(3) Receiving format (unit 5 PC)

The unit responds to a send command with the following format data.

1. First, the unit returns the data that indicates whether the command from the PC was received properly.

1) In the case of error-free communication, the unit returns ACK (acknowledge) data.

[ACK]

06H

2) If there is an error in the communication, the unit returns data starting with NAK (negative acknowledge character code 15H).

If data is being sent, the unit returns NAK after the data has been sent.

The unit then destroys all the received data with the error.

[NAK] (

15H (XX)

O

Content of (

1 (31H): Parity error

2 (32H): Data overflow error

3 (33H): Framing error

4 (34H): Overrun error

2. After the unit has returned ACK when the communication was error-free, the unit operates as follows to return the data with the following format.

1) The response data (return data) format used when the commands from the PC have been received properly by the unit is as follows:

[STX] [data] [ETX]

02H XX.....XX 03H example:

Send command Return data = Receive data

[STX] QOP [ETX] 5 [ACK] [STX] OEJ [ETX]

[STX] QCD [ETX] 5 [ACK] [STX] CD (((((((((( [ETX]

2) When the data contains errors or the a problem occurs in the unit, the nature of the errors or the reason why the data was not received is returned with the following format:

[STX] E R ( [ETX]

02H 45H 52H XX 03H

O

Content of (

2 (32H) : Cassette up/down error

3 (33H) : Loading error

4 (34H) : Drum or capstan system error

5 (35H) : Reel system error

6 (36H) : Tension system error

7 (37H) : Solenoid error

D (44H) : Condensation error

E (45H) : Command or parameter error

M (4DH) : Non-executable command (in setting menu mode or time adjustment mode)

P (50H) : Search error (at tape start or end)

F (46H) : Search error (search suspended by front panel operation)

T (54H) : Search error (no target position)

I (49H) : Search error (search suspended by command)

O (4FH) : Receive buffer overflow

<Note>

When using a PC to control the unit, check the unit’s operations carefully.

It is recommended that the unit be controlled while simultaneously monitoring its status information.
