CONNECTING TO A PC
To connect directly to a PC without using the KRAMER Null-Modem Adapter, make connections as in Figure
1. To use the KRAMER Adapter instead (recommended), plug one end into the PC's serial port, then connect
from the other end to the switcher using a 9-pin flat-cable. Alternatively, connect only pins 2, 3, and 5 from the
Adapter to the switcher (one-to-one connection).
11.1 New Protocol 2000
All the switcher described in this manual have built-in a dual communication protocol option. The standard
protocol described in this manual allows simple and fast control of a single switcher or several machines
connected together. The new communication protocol named PROTOCOL 2000, allows the user to control
several different switchers or switchers/matrix groups from one screen. The PC software backing up the new
protocol is called K-ontrol, allowing viewing and monitoring four different machines, which have protocol
2000 built-in from one screen. The new protocol allows more control over the switchers, but is more
complicated than the current protocol supported by the K-Switch software.
The full set of software and documentation is available on the software CD and on Kramer’s website free for
download. The new software package allows the user to install all versions of software suitable for the machine
used. For the machines described in this manual, both the K-Switch and the K-ontrol software may be installed.
11.1.1
Changing communication protocols
You can work with one of 2 protocols. To work with PROTOCOL 2000, simultaneously press buttons 1 and 4
on the front panel and turn the machine off for at least 5 seconds. When you turn on the machine, it will use
PROTOCOL 2000. Alternatively, you can work with the old protocol. To do so, simultaneously press buttons 1
and 3 on the front panel and turn the machine off for at least 5 seconds. When you turn on the machine, it will
use the old protocol.
11.1.2
Additional software options
The latest version of the K-switch program allows the user to convert any of the switchers described in this
manual to a very sophisticated sequential switcher with no extra cost. The program allows full control on the
switching sequence, dwell time for each input etc. The latest software upgrades are available at Kramer’s web
site: www.kramerelectronics.com at the technical support section.

USING THE SWITCHER
12.1 Powering on the Switcher
The switcher should only be powered on after all connections are completed and all source devices have been
powered on. Do not attempt to connect or disconnect any video, audio or control signals to the switcher while it
is powered on. The switcher may be powered on by pressing the toggle switch on the far-left front panel to the
up position. In the up position, the toggle switch glows, and the active input button illuminates as well.
12.2 Operating an Individual Switcher
NOTE
The operation of all the switchers described in this manual is similar. The VS-1211 operation is described and may
be applied accordingly to the others.
Operation of the VS-1211 switcher units by local control is as follows:
1. Connect up to twelve video/audio-stereo sources to the input sockets of the switcher.
2. Connect a video/audio-stereo acceptor to the output socket of the switcher.
