Extron Media Presentation Matrix Switcher MPX Plus 866A No Signal

Post by Shmups Hero »

Where can I find the latest firmware and programs for Extron MPX Plus 866A? All of them are locked behind an insider account and that is required on the Extron website to download the

latest firmware, program and the latest DSP configurator software. I believe this Extron MPX Plus 866A needs a newer firmware or it just give me no signal with VGA :cry: .

Another post on this forum about Extron Crosspoint Switcher firmware did have the same problem and solved it by upgrading. I have tried with two of the older MPX Plus 866A firmwares already with no success. I can't get access easily to an insider account and I spotted that post on Shmups a few months back and they got a download link to the latest firmware which is why I'm asking on here now. I have an account and I'm making my first post on this forum too :roll: . If you would please be so kind to link me all of the latest Extron programs & firmware for this unit I would be really grateful. Testing composite when I can or have upgraded firmware from you

The programs and firmware I need listed:

DSP Configurator software
(top right on the Extron webpage for this unit)

MPX Plus 866A firmware
(Main site header [DOWNLOAD] {Find Software & Downloads} {Firmware} -> Download center)

Extron Matrix Switchers software
(Extron webpage for this unit under the section [Downloads] for this unit)

Thank you beforehand for your help :D
