In our setup, I have 8 HD210W's and several XD230's - twice now, I've accidentally sent a presentation designed for a XD230 to our network of 220's - resulting in the dreaded "not for this unit - remove SD card and reboot" message on the displays. As far as I can tell, the only way to resolve this is to set them up again using a fresh SD Card configuration.
Is there no way to prevent this from happening, and is there a quicker way to get the units back to life, preferably without having to walk to each of them, especially since two of them are in remote locations. Sure, it is a silly mistake to make, but the results seem like something that software could catch and prevent?
