    0914). Vector Generations The generation of a Vector G2 & G2B can be determined by the initial 4 digits of its serial number, which are a “date code” identifying the year and week it was manufactured. The serial number is on the label on the underside of the enclosure.
  • Page 3 Secure the cable along the route using plastic tie wraps as necessary Cables & Extensions There are two standard cable lengths supplied with the Vector G2: 15 metres & 30 metres. If the standard-length cable supplied with your kit is too long, you may shorten it as required.

  • Page 4: Standard Cables

    Wiring Standard Cables There have been five different standard cables supplied with ComNav Vector G2 & G2B GPS Compasses, across the two generations – three 15 metre cables, and two 30 metre cables. The main difference between the various cables is in the colour-coding of the wires. The wire colour codes depend on the cable’s “marking”...
  • Page 5 Vector, the signals available on the cable depend on both the cable type and the Vector’s generation. If the older cable types are used with a second-generation Vector G2 & G2B, the Alarm output is not provided!

  • Page 7 On the other hand, it is sometimes better – from the perspective of signal integrity and/or electrical noise-reduction – to connect some or all of the Grounds in a system. Consult your ComNav Dealer for help, if you are unsure what will work best on your vessel. Serial Port Settings Both ports use ordinary asynchronous serial data formatting, as specified in the NMEA 0183 Standard;...

  • Page 8: Interfacing To A Comnav Autopilot

    Figure shows the typical connections used with a ComNav Commander P2 Autopilot System (an Admiral P3 would be wired identically), a ComNav Navigator G2 GPS Compass Display System, and a generic Chartplotter or other type of Navigation System. Note: this wiring information assumes that the G2 is in its factory-default configuration: Autopilot data on Port B, and General Navigation data on Port A (see pages 14 &...

  • Page 10 PC serial ports – commonly referred to as “COM ports” – always use RS-232 signal levels, and so the only possible direct connection to the Vector G2 is via the G2’s RS-232 signals. If it is necessary to connect a PC to any RS-422 signals (for example, when the PC is being used to run a Navigation program, which sends steering commands to an NMEA 0183 autopilot –...

  • Page 14 One program for controlling the G2 and displaying its output Selection of which COM port on the PC to assign for “Navigation” use, and which port for “Vector G2” use, as well as Baud rates, will depend on the programs used. Document PN 29010078 V1.6 (Addendum #1)

  • Page 15: Normal Operation

    – All ComNav autopilots need heading to be updated at a rate of about 10 Hz or more; any slower causes the autopilot’s steering control algorithm to respond too slowly to changes in the vessel’s actual heading (from wind, waves, current,...
  • Page 16 Configuration Output Data Formats There are three formats that the Vector G2 can output data in: the NMEA 0183 Standard’s format, a proprietary format, and a binary format. For full details on the NMEA sentences, please refer to the NMEA 0183 Standard. For details on the G2’s specific capabilities (fields, format, etc.) in the NMEA 0183 sentences,...
  • Page 17 … “NMEA-like” because these sentences follow the general syntax rules of NMEA 0183, although they are not part of that standard, but rather have been defined by Hemisphere GPS. These sentences are available only on their own GPS products, and equipment based on those – such as the Vector G2. Document PN 29010078 V1.6 (Addendum #1)
  • Page 18 (especially at RS-232 levels). Each of the Vector G2’s two output ports can be configured, independent of each other, to communicate at all conventional Baud rates from 4800 up to 38400 Baud.

  • Page 19: Changing The Configuration

    ComNav Vector G2/G2B Installation & Operation Configuration Changing the Configuration You may change the factory-default configuration of the Vector G2, if you wish! • Many other output sentences can be enabled, and/or the factory-default ones disabled, to suit the requirements of any specific installation.

    PC’s first COM port; if you want to monitor both of the G2’s ports, Port B should be connected to the PC’s second COM port. HDM & the other “unknown” sentences/parameters were part of the customizations added in ComNav’s variant of the Hemisphere Crescent product, but they were added after PocketMAX was designed.
  • Page 21 … unless you are sending the command on Port B’s Rx wire, in which case the “OTHER” parameter means “Port A”. To avoid confusion, ComNav recommends that all command input to the G2 be done on Port A. Document PN 29010078 V1.6 (Addendum #1)

  • Page 23 ComNav Vector G2/G2B Installation & Operation Configuration Command Description $GPMSK,parameters Tune the Beacon receiver • Enable GPGGA, GPGSA, GPVTG & GPZDA at 1 Hz • Set both ports Baud rate to BAUD (4800, 9600, 19200, $J4STRING,BAUD[,OTHER] 38400) • Do a $JSAVE (see Table 11)
  • Page 24 Table 11 – Status Query & Save Configuration Commands The $JRESET command should NEVER be used!! It does not reset the G2’s configuration to the ComNav factory defaults, as you might expect, but instead to Hemisphere GPS’s own factory defaults, which are quite different (including the Baud rates being 19200).
  • Page 25 Note: the GPS Technical Reference manual describes many features and functions of the Hemisphere GPS Crescent technology that are not available in ComNav’s G2/G2B products. Some specific areas you should ignore are: • All “subscription”, e-Dif, L-Dif & OmniSTAR features, and related commands.
  • Page 26 Configuration Customising & Fine-tuning the Configuration There are a number of situations where you might want to change the Vector G2’s factory-default configuration settings in ways other than simply enabling or disabling the specific sentences that your system requires, or changing the update rates of the enabled sentence(s).
  • Page 27 Configuration Disabling the Tilt Sensor The Vector G2’s tilt sensor is enabled by default. You can turn the tilt sensor off with a $JATT,TILTAID,0 command. The only time you might need to do that is when troubleshooting, to ensure the GPS receiver is working properly.
