Chapter 1 Overview
VIS-PHD44 VIS-PHD88 VIS-PHD1616
The VISSONIC VIS-PHD series HDMI matrix switchers are of high performance and applicable
to computer and video signals with resolutions up to 4K/60 and 4:4:4 chroma sampling. They
support HDMI 2.0 parametric standards, including data rates up to 10.2 Gbps, color depth of 12
bits, 3D, HD lossless audio format, and CEC. These HDCP1.4-compliant matrix switchers adopt
EDID Manager and Key Manager technology, as well as HDMI input equalization and output
pre-emphasis to adapt to different cables and long transmission distances and ensure reliable
system operation. To simplify integration, digital audio from either output can be de-embedded
and output through a digital or analog stereo port. Available in fixed sizes from 4x4 to 16x16, the
VISSONIC VIS-PHD series is ideal for applications requiring reliable, high-performance matrix
switching of 4K/60 HDMI video and audio signals.
The VISSONIC VIS-PHD series matrix switchers can work with computers equipped with a 4K
graphics card, 4K media players, 4K Blu-ray players, and other similar signal sources, as well as
display devices with a physical resolution of 4K. With a maximum data rate of 10.2 Gbps, the
matrix switchers support computer and video signals in 4:4:4 color space, 8-bit color depth, and a
resolution up to 4096x2160/60 Hz. In addition, they provide full support for 1080p/60 signals with
12-bit color depth. To maintain signal integrity, the matrix switchers exploit automatic cable
equalization and output clock recovery to reorder and recover the timing of each HDMI output
video signal. When combined with the VISSONIC VIS-PHD series high-speed HDMI cables,
these features enable 4K signal transmission with a longer distance and compensate for signal loss
from weak source signals or during long-distance transmission, thereby reducing the use of
additional signal conditioning devices. The output also provides power (+5 VDC, 50 mA) for
peripheral devices.
1.1 Main Features
1) Fixed input/output sizes from 4x4 to 16x16.
2) Support for resolutions up to 4Kx2K (YcbCr420)@60 Hz and 4Kx2K@30 Hz.
3) Support for HDMI 2.0 parametric standards, including data rates up to 10.2 Gbps, color depth
of 12 bits, 3D, HD lossless audio format, and CEC.

www.vissonic.com
7VISSONIC Electronics Limited
4) HDMI audio de-embedding, with digital-analog stereo audio output: The VISSONIC
VIS-PHD series can extract embedded HDMI dual-channel LPCM audio to the analog audio
output. HDMI audio can be in compressed or uncompressed format. The output frequency
ranges from 32 kHz to 192 kHz, and the analog audio can be 48 KHz.
5) CEC - Consumer Electronics Control: The control system can trigger built-in standard
CEC commands to operate displays or other video and audio devices connected by HDMI.
Depending on the device manufacturer's settings, functions such as power on/off, input
selection, or volume level are controllable.
6) Comprehensive EDID management: Read the EDID of the output display to the input
HDMI port, or upload a customized EDID file.
7) HDR - High Dynamic Range Video: Provide the video bandwidth, color depth, and
metadata exchange capabilities required for HDR video signals, with support for a larger
contrast range and a wider color gamut.
8) Ultra-fast switching for HDCP-encrypted content.
9) Continuous validation of HDCP standards by Key Manager for fast, reliable switching:
Key Manager validates and maintains continuous HDCP content encryption between input
and output devices, ensuring fast, reliable switching in professional video and audio
environments. It allows the simultaneous distribution of one source signal to two or more
display devices.
10) HDCP 1.4 compliant: Ensure proper display of content-protected media and interoperability
with other HDCP-compliant devices.
11) Support for DDC transmission.
12) HDMI to DVI interface format correction: Automatically correct the HDMI source signal
format to match the DVI display device.
13) Automatic input cable equalization: Actively adjust the incoming HDMI signal to
compensate for signal loss caused by the use of long cables, inferior cables, or source
devices with weak HDMI signal outputs. Automatic output clock recovery: Reorganize
and restore the timing of each HDMI output signal for long-distance transmission via HDMI
cables.
14) +5 VDC, 50mA power provided by HDMI output for powering peripheral devices.
15) Global presetting: For medium to large systems, the 4x4 to 16x16 models allow users to
save up to 9 common input/output configurations and recall them via the front panel,
Ethernet, or serial control. This time-saving feature allows users to set input/output
configurations and save them in memory for future use.
16) Front panel controller: Separate keys for each input and output make operation easier and
more intuitive.
17) Viewing input/output modes: Users can easily view the current switching status of inputs
and outputs via the front panel.
18) Audio separation: Separate analog audio signals from their corresponding video signals.
19) Ethernet monitoring and control: Provide active monitoring, management, or control via
LAN, WAN, or Internet by using standard TCP/IP protocols.
20) RS-232 control port: The matrix switcher can be integrated into the system by using serial
commands.

Chapter 7 Troubleshooting
Fault description
Solution
The matrix cannot be
switched.
● Check whether the command input is correct. The buzzer will
beep when the device receives a correct command, and the
processing result will be returned.
● Check whether the wiring of the device is normal. The "active"
indicator on the front panel will flash when the device receives data.
● Check whether the power supply of the device is normal.
Matrix output has no image.
● Send commands or go to the PC web page to check whether the
corresponding port of the device is working properly, and check the
corresponding firmware version.
● Check the matrix output or PC web page switching to confirm
whether input signals enter the matrix. If there is no signal input,
"noinput" is displayed.
● The matrix will automatically generate a black signal at the
output when there is no input source. Check whether the signal is
detected at the display.
● If there is no problem with the above items but no signal is
detected, check whether the display device works properly, whether
it displays information for the directly connected signal, and
whether it supports the current output resolution of the matrix. If the
resolution is not supported, change the output resolution of the
matrix. You can also connect the matrix directly to the display
device and test whether the display device is normal.
