Error 1811 or "Gateway Address Not Set C09" message on the DM50-DM60

Products affected:
DM50™, DM55™ (K721)

When attempting to add funds, perform a data capture upload, or a system update, the meter displays the error code 1811 or message C09 Gateway Address Not Set.


This error is normally caused by the Pitney Bowes Communication device attached to the meter.  The device has either lost its network settings, or the settings have expired (for example: WiFi name (SSID) or password has changed).
