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 depth and starboard depth). If there are more than 2 multiple data
present on the bus (for example 3 depth 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 depth from the DEPTH 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.
Err Bus
Displayed at the first detection, after powering on, if a bus wire is pinched
(incorrect wiring).
