Ok, I should better have looked in our documentation before sending the 
last mail. Sorry for that.

The first bytes in your log are the "small header" as documented: 
:cf:46:00 (Profile length in bytes)
:02 (Sampling rate)
:07 (Amount of  divisors)
:00:02:06
:01:02:06
:02:01:0c
:03:09:02
:04:0f:0c
:05:02:0c
:06:00:00 (7 divisors with ppO2 data)

First real samples:
:91:01:00 -> 401mbar depth
:dc:01:09:00:00:00:00:00:00:00:00:00 -> 476mbar depth + (empty) Sensor data
:12:02:00 -> 530mbar depth
:44:02:09:00:00:00:00:00:00:00:00:00 -> 580mbar depth + (empty) Sensor data
:63:02:00 -> 611mbar depth

and so on. All fine sample data. It basically stops transmitting in 
packet #395 for no known reason.

Matthias
