.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.

.0F : EJECT

When receiving this command, the DEVICE ejects the cassette.

.10 : FAST FWD

.20 : REWIND

When receiving this command, the DEVICE will become the specified mode.

.11 : JOG FWD

.12 : VAR FWD

.13 : SHUTTLE FWD

.21 : JOG REV

.22 : VAR REV

.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)

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’: SPEED DATA OF DATA-2 (DECIMAL)

.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.

.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 :
