The JI-300 is a versatile, easy to use, PC hosted adapter used to drive I2C communications
to/from a target bus. 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.visit:www.jupiteri.com.
