In particular, HDMI:
• Provides a simple interface between any audio/video source, such as a set-
top box, DVD player, or A/V receiver and video monitor, such as a digital flat
LCD / plasma television (DTV), over a single lengthy cable
SIMPLICITY - 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
LENGTHY CABLE - HDMI technolog y has be en desi gned to use standard copper ca ble
construction at up to 15m
• Supports standard, enhanced, high-definition video, and multi-channel digi t al
audio on a single cable
MULTI-CHANNEL DIGITAL AUDIO - H D MI sup po rts 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
• Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
• Benefits consumers by providing superior, uncompressed digital video
quality via a single cable, and user-friendly connector
HDMI provides the qualit y and functionality of a digital interfac e whi le als o sup por ti ng
uncompressed video formats in a simple, cost-effective manner
• Is backward-compatible with DVI (Digital Visual Interface)
• Supports CEC, 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
• Has the capacity to support existing high-definition video formats (720p,
1080i, and 1080p @60Hz), standard definition formats such as NTSC or
PAL, as well as 480p and 576p
3.2 About HDCP—General Description
The High-Bandwidth Digital Content Protection (HDCP) standard developed by
Intel protects digital video and audio signals transmitted over DVI or HDMI
connections between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios) from
having their programs copied and shared, the HDCP standard provides for the
secure and encrypted transmission of digital signals.

5.1 Connecting to the VS-161H Using the RS-232 Connection
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 3
crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be
connected) to the RS-232 9-pin D-sub port on the PC.
Note: There is no need to connect any other pins.

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 4
)—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.

6 Operating the VS-161H 16x1 HDMI Switcher
This section describes:
• The PC and DVD modes (see Section 6.1
• Acquiring the EDID (see Section 6.2)
• Locking and unlocking the front panel buttons (see Section 6.3)
• Resetting to the factory default values (see Section 6.4)
• Upgrading the firmware (see Section 6.5)
6.1 The PC and DVD Modes
The VS-161H has two operation modes that are specific per input: the PC mode
and the DVD mode:
• The PC mode is used when connecting a computer or several computers to
one or more of the inputs via a DVI-to-HDMI converter cable (for example,
the Kramer HDMI-DVI Gold Plated Cable in various lengths). This is the
default mode
• The DVD mode is used when connecting a DVD or several DVDs to the
inputs
When in the PC mode, the input has access to the EDID (default or acquired) to
prevent the computer from resetting if an output is not connected. In the DVD
mode, the EDID of the connected output is available only when the input to which
the DVD is connected, is switched to the output.
)
The PC mode and the DVD mode can be applied to a single input or to several
inputs. For example, if you want to connect a computer to INPUT 1, another
computer to INPUT 2, and DVD machines to all the other inputs (from INPUT 3 to
INPUT 16), set INPUT 1 and INPUT 2 to the PC mode and all the other inputs to
the DVD mode.
To set the inputs to either the PC or the DVD mode:
1. Turn the power off.

9 Kramer Protocol 2000
The Kramer Protocol 2-000 RS-232/RS-485 communication uses four bytes of
information as defined below. All the values in the table are decimal, unless
otherwise stated.
0 D N5 N4 N3 N2 N1 N0
2nd byte
MACHINE NUMBER
1st BYTE: Bit 7 – Defined as 0.
D – “DESTINATION”: 0 - for sending information to the switchers (from the PC);
1 - for sending to the PC (from the switcher).
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 cod es ar e de fi ned 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 o per a ti ons, these bits are de fi ne d acc or ding 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.
OVR – Machine number override.
M4…M0 – MACHINE NUMBER.
Used to address machines in a system via their machine numbers. 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 accept (implement) the command, and the addressed machine replies. 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 tabl e:
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it performs 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) switches input 5 to output 8. If the user switched input 1 to output 7
via the front panel keypad, then the switcher sends 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) causes all units (including audio, data, etc.) to switch. Similarly, if a machine is in
“FOLLOW” mode, it performs any “video” instruction.
