SUB-20 is a low cost USB adapter with comprehensive and mutually convertible set of interfaces
General Description

SUB-20 is a versatile and efficient bridge device providing simple interconnect between PC (USB host) and different HW devices and systems via popular interfaces such as I2C, SPI, MDIO, RS232, RS485, SMBus, ModBus, IR and others. It is also a full "any to any" converter between all supported interfaces and I/O features. SUB-20 is a powerful I/O controller with 32 GPIO, 8 Analog Inputs, PWM Outputs, Edge DEtectors, LCD, Leds and push buttons.
SUB-20 system includes SW package containing driver, API Library, GUI and Command Line based applications, C,C++,C#,VB.net, MATLAB, LabView sample code and documentation. SUB-20 can be used with PC 64/32 bit running Windows 2000/XP/Win7/Win8/Win10, MacOS, Unix/Linux and DOS.
Working with SUB-20 does not require deep knowledge of low layers of the specific interface. All you need to do is to call right API function at the right place. And this is really very easy as API functions are well documented and "exampled". API set is relatively small but comprehensive.
SUB-20 is equipped with status Leds, optional LCD and buttons. All this guarantee fast and comfortable development, field debugging and maintenance of applications including option of standalone operation.
