Extron electronic AVT 200HD manual Locking and Unlocking the Front Panel Executive Modes

Locking and Unlocking the Front Panel (Executive Modes)

To prevent access by unauthorized users or accidental changes to the AVT 200HD settings, you can lock most of the front panel controls by using executive modes. (The rear panel RS-232 and LAN ports and the front panel USB Config port remain accessible in all executive modes).

You can also select executive modes via the serial or LAN ports by using the SIS commands (see the executive mode commands in the “Remote Configuration and Control” section), the Windows-based control software (see the program help file) or the web pages (see “Tuner Settings Page“ in the “HTML Configuration and Control” section).

The AVT 200HD has four types of security lock that set limits for operation of the tuner from the front panel:

•Disable mode (default) — The front panel is completely unlocked (executive mode is disabled). All front panel functions are available.

To unlock the front panel, press the Menu and Next buttons simultaneously and hold them until the following message is displayed on the LCD screen (approximately

2 seconds):

EXEC MODE SELECT

DISABLE

•Complete mode — All functions are locked from the front panel except for disabling executive mode. SIS commands, the configuration and control software, the HTML pages, and the IR remote control remain available.

Any attempt to enter a command from the front panel results in the following message displayed on the LCD screen for 2 seconds:

EXECUTIVE MODE

•Volume only mode — Locks all front panel operations except volume adjustments.

Any attempt to enter a command from the front panel results in the following message displayed in the LCD screen for 2 seconds:
