BZBGEAR BG-USX-B100BC PRODUCT MANUAL
Introduction
The 2-Port USB 3.2 Gen 1 Extender Kit is designed to deliver reliable, high-speed
USB connectivity over long distances using a single CAT6a cable. Supporting USB
3.2 Gen 1 with data transfer rates up to 5Gbps, the system extends USB signals up
to 100 meters (328 feet) while remaining fully backward compatible with USB 2.0
and USB 1.1 devices. The transmitter provides dual selectable host inputs (USB-C
and USB-B), allowing flexible connection to different host systems, while the
receiver offers multiple USB device ports, including both USB-C and USB-A, to
support a wide range of peripherals.
Engineered for professional and industrial applications, the extender features
bi-directional 24V Power over Cable (PoC), enabling either the transmitter or receiver
to power the entire system and simplifying installation. Advanced hardware
acceleration ensures stable isochronous and bulk data transfers, making the
solution well-suited for bandwidth-sensitive devices such as PTZ cameras,
webcams, touch panels, and industrial cameras. Additional capabilities including
RS-232 pass-through, FSYNC GPIO signal transmission, API control, and firmware
upgrade support provide seamless integration into control systems and demanding
AV, broadcast, and automation environments.
Features
● Long-Distance USB Extension: Extends USB 3.2 Gen 1 signals up to 100m (328ft)
over a single CAT6a (F/FTP) cable.
● High-Speed Data Throughput: Supports USB 3.2 Gen 1 with data transfer rates up
to 5Gbps for bandwidth-intensive devices.
● Backward Compatibility: Fully compatible with USB 2.0 and USB 1.1 devices.
● Dual Host Inputs: Transmitter includes one USB-C and one USB-B selectable host
input for flexible system integration.
● Multi-Port Device Connectivity: Receiver provides one USB-C and three USB-A
device ports to support multiple peripherals simultaneously.
● Bi-Directional Power over Cable (PoC): 24V PoC allows either the transmitter or
receiver to power both units, reducing power supply requirements.
● Automatic and Manual Host Switching: Supports auto-switching via USB 5V
detection as well as manual host selection.
● Isochronous and Bulk Transfer Acceleration: Hardware acceleration ensures
stable performance for real-time and high-bandwidth USB devices.
● RS-232 Pass-Through and API Control: Enables remote control, monitoring, and
integration with third-party control systems.
● FSYNC GPIO Pass-Through: Supports FSYNC signal transmission for synchronized
industrial and machine-vision camera applications.
● Firmware Upgrade Support: Dedicated USB-C service port allows easy firmware
updates and maintenance.
