Yes please do take a picture.  ;)
AnJu:
I connected my working Fluke 287 to the debug console.
But during boot I see only: +Entry point: 0x00060040, address range: 0x00060000-0x003beba0
When I send Ctrl C Fluke 287 shutdown and I see: $T02thread:00000001;0f:24930600;0d:64fc3b00;#f8
So I can't access to the RedBoot console.
Frenky, what the firmware version on your Fluke 287?
AnJu:
I have seen, but it does not work for mine Fluke 287
I've come to the conclusion that access to the console is closed in the latest firmware 1.16
I found the old firmware version 1.1: http://www.elso.sk/media/download/sw-drv/fluke/28xUpdatePkg_V1_10.exe
But it does not allow me to make downgrade.
To bypass protection, I need to calculate (MD5?) signature in the manifest.txt or path the firmware updater Upd28X.exe

// MANIFEST SIGNATURE
!8a28a20042f8b0a4b31d041e9ccc4c18

Any ideas?

frenky:
I do not know about firmware version, because IR is not working.
To get to console you could try sending Ctrl+C every 100ms with a script on pc or microcontroller.
That should stop loading OS and show you redboot. In my case OS load fails so I get into redboot immediately.
