Kayak Production Switcher
You should see source names and tallies from the Kahuna switcher on the monitor wall.
Kayak Production Switcher
A multiviewer can receive dynamic source names and tally information from Thomson
Grass Valley production switchers that support the ACOS protocol, including the KayakDD,
Kayak HD/SD, DD35, and XtenDD HD/SD series. The procedures below describe how to set
up a multiviewer to interface with these Thomson Grass Valley switchers, for which the
generic name Kayak switcher will be used.
Configuring the Kayak Switcher
Once you have established a serial connection between the switcher and your multiviewer,
you will need to enable the ACOS protocol on the switcher’s serial port by using the
Sidepanel software.
To set up the Kayak switcher
1 Physically connect one end of an RJ-45 straight cable to the multiviewer’s RS-422 port.
2 Using a DE-9S-to-RJ-45 crossover adapter (Miranda part no. 1792-3700-100), connect
the other end of the cable to one of the RS-422 control ports on the Kayak switcher. The
illustration below shows the location of the RS-422 ports on a 4RU Kayak
HD switcher.
The RS-422 ports (highlighted) are numbered 1 – 8, from top to bottom. Refer to your
switcher’s Installation and Service Manual for more details.

Note: The on-air tally feature was introduced in version 6.9.3 of the ACOS
protocol, which is only available with the Kayak series of Thomson Grass
Valley production switchers. Other features such as retrieving dynamic
source or destination names, and changing crosspoints are available on all
ACOS-enabled production switchers.
