Dear customer
Thank you for purchasing this product. For optimum performance and safety, please read these
instructions carefully before connecting, operating or adjusting this product. Please keep this manual
for future reference.
The products are designed to make your A/V device use more convenient, comfortable, productive
and cost-efficient.
The HDMI coaxial extender can do digital coding processing for HDMI signal with DTV technology.
The product adopts RF modulation technology characteristic to transmit the Multiple RF signal through
one common coaxial cable (SYV-75/RG59) for long distance transmission without amplification. The
receiver can restore the high-definition video signal and transmit it to the TV or monitor. By adding
DTV network mixer at the RF cable, you can easily achieve many kinds of transmission mode, e.g.
signal split, switch and matrix.
Our devices offer solutions for noise, space and security concerns, data center control, information
distribution, conference room presentation, school and corporate training environments.
INTRODUCTION
FEATURES：
Contains a transmitter (TX) and a receiver (RX). The TX supports a HDMI input and the RX supports
a HDMI output.
Support HDMI resolution up to 1080P/60Hz.
Transmission distance up to 500 meters by SYV-75-5 coaxial cable and no need amplification.
Adding digital TV network mixer in RF cable, can easily achieve many kinds of transmission mode,
e.g. signal split, switching and matrix.
Support 80 channels for option; frequency ranges 139MHz~950MHz.
Products using the broadcast signal transmission mode, only one line can transmit 48 channels of
high-definition video signal at the same time.
The use of digital TV communication protocol, anti interference and error correction capability is very
strong.
Installs in minutes. Analog monitor system upgrade to HD systems can continue to use the original
connector and cable.

Notes:
1. In normal conditions, transmission distance up to 500 meters by SYV-75-5 coaxial cable and no
need amplification. For the high-frequency RF signal haves signal attenuation, signal strength will
become weakened after adding DTV network mixer and multi output.
2. If the signal frequency is high, the transmission attenuation is greater. So choose low channel for
long-distance transmission.
3. When the transmission distance is short (less than 100 meters), because the signal is too strong,
RX may protect and display "NO SIGNAL" to TV. So now you should choose high channel or adding
attenuator in coaxial cable for the signal attenuation.
4. With the channel set and frequency values refer to the table below, and channel selection switch
setting method is as follows:

No. Problem Description Solutions
1 Non-Power-Connected
1. Check if the power adaptor head is truly and correctly inserted the
power socket.
2. Check the power if it is in on status.
2
Display “No SIGNAL”
to TV
1. Confirm the coaxial cables are intact and reliable connection.

choose high channel or adding attenuator in coaxial cable for the
signal attenuation.
3. Confirm the TX and RX channel settings should be the same
4. Check the cable quality. ( Recommend use SYV-75/RG59 coaxial
standard cable)
3
Display “SIGNAL
LOSS” to TV
1. Confirm the HDMI cable of TX is intact and reliable connection.
2. Check the signal source is power on and output normal.
3. Check the HDMI cable quality.
4
Display “RESOLUTION
NOT SUPPORT” to TV
1. Check the signal source output resolution, may be set too high.
2.Confirm whether to support the signal resolution of TV
5
Image mosaic/
Abnormal Picture
1. Confirm the coaxial cables are intact and reliable connection.
2. Confirm the length of coaxial cable is too short or long.
3. Device EDID read error, please reboot.
4. Nearby signal interference, proposals to change the other channel
6 Abnormal sound
1. Check the signal source output audio format is LPCM. Audio
output options of signal source should be set to "Auto" or "LPCM"
