5.3.2
Field programmability of the instance fields
NCP support field programmability of all the system and device instances fields within
NAME entity.
This can be done with PGN 126208 Command Group Function.
5.3.3
Load Equivalency Number
Low power
–
126mA at 12 VDC (3 LEN) from NMEA 2000 bus.

NMEA 0183
The NMEA Connect Plus has two RS485 interfaces to be used as NMEA 0183 ports,
whereby two wires are used to transmit the NMEA data.
Both baud rate 4800 and 38400 bauds can be used. The default value is 4800 bauds
but it can be changed via Webserver. The default baudrate of Calypso ULTRASONICs
is:
Wired
Standar
Wired BLE/
Wired WIFI
ULP 485
Baudrate
4800
4800
38400
The NMEA0183 ports can be configured either as input or output (Only one port can
be configured as input). By default, Port 1 is configured as input and Port 2 as output.
The NMEA0183 port, receives wind data from the ULTRASONIC wired and exports it to
an NMEA 2000 network, NMEA 0183 network and Bluetooth interface. Moreover, it
can also send wind data via Wi-Fi using the Wi-Fi NMEA 0183 server.
The NMEA 0183 sentences supported by the NCP are shown in the following section,
note that the NMEA 0183 output always send the wind speed in knots.
When the NCP is used on a NMEA 0183 network, the cable with end free wires should
be connected through the unit (follow the instructions in section 6.3).
Keep in mind that if the unit is connected to an NMEA 2000 network, you do not need
an extra power connection. Otherwise, you must power the device using the dedicated
VCC input or the USB power.
5.4.1
NMEA 0183 sentences
NCP is able to receive the following wind sentences (firmware version V1.11 and
higher):
$IIMWV,XX,R,XX.XX,N,A*CR\r\n
Wind speed in knots
$IIMWV,XX,R,XX.XX,M,A*CR\r\n Wind speed in meters/sec
$IIMWV,XX,R,XX.XX,K,A*CR\r\n
Wind speed in Km/Hr
