Introduction
Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing
a world of unique, creative, and affordable solutions to the vast range of problems that
confront the video, audio, presentation, and broadcasting professional on a daily
basis. In recent years, we have redesigned and upgraded most of our line, making the
best even better!
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 www.kramerav.com/downloads/PT-12 to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where
appropriate).
Achieving 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 Kramer PT-12 away from moisture, excessive sunlight and dust.
Safety Instructions
Caution:
•This equipment is to be used only inside a building. It may only be connected to
other equipment that is installed inside a building.
•For products with relay terminals and GPI\O ports, please refer to the permitted
rating for an external connection, located next to the terminal or in the User
Manual.
•There are no operator serviceable parts inside the unit.
Warning:
•Use only the power cord that is supplied with the unit.
•To ensure continuous risk protection, replace fuses only according to the rating
specified on the product label which located on the bottom of the unit.

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
www.kramerav.com/support/recycling.
Overview
Congratulations on purchasing your Kramer PT-12 HDMI Controller. PT-12 is a
CEC-enabled TV/display ON/OFF controller and extended EDID processor for
HDMI™signals up to 4K@60Hz (4:2:0) resolution. When PT-12 detects an HDMI
cable plug, it automatically turns ON the connected display, and automatically shuts
OFF the display when signal loss is detected. PT-12 is also a processing tool for
controlling the EDID functions.
Features
•Automates Meeting Rooms –Simplifies meeting beginning and ending by
automatically turning ON a CEC-enabled display when the presentation source is
plugged in and OFF when the source is unplugged. The shutdown delay time is
user-defined.
•High-Performance HDMI Controller –Supports pass-through of signals up to
4K@60Hz (4:2:0) resolution with user control of signal capabilities and functions.
•Selectable HDCP Authorization –Allows the user to control the appearance of an
HDCP or non-HDCP input to the source to permit delivery of protection-free
content, such as personal clips and charts, without HDCP encryption. HDCP
protected content is not passed in non-HDCP mode.
•Video Signal Control –Define color depth attributes and color space capabilities
of pass-through video signal. Lock the EDID configuration to ensure proper video
display.
•Audio Signal Control –User defines whether to allow the full signal to pass
through or to limit the audio to 2 channel LPCM.
•Simple Operation –Includes DIP-switches for defining basic controller functions.
•Cost-Effective Maintenance –Status LED indicators for HDMI ports and power
facilitate easy local maintenance and troubleshooting. Local device management
and firmware upgrade via mini-USB port and DIP-switches, ensure lasting, field-
proven deployment.
•Easy Installation –Compact, fan-less PicoTOOLS® enclosure for device-back
mounting, or side-by-side mounting of 4 units in a 1U rack space with the
recommended Kramer rack adapter.

•Storage temperature –-40to +70C (-40 to +158F).
•Humidity –10% to 90%, RHL non-condensing.
Caution:
•Mount PT-12 before connecting any cables or power.
Warning:
•Ensure that the environment (e.g., maximum ambient temperature & air flow) is
compatible for the device.
•Avoid uneven mechanical loading.
•Appropriate consideration of equipment nameplate ratings should be used for
avoiding overloading of the circuits.
•Reliable earthing of rack-mounted equipment should be maintained.
•Maximum mounting height for the device using supplied brackets is 2 meters.
To mount PT-12 in a rack:
Mount the unit in a rack using the recommended rack adapter
(see www.kramerav.com/product/PT-12).
To mount PT-12 on a table or shelf:
•Attach the rubber feet and place the unit on a flat surface.
•Fasten a bracket (included) on each side of the unit and
attach it to a flat surface.

Configuring PT-12
You can configure PT-12 in the following ways:
•DIP-Switches (see Configuring Using DIP-Switches on page 7).
•EDID Designer Software –to modify the EDID (see Modifying EDID with EDID
Designer on page 9).
•Protocol 3000 API (see Protocol 3000 Commands on page 15).
Configuring Using DIP-Switches
PT-12 enables you to control EDID lock, define signal parameters, configure display
auto power and display auto sleep, and upgrade the device firmware using the DIP-
switches on the back panel.
The following table describes the PT-12 DIP-switches.
By default, all switches are in the OFF (up) position.
All changes in the DIP-switch settings take effect on-the-fly, without the need for a
power cycle.

Feature
Description
1
EDID Lock
OFF (up) –Lock the current EDID so that changes on the output do not result
in changes to the EDID.
ON (down) –EDID is passed-through and acquired automatically.
2
Deep Color
OFF (up) –Limit color depth to 8 bits per color.
ON (down) –Pass-through color depth parameters.
3
Audio Pass-through
OFF (up) –Audio transmission is limited to 2-channel LPCM only.

locked), otherwise, it is ignored.
4
HDCP Operation
OFF (up) –HDCP is disabled, giving the appearance that HDCP is not
supported.
ON (down) –HDCP is enabled, giving the appearance of an HDCP authorized
device to allow unsecured content display by all market-available computer
sources.

Configuring Automatic Power Controls
PT-12 enables you to configure the following automatic power controls for your
connected display:
•Configuring Display Auto Sleep on page 8.
•Configuring Display Auto Power on page 8.
Configuring Display Auto Sleep
As long as there is an active source signal, the connected display remains ON. When
the active source becomes incative, a 5V signal is sent to the display to delay it from
going into sleep (standby) mode. PT-12 enables you to enable/disable and set the
delay time before the 5V output cuts off.
To configure the auto sleep delay:
•Set DIP-switch 6 and 7 to the required position (see Configuring Using DIP-
Switches on page 7).
Configuring Display Auto Power
PT-12 features display auto power via CEC communication. This feature turns ON a
display that is in sleep mode when an active signal is detected and turns it OFF (shuts
down) when the active signal becomes inactive. PT-12 enables you to enable/disable
display auto power and to set the delay time before the display is turned OFF.
Enabling/Disabling Display Auto Power
To enable/disable the display auto power feature:
•Set DIP-switch 5 to the required position (see Configuring Using DIP-Switches
on page 7).
Setting Delay Time for Display Auto Power Shutdown
When the display auto sleep delay (see Configuring Display Auto Sleep on page 8) is
set to a shorter time than the display auto power delay, the 5V does not shut OFF
until display auto power turns OFF the display.
To set the delay time before display auto power shutdown:
•Use the AV-SWITCHING-MODE command (see Protocol 3000 Commands
on page 15).
Defining EDID Lock
PT-12 enables you to define whether to enable the EDID values to be passed through
the device and changed automatically to follow the output or to lock the EDID so that
it will not be affected by changes on the output.
