DIP-20 - Getting Started
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerav.com/downloads/DIP-20 to check for up-to-
date user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your DIP-20 Automatic Video Switcher away from moisture,
excessive sunlight and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
2.2 Safety Instructions
Caution:
There are no operator serviceable parts inside the unit
Warning:
Use only the power cord that is supplied with the unit
Warning:
Do not open the unit. High voltages can cause
electrical shock! Servicing by qualified personnel only
Warning:
Disconnect the power and unplug the unit from the
wall before installing

2.3 Shielded Twisted Pair/Unshielded Twisted Pair
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer BC-HDKat6a (CAT 6 23 AWG) HDBaseT
certified, and the Kramer BC-DGKat7a23 (CAT 7a 23 AWG) cables. These
specially built cables significantly outperform regular CAT 6 and CAT 7a cables.
2.4 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country
go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

DIP-20 - Overview
3 Overview
The DIP-20 accepts an HDMI and PC graphics video input, an Ethernet signal,
serial data, and an unbalanced stereo audio input (which is embedded into the
output signal), and transmits the signal via HDBaseT (Twisted Pair) cable to a
compatible receiver (for example, the TP-588D or the TP-580RXR). The
DIP-20 is a PoE (Power over Ethernet) provider and can power compatible PoE
acceptors, (for example, the TP-588D and the TP-590RXR).
The DIP-20 provides a range of up to 130m (427ft) in normal mode for
1080p@60Hz @36bpp, and 100m (328ft) for 4K @30Hz. When using an extended
range receiver and BC−HDKat6a cables, the range is up to 180m (590ft) for
1080p@60Hz @24bpp. To use the DIP-20 in extended range mode you must edit
the EDID.
For optimum range and performance, use Kramer's BC−HDKat6a and
BC−DGKat7a23 shielded twisted pair (STP) cables. Note that the
transmission range depends on the signal resolution, graphics card and
display used. The distance using non-Kramer CAT 6 and CAT 7 cables
may not reach these ranges.
The DIP-20 Automatic Video Switcher features:
Support for 4K UHD (data rate of up to 10.2Gbps)
Automatic live input detection based on video clock presence
Automatic input selection based on priority selection or last connected input
Manual input selection
Automatic analog audio detection and embedding
Power over Ethernet which passes electrical power along with data over
Ethernet cabling. This allows a single cable to provide both data connection
and electrical power to compatible devices
Control via Kramer Protocol 3000 and embedded Web pages over a LAN
HDTV support
HDMI with Deep Color, x.v.Color™ and 3D
HDCP compliancy—works with sources that support HDCP repeater mode

3.1 About HDBaseT™ Technology
HDBaseT™ is an advanced, all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the ProAV –and also the home –
environment as a digital networking alternative, where it enables you to replace
numerous cables and connectors by a single LAN cable used to transmit, for
example, uncompressed, full high-definition video, audio, IR, as well as various
control signals.
The products described in this user manual are HDBaseT certified.

DIP-20 - Principles of Operation
6 Principles of Operation
The DIP-20 selects video and audio inputs based on the rules described below.
6.1 Input Selection
The video mode selection is set by the DIP-switches (see Section 8.1) to either
of the following modes:
Manual
Auto—Last connected or priority mode
In manual mode switching occurs whether or not there is a live signal present
on the input. You select manually select an input using any of the following
methods:
Front panel buttons
Remote input selection switches
RS-232 control
The Web pages
In auto mode, the switching selection is performed based on either last
connected or priority input.
In last connected mode, if the signal on the current input is lost, the DIP-20
automatically selects the last connected input, (the delay depending on a
configurable timeout).
In priority mode, when the input sync signal is lost for any reason, the input with
a live signal and next in priority is selected automatically, (the delay depending
on the configurable signal-lost timeout). This priority is configurable; the default
setting is HDMI 1 →HDMI 2 →PC.
Note: In both last connected and priority modes, manually selecting an input
(using the remote input selection switches or any of the above methods)
overrides automatic selection.

DIP-20 - Principles of Operation
13
6.2 Signal Loss and Unplugged Cable Timeouts
In both last connected and priority modes, when the input signal sync is lost
(but the cable is not removed) there is a default delay (ten seconds for video,
not applicable to the PC input, and five seconds for analog audio) before
another input is automatically selected. When an input cable is removed, there
is a delay before automatic switching takes place.
Both timeouts are configurable, (see Section 8.1).
Note: Analog audio is not output when there is no display connected. If a
display is connected analog audio is output even in the absence of a video
signal.
6.3 Audio Signal Control
The Option DIP-switches 3 and 4 (see Section 8.1) control the manner in which
audio is handled.
The following table describes which audio signal is embedded in the output.

DIP-20 - Principles of Operation
Note: The default timeout for audio switching when the input signal is lost is
five seconds. This can be changed using either P3000 commands or the Web
pages.
6.4 VGA Phase Shift
To minimize phase on the input VGA signal, the VGA sampling phase can be
shifted using the following methods:
A long press on the PC IN select button on the front panel.
Each long press steps the phase shift up one step, starting from 0 and
going to 31. When set to 31, another long press steps the shift to 0
A remote, contact-closure switch connected to pins 1 and G of the
Remote terminal block.
Each long press steps the phase shift up one step, starting from 0 and
going to 31. When set to 31, another long press steps the shift to 0
Using the Web pages, (see Section 9.1)
Protocol 3000 commands over RS-232 (see Section 12)

7 Operating the DIP-20
The DIP-20 can be operated using any of the following methods:
Front panel buttons
Protocol 3000 command, (see Section 12)
Remote contact-closure switch, (see Section 5.1)
Web pages, (see Section 9)
7.1 Locking the EDID
To prevent the stored EDID (either default or read from a device) from being
overwritten, either send a Protocol 3000 command or use the Web pages.
7.2 Resetting the DIP-20
To perform a soft reset of the DIP-20:
Briefly press the Reset button.
The device resets
To reset the DIP-20 to factory default parameters:
Press and hold the Reset button for five seconds.
The device is reset to factory default parameters
7.3 Analog Audio Output Volume Control
The analog audio output volume can be controlled using the Web pages, (see
Section 9.1) or via the remote, contact-closure switches connected to pins 3
and 4 of the Remote terminal block, (see Section 5.1).
The up/down volume steps per press are detailed in the table below.
