Hi @Simguitar , thanks for reaching out. The Moxa Lan Break Tester tool is an internal testing tool, unfortunately, it is not available to the public. You may want to consider using any fast ping tool that has resolution of 1ms to measure recovery time. Alternatively, feel free to reach out to your local Moxa representatives for assistance with testing. If you have any questions about our products, feel free to contact a Moxa representative by completing the online form: www.moxa.com/en/contact-us
