Model JI-300 USB to I2C Adapter
The JI-300 is a versatile, easy to use PC hosted adapter used to drive I2C communications to/from a target device. The desktop unit can be configured to interface a variety of I2C networks. Bus parameters such as clock frequency, duty-cycle, setup and hold times, bus voltage, and pull-up resistor values can be varied. JI-300’s diagnostic features including “excessive clock-stretch”, “bus-not-free”, and “bus contention” monitoring, as well as status reporting at the conclusion of each message transaction simplifies I2C trouble-shooting. A Windows software application manages the setup and control of the instrument. Communications and unit power is provided via a USB 2.0 connection.
