Overview
2
A main advantage of the VS-1616SDI is that it forms part of the series of
16x16 matrix switchers that includes, but is not limited to, VS-1616A (a
16x16 analog balanced stereo audio matrix switcher), VS-1616V (a 16x16
analog video matrix switcher), VS-1616AD (a 16x16 digital audio matrix
switcher), VS-162V (a 16x16 video matrix switcher), and VS-162AV (a
16x16 audio-video matrix switcher).
In particular, the VS-1616SDI:
Is a true matrix switcher, enabling the user to simultaneously route
any or all of the 16 inputs to any or all of the 16 outputs
Provides automatic equalization for losses on 75co-axial cable
Reclocks each output to provide 16 low-jitter serial digital outputs
Has automatic video standard recognition
Accepts either analog or serial video as the external source for its
vertical trigger. Alternately, input # 1 can be assigned as the sync
source
In addition the VS-1616SDI:
Can be configured into a Kramer multi-signal switcher system
including digital and analog video, digital and analog audio, and
RS-422 control switchers
When integrated in a system, all units switch in true audio-follow-
video mode
Recalls up to 99 configuration setups via the non-volatile memory
and provides for an unlimited quantity of setups when using the
Kramer control software on your PC
Includes a user-friendly LCD display (making operation even
easier)
With its FLASH memory, lets you upgrade to the latest Kramer
firmware version via Internet download
Comes with a choice of protocol format: hexadecimal or ASCII
You can control the VS-1616SDI using:
The front panel buttons
Remotely, by RS-485 or RS-232 serial commands transmitted by
a touch screen system, PC, or other serial controller
Remotely, from the Kramer RC-IR2 Infra-Red Remote Control
Transmitter
External dry-contact push-buttons

Operating a Single Machine
3
To achieve the best performance:
Use only good quality connection cables
1
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your
VS-1616SDI away from moisture, excessive sunlight and dust.
4 Operating a Single Machine
By default, the VS-1616SDI is setup for use as a single machine. This
means that it is:
A 16x16 SDI video switcher
Switched during the vertical interval of the external analog reference
In particular, be sure that the dipswitches are set as shown in Figure 1 (see
section 6.3 for further details). To operate a single machine, see Table 1.

6 Installing the SDI Video Matrix Switcher
To install the VS-1616SDI, connect the following
1
to the rear panel, as
required:
Power cord
Video input and output cables
Control Interface cables between switcher units, or PC (or other
controller), as section 6.4 describes
Set the dipswitches, as section 6.3 describes
Set the system variables using the MENU function, as section 8
describes
Using the VS-1616SDI unit and/or other 16x16 matrix switchers in the
series
2
, you can assemble the following kinds of systems:
A stand alone switcher (see section 6.1)
A system of interconnected switchers (see section 6.2)
6.1 Configuring a Standalone SDI Video Matrix Switcher
By default, a single VS-1616SDI unit is configured as a 16x16 stand alone
switcher for SDI video with 16 inputs and 16 outputs, as Figure 3 illustrates:
Figure 3: Configuring a Stand Alone 16x16 VS-1616SDI Switcher
1 Switch OFF the power on each device before connecting it to your VS-1616SDI
2 Including the VS-1616A (a 16x16 analog balanced stereo audio matrix switcher), the VS-1616V (a 16x16 analog video
matrix switcher), the VS-1616AD (a 16x16 digital audio matrix switcher), VS-162V (a 16x16 video matrix switcher), and the
VS-162AV (a 16x16 audio-video matrix switcher)

Installing the SDI Video Matrix Switcher

6.2 Assembling a System of Interconnected Switchers
A major advantage of the VS-1616SDI is that it belongs to the series of
16x16 matrix switchers and, as such, can interconnect with other switchers
in the series. This series includes, but is not limited to, VS-1616A (a 16x16
analog balanced stereo audio matrix switcher), VS-1616V (a 16x16 analog
video matrix switcher), VS-1616AD (a 16x16 digital audio matrix
switcher), VS-162V (a 16x16 video matrix switcher), and VS-162AV (a
16x16 audio-video matrix switcher).
The block diagram in Figure 4 illustrates how to assemble an interconnected
varied-format 16x16 series switcher that consists of a 32x32 composite
video matrix switcher, a 16x16 digital video matrix switcher, a 32x32
balanced stereo audio matrix switcher, and a 16x16 digital audio matrix
switcher.
Note that each group of switchers has a unique MACHINE # that is shared
by all members of the group. In Figure 4, the 32x32 composite video matrix
switcher is MACHINE # 1, the 16x16 digital video matrix switcher is
MACHINE # 2 and so on. Control of the system is via the MACHINE #’s.

