Wiring and Connections
WyreStorm recommends that all wiring for the installation is run and terminated prior to making connections to the switcher. Read through this section in its entirety before running or terminating any wires to ensure proper operation and to avoid damaging the equipment.

IMPORTANT! Wiring Guidelines · The use of patch panels, wall plates, cable transmitters, kinks in cables, and
electrical or environmental interference will have an adverse effect on signal transmission which may limit performance. Steps should be taken to minimize or remove these factors completely during installation for best results. · WyreStorm recommends using pre-terminated HDMI, USB and Ethernet cables due to the complexity of these connector types. Using preterminated cables will ensure that these connections are accurate and will not interfere with the performance of the product.

· This product contains two USB-C connections that can be used as an audio/video input. When using this connection verify that the USB-C cable used supports audio/video functionality as not all USB-C cables support this requirement.

Audio Connections
A 5-pin Phoenix connector is used for balanced stereo audio output.

GPIO Ports
8-pin 3.5mm Phoenix female connector. This connector features 5V, GND, and 6 GPIO pins. Each GPIO pin can be independently configured as either a Digital Input or a Digital Output, with the default setting being Digital Input.
GPIO Voltage and Current Specifications: · 5V Pin: 5V/500mA · GPIO Pins: 5V/50mA each

Communication Connections

USB-C MST
The MX-0403-H3-MST features two USB-C ports, labeled USB-C IN 3 and USB-C IN 4, for connecting laptop devices. By default, both ports operate in SST mode (Single Screen). However, the USB-C IN 4 port can also support MST mode (Multi-Stream Transport), enabling dual-screen output. When USB-C IN 4 is in MST mode, the USB-C IN 3 port will be disabled. The USB-C IN 4 port will then transmit two video streams through a single USB-C cable, with these streams being output to both HDMI OUT ports. The resolution of the video streams will be limited to 4K at 30Hz, and the priority of the USB-C IN 4 port will be set to the highest level.
LED & Button
LED Iindicators · The MX-0403-H3-MST has video, USB, and audio indicator LEDs on the front panel. · All LEDs support two colors: green and red · The color of the LED indicators corresponds to different statuses.
Red: Selected USB input Green: Selected video/audio input White: Unselected input
Button · Two buttons are provided for video switching. · One button is available for audio switching.
