1.2 Reliability of transmission
Data transmission from transmitter to receiver is supported by various levels of redundancy in order to war-
rant undisturbed and reliable reception:
1.Each transmitter works with an allocated address. This address is communi-
cated to the dive computer on pairing. There are more than 60,000 addres-
ses. This assures that no two transmitters will transmit on the same channel.
The pairing 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 in 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 information is transmitted. This
additional information allows the Aladin
®
Air Z to reconstruct faulty data and
recognize useless data.
By means of these redundant measures, faulty transmission is almost impos-
sible. In spite of that, the transmitted measurements are subjected to an addi-
tional plausibility check. Only such data are used which are sensible in the
current situation.
