2 DIP-31M - 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 www.kramerav.com/downloads/DIP-31M 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-31M 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

3.1 About Maestro
DIP-31M showcases Maestro, Kramer’s easy to configure, single-trigger room
automation software that creates customized meeting room environments with
minimal end-user intervention.
Maestro creates a series of actions based on a pre-defined event, or trigger, such
as plugging in a laptop or turning a display off. These events can trigger actions
such as turning on computers (via Wake-on-LAN) and turning on and off lights,
projectors, displays, video sources, and HVAC.
Integrated with Kramer’s dynamic database of device drivers, there is no end to the
types of actions Maestro can perform. Maestro enables automated control over a
variety of port types: RS-232, Ethernet, GPIO, relay, and IR.
Maestro makes meeting rooms environmentally-friendly by ensuring that lights and
devices are automatically turned off. The solution turns a device or series of devices
on or off based on triggers, e.g., removing inputs, time, etc. This helps create a
greener workplace, and over time, saves significant energy costs.

12 DIP-31M - Principles of Operation
6 Principles of Operation
The DIP-31M selects video and audio inputs based on the rules described below.
6.1 Input Selection and Switching
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 can manually select an input using any of the following methods:
•Front panel buttons.
•Remote input selection switches.
•RS-232 control.
•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-31M
automatically selects the last connected input, (the delay depending on the
configurable signal-lost 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.
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-31M - 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 9.5).
If no display is connected, analog audio is not output.
If a display is connected, analog audio is output even in the absence
of a video signal.
6.3 Audio Signal Control
Setup DIP-switches 3 and 4 (see Section 8.1) control how audio is handled.
The following table describes which audio signal is embedded in the output.

When there is an audio signal but no video signal, the output is a black video

14 DIP-31M - Principles of Operation
6.4 VGA Phase Shift
To minimize phase sync misalignments 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).
•Protocol 3000 commands over RS-232 (see Section 13).

7 Operating the DIP-31M
The DIP-31M can be operated using any of the following methods:
•Front panel buttons.
•Remote contact-closure switch, (see Section 5.1).
•Web pages, (see Section 9).
•Protocol 3000 commands, (see Section 13).
7.1 Locking the EDID
To lock the EDID and prevent the stored EDID (either default or read from a device)
from being overwritten:
•Send a Protocol 3000 command, (see Section 13).
•Use the Web pages, (see Section 9.7).
7.2 Resetting the DIP-31M
The DIP-31M can be reset to factory default by either:
•Using the button on the rear panel.
•Using the Web pages, (see Section 9.3.2).
To perform a soft reset of the DIP-31M:
•Briefly press the Reset button.
The device resets.
To reset the DIP-31M to factory default parameters:
•Press and hold the Reset button for five seconds.
The device is reset to factory default parameters.

16 DIP-31M - Operating the DIP-31M
7.3 Controlling Analog Audio Output Volume
The analog audio output volume can be controlled using the Web pages, (see
Section 9.3) or via the remote, contact-closure switches connected to pins 3 and 4
of the Remote terminal block, (see Section 5.1).
The volume is adjustable from -83dB to +24dB.
