3 Overview
The VP-81SID can route one of eight TP (Twisted Pair), a DVI or an HDMI input
to either a TP or an HDMI output. Input selection can also be controlled remotely;
• Using Step-In modules (for example, the SID-DP)
• Contact closure switches
• A serial controller via RS-232 or RS-485
• A PC via Ethernet connected over a LAN
The device also outputs balanced and unbalanced stereo audio, as well as digital
audio.
In particular, the VP-81SID:
• Has a bandwidth of 1.65Gbps per video channel
• Can be cascaded with up to four VP-81SID devices via the HDMI port to
provide up to 37 Twisted Pair inputs
• Supports the SID range of Step-in Commander panels for remote inputs and
remote step-in control
• Has a USB power port that can provide power to USB devices, (for
example, the Kramer KW-11T)
• Is HDCP compliant
• Provides EDID capture – Copies and stores the EDID from a display device
You can control the VP-81SID using the front panel buttons, or remotely via:
• RS-485 or RS-232 serial commands transmitted by a touch screen system,
PC or other serial controller
• Ethernet over a LAN
• The Kramer RC-IR3 Infrared Remote Control Transmitter or the
C-A35M/IRR-50 infrared remote extension cable transmitter (optional)
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 that may
adversely influence signal quality and position your VP-81SID away from
moisture, excessive sunlight and dust

3.1 Defining EDID
The Extended Display Identification Data (EDID
1
) is a data-structure, provided by
a display that describes its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the PC or laptop to “know” what kind of
monitor is connected to the output. The EDID includes the manufacturer’s name,
product type, timing data supported by the display, display size, luminance data
and (for digital displays only) pixel mapping data.
3.2 About HDMI—General Description
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital
2
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the highest high-definition image and sound quality. Note that
Kramer Electronics Limited is an HDMI Adopter and an HDCP Licensee.
In particular, HDMI
3
:
• Provides a simple
4
interface between any audio/video source, such as a settop box, DVD player, or A/V receiver and video monitor, such as a digital
flat LCD / plasma television (DTV), over a single lengthy
5
cable
• Supports standard, enhanced, high-definition video, and multi-channel
digital audio
6
on a single cable
• 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
7
, and user-friendly connector
• Is backward-compatible with DVI (Digital Visual Interface)
• Supports two-way CEC 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
1 Defined by a standard published by the Video Electronics Standards Association (VESA)
2 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-to-analog
conversions
3 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI licensing LLC
4 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
5 HDMI technology has been designed to use standard copper cable construction at up to 15m
6 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
7 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-
effective manner
Page 9
Overview
5
• HDMI has the capacity to support existing high-definition video formats
(720p, 1080i, and 1080p, 2K and 4K), standard definition formats such as
NTSC or PAL, as well as 480p and 576p.
3.3 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.
3.4 About the Power Connect™ Feature
The Power Connect™ feature here means that digital Step-In Commanders (for
example, the SID-DP and SID-DVI) do not require an independent power supply
if the distance between the VP-81SID and the Step-In Commander does not exceed
50m (164ft). The Power Connect™ feature applies as long as the cable can carry
power. For longer distances heavy gauge cable or a power adapter should be used.
Note: Analog Step-In Commanders (for example, the SID-VGA and SID-X1) do
require independent power supplies.
3.5 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer BC-DGKat623 (CAT 6 23 AWG cable),
and the Kramer BC-DGKat7a23 (CAT 7a 23 AWG cable). These specially built
cables significantly outperform regular CAT 6/CAT 7a cables.
In applications where plenum cable is required, use the Kramer BCP-DGKat724
(CAT 7 23 AWG cable).

14.6 Command Terms
Command
A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-').
Command and parameters must be separated by at least one space.
Parameters
A sequence of alphameric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special
characters for specific commands). Parameters are separated by commas.
Message string
Every command entered as part of a message string begins with a message
starting character and ends with a message closing character.
Note: A string can contain more than one command. Commands are separated by a
pipe ( '|' ) character.
Message starting character
'#' – For host command/query
'~' – For machine response or machine command performed by keystroke operation
on the front panel or IR remote controller.
Device ID (Optional when directly connected to the device)
K-NET Device ID or MACHINE NUMBER followed by '@'
(ex. #02@
CRLF )
Query sign
'?' follows some commands to define a query request.
All outputs sign
'*' defines all outputs.
Message closing character
CR – For host messages; carriage return (ASCII 13)
CRLF – For machine messages; carriage return (ASCII 13) + line-feed (ASCII 10)
Command chain separator character
When a message string contains more than one command, a pipe ( '|' ) character
separates each command.
Spaces between parameters or command terms are ignored.
14.7 Entering Commands
You can directly enter all commands using a terminal with ASCII communications
software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial,
Ethernet, or USB port on the Kramer device. To enter
CR , press the Enter key.
( LF is also sent but is ignored by command parser).
For commands sent from some non-Kramer controllers like Crestron, some
characters require special coding (such as, /X##). Refer to the controller manual.
Page 47
Protocol 3000 Syntax
43
14.8 Bi-directional definition
All commands are bi-directional. That is, if the device receives the code, it will
perform the instruction; and if the instruction is performed (due to a keystroke
operation on the front panel or IR controller), then these codes are sent to the PC or
other RS-232 / Ethernet / USB controller.
14.9 Command Forms
Some commands have short name syntax in addition to long name syntax to allow
faster typing. The response is always in long syntax.
14.10 Command Chaining
Multiple commands can be chained in the same string. Each command is delimited
by a pipe character ( '|' ). When chaining commands, enter the message starting
character and the message closing character only once, at the beginning of the
string and at the end.
Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.
14.11 Maximum String Length
64 characters
