Satellite System Setup

For satellite system operation, specific setup procedures are

required, at each satellite site, before any REMOTE functions

can be accessed. These procedures vary according to the type

of site interconnections. Each site may be either a Source Site,

a Receiving Site, or both, depending on the network video

connections (uni-directional or bi-directional).

Source Site - a satellite network site which provides video

trunk outputs to other sites.

Receiving Site - a satellite network site which receives

video trunk inputs from other sites.

Typical Source and Receiving Site connections are illustrated

on pages A-14 and A-15 of the Appendix.

IDENTIFY EACH SATELLITE SITE

Assign a separate Site Number, 1 to 16, to each individual

site in a satellite network. The Site Number is required for

addressing purposes when commands and data are

transmitted across the RS-232 interfaces between sites.

At every site, use the System Options menu, page 4-16, to

set the Site Number of the LOCAL Site.

IDENTIFY RS-232 DATA LINKS BETWEEN SITES

At every site, identify the AD1024 CPU RS-232 ports which

are used for Data Communications links to other sites in the

satellite network.

Use the Data Communication menu, page 4-34, to identify

the LOCAL RS-232 connections to each REMOTE Site.

This sets the specified LOCAL port(s) to SATELLITE use,

with default RS-232 parameters (1200 Baud, No Parity, 8

Data bits, 1 Stop bit).

Note: Use the Ports menu, page 4-22, to change default

RS-232 parameters as desired for each LOCAL port.

IDENTIFY VIDEO TRUNK ROUTING BETWEEN SITES

At a Receiving Site only, identify all individual video trunk

inputs from each REMOTE Site.

Use the Video Assignments menu, page 4-35, to define the

REMOTE video routing (video trunk inputs) at each

LOCAL site. This setup provides the proper callups when

REMOTE cameras are called by the LOCAL system.

In addition, use the Camera Title menu, page 4-21, to

program a REMOTE site title for each video trunk input.

This title is displayed in the REMOTE On-Screen display,

page 2-4 when that site is called from a keyboard.

If the AD1024 system is equipped with Video Loss Detector

modules, each video trunk input should also be set for

SYNC ONLY loss detection via the Camera Title menu.

SPECIFY ACCESS RESTRICTIONS

After identifying the video trunk routing for each site, access

restrictions should be placed on specific monitor and camera

callups at each site. These restrictions prevent interference

with satellite network operations.

Access restrictions are placed at each Source Site providing

video trunk outputs to other sites and at each Receiving Site

receiving video trunk inputs from other sites.

Access Restrictions at Source Site

At the Source Site, each video trunk output provides video

in response to REMOTE site requests only. Access to

each such video trunk output must be restricted at the

Source Site to prevent inadvertent LOCAL callup of

cameras to that video trunk output.

Use the Keyboard/Monitor Access menu, page 4-25, to

set user access to these trunk monitor outputs to “N”

(access denied) for all LOCAL keyboards.

Access Restrictions at Receiving Site

At the Receiving Site, each trunk camera input provides

REMOTE video input only. Access to each such camera

trunk input should be restricted at the Receiving Site to

prevent inadvertent LOCAL attempts to call or control

that video trunk input.

Use the Keyboard/Camera View Access menu, page 4-

26, to set user access to these trunk camera inputs to “N”

(access denied) for LOCAL keyboards.

Note: Certain keyboards (e.g., supervisor or maintenance

users) may need access to confirm availability of video

trunk camera inputs. For these keyboards, set the

Keyboard/Camera access to “Y”, allowed.

Use the Keyboard/Remote Site Access menu, page 4-30,

to set any desired restrictions for LOCAL keyboard access

to REMOTE Sites.

In addition, restrictions for individual LOCAL keyboard,

monitor, and camera access are set at the users option via the

access menus, pages 4-24 to 4-30.

Note: Since AD1024 Satellite System networks contain many

varied interconnections, ensure that all connections between

sites are verified before starting the above procedures.

Tables are provided in the Appendix, page A-13, to record all

interconnecting links to the LOCAL Site. Record all

interconnections at each site, and keep in a safe place.
