5.5. Serial Interface
The Amazon series cameras are equipped with the SIO (Serial input/output). By using the serial interface, the
user can execute commands by writing data in a specific address in the GigE Vision address range. SIO can be
further used as RS232 interface which supports the IMI tech commands.
Please note that “SIO Pass Through” is disabled by default. To enable “SIO Pass Through” please refer to section
5.5.7.
5.5.1. SIO Pass Through Scheme
5.5.2. 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
5.5.3. SIO (RS232) RX Control Procedure
STEP 1. Read RBUF_ST of the Receive Buffer Status Control Register (address : F2F22008h) and
check number of RX data buffered in the camera.
If (RBUF_ST !=0) the RX is Ready or else RX is NOT Ready
RBUF_ST : The number of current data buffered in the camera (Unit : byte)
RBUF_CNT : READ : Remaining RX buffer size
STEP 2. Write number of RX data intended to read from RBUF_CNT of the Receive Buffer Status
Control Register (address : F2F22008h)
RBUF_CNT can be configured by unit of byte.
The value of RBUF_CNT must be smaller than Amazon RBUF_ST.
STEP 3. Read RS232 RX data from SIO_Data_Register (addr. : F2F22100 )
STEP 4. If data is further required repeat from STEP 1
Note that data consist of 32 bit data the data read should
Bit 0 ~ Bit 7: 1
st
Data Bit 8 ~ Bit 15: 2
nd
Data
Bit 16 ~ Bit 23: 3
rd
Data Bit 24 ~ Bit 31: 4

Data
Bit 0: Msb Bit 31: Lsb
5.5.4. SIO (RS232) TX Control Procedure Method I
STEP 1. Check TX buffer size by reading TBUF_ST of the Transmit_Buffer_Status_Control
register(Addr.: F2F220Ch)
