Power Supply Connector
A 12V DC power supply is connected here to provide power to the unit.
Power Indication LED
This LED lights up GREEN to indicate that the unit is receiving power.
Signal Lock Status LED
This LED lights up GREEN to indicate that the
HD-SDI
input signal is "locked". The LED lights up AMBER to indicate
an unlocked signal. The LED remains unlit if no source is attached to the input.
Option DIP Switches (1 and 2)
These two 10-position DIP switches modules (
1
and
2
) are used to set the available options for the
HD2SD
. For detailed
information about the available options and how to set them, see details starting on page

HD2SD Settings - DIP Module 1 and 2
The various options are selected by setting the switches on
DIP Module 1
and
DIP Module 2
.
DIP Module 1
is used to set the analog output type (converted from the down-converted SD signal), SD pedes-
tal, graticule type, center cross, embedded audio resolution, video anti-alias filter, and down-converter output
format.
DIP Module 2
operates in two selection modes;
Video/Audio Options
mode and
Video Test Pattern
mode.
When switch
9
of
DIP Module 2
is in the
UP
position, it is in
Video/Audio Options
mode and is used to set the
down-converted aspect format, SD raster output and graticule aspect ratio, EDH, and audio test tones. When
switch
9
of
DIP Module 2
is in the
DOWN
position, it is in
Video Test Pattern Mode
is used to select video test
patterns for output.
DIP Module 2
also features two refresh modes as set by switch
10
;
Update Mode
and
Update Pause Mode
. In
Update Mode
the DIP switch is continuously monitored for changes to its settings and so the unit will update it’s
function at the first detected switch change. When making multiple switch settings, the user should place the unit
into
Update Pause Mode
by setting DIP Switch
10
into the
DOWN
position. This pauses the updating of the
DIP switch settings. When the desired multi-switch setting has been made, the unit should be placed back into
Update Mode
by placing DIP Switch
10
into the
UP
position so that the new setting configuration can be read
and enabled by the unit.
See the procedures for the selection modes in the following pages for more information on how to use the refresh
modes.
