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 selections. 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
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.
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,
contact Grass Valley Group Customer Service for an upgrade.

Emergency Bypass Frame
The 2 RU Emergency Bypass frame (Figure 2) fits a standard 19 in. (483
mm) equipment rack, and requires a 14 in. (356 mm) mounting depth.
Behind the front cover are ten slots for modules, plus one control slot and
two slots for power supplies.
CAUTION The Emergency Bypass frame front panel must remain in place during system
operation to provide proper cooling. If the panel is removed for an extended
period, modules can overheat and fail to operate correctly.
The forced-air system has a front cover that is equipped with three fans for
air circulation. The fan speed varies with the ambient frame temperature to
extend fan life and reduce noise when the frame is used in cooler configurations and environments. The fan speed control voltage is generated on
the Bypass Frame Monitor module and can be disabled so that the fan runs
at maximum speed only (see page 24).
The right rear of the frame (Figure 3) includes ten groups of ten connectors
(corresponding to the ten frame slots), which are used for input/output
functions for inserted modules. The standard Kalypso Emergency Bypass
option only uses two of these groups, typically slot 7 for the Relay Module
and slot 8 for the Keyer module.

The power/communication section at the left rear of the frame provides:
•RS-422 communications (the connector is labeled RS-232, but is RS-422
when the Bypass Frame Monitor module is installed),
•AC power plug connections, and
•SMPTE Alarm BNC (J101) for fault reporting (see below).
The Ethernet connector is not used with the Kalypso Emergency Bypass
option.
The J101 SMPTE Alarm connector retains the original 8900 system functionality when the Emergency Bypass version of the Frame Monitor
module is installed. Normal 8900 system faults (P/S failure, fan failure,
etc.) will trigger the alarm. Also the Bypass Keyer module triggers the
alarm upon some startup failures. The Bypass Relay module has no alarms.
See page 24 for more information.
Emergency Bypass Relay Module
The Bypass Relay module switches incoming video from normal to bypass
operation. The toggle switch must be in the center
remote activation of bypass operation. See page 27 for more information.
Emergency Bypass Keyer Module
The Bypass Keyer module keys up to two signals over incoming video, and
provides Program and Preview outputs. The keying can be set for shaped
or unshaped video (page 20). Also see page 25 for more information.

Emergency Bypass Frame Monitor Module
The Bypass Frame Monitor module provides system control, communications, and alarm reporting. See page 23 for more information.
Note
The Kalypso Emergency Bypass Frame Monitor module is not a standard
8900 Frame Monitor module. It is specifically designed for use with the
Kalypso Emergency Bypass system and RS-422 communications with the
Local Aux panel.
Frame Restrictions
•The Emergency Bypass frame hardware is designed to integrate closely
with the Kalypso system and is intended only for that purpose. Only
Emergency Bypass modules should be installed in the frame.
CAUTION Do not install any other types of 8900 series modules in the Emergency
Bypass frame.
•Browser based GUI control and monitoring normally associated with
the 8900 series is not available on the Emergency Bypass frame.

Operation
The Emergency Bypass system operates with Kalypso Release 6.0 and
higher software.
Emergency Bypass operation becomes available after the Kalypso system,
Emergency Bypass frame, and the external Router have been properly
installed (see page 12) and configured (see page 19).
Emergency Bypass operation consists of selecting the desired background
and key sources, enabling and disabling bypass mode, and mixing the key
sources on and off air.
Note
Release 6.X software supports background and key source selection only
when Bypass Operating Mode is enabled on the Local Aux panel. Release 7.0
and later software supports source selection when the Local Aux panel is not
actually in Bypass Operating Mode, permitting pre-selection of sources
before activating the mode.
To Select Background Bypass Sources:
Press the button of the desired source on the top source selection bus of the
Local Aux panel. The
Unshift
and
modifier buttons for that bus can be
Shift
used to select additional sources if they have been mapped that way.
To Select Key Sources:
Note
Only key sources from the router can be selected. Direct key sources are fixed
and cannot be changed.
Hold down the
Key 2
button, but continue to hold down
Bypass Deleg
button, then press and release the
Bypass Deleg

source.
2. Release the Bypass Deleg button. This restores the bus to background
selection.
To Enable Bypass Operating Mode:
1. Press and hold down the Bypass Deleg button on the Local Aux panel,
2. Press the Bypass Enable button, then release both buttons.
The currently selected bypass background source will be taken on-air. Any
keys that are turned on will also be included in the bypass output.
To r eturn to normal operation, press and hold down
Bypass Enable and release both buttons to toggle bypass mode off.

