Model JI-216 I2C Bus Monitor - USB
The JI-216 I2C Bus Monitor is a low cost, easy-to-use PC hosted instrument specifically designed for troubleshooting and debugging I2C networks. The JI-216’s high speed FPGA based architecture captures and displays all valid, or invalid I2C messages up to and including the 3.4Mbits/s HS bus rate. Variable SDA/SCL filtering, a signal voltage range range from 0.5V to 15.0V, and selectable triggering provides flexibility in monitoring a variety of I2C systems. An intuitive Windows application manages instrument setup and control. Communications and unit power is provided via a USB 2.0 connection.
