Resetting the Unit

Reset to Factory Defaults Reset All IP Settings Run/Stop Events Use Factory Firmware

There are four unit reset modes (numbered 1, 3, 4, and 5), These are available by pressing the recessed Reset button on the rear panel with a pointed stylus, pen, or similar to access it. See the following table for a summary of the reset modes.

CAUTION: Review the reset modes carefully. Using the wrong reset mode may result in unintended loss of flash memory programming, port reassignment, or processor reboot.

NOTE: The reset modes listed close all open IP and Telnet connections and all sockets.

Each mode is a separate function, not a continuation from mode 1 to mode 5.
