6.2 How to Request Error Message Output
If an error occurs when the host sends a setting or control command to a VR200
recorder via the RS-422-A communication interface, the host can request the VR200 to
output an error message.
(1) Error message (error number) request command
ESC S (C
R
) (L
F
)
(1B)H (53)H
(2) Error message sent from VR200 in reply to ESC S command
Output format: ERxx (C
R
) (L
F
) (xx = 00 to 10. See Section 2.4.2 for details.)
Note
An error message is output only when the ESC S command is sent.
If the ESC S command (request for error message) is sent to a VR200 while data is being output due to the receipt of a TS0, TS1
or TS2 command, a communication error may occur.
When data is exchanged between the host and a VR200 via RS-422-A communication, it is possible to monitor the errors during
each transmission and reception by assembling the ESC S commands in the communication program in the host computer.
