5. AxConfigGPIO(): Set GPIO configuration to input or output. If GPIO0
is digital input and GPIO1~7 are digital outputs, the GPIO1[0] value
will be 0x01.
Function BOOL AxConfigGPIO(byte GPIO1[], byte GPIO2[],
byte GPIO3[], byte GPIO4[]);
Arguments All GPIO configuration values for setting are placed in
four 1-byte arrays:
GPIO1[]: The 1-byte array for GPIO0~7 configuration.
GPIO2[]: The 1-byte array for GPIO8~15 configuration.
GPIO3[]: The 1-byte array for GPIO16~23 configuration.
GPIO4[]: The 1-byte array for GPIO24~31 configuration.
Return TRUE: No error.
FALSE: Function fails.
6. AxSetDO() : Set digital output status. If GPIO0 is set to High, the
SetDO1[0] value will be 0x01.
Function BOOL AxSetDO(byteSetDO1[], byte SetDO2[], byte
SetDO3[], byte SetDO4[]);
Arguments All digital output values for setting are placed in four 1-
byte arrays:
SetDO1[]: The 1-byte array for GPIO0~7 output status.
SetDO2[]: The 1-byte array for GPIO8~15 output status.
SetDO3[]: The 1-byte array for GPIO16~23 output
status.
SetDO4[]: The 1-byte array for GPIO24~31 output
status.
Return TRUE: No error.
FALSE: Function fails.
7. AxGetDI(): Get digital input status. If GPIO0 read back is High, the
ReadDI1[0] value will be 0x01.
Function BOOL AxGetDI(byte ReadDI1[], byte ReadDI2[], byte
ReadDI3[], byte ReadDI4[]);
Arguments All digital input values read back are placed in four 1-
byte arrays:
ReadDI1[]: The 1-byte array for GPIO0~7 input status.
ReadDI2[]: The 1-byte array for GPIO8~15 input status.
ReadDI3[]: The 1-byte array for GPIO16~23 input
status.
ReadDI4[]: The 1-byte array for GPIO24~31 input
status.
Return TRUE: No error.
FALSE: Function fails.

Connector Description
CN1~CN4 Digital I/O Connectors
Digital I/O Connectors (CN1~CN4)
CN1~CN4 are JST S10B-PHD-S-S, 2x5-pin p=2.0mm Dip connectors for
digital I/O interface. The AX92904 is equipped with four 8-bit digital I/O
connectors that meet requirements for a system customary automation
control. These digital I/O signals are from two 16-bit PCA9535:
CN1/CN2/CN3/CN4:
Note: Please contact your local vendors if any damaged or missing items. DO
NOT apply power to the module if there is any damaged component.
Jumper Setting
Before applying power to AX92904, please make sure all jumper(s) are in
factory default positions.

Programming Guide
A set of application programming interface (AxDIO32 DLL) functions are
released for users to access/control hardware. With these API functions,
users can more easily design their own software.
Note: To run the accompanied demo program, make sure that .Net framework
3.5 is installed on your operating system. Also copy AxDIO32.dll,
AxWIO32.dll, AXWIO32.sys and DIO_for_AX92904 files to the same
folder.
Description of eachAPI function is given as follows:
1. AxInit(): Initiates AxWIO.
Function BOOL AxInit();
Arguments None.
Return TRUE: No error.
FALSE: Function fails.
2. AxClose(): Terminate AxWIO.
Function BOOL AxClose();
Arguments None.
Return TRUE: No error.
FALSE: Function fails.
3. AxInitGPIO() : Set GPIO registers to default value.
Function BOOL AxInitGPIO();
Arguments None.
Return TRUE: No error.
FALSE: Function fails.
4. AxGetConfigGPIO(): Get GPIO configuration (as digital input or
digital output)
Function BOOL AxGetConfigGPIO(byte GPIO1[], byte
GPIO2[], byte GPIO3[], byte GPIO4[]);
Arguments All GPIO configuration values read back are placed in
four 1-byte arrays:
GPIO1[]: The 1-byte array for GPIO0~7 configuration.
GPIO2[]: The 1-byte array for GPIO8~15 configuration.
GPIO3[]: The 1-byte array for GPIO16~23 configuration.
GPIO4[]: The 1-byte array for GPIO24~31 configuration.
Return TRUE: No error.
FALSE: Function fails.
