How Flasher Hub-12 works

Flasher Hub-12 makes ultra-fast high speed parallel programming ("gang programming") with up to 12 channels possible. Flasher Hub-12 is connected to one or more modules (Flasher Compact). Each module is connected to a target chip. Using one of the Flasher Hub-12's host interfaces, flash programming operations can be triggered and responses from the Flasher Hub-12 can be read and evaluated. This makes the Flasher Hub-12 a perfect fit for small-scale as well as large-scale production environments.

• Power supply (see below for more information)
• One or more Flasher Compacts
• Ethernet cable (not mandatory)
• PC (Windows/ Linux/ macOS)
• The Flasher Hub-12 is set up and good-to-go in less than 10 minutes

After making sure that the devices mentioned above are all available, the Flasher Hub-12 can be setup:

1. Connect Flasher Hub-12 to power supply via the POWER connector
