Kalypso Emergency Bypass Option Instruction Manual 5
Emergency Bypass Option
Introduction
Note The Emergency Bypass option operates with Kalypso Classic, Kalypso Duo,
and Kalypso HD systems running in SD operating mode. This option does not
operate with Kalypso HD systems running in HD operating mode.
The Emergency Bypass system provides basic switching capability should
a component in the Kalypso system fail or lose power. The Emergency
Bypass option uses an external router to perform the actual source selec-
tions. Operator control is provided by the Local Aux panel. If the Kalypso
system Main panel and/or the Video Processor frame fails, the Local Aux
subpanel, Emergency Bypass frame, and facility router can still provide
basic switching and keying capability. Note that the Emergency Bypass
option and the Kalypso system Router Interface are completely separate
features that do not interact with one another.
During normal operation, the Video Processor frame sends emergency
bypass configuration information to the Local Aux panel, where it is stored.
The Local Aux bus uses this copy of the information for controlling the
Emergency Bypass frame should the Video Processor frame fail.
Note On 4-M/E Kalypso systems, the Emergency Bypass option operates with
Local Aux panel part number 610-0935-00.The previous version
(614098300) is not compatible. On 2-M/E Kalypso systems, the Emergency
Bypass option operates with Local Aux Processor Interface Board
671494502 and higher. If you do not have the correct revision of hardware,
