• When 40 or more key codes are present, they are sent by being divided in unit of 40max.
Status with continuous transmission data group is 41H.
Status without continuous transmission data group is 40H.
• After sending [Header - NUL] , receives a response from the host and executes the next processing
corresponding to the response.
• In case of “Status (with continuous block): hexadecimal number = 41H / decimal number = 65”
Response
Content of Processing
ASCII
Decimal
ACK
6
Sends next data group.
NAK
21
Resends previous data group.
CAN
24
Cancels processing.
• In case of “Status (last block): hexadecimal number = 40H / decimal number = 64”
Response
Content of Processing
ASCII
Decimal
ACK
6
Terminates processing.
NAK
21
Resends previous data group.
CAN
24
Cancels processing.
