also since the upgrade was done I cannot arm the system in either night or away mode. I did an upgrade to my GSM module and the Ultra 2 module yesterday. sine then nothing seems to be working.
Ran device explorer and rebooted. Went to DS Manager and refreshed, device was listed. Now when I refresh it says Reading SDF from device, no response.
Not sure if this will help, but below are the settings for my ETh02. Perhaps generally compare and see if you have anything different (name/IP etc excepted). Wondering if perhaps baud rate is different etc on yours.
Reading SDF from device is shown briefly when you double click the device or select settings for it
If you still have problems attach a screenshot of DS Manager settings
