Hardware Reset Modes:
NOTE: The reset modes listed below will close all open IP and Telnet connections,
and close all sockets.
The reset modes have separate and distinct functions. Additional information is available
(see
DMP 64 Hardware Reset Modes on page 138).
Each reset LED flash lasts for 0.25 seconds.
MODE 1 — Firmware reset:
1. Disconnect power to the DMP 64.
2. Press and hold the reset button.
3. Apply power to the device while holding the reset button.
Mode 1 will:
• Return the firmware to the version shipped with the unit from the factory. This
allows recovering a unit with incorrect or corrupt firmware.
• Maintain all user files and settings.
NOTE: Some user web pages may not work correctly if returning the unit to an
earlier firmware release.
MODE 3 — Events reset:
1. Apply power to the DMP 64.
2. Press and hold the reset button until the reset LED blinks once (~3 seconds).
Release the reset button,
3. Within one (1) second press the reset button again to toggle events on or off,
depending on the current state.
•
If event logging is currently stopped, following the momentary (<1 sec.) press,
the reset LED will flash twice indicating events logging has started.
• If any events are currently running, following the momentary press, the reset
LED will flash three times indicating that events logging has stopped.
If a momentary press does not occur within 1 second, the events logging status
before entering reset will remain.
