RS-232C
(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
02H
45H 52H
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.
