AFOLUX LX Panel PCPage 88E.1 IntroductionThe DIO connector on the AFOLUX LX is interfaced to GPIO ports on the IT8712F SuperI/O chipset. The DIO has both 4-bit digital inputs and 4-bit digital outputs. The digital inputsand digital outputs are generally control signals that control the on/off circuit of externaldevices or TTL devices. Data can be read or written to the selected address to enable theDIO functions.NOTE:For further information, please refer to the datasheet for the IT8712FSuper I/O chipset.E.2 DIO Connector PinoutsThe following table describes how the DIO connector pins are connected to the Super I/OGPIO port 1.Pin Description Super I/O Pin Super I/O Pin Description1 Ground N/A N/A2 VCC N/A N/A3 Output 3 GP27 General purpose I/O port 2 bit 7.4 Output 2 GP26 General purpose I/O port 2 bit 6.5 Output 1 GP25 General purpose I/O port 2 bit 5.6 Output 0 GP24 General purpose I/O port 2 bit 4.7 Input 3 GP23 General purpose I/O port 2 bit 3.8 Input 2 GP22 General purpose I/O port 2 bit 29 Input 1 GP21 General purpose I/O port 2 bit 110 Input 0 GP20 General purpose I/O port 2 bit 0
