1.2 Safety of transmission
Data transmission from transmitter to receiver is supported by various levels of safety in order to ensure
continuous and reliable reception:
1.Each transmitter works with an allocated address. This address is commu-
nicated to the dive computer on pairing. There are more than 60,000 addres-
ses. This assures that no two transmitters send on the same channel. The pai-
ring of transmitter and receiver is also carried out by a process with various
safety levels in order to prevent faulty pairing.
2.Data are transmitted with an average interval of 5 seconds. The exact point
in time of the transmission is variable. This prevents two transmitters from
disturbing each other for longer periods.
3.Together with the pressure data additional informations are transmitted. This
allows reconstruction of faulty data and, on the other hand, where this is
no longer possible, recognition of useless data.
By means of these safety measures, faulty transmission is almost impossible.
In spite of that, the transmitted measurements are subjected to an additional
plausibility check. Only such data are used which are sensible in the current
situation.
