5.8. Serial Interface
The Pearl Series cameras are equipped with the SIO (Serial input/output) feature described in the IIDC 1.31
specification. By using the serial interface, the user can execute commands by writing data in a specific address in
the FireWire address range. SIO can be further used as an RS232 interface which supports pass through and IMI
tech commands.

5.8.2. SIO (RS232) Control Setting Procedure
STEP 1. Configuration of Registers Address : F2F22000h
Baud Rate : 9600, No Parity, 1 bit Stop, 8 bit data length
Write : F2F22000h, Data = 050800000h
Value read after write = 050800020h 20 is the buffer of TX and RX
STEP 2. Enable RS232 TX / RX Address : F2F22004h
Write Data : C00000000 : Now RS232 TX / RX port is enabled
