HDbridge 2840 Configuration Guide
|
Page 5
Factory default settings allow HDb2840 units to broadcast
up to 4 unencrypted HDMI sources on RF channels 2, 3, 5,
and 6 for reception at connected HDTVs.
We recommend using the most updated version of
firmware. You can find the latest version on the Support
section of our website.
Beginning setup
1.
Apply power.
2.
Connect an HDMI video source to the HDMI input port
of the HDb2840, using an HDMI cable (which is sold
separately). For Closed Captioning, connect a composite
(yellow) cable from the video source to the Caption port.
3.
Optional
– Connect the Analog Audio if the digital audio is
not present on HDMI or if you want to implement the delay
matched audio feature.
Tuning your channel at the HDTV (Auto Scan)
1.
Connect the Coaxial Output of the HDb2840 to your
RF network.
If the RF power for your network is too high, you will
observe video breakup.
2.
Specify Cable (not Air or Antenna) setting in your TV menu.
3.
Enter the RF number to tune directly to the channel. For
default channel lineup information, refer to the Default
Channel Lineup table.
If you cannot tune directly to
the channel at this point, it is
because most TVs will require
you to run a full Auto Scan.
4
. Run the Auto Scan through
the menu system of your
HDTV to find the channels.
