NOTICE
1. While connecting a new monitor to the splitter, experiencing a short period of time no display
may be expected. Automatic EDID learning will analyze the newly connected monitor to see if
the EDID for the HDMI input is necessary to update!
2. For long range high definition HDMI transmission applications, please adopt CAT5/6 cable based
HDMI extenders.
3. Users need to install USB driver before applying firmware update process! Please search for
“PL2303” by Google and therefore use the most updated driver for your OS!
4. For firmware update through USB and since there are 2 independent microcontrollers in
AV-GM06E3-S1E, users MUST follow different steps to complete the firmware update! For some
cases, users may need to update both controllers, but in most of the cases, only one of them
may need to be upgraded. For normal uses, please do not connect USB cable to the USB port.
Please also disconnect all the HDMI source and displays to avoid any other possibilities to cause
technical issues. A 2-pin DIP switch is used for firmware update, and users can access this switch
from the bottom of the unit. The following table demonstrates the functionality that users can
change through different pin combinations.
