For Sale is a NV-18GCP double wide Keypad, New in the Box.  This keypad can be used to replace a dark NV-E6GCP-DC keypad if you have the room in the wall to enlarge the opening for a double wide keypad.  If you do, you get an easier to read display with more functionality.  You must be running the latest firmware on your E6GM unit which is Version 2.66.  You can install it or upgrade it using the Nuvo Configurator Software which I will supply if needed.  To upgrade you will need a serial to USB adaptor so that you can connect a windows PC to the programming port on your E6GM.  They can be bought for around $15 on ebay.  I have many new and several used keypads if you should need all 6, contact me for pricing.  Will come with 4 faceplate colors.  You can buy an installation trim ring from Home Depot or Lowes and not even use an electrical box if that aids in installation.
