Note that three special conditions also exist: When all four LEDs blink
synchronously, this is the result of the ‘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.
