Earlier S/W version download
For some reason it might by required to "downgrade" to an earlier
S/W version. The download procedure is the same as for a new S/W.
S/W download in Display Units
New S/W for the 1728, 1735 / 1736 & 1826 / 1828 units can also be
downloaded via Win128. The PC has to be connected to the RS232
connector "J2" in the unit respectively.
See the Win128 help chapter (help topic) "Display unit menu" and the
"Technical Description" for the unit respectively.

As an alternative a restart can be done by momentarily short the two solder
pads marked "JP1" (RESET) – placed close to jumper "JP2".
