Card Control and Status
The card can be configured and monitored in two ways:
1) Via DashBoard remote control software. Dashboard remote control software is the subject of
chapter 3.
2) Via LEDs and switches on the front edge of the card
Switch S1, located on the upper card edge, controls the primary functions of the card. ON is defined as
the switch in the “UP” position, away from the board. OFF is defined as the switch in its “DOWN”
position, towards the board.
Switch S1
Switch S1 is located on the upper card edge and controls the primary functions of the card. ON is
defined as the switch in the “UP” position, away from the board. OFF is defined as the switch in its
“DOWN” position, towards the board.
S1.1 -- Remote Control Enable
S1.1 enables the remote control interface. If S1.1 is set to ON the user can control the UDC-163 card
using Dashboard remote control software. Setting S1.1 to ON, disables switches S1.2 through S2.8.
Control can be either from remote operators, or these card edge switches, but not both.
If S1.1 is set to OFF, the remote control cannot set any card parameters, but can still monitor the status
of the card.
S1.2 through S1.5 – Aspect Ratio Control
These switches will control aspect ratio for both HD and SD inputs separately. See Table 2 for the
positions to select various preset or user defined aspect ratios.
S1.6 – Underscan
S1.6 will activate an “underscan” feature, further reducing a selected aspect ratio by 10 percent.
S1.7 – Analog Composite Color
S1.7 will enable or disable color on the SD analog output.
S1.8
– Field Lock
S1.8 will enable or disable the field locking feature on the card. Field lock is used to ensure that the
output SD signals have the correct field polarity when 720p59.94 and 720p50 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.
