Overview
Congratulations on purchasing your Kramer DIP-20 Automatic Video Switcher which are part of the
Kramer Audio Distribution System and are ideal for:
•Display systems requiring simple, automatic input selection.
•Multimedia and presentation source selection.
•Video distribution in hotel rooms and schools.
The DIP-20 is a 4K UHD, HDBaseT transmitter and Step−in commander for computer
graphics video, HDMI, unbalanced stereo audio signals embedding and de−embedding. The
DIP-20 accepts HDMI and PC graphics video input, an Ethernet signal, serial data, and an
unbalanced stereo audio input (that is embedded into the output signal). It transmits the signal
via HDBaseT (twisted pair) cable to a compatible receiver (for example, the TP−588D,
TP−580RXR or TP-780RXR).
The DIP-20 is a PoE (Power over Ethernet) provider and can power compatible PoE

DIP-20 –Principles of Operation
10
Principles of Operation
The DIP-20 selects video and audio inputs based on the rules described below.
Input Selection
The video mode selection is set by the DIP-switches (see Setting the Configuration DIP-
switch on page 13) 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.
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 Setting the Configuration DIP-switch on page 13).
Note: When “Audio Only” mode is enabled, 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.

Audio Signal Control
The Option DIP-switches 3 and 4 (see Section Setting the Configuration DIP-switch
on page 13) control the manner in which audio is handled.

When there is an audio signal but no video signal the output is a black video pattern in
conjunction with the external analog Audio In signal.
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.
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 PC/HDMI and GND 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 Accessing the DIP-20 Web Pages on page 15)
•Protocol 3000 commands over RS-232 (see Protocol 3000 on page 38)

•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
Analog Audio Output Volume Control
The analog audio output volume can be controlled using the Web pages, (see Accessing the
DIP-20 Web Pages on page 15) or via the remote, contact-closure switches connected to pins
3 and 4 of the Remote terminal block, (see Connecting the Remote Control Switches
on page 9).
The volume is adjustable from -83dB to +24dB.
