SEGGER USB Hub-7

Q: Do I have to use the SEGGER USB Hub-7 with Flasher Compact?

No, but we recommend it as it is production grade, robust and tested. Many USB hubs on the market are not fully standard compliant, not as reliable and do not feature electrical isolation.

Q: Can I use the SEGGER USB Hub-7 with other SEGGER products, such as J-Link or other production programmers?

Yes. It can be used even with non-SEGGER products.

Overview

The SEGGER USB Hub-7 is a seven-port, industrial-grade USB hub that provides power to Flasher Compact units and connects them to a Flasher Hub-4 or the Flasher Hub-12.

Designed for production environments, it meets industrial standards and is tested according to EN 61326-1, EN 55011, and EN 55024/55035, covering electrical equipment for measurement, control, and laboratory use.

Key features

A white illustration of a bundle of wires stands out against a blue circular background. The wires are partially encased, suggesting a focus on connectivity or electrical components.

Upstream port isolation

The upstream port provides basic isolation (3 kV DC for 1 second), protecting your host system from potential electrical disturbances.

Overload protection

Each downstream port includes an overload limit to safeguard connected devices and ensure reliable operation in industrial settings.

High-retention USB ports

USB-B upstream and USB-A downstream ports feature high retention, keeping cables securely connected even in busy production environments.

Use case

Gang programming

Gang programming is used to increase the throughput of a programming station. The SEGGER USB Hub-7 provides a tested USB hub to simply expand the number of available USB ports to connect up to 24 Flasher Compacts with a Flasher Hub-4 or Flasher Hub-12.

Safety considerations

The SEGGER USB Hub-7 provides basic isolation only and is not intended for use with hazardous voltages without additional protective measures to prevent the risk of electric shock or fire.

The USB Hub-7’s basic isolation can withstand high voltages, as specified in the relevant technical data section. To ensure user safety when working with potentially hazardous voltages, a secondary protective measure is mandatory in case the primary insulation barrier fails. This is known as double or reinforced insulation, and the method of achieving it depends on the specific use case or application setup.

Always consult local safety regulations to ensure that all applicable requirements are met.
