9.2 Communication protocol
This camera uses the communication protocol of our standard method (where, parameters are set for the
camera-internal registers).
In command transmission/receipt, the address and data in hexadecimal representation are converted to ASCII.
In addition, all alphabetical characters must be uppercase characters.
(1) Writing to the register
To write data to a register, send a write command as follows.
STX (0x02)
Data Upper
Address Lower
Address Upper
Data Lower
ETX (0x03)
For example, to write data 0x38 to address 0x64, send a write command as follows.
STX (0x02)
"3"(0x33)
"4"(0x34)
"6"(0x36)
"8"(0x38)
ETX (0x03)
The camera responds to the write command as follows.
STX (0x02)
ACK(0x06)
ETX (0x03)
STX (0x02)
NAK(0x15)
ETX (0x03)
*When you let camera operation reflect the changed register setting, Please you write in address 0x6E at 0x01
by all means, and update it.
(2) Reading the register
To read data from the register, send "R "Q" following the address.
For example, to read data from address 0x6A, send a read command as follows.
STX (0x02)
"R"(0x52)
"A"(0x41)
"6"(0x36)
"Q"(0x51)
ETX (0x03)
The camera responds to the read command as follows.
STX (0x02)
Data Upper
Data Lower
ETX (0x03)
