D-TUNE Installation Manual
7
The RGBHV/YPbPr port is meant primarily for VGA, 480i and 480p. While it can handle up to XGA the
image will be downscaled to 480p which may not be desirable in some situations.
Different views of the D-TUNE:
6.2 RF connectors
The coaxial connector (ANT) of D-TUNE is RF signal input – either aerial or cable TV, UHF/VHF, if the
D-TUNE shall be used as TV tuner. The other is for FM antenna reception.
6.3 Power connector
Connect the supplied 12v DC adapter to the power jack of the D-TUNE unit.
Note that depending on pre-programmed settings the D-TUNE can switch on automatically upon
attaching power supply, or remain in a “sleep” state.
It is recommended to connect the power supply only after all other connections are done.
7 Operating the D-Tune
The D-TUNE has many advanced features to enhance the typical viewing and usability of a TV Tuner.
A user can switch the unit on or off, control volume level, switch the current TV channel, either directly
entering channel number, or browsing through valid channels using Channel +/- keys (usually Arrow
Up/Down key on a remote controller). “Valid” channels are the channels where a valid TV signal was
discovered during recent “channel scan” operation (in stand-alone mode).
Since the D-TUNE allows to attach several additional video signal sources to its AV inputs, to facilitate
user selection of these inputs D-TUNE maps some additional “channel numbers” to its AV inputs. So
when a user selects one of these “channels”, the D-TUNE switches to the respective AV input. These
reserved channel numbers are based on the values selected in the service menu and could be setup in
many different ways as shown below.
26 - Composite video IN (Default is 126)
97 - S-Video IN (Default is 127)
108 - RGB+HV IN (Default is 128)
2 - YPbPr IN (Default is 129)
When a user changes to one of the channels above the appropriate input will display instead of the normal
TV channel signal.
Note that RGB and YPbPr inputs actually share the same connection (15-pin female VGA-like), so
channels 128 and 129 change only interpretation of this input. For instructions on selecting or changing a
“channel” for an assigned input, please see section 7.6 “Map A/V Input to Channel”
More advanced functionality differs in different operating modes, which is described in more detail below
and in the subsequent chapters of this document.
