LIS-SDI card will enter programming mode. This causes no harm, but the card will not work
in this mode.
Factory setting is switch 10 in
on
position.
Switches 5, 6, 7 and 9 - Reserved
These switches are reserved for future expansion, and should always be in the
off
position.
Factory setting is switch 5, 6, 7 and 9 in
off
position.
Switch 8 - Reset to factory default
LIS-SDI contains EEPROM that is affected by your choices. Switch 8 is implemented to reset
the EEPROM to factory default. Its use is shown in Table 2.
Action Comment
Power down.
Turn switch 8
on
.
Power up.
LIS-SDI enters a special state where the EEPROM is restored to factory default
values. This is flagged by the LEDs, they are all yellow.
Power down.
Turn switch 8
off
. If you want the DIP switches to be placed in the factory default position, this is the
time to do so: Turn switches 1 through 9 to the
off
position. Switch 10 should, as
always, be turned to the
on
position.
Power up.
The card EEPROM is now reset to factory settings.
Table 2: Method to restore the LIS-SDI card to factory settings.
Remember to let some seconds pass by each time you power down, to allow capacitors to be
fully discharged.
Switch 1 - Manual mode
Switch 1 is the manual mode switch. If
on
, the LIS-SDI is primarily assumed to be operated
with switches alone. If
off
, the LIS-SDI is assumed to be used with a GYDA controller.
Factory setting is switch 1 in
off
position.
With switch 1 off
While in automatic mode, switches 2, and 3 are without any effect.
With switch 1 on
In manual mode, the functionality of switches 2, and 3 is as follows:
Switch 2
Switch 2 turns on/off disabling of EDH in the output SDI. With switch 2
off
, the EDH is
included in the SDI signal, with switch 2
on
, EDH is not included.
Factory setting is switch 2 in
off
position.
Switch 3
Switch 3 turns on/off the line sync mode. With switch 3
off
, the video output is delayed half a
line with respect to the first SDI input detected. The LIS-SDI tolerates upstream video
switching on the input SDI. The deglitching only works if any of the different SDI inputs has
a phase difference not more than half a line from any of the other SDI inputs that will be used
with the LIS-SDI.
