CT-HDVD-HDCX-IR
This HDMI over RF extender utilizes RF conversion technology to convert an
HDMI signal to an HD digital TV signal, and transmits it by coaxial cable up
to 700 meters. It provides a high quality image and anti-interference
capability and can be used with a CATV splitter to realize one to many, many
to many, and video matrix operations.
The HDMI extender can be applied to a wide variety of operations, such as
CCTV monitoring, large outdoor screens, shopping malls, education, digital
KVM fields, etc.
1. Cable length is suggested to be between 300 & 700 meters. If the cable
is shorter than 100 meters, a signal attenuator of at least 20db will be
needed. Choose an attenuator size which provides proper signal level at the
TV.
2. Refer to appendix 1 for channel-frequency mapping table; refer to
appendix 2 for coaxial cable signal loss values for each channel frequency.
3. When using a CATV splitter for 1-to-many and many-to-many operation,
please use a bi-directional splitter with low insertion loss, high shielding and
a frequency range of at least 5 ~ 1000Mhz
The IR remote is used solely to change the receive channel of the RX
device at the TV. For example, if there is a Playstation on channel 1, a
Blu-Ray player on ch 2 and a Satellite receiver on channel 3, use the
remote to choose ch1 to see the playstation, ch2 for the Blu-Ray etc.
*This channel selction is for the receivers only, and is not passed across the
coax to the transmitter(s).
75Ω
There are 100 channels (0~99), selected with 2 buttons. The left
button changes the‘singles’digit (on the right) and the right
button changes the “tens”digit (on the left). For eaxample, to set
channel “21”, press the right button until the left digit is “2” and
press the left button until the right digit is “1”. Connection
between a TX device and an RX device is only possible when both
devices are set to the same channel.
