Extron electronic SW DVI A Series Updating Firmware, Setting equalization for input sources

Operation, cont’d

Setting equalization for input sources

High and low EQ levels for each input can be selected via the Input EQ DIP switches on the front panel. Setting these switches to High (up) compensates for a degraded/poor quality signal, reducing the need for additional signal conditioning equipment.

If the input signal is strong, set the switches to Low (down).

Resetting

To reset the switcher to its factory default settings,

1. Press and hold the Input 1 button while power is being applied to the unit.

2. Continue holding the Input 1 button until the power-up sequence completes.

NResetting restores the EDID to a resolution of 1024x768 @ 60 Hz.

Updating Firmware

Updates to the SW DVI A Series firmware are made available periodically via the Extron Web site. The Firmware Loader software, also available from the Extron site, enables you to replace the firmware that is coded on the SW2/SW4’s control board.

You can find out what version of firmware is currently loaded on your switcher by entering the SIS “Q” command via the RS-232 interface. See chapter 4, “SIS Configuration and Control,” for the procedure for entering SIS commands.
