High Quality Picture - No Signal Loss and Digital Noise Free
Our switchers are built to deliver the highest quality picture preserving the
native resolutions of the video sources without any signal loss. At the same
time, the digital noises that may affect the picture quality will be eliminated.
Due to the nature of the digital signals and passing through multiple stages of
connection when using switchers, it is important to eliminate the digital noises
and boost the signal strength to preserve/enhance the video signal quality.
Signal Amplification for signal reliability and long length signal
transmission. Our 5V power adapter supplies adequate power to amplify the
video signals from different video sources. This is necessary as the overall
length from the video source to the displays is longer when using the
switches(distance from the video source to the switch + distance from the
switch to the display). In most cases, the overall distance that the HDMI signal
will need to travel is over 10ft. Due to the nature of HDMI signals,
amplification is necessary to warrant the video quality and reliability. (Without
amplification, there may be occasional blackouts or blinking effects) With this
amplification feature, your video display can be extended up to 330ft using
our fiber optical HDMI cables.
Compact and Practical Design
Our switchers have all of the HDMI ports, power supply jack and RS232 port
in the back of the unit allowing it be mounted on any racks or with any other
components. In the front, there will be a remote control sensor, selector
switch, RS232 LED indicators and channel indicators.
Remote Control Unit with Discreet Channel selections
Remote Control Units with discreet channel selection feature is included in all
our switches. The channel buttons on the remote control unit will allow you to
change video sources easily and quickly.
RS232 Control
Our switches also feature RS232 Control. Our switches are capable of being
controlled by a remote computer. This is extremely helpful for many
applications where you need to automatically switch the video inputs.
Example: If you connect a PC to our switcher, you can program it to
automatically switch the sources. If you want to display input 1 for 1 hour and
then switch to input 2, you can do this with the PC. The RS232 LED indicators
in the front will allow you to check the communication between the PC and the
switch. Most other products require additional control box for this function.

(Control software not included)
**RS232C Control Command with HDS-21R//41R Switcher
RS232C interface the HDS-21R/41R switcher with a serial port on a
control computer or other remote control devices.
Our HDS-21R and HDS-41R use pin#2 and #3 and the assignments are as follows;
Baud Rate : 9600bps
Control computer's RS232 pin# 2 is connected to our HDMI switcher's pin#3
Control computer's RS232 pin# 3 is connected to our HDMI switcher's pin#2
The control protocols are as follows;
Channel 1 request is ASCII code "@001*" and the response back to the computer is "!"
Channel 2 request is ASCII code "@002*" and the response back to the computer is "!"
Channel 3 request is ASCII code "@003*" and the response back to the computer is "!"
Channel 4 request is ASCII code "@004*" and the response back to the computer is "!"