To Mix a Key On and Off:
1. Press the Key 1 or Key 2 button (do not hold down the Bypass Deleg
button). That key will mix to the other state (On if Off, or Off if On).
2. The transition rate for each key is determined during configuration. A
transition rate of zero causes a cut.
NoteEach Grass Valley router control system can control a wide variety of
matrices. The type of matrix controlled does not affect operation of the
Kalypso Emergency Bypass option.
•A CIF (communication interface) Module Option must be installed
with its Serial Mezzanine in position 1 of the option module to allow
the SMS 7000 to communicate using native protocol over a serial line.
Encore Router Requirements
•An SIO ISA Mezzanine must be installed for serial communications.
Install Emergency Bypass Frame
The Emergency Bypass frame ships either with the modules pre-installed,
or with the modules packaged separately.
1. Install the Emergency Bypass frame in any suitable rack.
2. If the modules were packaged separately, remove the front cover and
insert the modules into the frame. For cooling efficiency, the modules
should be placed in the following slots:
a. Insert the Bypass Relay module in slot 7.
b. Insert the Bypass Keyer module in slot 8.
c. Insert the Bypass Frame Monitor module into the smaller control
slot 11.
3. Connect the Emergency Bypass frame power cords, using different line
sources if redundant power supplies are being used.
The Local Aux panel is typically powered through a cable connected to the
Main panel. If the Main panel has two power supplies, redundant power
protection for the Local Aux panel already exists. For additional redundancy, an external power supply brick can be connected to the Redundant
DC Power In connector on the Local Aux panel. If desired, two separate
power supply bricks can be connected to the Main and Redundant DC
Power In connectors on the Local Aux panel.
2-M/E Panel
Local Aux control is integrated into the 2-M/E Main panel, but it has a separate processor. It is powered by a direct connection inside the panel. If the
2-M/E Main panel has two power supplies, redundant power protection
for the Local Aux panel already exists. You can optionally add an external
power supply that connects to the Aux Panel Redundant DC Power In connector on the Main panel.
Installation
2-M/E System Cable Replacement
On older 2-M/E Kalypso systems a ribbon cable must be replaced with a
new cable supplied with the Emergency Bypass option. This cable routes
power from the Local Aux panel Backup Power option to the Remote Aux
subpanel. Newer 2-M/E systems are shipped with the correct cable already
installed. This ribbon cable is not used on 4-M/E systems.
Ribbon Cable Identification
1. Open the 2-M/E Main panel lid.
•If a ribbon cable connects three boards in the upper lid near the hinge
(Figure 5), it must be replaced to enable optional backup power with
the Emergency Bypass option. Go to Local Aux Processor Interface Board
Version on page 14.
•If the ribbon cable connects two boards on the lid to the Local Aux Processor Interface board, a new cable is already installed and does not
need to be replaced. Close the lid and go to Control Cabling on page 17.
2. Determine which type of Local Aux Processor board (Figure 5) is
installed in your system. Cable installation is different depending on
board type. The part number of the board is visible behind the fan
assembly.
•If the part number is lower than 671-4945-02, the board will not
work with the Emergency Bypass option. Do not remove or replace
the cable. Contact Grass Valley Customer Service for an upgrade.
•If 671-4945-02, go to Older Board Cable Replacement (671-4945-02) on
page 14.
•If 671-4945-03, go to Newer Board Cable Replacement (671-4945-03) on
page 15.
Older Board Cable Replacement (671-4945-02)
1. Power off the 2-M/E Main panel.
2. Remove the old ribbon cable from the lid (Figure 5).
3. Attach the two closely spaced connectors on the new cable to the same
two boards in the lid (Figure 6). The red marked edge of the ribbon
cable must face down toward the hinge of the lid, to match the pin 1 and
2 side of the connector. These connectors are keyed for this orientation.
4. An interconnecting dual 10-pin header assembly with short and long
pins is provided with the kit. If not already installed, insert the side of
the assembly with the short pins into the remaining open ribbon cable
connector, making sure all connector sockets are filled.
CAUTION Use care when connecting the ribbon cable to the Local Aux Processor Inter-
face board. The connector is not keyed, and equipment damage can occur if
the connector is installed misaligned with the pins.
5. The remaining connector with the header assembly pins protruding
attaches to the J3 connector on the lower left corner of the 671-4945-02
Local Aux Processor Interface board. Orient the cable with the ribbon
emerging from the right side of the connector. The red marked edge of
the ribbon cable must face down toward the bottom of the tub,
matching the pin 1 and 2 side of the connector on the board.
6. Route the cable alongside the power supply (Figure 6), using the
supplied adhesive cable restraints.
7. Close the lid and power up the Main panel.
Newer Board Cable Replacement (671-4945-03)
1. Power off the 2-M/E Main panel.
2. Remove the old ribbon cable from the lid (Figure 5).
3. Attach the two closely spaced connectors on the new cable to the same
two boards in the lid (Figure 7). The red marked edge of the ribbon
cable must face down toward the hinge of the lid, to match the pin 1 and
2 side of the connector. These connectors are keyed for this orientation.
4. An interconnecting assembly with short and long pins is provided with
the kit. If not already installed, insert the side of the assembly with the
short pins into the remaining open ribbon cable connector, making sure
all connector sockets are filled.
CAUTION Use care when connecting the ribbon cable to the Local Aux Processor Inter-
face board.The connector is not keyed, and equipment damage can occur if
the connector is installed misaligned with the pins.
5. The remaining connector with the long pins protruding attaches to the
J2 connector on the lower left corner of the 671-4945-03 Local Aux
Processor Interface board. Orient the cable with the ribbon emerging
from the left side of the connector. The red marked edge of the ribbon

