WP-577VH - Overview
3 Overview
The WP-577VH accepts the following signals:
HDMI and PC graphics video
Unbalanced, stereo audio
An RS-232 control or data signal
The WP-577VH encodes these signals and transmits the encoded signal via
DGKat cable to a compatible DGKat switcher or receiver (for example, the
TP-578HDCP, TP-574 or PT-572+). The stereo audio can be embedded into the
output signal.
Using the WP-577VH, you can also communicate via the twisted pair cable:
EDID (Extended Display Information Data)
HPD (Hot Plug Detect) signals from the display device to the source to
trigger the auto-switching facility
The WP-577VH features:
HDCP support
HDTV compatibility
Support for HDMI with x.v. Color™ and 3D
Support for digital audio formats
Automatic live input detection based on 5V presence (HPD)
Automatic switching capabilities to the last connected or priority video input
Automatic analog audio detection and embedding, (auto detection may take
up to 10 seconds)
EDID PassThru –Passes EDID/HDCP signals from source to display

WP-577VH - Overview

Compatibility with all Kramer K-LINK devices which allows the use of
RS-232 for both control of other Kramer devices and sending data to remote,
external RS-232 devices
Equalization and re-clocking of the data
A maximum date rate of 4.95Gbps (1.65Gbps bandwidth per graphic
channel)
Support for Protocol 3000
PowerConnectPlus—a single connection to the transmitter or receiver
powers both units. The higher voltage PowerConnectPlus also powers
regular PowerConnect devices via auto-negotiation
Note: The WP-577VH can supply power to PowerConnect devices but can only
be powered by PowerConnectPlus devices.
The WP-577VH supports a range of:
Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p on shielded
BC-DGKat524 cable
Up to 90m (295ft) at 1080i, or up to 70m (230ft) at 1080p on shielded
BC-DGKat623 cable
Up to 100m (330ft) at 1080i or up to 90m (295ft) at 1080p on shielded
BC-DGKat7a23 cable
Note: The transmission range depends on the signal resolution, graphics card and
display used. The distance using non-Kramer CAT 6 and CAT 7a cables may not
reach these ranges.
3.1 Using TP cables
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer BC-DGKat524 (CAT 5 24 AWG), the
Kramer BC-DGKat623 (CAT 6 23 AWG), and the Kramer BC-DGKat7a23 (CAT
7a 23 AWG) cables. These specially built cables significantly outperform regular
CAT 5/CAT 6/CAT 7a cables.

WP-577VH - Principles of Operation
6 Principles of Operation
This chapter describes the principles of operation of the WP-577VH and
comprises:
Input selection (see Section 6.1)
Input connection timeout (see Section 6.2)
Audio signal priority (see Section 6.3)
Active and passive local RS-232 data modes (see Section 6.4)
Active and passive DGKat RS-232 data modes (see Section 6.5)
The WP-577VH selects video and audio inputs based on the following rules.
6.1 Input Selection
The video selection mode is set by the DIP-switches (see Section 8.1) to:
Manual (external control)
Last connected
Priority
In last connected mode the WP-577VH selects the input that was the last to be
connected. In manual mode the input is selected by sending Protocol 3000
commands. An input selection made by sending a serial command overrides any
other current selection.
In Priority mode the input is selected based on the order of priority which is set
using the control application. The default order of priority is:
1. HDMI
2. VGA

WP-577VH - Principles of Operation

13
This priority remains in force until any of the following occurs:
A Protocol 3000 command is sent
The input signals/connections change
6.2 Input Connection Timeout
The default delay when switching to a new source when either the active source is
lost or a new source is connected is three seconds. The delay when the active
source is lost or a new signal is connected can be changed independently using
the relevant Protocol 3000 command, (see Section 11.2).
When the active source is lost, the delay can be set to between 3 seconds and
unlimited. When a new signal is connected, the delay can be set to between 0
seconds (immediate) and unlimited.
6.3 Audio Signal Priority
The device can automatically detect an analog audio signal.
The audio selection mode is set using the DIP-switches (see Section 8.1) based
on the following table.
DIP-switch #1
DIP-switch #4
Analog Audio Present
Audio Used
On
Not relevant
Yes
Analog
No
HDMI
Off
On
Not relevant
HDMI
Off
Off
Yes
Analog
No
Analog (=mute)
Note: During prolonged periods with no audio (10 seconds), the device may
interpret this as having no analog audio present and therefore switch back to the
embedded audio. To prevent this from occurring set audio selection to manual.
Note: Audio is transmitted even in the absence of video.

WP-577VH - Principles of Operation
6.4 K-Link Active and Passive Local RS-232 Data Modes
The Local RS-232 port can be set to either active or passive mode.
1. In active mode, the data are treated as Protocol 3000 commands and these
provide control of the WP-577VH.
Figure 5 illustrates a sample setup when using the active mode from the local
RS-232 port.
Figure 5: Sample Setup using Active Mode from the Local RS-232 Port
2. In passive mode, the data are treated as raw data and are transmitted over
the DGKat link with no local processing. This data can be used to either
communicate with remote K-link devices (by sending Protocol 3000
commands and by setting the remote device to active mode), or it can be
used to control an external device connected to the RS-232 port of a remote
device (either a K-Link device set to passive mode or a legacy device, for
example, the TP-574).

Figure 6 illustrates a sample setup when using passive mode.
Figure 6: Sample Setup using Passive Mode
Note: In order for the passive mode to function, the RS-232 channel of the DGKat
port must also be set to passive.
6.5 K-Link Active and Passive DGKat RS-232 Data Modes
The DGKat RS-232 port can be set to either active or passive mode.
1. In active mode, the data are treated as Protocol 3000 commands and these
provide control of the WP-577VH.
Figure 7 illustrates a sample setup when using active mode over the remote
DGKat link.

WP-577VH - Principles of Operation
Figure 7: Sample Setup using Active Mode over the Remote DGKat Link
2. In passive mode, the data are treated as raw data and are transmitted over
the DGKat link with no local processing. This data can be used to control an
external device connected to the RS-232 port of a remote K-link device, (see
Section 6.4 for an illustration of the passive mode).
Note: In order for the passive mode to function, the RS-232 channel of the local
port must also be set to passive.
