2.5. Standby
To save energy on board, the "WIND" display can be placed on standby by pressing
for 2 seconds on the
key.
Standby mode switches off backlighting, the screen, stops sensor measurement and
processing of NMEA input and output interfaces. Only the vital bus management and
keyboard functions remain active. Active displays present on the bus indicate
measurement impossible with an OFF icon instead of the data.
Standby mode is not saved.
At any time, simply pressing one of the four keys
or cutting off the power stops standby mode and returns all device
functions to normal.
2.6. Network operation (Bus AS-1)
The AS-1 bus is used to connect products in the advanSea family via a rapid and
reliable exchange protocol. Only the bus wires need to be connected. No startup
settings are required.
The communication protocol allows for multiple data exchange at previously defined
transmission speeds.
Thus, it is possible:
to exchange several similar measurements on the same bus, for
example: several anemometer sources.
to change the units, the alarm threshold values or to calibrate from a
single instrument.
to activate or deactivate alarms from a single instrument.
The protocol allows exchange of similar data from different sources (direct
measurement from the sensor, or from the bus or via NMEA).
2.6.1. Displaying multiple data
In order to display multiple data, a repeater instrument (without a sensor) should be
differentiated from a measurement instrument (with a sensor or receiving NMEA
data).
A repeater instrument can display maximum 2 multiple data available on the bus
(for example: wind vane-gauge sensor no.1 and wind vane-gauge sensor no.2). If
there are more than 2 multiple data present on the bus (for example 3 wind vane-
gauge sensors), the repeater will only read the information from the 2 measurement
instruments with the lowest serial numbers.
