Some quick comments....
The E30 never had MSX capability as it was discontinued with the release of the MSX equipped Mk2 models
The Mk1 Exx series are not capable of producing the full MSX functionality due to hardware limitations
The Mk2 Exx series are capable of MSX functionality and are identifiable by their later facelifted keypad layout.
MSX is a functionality that captures edge detail in teh secene using a visible light camera and overlays the edges onto the thermal image to provide scene context. Image Fusion is a standard visible light image overlaid on the thermal image with varying levels of transparaency. No edge detection or enhancement is present so the users brain needs to interpret the combined images. MSX can sometimes be easier to interpret due to the absence of a coloured visible light image conflicting wit the colours in the thermal image.
Mk1 Exx series cameras run different firmware to the later Mk2 version. The Mk1 firmware contains the very useful service menu and is easily upgraded to full resolution and additional menu's. The Mk2 may also be upgraded to full resolution and additional menus but there is nor service menu present. The increased temperature capability may only be achieved via the service menu.
The model you detailed is a 'B' suffix model intended for building survey work so has limits placed on its temperature coverage. It also may, or may not, contain the Wireless module. In some E30 models, greater temperature capability is releasable using the service menu.
