RS-232C
$
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.
