We have analysed the Bus monitor log that you send. It is a very large log recorded over 2 days, which has been very helpful.

We can see the problem occuring on some 4 or 5  occasions over the 2 days after the keypads have been reset on the hour. Only 1 keypad is affected  at a time due to a wrong reply to  the vocab info from Comfort. The strange thing is that the correct reply is given to 2 keypads but the wrong reply is given to one of the keypads. It appears that Comfort finds an invalid value in the vocab info temporarily, (for a fraction of a second)


This problem is exarcebated by resetting the keypads every hour because that is when the keypads request the vocab  info

The possibilities are;
  1. There is a firmware bug in Comfort which is appearing in your system due to certain unknown conditions
  2. There is some fault in the DSP module of Comfort
  3. Environmental conditions are causing the problem eg extreme cold , power supply etc
We will do the same resetting of the keypads every hour and see if we can duplicxate it. If we can confirm if it is due to a hardware problem we will send a replacement DSP board to replace the one you have


Perhaps you can try to make it warmer for the Comfort so see if this is a cause?
