RTS → CTS
CTS ← RTS
TxD → RxD
RxD ← TxD
1. The host checks that CTS is High, then starts a data transmission from TxD.
2. The host performs the data transmission of the number of required bytes, and ends a transmission.
* The host can do RTS to Low during the transmission for disable dat a transmission from a slave.

3-2. Transmission data format
3-2-1. Transmission data format from Host to Slave
There are two kinds of transmission data form from Host shown below .
3-2-1-1. Form1: Command
Command is a data that requests some status change.
Start chara cter : ’@’
ID : ‘0’ ~ ‘9’ (A Slave has ow n ID, A Host has to set the ID.)
COMMAND : see “Command list”
End character : 0Dh

3-2-1-2. Form2: Status request
Status request is a data that requests a answer of some status.
Start chara cter : ’@’
ID : ‘0’ ~ ‘9’ (A Slave has ow n ID, A Host has to set the ID.)
Request character : ‘?’
Request status : see “Status request list”
End character : 0Dh

3-2-2. T ransmission dat a format from Slave to Host
There are two kinds of transmission data form from Slave shown below .
3-2-2-1. Form1: ACK/NAK
ACK is a reply data from Slave when Slave got an acceptable command data from Host.
ACK : 06h
ACK
06h
NAK is a reply data from Slave when Slave got an incorrect Command data, Status request data or
some other data from Host.
NAK : 15h
NAK

3-2-2-2. Form2: Status answer
Status answers are reply dat a when Slave got an acceptable Re quest status data fro m Host.
Start chara cter : ’@’
ID : ‘0’ ~ ‘9’ (A Slave will set own ID.)

3-3. The transaction sequences and the regulations
3-3-1. The transaction sequences
The transactions have two kinds of sequence.
*A transaction is a Command from Host then the Sla ve will be an answer by ACK or NAK.
*A transaction is a S t atus request fro m Host then the Slave will be an an swer by Status answer.
3-3-2. The transaction regulations
The transactions have some kinds of regulation.
* A Command or a Status request transmission by the Host has to finish within one second.
* An answer (ACK , NAK or Status answer) transmitt ion by the Slave ha s to finish withi n one second
when got a Command or a Status request from the Host.
* The 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 one second from a finishing of previous transmission
of a Command or a Sta tus request ".
