Note that three special conditions also exist:
When all four LEDs blink synchronously, this is the result of a locate on
command. This condition will eventually time out, but can also be reverted by
issuing the locate off command.
The second special condition is when an FPGA firmware upgrade is performed:
When Multicon GYDA is finished transferring the compressed data file, the card
will spend some time unpacking this file and during this time it will not respond to
commands or update settings. During this time it will display running lights (three
LEDs lit, one dark, the position of the dark LED will move around).
The last special condition is when the user adjusts the phase delay with the push
buttons at the front of the card. Short flashes on the SYNC or INPUT LEDs
means that the end of the adjustment range has been reached. If they flash
simultaneously, both push buttons have been pressed simultaneously and the
samples part of the phase delay reset to the middle of the adjustment range.
