POWER AND DATA
COLOR DESCRIPTION
Red DC positive (+) (12-24 volts). Always use a 2A
fuse or circuit breaker. Do not connect directly
to battery. If you must extend the power
connections use high quality pre-tinned marine
grade wire which is at least 16 AWG (1.5mm
2
).

NMEA 0183 EXAMPLE
• A dedicated VHF antenna or Vesper Marine AIS/VHF Antenna Splitter
is required.
• Make sure your VHF antenna is an omni-directional antenna designed for the
marine band (156-162MHz) and is well tuned at the AIS end of the band (VSWR
2:1 or less at 162MHz).
• Mount the antenna as high as possible (at least 2-3 metres (6-10 ft) above
the water surface) and as far as practical from any existing VHF, HF or radar
antennas and any metal structures. It is not recommended to place the VHF
antenna directly alongside a mast or another VHF antenna such as on
a mast-head.
CAUTION: Never operate this device unless it is connected to a suitable VHF
antenna or Vesper Marine AIS/VHF Antenna Splitter. Performance cannot be
assured if you use any other antenna splitter. The use of an improper splitter
may damage the device and void your warranty.
HINT: Use the VSWR meter in the vmAIS or WatchMate App
(see configuration section) to check your antenna system installation.
• The XB requires a GPS fix before it can transmit its position.
• The GPS antenna should be situated so that it has an unobstructed
view of the sky above.
• Do not place the GPS antenna near or in the path of radar or
HF antennas.
• The antenna cable is terminated with a small SMA connector to
facilitate easy routing through holes and openings. Do not cut the
cable unless you have the proper tools to crimp a new connector.
Make the connection to your AIS transponder last after antenna
installation is complete.
CAUTION: The GPS antenna provided is designed specifically for
use with the XB Transponder. Performance cannot be assured
unless you use a Vesper Marine GPS antenna. Use of a different
antenna may damage your XB and void your warranty.
HINT: Use the GPS Status screen in the vmAIS or WatchMate App
(see configuration section) to view satellite signal strengths which
will assist in determining the best location for the antenna.
!
A 2m (6.5’) cable with attached 10 pin connector is supplied for connecting the
XB to power, other devices over NMEA 0183 and an external silent mode switch.
You may extend this cable as necessary.
• Check you have the VHF antenna connected before connecting to power.
• Fully engage the locking ring to ensure a watertight seal.
• Received NMEA 0183 data is output on WIFI* and USB.
Hint: Silent Mode
can also be controlled
over USB and WiFi*.
External switch is
an optional manual
override.
