14、RS-232C Control Specification Page: 5 / 14 Document Version 1.01 Company Restricted 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 statu

Start character : Request status : see “Status request list” Request character : ? End character (CR) : 0Dh 3-2-2. Transmis

16、sion 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

17、 : , ACK : 06h, End character (CR) : 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 3-2-2-2. Form2: Status answer and Auto status feedback Status answers are reply

18、data when Slave got an acceptable Request status or Command data from Host. Auto status feedbacks are sent to Host data when a Slaves status is changed. Start character : Answer character : see “Status list” End character (CR) : 0Dh A ACK 06h CR 0Dh start A NAK 15h CR 0Dh start start command “xxx:”+

The transaction sequences and the regulations 3-3-1. The transaction sequences The transactions ha

20、ve 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 Slaves status chang

21、ed. (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) transmission from the Slave has to finish within 500ms when got a Command or a Status request from Host. * Host must not transmit a

22、n another Command or Status request until it receives a answer by a previous Command or Status request or it passes a term of waiting 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 d

23、ata. 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 is assigned most kindly status to Host. (The statuses of layer 2 are assigned kindly status,

24、 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

25、is changed and if the status feedback is enabled. * The product defined and segmentation layers are taking in status list. 3-3-4.