with RS-232
OFF = RS-232 connection via a null modem adapter
ON = RS-232 connection without a null modem adapter
8 RS-485 termination for first and last machine = ON (RS-485 line terminates with
110); for others = OFF (RS-485 line is open)
6.3.1 Setting the MACHINE #
To control a unit via RS-232 or RS-485, each unit has to be identified via its
unique MACHINE #.
Set the MACHINE #
2
on a VS-1616SDI unit according to Table 5.
A valid MACHINE # is from 1 to 15.

6.3.2 Understanding the SYSTEM Mode
The terms audio-follow-video
1
and audio breakaway
2
are well known.
Sometimes signals other than audio signals need to switch simultaneously
and at other times, need to switch independently. For example:
Non-linear editing systems, that sometimes combine video with
analog audio and at other times combine video with digital audio
Duplication systems, that make Master tapes from programs with
different formats: composite analog, component analog and
component digital
DIP 5 defines whether the VS-1616SDI unit communicates with other
switchers via a common control line.
You can set DIP 5 OFF to disable the Follow-SYSTEM mode in stand alone
switcher applications
3
.
You must set DIP 5 ON to enable the Follow-SYSTEM mode in an
interconnected varied-format switcher application
4
.
Refer to section 8.2 for a description of the MENU’s Follow-SYSTEM and
Breakaway-from-SYSTEM modes.
6.3.3 Understanding the SLAVE Mode
The SLAVE mode is only used for the multi-channel video switcher
configuration, for example, when joining together VS-1616V analog video
and VS-1616SDI digital video units.
One unit is used as the Master, and the other unit is the Slave. The Slave
always follows the Master. In the example the first VS-1616V unit is the
Master (with DIP 6 set OFF disabling the Slave mode) and the second
1 Video and the audio channels switch simultaneously in the same way
2 Audio channels switch independently from the video channels
3 See section 6.1
4 See section 6.2

Installing the SDI Video Matrix Switcher
11
VS-1616SDI unit is the Slave (with DIP 6 set ON enabling the Slave
mode).
On the Slave VS-1616SDI unit, the MATRIX and STATUS Displays do
not illuminate and the STATUS Display shows the following message:
Keyboard LOCKED
However, the STATUS Display on the Slave VS-1616SDI unit dynamically
shows
1
all changes made from the Master VS-1616V unit (which are
implemented also on the Slave unit).
Front panel control is via the Master VS-1616V unit, on which the front
panel buttons are unlocked and both the MATRIX and STATUS Displays
illuminate.
6.4 Connecting a Control Interface
Connect a control interface (RS-232 or RS-485) unless operating a
VS-1616SDI as a stand alone unit without any control device (that is, with
control from the front panel or IR port, and not via a remote controller or a
PC).
The control interface must be identical on each switcher in the series of
16x16 matrix switchers; either RS-232 or RS-485. One control interface
suffices. Do not use both RS-232 and RS-485 control interfaces in the same
configuration. For example, in an interconnected varied-format 16x16
switcher application
2
,if the switcher that connects to the PC connects via
the RS-232 control interface, each switcher must interconnect via the
RS-232 control interface and not via the RS-485 control interface.
Choose the RS-232 control interface, for a range of up to about 25 meters
used for a point-to-point connection.
Choose the RS-485 control interface, to operate the switcher for a distance
of up to 1000 meters.
6.4.1 Connecting the RS-232 Control Interface
Connect several switchers (from the series of 16x16 matrix switchers) and
the control unit in an RS-232 daisy chain arrangement, with or without
using a Null-modem adapter, as Figure 6 illustrates.
1 Albeit with an LCD Display that does not illuminate
2 See section 6.2

KRAMER: SIMPLE CREATIVE TECHNOLOGY

12
The RS-232 daisy chain switcher arrangement is transparent. This lets you
arrange the switchers (from the series of 16x16 matrix switchers) according
to your requirements, and not according to a fixed sequence dependent on
the MACHINE #.
Figure 6: Connecting a PC to Four Switchers
