WP-20 –Principles of Operation
10
Principles of Operation
The WP-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 Configuration DIP-switch
on page 13) to either of the following modes:
•Manual.
•Auto –Last connected or priority mode.
When in manual override mode, a manual switch to an unconnected input stays connected to
output. The device does not go into auto-switch mode.
In manual mode you select an input using, either the remote input selection switches, the
Web-page interface, or P3000 commands, and switching occurs whether or not there is a live
signal present on the input.
In auto mode, the switching selection is performed based on either last connected or priority
input.
In last connected mode the WP-20 selects the input based on which input was connected last.
If the signal on this input is subsequently lost for any reason, the input with a live signal and
which was also the last connected is selected automatically.
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. This priority is configurable; the default setting is
HDMI > PC.
In both last connected and priority modes, manually selecting an input using the remote input
selection switches or the web pages (see Switching Input Signals on page 18) overrides the
last automatic selection until the next connection event or power cycle.
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 Configuration DIP-switch on page 13).
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.

Kramer Electronics Ltd.
WP-20 –Principles of Operation

Audio Signal Control
The Option DIP-switches 3 and 4 (see Setting Configuration DIP-switch on page 13) control
the manner in which 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 pattern in
conjunction with the external analog Audio In signal.
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 optimize 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 Accessing WP-20 Web Pages on page 15).
•Protocol 3000 commands over RS-232 (see Protocol 3000 on page 43).
VGA phase default value is 6.

Operating WP-20
Powering up the WP-20 recalls the last settings from the non-volatile memory, (that is, the
configuration of the device when it was powered down).
Selecting an Input Manually
Any of the following methods can be used to select an input:
•Protocol 3000 command, (see Protocol 3000 on page 43).
•Remote contact-closure switch, (see Remote Switches Terminal Block on page 9).
•Web pages, (see Operating WP-20 Remotely Using Web Pages on page 15).
Locking EDID
To prevent the stored EDID (either default or read from a device) from being overwritten, you
can lock the current EDID by either sending a Protocol 3000 command or by using the web
pages.
Do not power up the display before locking the EDID.
Resetting WP-20
To perform a soft reset of the WP-20:
•Briefly press the Reset button.
The device resets.
To reset the WP-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
WP-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 Remote Switches Terminal Block on page 9) and
for using P3000 commands to control the volume (see Protocol 3000 on page 43).
The volume is adjustable from -83dB to +24dB in steps of 0.5dB.
Upper and lower volume ranges may vary depending on the version of your device hardware.
The ranges are displayed on the Routing Video and Data webpage (see Routing Video and
Data on page 17).
