10. OPTIONAL SA-K97U RS-232C INTERFACE BOARD
2-4 Others (Input data correction/Error cancellation)
These are return codes from the SR-9168U. (Error-related codes only)
(1)
ERROR (02H)
: This is returned when commands of more than 1 byte are transmitted to the VCR and an illegal command is
received in the 2nd byte (or later) of the transmitted command.
In this status, no command can be accepted and only STATUS SENSE will be returned.
To restore normal operation, transmit CLEAR ERROR (41H) or CLEAR (56H) to the VCR.
CLEAR ERROR (41H)
: Used to cancel previously-transmitted 1-byte numeric data when inputting
numeric data such as an Index search point. Also used to cancel error status.
CLEAR (56H)
: Clears the whole command. Cancels the current status and stops the VCR. Also
cancels the error status.
Eg : After setting the recording/playback mode to “L18H”, 32H is mistakenly transmitted . Cancel 32H with
“41H” and input “33H” instead.
(2)
NAK (0BH)
: VCR will return this code when non-defined or non-functional command is received in the 1st byte of the
transmitted command. In this case, it is not necessary to input CLEAR. Check whether the transmitted command
is acceptable to the VCR or not.
