufactured for standard 19-inch rack mounting and
have a rack height of 10 1/2-inches, or one rack wide by 6
racks high. Bays must be installed with a minimum of 1 3/4-
inch clearance between each bay (one rack unit). It is the
responsibility of the installer to insure proper airflow around
the bays to provide adequate ventilation.
In multiple bay configurations, identify the various bays
carefully before mounting. In all multiple bay systems, place
the video inputs near the top of the racks.
Power Sources
System model AD1024R is configured for use with a 120VAC,
50/60 Hz primary power source. Model ADS1024RX is
configured for a 230VAC, 50/60 Hz primary power source.
All 120 V units are supplied with a pendant, 3-wire cord and
plug for mating to the primary source outlet. All 230 V units
are supplied with a Euro style IEC type inlet. A suitable
detachable cord should be connected between the IEC 320
inlet and the power source. The cord should conform to all
national and local use code requirements.
DO NOT PHYSICALLY CONNECT
EQUIPMENT TO THE POWER SOURCE UNTIL
"POWER UP"
PROCEDURES HAVE BEEN COMPLETED.
Read the section on POWERING UP (page 19) before
connecting the system to the power source, and check the
various System Configurations shown in the Appendix.
Connections
All system connections are made on the rear panels of the
system bays. Connections for several typical System
Configurations are described in pages 20 through 47. See the
Appendix for illustrations of various system connections.
Note: Make all internal jumper switch settings on the
modules before system connections are started (see SETUP,
pages 12 - 18). Be certain that all connections are properly
completed before applying power.
All video connections should be made using a good grade, 75-
ohm, RG-59U video cable (i.e., Belden 8241 or equivalent)
with BNC connectors.
All video outputs must be terminated in 75 ohms at the last
unit in the run. Set the intermediate units to HiZ. If the video
run is not terminated, or if it is double terminated, the resulting
picture will be of poor quality. If the run is not terminated a
brighter picture than desired will be displayed. Conversely, if
the run is double terminated, a darker picture than desired will
be displayed.
Each installation should be made in a planned and orderly
manner. The operation of each piece of equipment should be
confirmed as early as possible during the installation
procedure. It is much easier to remove a few temporary
terminations, or connections, after a confirmation check than it
is to disconnect and re-wire a large number of "permanent"
connections.
To facilitate maintenance and assist in service, all connecting
cables should be identified with source/destination numbers.
