 The bus address  (96) can be found in the meters keypad screen #3, Paramter name 'Pri_Adr1'.

+|Energy     | CE0                         | 0.001 Gcal |

+  The driver returns integer values. You should scale them appropriately to get exact values using Multiplier field
+  in register properties.
+== Driver test procedure ==
+Before testing the protocol in the field, it's preferrable to test it in a lab (if you have a meter on-hand).
+To simulate temperatures you can use resistors or potentiometers, note that return temperature have to be less than forward for 3 or more degrees (otherwise energy won't work). Flowmeter can be simulated by shorting 10-11 pins of i/o board.
