3–4 • User Controls HDC-8222A User Manual (Iss. 02)
Remote Control Enable (S1.1)
This switch enables the remote control interface as follows:
•
ON
— Select this setting to control the HDC-8222A using the DashBoard Control
System. This also disables switches
S1.2
through
S1.8
. Control can be either from the
remote control (such as DashBoard), or these card-edge switches, but not both.
•
OFF
— Select this setting the remote control cannot set any card parameters, but can still
monitor the status of the card.
Aspect Ratio Control (S1.2 to S1.5)
These switches control aspect ratio for both HD and SD inputs separately. Refer to Table 3.1 for
the positions to select various preset or user defined aspect ratios.
Underscan (S1.6)
This switch activates an underscan feature, further reducing a selected aspect ratio by 10%.
Analog Composite Color (S1.7)
This switch enables or disables color on the SD analog output.
Field Lock (S1.8)
This switch enables or disables the Field Lock feature on the HDC-8222A. The Field Lock
feature is used to ensure that the output SD signals have the correct field polarity when 720p
59.94Hz and 720p 50Hz signals are used as the input.
• There is no information in the 720p signal that indicates which frames should be made
into even fields and which should be made into odd fields.
• The Field Lock feature looks at the frame reference bus and makes sure that the output
field polarity matches that of the reference bus.
• If the aspect ratio has been adjusted off of the default setting, do a factory restore to
correct it.
Note
— With DashBoard connected, and to avoid user setting override when
switching from Local to Remote control, it is recommended to save your card
settings, set S1.1 to ON , and then reload the card settings from DashBoard.
Note
— When switching from Remote to Local control, switches S1.2 to S1.8 will
override some user settings made in DashBoard.
