Introduction
The KanexPro SW-HDMX44DS is an HDMI 2.0 compliant 4 input and 4 output
HDMI matrixing switcher. The matrix supports a mix of both 4K and 1080p
displays to be connected and operated at the same time. The built-in 4K ->
1080p downscaler will automatically downscale a 4K HDMI video signal to 1080p
to ensure compatibility and the best possible picture on all connected displays.
It supports resolutions up to 4K@60Hz 4:4:4, HDR10, Dolby Vision. It can be
controlled via front panel buttons, IR remote and RS232 commands.
Features
• Supports resolutions up to 4K@60Hz 4:4:4, HDR10, Dolby Vision, including
1080p 3D.
• Fully compliant with HDMI V2.0 and HDCP 2.2 specications.
• Supports 4K to1080p down-scaling for each independent output to
compatibility with the legacy 1080p displays.
• Smart EDID management.
• Supports front panel buttons, IR remote and RS232 control.

RS232 Control
Connect the RS232 port to control device (e.g. PC) with RS232 cable. The matrix
switcher can be controlled by sending RS232 commands.
RS232 Commands
The command lists are used to control the switcher. The RS232 control software (e.g.
docklight) needs to be installed on the control PC to send RS232 commands.
After installing the RS232 control software, please set the parameters of COM
number, bound rate, data bit, stop bit and the parity bit correctly, and then you
are able to send command in command sending area.
Baud rate: 9600
Data bit: 8
Stop bit: 1
Parity bit: none
