VTR

1.If the LOCAL/MENU/REMOTE switch on the front panel is not at the REMOTE position, it is not possible to exercise proper control using the RS-232C interface.

If any command except a Q (query) command is sent while this switch is not at the REMOTE position, error code ER001 is returned.

2.After one of the following commands is sent, not all commands can be accepted until the processing of the sent command is completed.

OPT, SCP, SCS, SMS, SPT, SRS, SUB, EFE

Commands which can be accepted

OQ (query) commands

OOSP command (STOP)

OOEJ command (EJECT)

Error code ER001 is returned when a command other than one which can be accepted is sent.

$Send command intervals

The AJ-D250 is a multi-microcomputer VTR. For this reason, it takes time (approx. 150 ms) for communication to be performed between the RS- 232C interface microcomputer and system control microcomputer inside the VTR before any processing can be performed by the system control microcomputer inside the VTR.

Therefore, leave an interval of at least 150 ms before sending a command from the computer.
