2. Global Description
2-1. Overview
A Host controller can control or watch out the product as a Slave very easily via the communication cable.
2-2. Block Diagram
* The product connector is using D-SUB 9pin male.
* RS232C cable must use D-SUB 9pin female to connect the products.

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 character : ’@’
COMMAND : see “Command list”
End character (CR) : 0Dh
Start
@
Command
“xxx:”+”...”
End
0Dh
3-2-1-2. 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
@
Command
“xxx:?”+”...”
End
0Dh
3-2-2. Transmission data 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 is sent to Host when Slave has no related status by the Command.)
Start character : ’@’, ACK : 06h, End character (CR) : 0Dh
Start
@
ACK
06h
End
0Dh
NAK is a reply data from Slave when Slave got an incorrect Command data, Status request data or
some other data from Host.
Start character : ’@’, NAK : 15h, End character (CR) : 0Dh
Start
@
NAK
15h
End
0Dh
3-2-2-2. 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 send to Host data when a Slave’s status is changed.
Start character : ’@’
Answer character : see “Status list”
End character (CR) : 0Dh
Start
@
Status
“xxx:”+”...”
End
0Dh

3-3. The transaction sequences and the regulations
3-3-1. 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. (If the auto status
feedback is enabled.)
3-3-2. 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.
3-3-3. Specification of Auto status feedback
There are some specific regulations about Auto status feedback.
* The product status has segmented into four layers of 1, 2, 3 and 4.
* The status of layer 1 are assigned most kindly status to Host. (The statuses of layer 2 are assigned
kindly status, the statuses of layer 3 are not so need status to Host and the statuses of layer 4 are
probably no wished statuses.)
* Each layer status can control transmit enable or disable by Host command. (The product default
would be all disables.)
* Slave sends auto status feedback by itself when the status is changed and if the status feedback is
enabled.
* The product defined and segmentationed layers are takeing in status list.

4. Recommendations of Command, Status and Layer definition
-All Commands, Statuses and Layers will be defined other specific document.
-[MANDATORY] The product MUST have Commands and the Statuses same as a remote controller
buttons (IR controller) of the product.
-All Commands are required working by discreate as ON/OFF commands. (It means that do not support
TOGGLE command only. )
-All Commands and Statuses are defined same chharacter size except ACK/NAK on the product.
( Recommended character length : 3~6 characters )
-It permits attaching 0x0A character to a reply characters from the product. In this case, must suppose that the object
is followed altogether.
-Recommend to supports numbers or values direct setting command, if it has variable numbers or
values.
5. Definitions of Command, Status and Layer
