3 Configuration
The board can be configured both manually and through the Network control system
Multicon GYDA. Only a subset of the user-configurable parameters is available when
operating in manual mode.
3.1 Manual mode
To reach manual mode DIP24 labeled OVR on the board must be switched on (to the
right in Figure 2) and the board must be re-booted. This takes the board out of Multicon
GYDA control (if the DIP was previously set to off) and into manual control by the DIP
switches and rotary switch. Parameters not controlled by any of these switches are
kept unchanged from previous session (factory default or Multicon GYDA setup).
The Manual mode configuration controls are all found on the front side of the board.
There are three sets of eight DIP switches each, one rotary switch and two push
buttons. The slide switch on the lower right side is set for all modes of operation.

3.1.1 Rotary switch and push buttons
The rotary switch, labeled DLY, adjusts the phase delay from -5 to +4 video lines. The
switch 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 front of the frame when the module
is installed.
The push buttons, labeled INC and DEC, are used to fine adjust the phase delay by
samples. They can adjust the phase delay within +/- ½ video lines for the present video
standard.
3.1.2 Factory reset function
A factory reset sets all parameters of the module back to the state they were in when
the module left the factory. These settings are just a starting condition for the module,
and all subsequent changes by the user will still take effect and be stored.
The factory reset is done by setting the DIP marked F-RESET and OVR both to the on
position, and powering up the module. The inputs should be removed. Then the
module has to be pulled out of the frame (or power to the frame removed), before the
DIP marked F-RESET is put back to the off position and the module powered up again.
The card will then reset. The board must remain powered for at least 10 seconds for all
the factory values to be stored properly.
