[Range] (pL+pH×256)=4(pL=4、pH=0)
m=48
fn=64

[Outline] [The specification which is common to the model]
Sends the key code list of defined NV graphics.
• When key code list is present
Hex. Decimal Data Size
Header 37H 55 1 byte
Identifier 72H 114 1 byte
Status 40Hor41H 64or65 1 byte
Data 30H~39H 48~57 2~ 80 bytes
NUL 00H 0 1 byte
• When key code is not present
Hex.
Decimal Data Size
Header 37H 55 1 byte
Identifier 72H 114 1 byte
Data 40H 64 1 byte
NUL 00H 0 1 byte
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.
