I2C Bus Monitor

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.

Compatible with Standard-mode (100kbit/s), Fast-mode (400kbit/s), Fast-mode
Plus (1.00Mbits/s), and High-Speed mode (3.4Mbit/s)

Time stamping and message period timer

I2C messages displayed in either Real-time Streaming* or Trigger mode

USB 2.0 host interface – No external power required

* Real-time streaming mode limited to an aggregate maximum, sustained throughput rate of
1.0Mbits/s
