Resetting the unit

There are five reset modes available by using the Reset button

( 2 ) on the front panel. The Reset button is recessed, so use of a pointed stylus, ballpoint pen, or Extron Tweeker is suggested.

CAUTION	Review the reset modes carefully. Use of the wrong
	reset mode may result in unintended loss of flash
	memory programming, the reassignment of ports,
	or a unit reboot.
	The reset modes listed below (with the exception of
CAUTION
	Mode 2) will close all open IP and Telnet
	connections and close all sockets.

If the Reset button is continuously held down, every 3 seconds the LED will pulse (blink) and put the unit in a different mode, corresponding to the underscored notes in Modes 3 through 5. The Mode 5 LED blinks three times, the third blink indicating that it’s the last mode. The following modes are listed as separate functions, not as a continuation from Mode 1 to Mode 5.

Mode 1 — Holding the Reset button while applying power will default the unit back to the base firmware that shipped with the unit from the factory. Event scripting will not start when the unit is powered on in this mode. This allows you to recover a unit that has incorrect code or updated firmware running. All user files and settings are maintained. User Web pages may not work correctly if using an earlier firmware version.

Mode 2 — Momentarily (<1 second) pressing the Reset button and typing three “+’s” into any available COM port on the IPL unit (e.g., “+++” within 2 seconds of the momentary press) will enable the connected COM port to be used as a console port to send SIS commands. If the three “+’s” are not entered in the 2 second time frame, the COM port will remain or return to being a control port only.

There will be no LED indication. If the three “+’s” are entered within the 2 second time frame, the copyright message below will be shown.

This will indicate that you have successfully enabled the COM port.

Mode 3 — Holding the Reset button until the Power LED blinks once (3 seconds) followed by a momentary (<1 second) press will turn events either on or off, depending on the current state of the events:
