Always discharge the high voltage from components or terminals by using a safety probe. Do NOT hold the test probe when circuits over 300 volts are tested. Always use equipment certified for operation at or above the peak voltages being tested. Holt Integrated Circuits Arrow.com. Arrow.com. Arrow.com. Arrow.com.

1. Connect the mini USB lead to your PC and then to the console connector J15 on the HI-8400 board; your PC should automatically install the driver. If not the driver FT231 can be installed from the Holt Flash drive. If you have problems installing the driver, please refer to the FTDI website below: 2.
