USB-C-Switch Pro¶
Overview¶
The USB-C-Switch Pro is a managed USB4 1:4 / 4:1 port selector and multiplexer switch supporting pass through of 240 W USB Power Delivery Extended Power Range (EPR) - including PPS and AVS - as well as up to 2 x 8K@120 Hz DisplayPort Alt mode video.
The USB-C-Switch Pro is not a hub — it directly connects and redrives signals in either direction between the common port and one of four mux ports, appearing “like a cable” to the connected devices. Data link, power negotiation, and power delivery are handled by the attached devices themselves.
Extensive port monitoring and control features include:
Voltage and current measurement on VBUS and VCONN lines for all ports
Independent control of USB data and power connections per port
Software-controlled cable flip
The switch is managed by the HubTool application, web interface, or the multi-language BrainStem® API, via Ethernet, I2C, RS-232, or USB connections. To start using the USB-C-Switch Pro, follow the Quick Start Guide. For an overview of the capabilities of the device, see Functionality. To learn how to control the USB-C-Switch pro via API, see Software Control.
Warning
Match EPR cables: When using EPR-capable cables, always ensure that both cables in a host-device connection support 240 W. This is because EPR sources are unaware of the distal cable and will provide power based on the e-marker of the proximal cable only.
Warning
No USB-C Audio Adapter Accessory Mode (AAAM) Support: USB AAAM is a deprecated mode that allowed analog audio signal output through a USB-C port. This mode is not supported and can damage the USB-C-Switch-Pro.
