4.9.3. SIO(RS232) Special Commands
0xF2F10018
Auto-Sync Mode control register
Bit 31 : auto sync enable
Bit 30 : SIO enable mode (0 : Custom mode, 1 : IIDC v1.31)
Bit 27 : auto sync complete (read only. 1: ready, 0: not yet auto-sync)
Read/Write
Custom commands are valid when the Bit30 is to be set “0”(zero).
SIO(RS232) custom commands are non IIDC compliant which is a specific mode for the cameras.
Before using these commands serial communication parameters must be set at Serial_Mode_Reg(F2F22000h)
F2F10018 means that the RS232 command is valid.

Command format : [STX] [Command] [Data] [ETX]
[STX] : Command start character : ‘S’
Command] : Command length is 2byte. See next page command table.
[Data] : Data length is varied with each command. Data format is hexadecimal: ‘0’~’9’, ‘A’~’F’.
[ETX] : Command end character : ‘Z’
Return value
‘G’ : Command complete acknowledge.
“Gdd..d” : “dd..d” is return data and hexadecimal character.
‘U’ : Undefined command.
Valid Character: ‘0’~’9’, ‘A’~’F’, ‘S’,’Z’ Invalid character is received is discarded.
Example: Gain setting command with 0x200 value.
All of “SA0200Z”, “S A0 200 Z”, “SA0 200Z” , “S A0200 Z”, and “SKA0V200Z” are parsed to
“SA0200Z Z”, and “SKA0V200Z” are parsed to “SA0200Z”.
