Assign device icons — Displays the complete set of input and output device icons. You can drag any of these icons to the input and output boxes.

Edit device palette — Allows you to add your own device icon graphics.

RGB delay settings — Displays the switching interval setting for each input and allows you to change them.

Audio-Input gain settings — Displays the audio gain level setting for a single input or for all inputs and allows you to change it. The level is expressed as the magnitude (number of decibels) and polarity (positive, gain or negative, attenuation) of the audio adjustment.

Audio-Output volume settings — Displays the audio

output level setting for a single input or for all inputs and allows you to change it. The level is expressed as a percentage of the input audio volume that is applied to the output; 0% is full attenuation (audio is silent), 100% is full volume.

Mute-Output settings — Displays the RGB Delay, Volume, and Mute Adjust screen, which allows you to mute and unmute individual or all video and audio outputs.

View input frequencies — (DSVP) Displays the input horizontal and vertical frequencies for each input.

Update ﬁrmware — Allows you to replace the ﬁrmware that is coded on the switcher’s control board without taking the switcher out of service, opening the switcher enclosure, and replacing the ﬁrmware chip set. See Update ﬁrmware on page 5-14.

IP options — Allows you to set IP options. See IP Settings/Options window on page 5-7.

HTML ﬁle manager — Displays a list of HTML ﬁles installed on the switcher and allows you to upload custom ﬁles from a connected PC to the switcher. See Upload HTML ﬁles on page 5-15.

Hardware status — Provides an overall view of the status of the matrix switcher, including the primary and secondary power supply status and the individual voltages, the fan and temperature status, the Remote RS-232/RS-422 port conﬁguration, and the installed and updated ﬁrmware status (ﬁgure 5-9).
