Description
The USB-C-Switch enable selecting 1 of 4 devices to connect to a host or 1 of 4 hosts to connect to a device with up to a USB 20Gbps connection. It is software programmable with four bi-directional channels selectively connecting to one bi-direction channel. Used by companies worldwide to help automate validation and manufacturing testing of USB devices and hosts. USB-C-Switch supports: Apple CarPlay, Android Auto, USB-PD and other modes. Built inside a rugged steel housing and designed to withstand strong electrostatic discharges (ESD) of up to ±15kV.
When combined with an Acroname Universal Orientation Cable (also known as Vconn pass-thru cable), the USB-C-Switch can emulate a cable flip to connected devices with software control. The programmable flip features allows for tests of all the connections on a port without multiple manual cable plug events. A Keep-Alive-Charge circuit, controlled from software, allows the USB-C-Switch to provide charging current to devices on the 4 mux ports while they are not connected to the common port; this is useful when the devices are battery powered and may only be connected to the common port for short periods of time.
For advanced users, the USB-C-Switch includes a “split mode” which allows for mixing function groups in the connection. For example, a host on the on common port can have a data connection to a USB device on port 0, while power to the device can come from port 1. The split mode functionality enable creative solutions to problems faced by manufacturing and validation systems.
The USB-C-Switch is a device that allows engineers to control USB connections during testing and development. It has several layers of internal switches that make it a 4:1 bi-directional selector and USB-C line controller. It can act like a cable, connecting USB2, USB3, power, CC, Vconn, and SBU lines between the common port and one of the 4 “mux” ports. USB-C-Switch can be controlled using a free application or custom software via APIs in C, C++, Python, and LabVIEW. USB-C-Switch is uniquely addressable and controllable from a host PC via USB-C control port which also provides power to the system.
