Teac SX-1:SX-1LE Documentation Sony P2 Protocol - Manual (Page 8)

If there is no valid VIDEO or TTL signal being received by the SX-1, then the command
will be executed during field 1 of the calculated frame. The frame boundaries are
assumed to line-up with the first sample at 00:00:00:00
If another command (deferred or not) is received while there is a command pending, then
the pending command is executed straight away, and the next incoming command is
processed. If the new command is also deferred, it will be marked for pending execution.
If the transport stops moving while there is a command pending, the command is executed
immediately.
When the EDIT ON command is received, the SX-1 Auto-punch Rehearsal function is
automatically turned off, and the HDR performs a punch in record.
When the SELECT EE ON command is received, the SX-1 Auto-punch Rehearsal function
is turned on, and the HDR simulates a punch-in record.
When the EDIT OFF command is received when the SX-1 is recording, the SX-1 will punch
out of record.
*7 SYNC PLAY: The SX-1 will ignore the data supplied in the command and will just start
playing. Frame settings must be made using the Clock and Video resolve modes separate
from the P2 Slave.
*8 PROGRAM PLAY: This does not imply any video or frame resolution, it is just a different
way of specifying the shuttle speed.
Calculated speed = N /10 percent of play speed, where N is the first data byte.
For PROGRAM PLAY FAST, this calculated speed is added to normal speed, i.e. the range
of control is 1x (DATA=0) to 1x plus 25.5% (DATA=FF) = 1.255x
For PROGRAM PLAY SLOW, the range is 1x (DATA=0) to 1x minus 25.5% (DATA=FF) =
0.745x
As in note *5, the actual resolution of the SX-1 playback is 1/1024 normal play speed, and
the current play back speed smoothly ramps between the current speed and the requested
speed, updating every 1024 samples.
