Switch # Function name Function DIPs Comment
16 OVR Off: GYDA mode
On: Manual mode
This DIP is only
read at power up.
OVR is short term
for GYDA override
FACTORY reset function
The factory reset is done by setting DIP 15 to On and power up the card. The inputs
(optical, electrical video and sync) should be removed. Then, pull out the card, put DIP
15 to Off and power up the card again. The card will now reset. The board must be under
power for at least 10 seconds for all the values to reset.
4.1.2 Rotary switch and push buttons
The rotary switch, labeled DLY, adjusts the phase delay by -5 to +4 video lines. It is only
functional when a sync signal, black & burst or tri-level, is present at the sync input. The
rotary switch is accessible from the board front.
The push buttons, labeled INC and DEC, are used to fine adjust the phase delay by
samples. It can adjust +/- ½ video lines for the present video standard.

location of the slide-switches.
4.1.3 Slide switches
The two switches at the top of Figure 10 switch between AES out and Data out. It DC
couples the output signal when in DATA out mode, and AC couples the signal when in
AES mode.
Note that it is also necessary to enable the data output on DIP8 (=Off), or in
GYDA to output embedded data. Switches moved to the right routes out
AES.
The switch on the left card edge switches between backplane sync input and Flashlink
distributed sync (Future feature upgrade of Flashlink frame). Switch moved up routes the
backplane sync to the card.
