This page covers both halves of the kit; pick the unit and the cart follows that Extron part number.
The UCS T 503 transmitter takes in USB-C and dual HDMI with USB inputs for BYOM laptops, while the UCS SR 501 scaling receiver adds an HDMI with USB input for a dedicated UC room computer and an HDMI output to the room display. Together they switch up to six USB room devices: one port runs up to USB 10 Gbps at 5 V, 900 mA, and five more run up to USB High Speed (USB 2) at 5 V, 500 mA each.
