20.0D : DMC START : DMC=Dynamic Motion Control (=VAR MEMORY)
This command is used to run the DEVICE from the present tape position at the speed that is
stored by the “20.4B : DMC RUN” command.
20.0F : EJECT
When receiving this command, the DEVICE ejects the cassette.
20.10 : FAST FWD
20.20 : REWIND
When receiving this command, the DEVICE will become the specified mode.
2X.11 : JOG FWD
2X.12 : VAR FWD
2X.13 : SHUTTLE FWD
2X.21 : JOG REV
2X.22 : VAR REV
2X.23 : SHUTTLE REV
When receiving one of the above commands, the DEVICE will start running in accordance with
speed data defined by the DATA-1 and the DATA-2.
When only DATA-1 is given, (X=1) and the tape speed will be defined as follows.
TAPE SPEED=10
(N/32-2)
, N : SPEED DATA (DECIMAL)
Example)
TAPE SPEED SPEED DATA
STILL 0 (0H)
0.1 times normal speed 32 (20H)
1.0 times normal speed 64 (40H)
About 2.9 times normal speed 79 (4FH)
When setting more precise value than the tape speed defined by DATA-1, DATA-2 will be
added, however, the precise value is a linear approximate value. (X=2)
When both DATA-1 and DATA-2 are given, the tape speed will be defined as follows.
TAPE SPEED=10
(N/32-2)
+ N’/256 {10
[ (N+1)/32-2]
_ 10

N’: SPEED DATA OF DATA-2 (DECIMAL)
20.30 : PREROLL
When receiving this command, the DEVICE will be prerolled to the tape position, that is, the
value obtained by subtracting the time defined by the “44.31 : PREROLL TIME PRESET”
command from the IN POINT data equivalent to the TIMER DATA or TIME CODE stored in
the IN ENTRY memory by the “40.10 : IN ENTRY” command.
24.31 : CUE UP WITH DATA
This command is used for cueing up the DEVICE to the position assigned by the time data of
DATA-1 through DATA-4.
A unit of respective data are as follows :
