Sync Source 3 - Panasonic DBS-2.3-400 Programming Manual

Chapter 1. System Programming (FF1)

Sync Source 3

Software Version: CPC-B Version 4.0 or higher
Address: FF1 8# 4# 1# 4# (0-3)#
Description
Determines the source of clocking for the third sync source, which is used if
both the first and second sources fail.
If the third sync source is used, the DBS system will attempt to switch back to
the first source based on the value set for the Network Re-Sync Timer (see
FF1 8# 4# 2# 1# 0-25#).
In most cases, a system with one T1 has the third sync source set to "0"
(None). Systems with two T1s normally have the third sync source set to "3"
(Free run).
NOTE: One of the three sync sources should be set to "3" (Free run), so that
the T1 can provide its own clocking if the network clock fails.
See the Sync Source 1 address for an introduction to T1 clocking, and a list
of typical sync source settings in single-cabinet and double-cabinet systems.
Programming
Notes
Restriction on Duplicate Sync Settings. "Free run" is the only setting that
can be entered for more than one sync source.
Power-Cycling Requirement. For changes to this parameter to take effect,
the system must be turned off, then back on.
