<p><b>New page</b></p><div>RGB to HDMI converter and upscaler by Extron. Other very similar devices in the same series are the HDMI-RGB 300 (lacking analog audio input) and RGB-DVI 300 (DVI instead of HDMI and no analog audio).<br />
==Firmware==<br />
Final known firmware for all RGB 300 series devices is 1.16, with a build date of 2014-08-08.<br />
===Updating firmware===<br />
You need:<br />
#RS-232 data cable (ideally something official, I used a USB to serial DB9 dongle, then jumper wires from pin 2 to TX, pin 3 to RX and pin 5 to GND)<br />
#The firmware loader application, FirmwareLoader_v5x3.exe<br />
#The installer for the firmware blob, rgb300_series_FW1x16.exe<br />
Extron doesn't allow end users to download software from their website.<br />
==Compatibility==<br />