Refer to Figure 8.
•Connect the Router destinations for Key Cut, Key Fill, and Background
signals to the Bypass Keyer Module, using the J connector numbers
shown in the figure. Alternatively, the Key Cut and Fill signals can
come from an external device, but then these signals cannot be
switched from the Kalypso Local Aux panel.
•Connect the Program 1 Output from the Kalypso Video Processor
frame to the Relay Module, as shown. You can also connect another
Program output and a Preview output if you wish.
•Connect the J1 output (Program) from the Keyer Module to the J4 input
of the Relay Module, and the J2 output (Preview) to the J3 input.
•Connect the J6 Program 1 (and J8 Program 2 if used) outputs of the
Relay Module to your downstream targets (monitor, transmitter). The
bypass program output signals are identical.
•Connect the J2 Pvw Out of the Relay Module to a Kalypso system
preview monitor (typically switched preview or PGM PST PVW A).
When Emergency Bypass is not active, this output shows the normal
preview signal. When Emergency Bypass is active, the preview for the
Emergency Bypass keyer is shown, consisting of the current background with both keys on.
Connect a black burst video reference to J9 or J10 on the Keyer module,
either terminated or looped through (Figure 8).
SMS 7000 Router
If the SMS 7000 router is not already configured, you will need to define the
node controller, physical matrix, virtual matrix, levels, sources, and destinations (see the SMS 7000 Configuration Manual).
Confirm that a CIF Module Option is installed, with its Serial Mezzanine in
module position 1. To configure this option for communication with the
Kalypso Local Aux panel:
1. Open your existing Router configuration using the SMS 7000 GUI.
2. Go to Setup/Cfgd Np Internet, and edit NPI1, identifying the levels you wish
the Kalypso system to be able to control.
3. Go to the Serial Amezi menu, and select the Native (& m2100) protocol,
and set it to RS422.
4. Set the following serial settings:
•422 driver, 9600 baud, 8 data bits, no parity, 1 stop bit.
5. In the Co-processors menu, create a new co-processor for this serial
Amezi.
6. If necessary, go to Configuration/Destination and add any new destinations
that will be used for the Emergency Bypass system. You will need to
specify the proper levels if a destination is a video /key pair and note
the names and connector numbers.
7. Send this configuration to the SMS 7000 system. The router is now
configured for serial communication.
Encore router configuration procedures are similar to those used for the
SMS 7000 system. An Encore router communicates to the Kalypso system
via an RCL client. RCL is a superset of the SMS 7000 native protocol. The
Encore serial COM 2 port is configured for RCL at the factory.
Refer to the Encore system documentation for detailed instructions. Specifically, see the Encore Installation and Service Manual for information about
installing the SIO mezzanine, and see the Encore User Manual for configuration instructions.
The Kalypso system must have access to the Encore router serial digital
video and key levels feeding the Emergency Bypass system.
Kalypso System
Relay Module Switch Setting
The Emergency Bypass Relay Module switch must be set to the center
Remote position before the Kalypso system will be able to control it.
Switch position up forces bypass operation, and switch position down
forces normal operation.
Specifying Shaped or Unshaped Sources
The Keyer module can be set to accept shaped or unshaped video for
keying. The same selection is applied to all sources. Settings are retained
when power to the frame is cycled.
1. Set the dial switch on the Keyer Module (slot 8) to the desired mode:
2. Press the toggle switch to enact the change.
•Select 1 for shaped video.
•Select 2 for unshaped video.
Mapping Router Sources
You need to know the exact names of the router sources and destinations
that will be used by the Emergency Bypass system. Router names are case
sensitive, with a maximum of eight characters.
The router sources you use with the Emergency Bypass system must be the
same sources used by the Kalypso system. Any sources connected to the
Kalypso system that are not connected to the router will not be available
when emergency bypass is activated.
Emergency bypass configuration menus are available with Kalypso
Release 6.0 and higher software.
1. Press the Eng Setup button on the Menu panel, touch the System category
selection button, then touch the
