3 Overview
The Kramer VS-311H is a high performance 3x1 HDCP (high definition
digital content protection) compatible1
The VS-311H switches any one of three HDMI HDCP compliant
automatic switcher for HDMI signals,
digital audio (S/PDIF) signals, and stereo audio signals.
1sources to
a single display device, on HDMI connectors with the corresponding:
•Digital audio (S/PDIF) input signals switched to an S/PDIF output, on
RCA connectors and/or
•Unbalanced stereo audio input signals on 3.5 mini-jack connectors switched
to an unbalanced stereo audio output on a 3.5 mini-jack connector, as well
as to a balanced stereo audio output on a 5-pin terminal block connector
The VS-311H can operate either in the manual mode or in the auto mode.
In the manual mode, the VS-311H acts as a regular switcher, switching the
input video and audio signals to the output via the three front panel INPUT
SELECT buttons.
In the auto mode, you can switch any input to the output via the three front
panel INPUT SELECT buttons, but once the selected video signal is lost, the
machine automatically switches to the highest priority input, according to the
input priority setup2
When selecting an INPUT SELECT button, via the manual or auto mode, that
button illuminates. Pressing an illuminated button deselects that input and that
button no longer illuminates.
. The VS-311H will switch back to the primary input
when an HDMI signal is detected on that input.
The VS-311H is housed in a desktop-sized enclosure and is 12V DC fed.
Control the VS-311H using the front panel buttons, or remotely via:
•RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
•The Kramer infrared remote control transmitter
•The ETHERNET
•Remote control contact closure
1 HDCP is a standard, developed by Intel, to protect copyright holders (movie studios, and so on) from having their programs
copied and shared The HDCP standard provides for the secure, encrypted transmission of digital signals over HDMI or DVI
connections between two HDCP-enabled devices The source device (such as a DVD player or HDTV tuner) encrypts the
digital signal using the HDCP standard, and then sends that signal over the HDMI or DVI connection to the receiving device
(for example, an HDTV) The receiving device decodes the signal using HDCP and uses the signal as it is allowed

•Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
on a single cable
•Benefits consumers by providing superior, uncompressed digital video
quality via a single cable6
•Is backward-compatible with DVI (Digital Visual Interface)
, and user-friendly connector
•Supports two-way communication between the video source (such as a
DVD player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
HDMI has the capacity to support:
•Existing high-definition video formats (720p, 1080i, and 1080p/60), as
well as standard definition formats such as NTSC or PAL
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-
to-analog conversions
2 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI

3 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15m
5 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound HDMI has the capacity to
support Dolby 5 1 audio and high-resolution audio formats
6 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a
simple, cost-effective manner

3.2 Recommendations for Best Performance
To achieve the best performance:
•Connect only good quality connection cables, thus avoiding 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 and position
your VS-311H away from moisture, excessive sunlight and dust

5.1 Setting the DIP-switches
This section describes the machine set-up and DIP-switch selection.
By default, all the VS-311H DIP-switches are set to OFF.
Figure 3and Table 3describe the VS-311H unit DIP-switches.
Figure 3: DIP-switches
Table 3: DIP-switch Settings
DIPS Function Description
1, 2, 3 Priority setup Set the inputs priority (see Table 4)
4 AUTO OFF: manual mode, switch between channels manually;
ON: automatic mode, inputs switch automatically to the
output according to the priority setup
Inputs 1, 2 and 3 can be set in priority according to your needs. The VS-311H will
switch to the secondary input upon loss of the primary input signal, and back to the
primary input when a signal is detected.
Table 4describes the priority setup:

