Electrical specifications
Buzzer output
(green wire):
Switched to ground, open collector, 30 V DC and 300 mA max.
It is recommended to protect this output with a 300 mA fuse.
NMEA 0183:
Version 3.01, asynchronous 4800 baud, 8 bit link, without
parity, 1 stop bit. The electrical levels used on the NMEA output
are referenced to the ground and vary according to the system’s
voltage supply.
On powering on, a proprietary NMEA frame
$PNKEV,DEPTH
V1.00*4E
is sent to identify the transmitter.
Communication
bus:
Half-Duplex 38400 baud link on one wire. Words are sent on 8
bits, without parity with 1 stop bit. The number of devices
connected to the bus is limited to 20.
Power supply:
9 volts to 16.5 volts / Consumption <150m
