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: port speed and starboard speed). If there are more than 2 multiple data
present on the bus (for example 3 speed sensors), the repeater will only read the
information from the 2 measurement instruments with the lowest serial numbers.
A measurement instrument (with a sensor or receiving NMEA data) will only display the
data from its own sensor or from the NMEA source received, even if other similar data
are available on the bus.

2.6.2. Remote access

A repeater instrument (without a sensor) can read and write, via AS-1 bus, all the
calibration parameters or the alarm thresholds from the same type of measuring
instrument. Thus, it is possible to calibrate the speed from the MULTI display
connected to the bus.
System limitation:
For complex installations, with several similar measurement instruments, it is
impossible to calibrate alarms from a repeater instrument. In this case, these settings
can only be adjusted from the measurement unit (display to which the sensor is
connected).

2.7. Messages

There are 3 event messages which automatically disappear after 5 minutes or simply
by pressing a key:
Err Bat Displayed each time a power drop near the 9V threshold is detected (safety
threshold). Returns to normal if the battery exceeds this security level after a few
seconds.
Err MEM Displayed on powering on if a memory malfunction occurs.
