Operation

Once the IPL M PDP-ES has been successfully installed and cabled, check the unit’s On/Off indicator LED ( 4 ) to ensure that the card is plugged in and communicating. At this point, the IPL M PDP-ES is ready to be configured (see chapter 3, Connection and Configuration).

If connection or communication problems occur, see Troubleshooting in chapter 4. If the troubleshooting tips do not help, check with your local network administrator, or call the Extron S3 Sales & Technical Support Hotline.

Resetting the unit

There are five reset modes available by using the Reset button

( 5 ) 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, reassignment of ports, or a
	IPL M PDP-ES reboot.
	The listed reset modes (with the exception of
CAUTION
	mode 2) closes all open IP connections to the unit.

If the reset button is continuously held down, every three seconds the LED pulses (blink) and puts the unit in a different reset 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 defaults the unit back to the base firmware that shipped with the unit from the factory. Event scripting does 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 with an earlier firmware version.

Mode 2 — Momentarily (<1 second) pressing the reset button and entering three “+”s into the RS-232 port of the interface card (e.g., “+++” within 2 seconds of the momentary press) enables 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 remains or returns to being a control port only.

A mode 2 reset disconnects a pass-through connection.

Mode 3 — Holding the reset button until the Power LED blinks once (3 seconds), followed by a momentary

(<1 second) press turns events either On or Off, depending on the current state of the events:

•If the events are currently stopped following the momentary (<1 second) press, the Power LED flashes twice, indicating the starting of events.