5.1.1 Priority Switching Applications
In the following example, DIP-switches 1, 2, and 3 are set to OFF, OFF and
OFF respectively, meaning that the highest priority input is IN 1; IN 2 is the
secondary input; and IN 3 the third. DIP-switch 4 is set ON, enabling AUTO
mode operation.
If all the inputs are connected, you can, for example, press the INPUT SELECTOR
2 button to switch IN 2 to OUT. The plasma display shows the IN 2 signal.
If the HDMI signal on IN 2 is cut off, the switcher automatically switches IN 1 to
the output, and if that fails too, IN 3 is automatically switched to the output. If, in
the meantime, the IN 2 signal is restored, IN 2 will take priority once again.
5.2 Connecting the Contact Closure Remote Control PINs
The contact closure remote control pins operate in a similar way to the input
buttons.
For example, you may override1the presently routed input by using the
remote control contact closure. To do so2, connect the appropriate input
number3pin on the REMOTE terminal block connector to the G (Ground) pin4,
as Figure 4
DO NOT Connect more than one PIN to the Ground PIN at the same time
illustrates.
To route IN 1 to the
output, temporarily
attach PIN 1 to
PIN G (Ground)
To route IN 2 to the
output, temporarily
attach PIN 2 to
PIN G (Ground)
To route IN 3 to the
output, temporarily
attach PIN 3 to
PIN G (Ground)
Figure 4: Connecting the Contact Closure Remote Control PINS
1 Equivalent to pressing a different input button
2 When in the manual mode (DIP-switch 4 set to OFF), you can switch an input to the output using the front panel INPUT
SELECT buttons
3 Input 1, 2 or 3
4 Note that unless the connection is permanent, the VS-311H will revert to an automatic switcher when the connection is
removed

5.3 Connecting to the VS-311H via RS-232
You can connect to the unit via a crossed RS-232 connection, using for example,
a PC. A crossed cable or null-modem is required as shown in method A and B
respectively. If a shielded cable is used, connect the shield to pin 5.
Method A (Figure 5)—Connect the RS-232 9-pin D-sub port on the unit via a
crossed cable (only pin 2to pin 3, pin 3to pin 2, and pin 5to pin 5need be
connected) to the RS-232 9-pin D-sub port on the PC.
Note: There is no need to connect any other pins.
Figure 5: Crossed Cable RS-232 Connection
Hardware flow control is not required for this unit. In the rare case where a
controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6
on the controller side.
Method B (Figure 6)—Connect the RS-232 9-pin D-sub port on the unit via a
straight (flat) cable to the null-modem adapter, and connect the null-modem
adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually
contains all nine wires for a full connection of the D-sub connector. Because the
null-modem adapter (which already includes the flow control jumpering
described in Method A above) only requires pins 2, 3 and 5 to be connected, you
are free to decide whether to connect only these 3 pins or all 9 pins.

N5 N0 – “INSTRUCTION”
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits) Similarly, if a function is
performed via the machine’s keyboard, then these bits are set with the INSTRUCTION NO , which was performed The
instruction codes are defined according to the table below (INSTRUCTION NO is the value to be set for N5 N0)
2nd BYTE: Bit 7 – Defined as 1
I6 I0 – “INPUT”
When switching (ie instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the INPUT NUMBER which was
switched For other operations, these bits are defined according to the table
3rd BYTE: Bit 7 – Defined as 1
O6 O0 – “OUTPUT”
When switching (ie instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched
Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was
switched For other operations, these bits are defined according to the table
4th BYTE: Bit 7 – Defined as 1
Bit 5 – Don’t care

When several machines are controlled from a single serial
port, they are usually configured together with each machine having an individual machine number If the OVR bit is set, then
all machine numbers will accept (implement) the command, and the addressed machine will reply

Kramer Protocol 2000
17
For a single machine controlled via the serial port, always set M4 M0 = 1, and make sure that the machine itself is
configured as MACHINE NUMBER = 1

NOTES on the above table:
NOTE 2 - These are bi-directional definitions That is, if the switcher receives the code, it will perform the instruction; and if
the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent For example, if the
HEX code
01 85 88 83
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8 If the user switched input 1 to output 7
via the front panel keypad, then the switcher will send HEX codes:
41 81 87 83
to the PC
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by
sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high)
NOTE 15 – When the OVR bit (4th byte) is set, then the “video” commands have universal meaning For example, instruction
1 (SWITCH VIDEO) will cause all units (including audio, data, etc ) to switch Similarly, if a machine is in “FOLLOW”
mode, it will perform any “video” instruction
