Why Buy an XP400 Device?
- If your Original XP400 for IM608 / IM600 is broken, you can buy this to replace the old one. Or if you have a MaxiIM IM508 or Otosys IM100 and want to perform advanced IMMO reprogramming like the IM608 / IM600, you can add an XP400 to your setup. It then enables IMMO functions equivalent to those of the IM608 / IM600.
