RS-232C

(3) Receiving format (VTR computer)

The VTR responds to a send command with the format data below.

1.First, the VTR returns the data indicating whether the command from the computer was received properly.

1)If the communication was error-free, the VTR returns the ACK (Acknowledge) data.

[ACK]

06H

2)If there was a problem in communication, the VTR returns the data starting with NAK (Negative Acknowledge).

If the VTR was in the process of sending the data when the computer sent its command, the VTR returns NAK after it completes the sending of the data.

The VTR now destroys all the received data with errors.

[NAK] ) 15H (XX)

OContents of )

1 (31H): Parity Error

3 (33H): Framing Error

4 (34H): Over Run Error

2.Next, after ACK is returned when the communication was error-free, the data is returned in the following format by the operation of the VTR.

1)The format of the response (return) data in cases where commands from the computer were properly received by the VTR is as follows.

[STX] [data] [ETX] 02H XX.....XX 03H

example:

Send command Return data = Receive data [STX] QOP [ETX] [ACK] [STX] OEJ [ETX]

[STX] QCD [ETX] [ACK] [STX] CD )))))))))) [ETX]

2)If there were errors in the data or any problems in the VTR, a description of the reason why the data was not received is returned in the following format.

[STX]	E	R	0	0	)	[ETX]
02H	45H	52H	30H	30H	XX	03H

OContents of )

1 (31H): A command which is not supported or a command execution error

2 (32H): Erroneous parameter with the wrong data code

3 (33H): Receive buffer overflow error

[STX]	E	R	1	0	)	[ETX]
02H	45H	52H	31H	30H	XX	03H

OContents of )

2 (32H): Front loading error

3 (33H): Loading error

4 (34H): Drum capstan system error

5 (35H): Reel system error

6 (36H): Tension system error

7 (37H): Fan motor error

8 (38H): Dew error

[STX]	E	R	1	2	)	[ETX]
02H	45H	52H	31H	32H	XX	03H

OContents of )

0 (30H): Search error (start/end)

1 (31H): Search error (search aborted by front panel operation)

2 (32H): Search error (no target position)

3 (33H): Search error (search aborted by command)

[STX]	E	R	1	F	F	[ETX]
02H	45H	52H	31H	46H	46H	03H

System (servo communication) error

<Note>

Check the operation carefully before use when controlling the VTR from a personal computer, etc.

It is recommended to monitor VTR status information while controlling the VTR in this way.
