2-2. Transmission data format
2-2-1. Transmission data format from Host to Slave
There are two kinds of transmission data form from Host shown below.
2-2-1-1. Form1: Command
Command is a data that requests some status change.
Start character : ’@’
COMMAND : see “Command list”
End character (CR) : 0Dh
start
‘@’
2-2-1-2. Form2: Status request
Status request is a data that requests a answer of some status.
Start character : ’@’
Request status : see “Status request list”
Request character : ‘?’
End character (CR) : 0Dh
start
‘@’
2-2-2. Transmission data format from Slave to Host
There are two kinds of transmission data form from Slave shown below.
2-2-2-1. Form1: ACK/NAK
ACK is a reply data from Slave when Slave received an acceptable command data from Host.
(ACK is sent to Host when Slave has no related status by the Command.)
Start character : ’@’, ACK : 06h, End character (CR) : 0Dh
‘
@
NAK is a reply data from Slave when Slave received an incorrect Command data, Status request data
or some other data from Host.
Start character : ’@’, NAK : 15h, End character (CR) : 0Dh
2-2-2-2. Form2: Status answer and Auto status feedback
Status answers are reply data when Slave got an acceptable Request status or Command data from
Host. Auto status feedbacks are sent to Host data when a Slave’s status is changed.
Start character : ’@’
Answer character : see “Status list”
End character (CR) : 0Dh

2-3. The transaction sequences and the regulations
2-3-1. The transaction sequences
The transactions have three kinds of sequence.
*A transaction is a Command from Host then Slave will be an answer by Status answer, ACK or NAK.
*A transaction is a Status request from Host then Slave will be an answer by Status answer or NAK.
*A transaction is Auto status feedback from Slave when a Slave’s status changed.
2-3-2. The transaction regulations
The transactions have some kinds of regulation.
* An answer (ACK, NAK or Status answer) transmittion by Slave has to finish within 500ms when got a
Command or a Status request from Host.
* Host must not transmit an another Command or Status request until "it receives a answer by a
previous Command or Status request" or "it passes a term of waitinng time from a finishing of previous
transmission of a Command or a Status request ".
* Slave has to finish a transaction under 500ms when it sends Auto status feedback data.
2-3-3. Specification of Auto status feedback
There are some specific regulations about Auto status feedback.
* Slave sends auto status feedback by itself when the status is changed.
2-3-4. Example of the transactions

3. Recommendations of Command, Status and Layer definition
- ‘ACK’ means that a slave has received an command. If a slave can receive a command properly, the
slave sends a Host a Status data.
4. Definitions of Command, Status and Layer
This section discribes the definition of “Command”, “Status Request” and “Status” commands of this product.
