When both Read and Write LEDs are blinking, SMPTE Regenerate
mode is selected and the box is waiting to acquire incoming
SMPTE. This mode is selected by setting the “Regen” dip switch
ON. When the “Regen” dip switch is set ON, SMPTE Write is dis-
abled. Once locked to the incoming SMPTE, the Regenerate LED
pair blinks in the same manner as the Read LED blinks in SMPTE
Read mode.
In Write mode, the SMPTE format always matches the format set
up on the SMPTE Format DIP switches. These DIP settings affect
Write mode only. On the other hand, when SMPTE is being Read
or Regenerated, the output format is always the same as the input
format. Automatic format detection will take between 3 and 31
frames, depending on the incoming format and the value of the
first SMPTE frame received. When using the PORTMAN with a
sequencer program synced to MIDI Time Code, at least 5 seconds
of pre-roll (always a good idea, anyway) are recommended for
proper synchronization.
In Patchbay mode, SMPTE can only be regenerated or written. In
interface mode, SMPTE can be read, regenerated or written.
