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 SP-5104E,
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.
