I'm trying to update my DSP7200SE and DSP5200SEHC speakers. I am using the following:

Windows 10 Laptop -> USB cable -> Keyspan USA-19H -> RS232 cable -> Reviver -> RJ45 cable -> SpeakerLink In port

I initially could not see the Kayspan adapter as a COM port, which I resolved by installing the Windows 10 driver. I now see the adapter as COM5, which appears in the Meridian Flash Upload Program.

When I run the MFUP, select the firmware file and click on start I get the message "A manual reset is required. Please turn the power to the product off and on". No matter how many times I turn the power switch on the speaker off and on the message remains. Can anyone advise how I can solve this issue?
