USB System Architecture

A USB system architecture refers to the physical bus topology of USB devices connected
to a host device. USB devices include USB hubs, USB peripheral devices, or compound
devices (devices with a combination of USB hubs and USB peripheral devices built into it).
The system is organized in a tiered star topology to prevent multiple or circular attachments
to the bus. Each tier represents a degree of separation from the host device. Per USB
specifications, there are seven supported tiers, starting with the host device (or root hub)
occupying the first tier.
NOTE: Do not connect more than five daisy-chained hubs to the root hub. The
Four port output hub with USB‑C and Type A connections — Enables
simultaneous connection to multiple peripheral devices with USB-C or Type A
connections such as mass storage devices, keyboards, mice, or other Human Interface
Devices (HIDs).
Supports selectable Host and Peripheral emulation — Emulates uninterrupted
connection between host, keyboard, and mouse devices. This feature enables devices
to remain functional when switching between inputs.
Front panel selection buttons and status indicators — Facilitates easy control and
troubleshooting from front panel.
Built‑in web pages — Enables the use of a standard browser for device monitoring
and troubleshooting over an intuitive web interface.
Ethernet and RS‑232 control options — Provides multiple control options for pro AV
environments.
Front panel security lockout — Prevents unauthorized use in non-secure
environments. In lockout mode, a special button combination is required to operate the
switcher from the front panel.
Rack‑mountable, 1U half rack width metal enclosure
External Extron Everlast power supply included — Provides worldwide power
compatibility with high-demonstrated reliability and low power consumption.
Extron Everlast Power Supply is covered by a 7‑year parts and labor warranty
architecture does not support peripheral devices connected to USB hubs occupying
the seventh tier.
