Hardware Reset Modes:
CAUTION:
The reset modes listed below will close all open IP and Telnet
connections, and close all sockets
With power on, when the reset button is held down, every three seconds the rear panel
LED will pulse (blink). At the first blink Mode 3 is available, at the second blink Mode 4 is
available and the third blink indicates Mode 5 is available. The reset modes have separate
and distinct functions outlined below. Additional information is available in
Hardware Reset Modes.
MODE 1 — Firmware reset: Disconnect power to the DMP 64. Press and hold the reset
button while applying power to return the firmware to the version shipped with the unit
from the factory. Event scripting will not start when powered on in this mode. This allows
recovering a unit with incorrect or corrupt firmware.
All user files and settings are maintained. Some user web pages may not work correctly if
returning the unit to an earlier firmware release.
MODE 3 — Events reset: With power on, press and hold the reset button until the reset
LED blinks once (~3 seconds). Release the reset button, then within one (1) second press
it again to toggle events On or Off, depending on the current state.
If the event logging is currently stopped, following the momentary (<1 sec.) press, the
reset LED will flash twice indicating events logging has begun.
If the events are currently running, i.e., digital I/O scripts, following the momentary
(<1 sec.) press, the reset LED will flash three times indicating the events logging has
stopped.
Each flash will last for 0.25 seconds. If the second momentary press does not occur within
1 second Mode 3 is exited.
