Vector Model Generations

To date, there have been 3 generations of the Vector G2 & G2B GPS Compasses. All are

named “Vector G2” (or “Vector G2B”), and all use the same ComNav part numbers; for

example, PN 11210001 is a Vector G2 with 15m cable & mounting brackets, irrespective of

generation.

Identifying Generations

The model generations can only be distinguished by the serial number, which is located on

the label on the underside of the enclosure.

⇒ The serial number is in the format YYWW-nnnn-nnnn (the number of digits in the

“n” fields can vary). The first four digits of the serial number indicate the year and

week of manufacture: YYWW means week WW of year 20YY.

• A first-generation model has a serial number with the first four digits being less than

0722. For Installation & Operation information on those first-generation models,

please refer to revision 1.2 of this manual.

• The second-generation model has a serial number with the first four digits being

greater than 0722, but less than 0902. For information on those second-generation

models, please refer to revision 1.6 (with Addendum #1) of this manual.

• The third-generation model has a serial number with the first four digits being 0902,

or some higher four-digit code. Revision 2.0 (or later) of this manual is applicable

primarily to the third generation (& possibly later) of the Vector G2 & G2B GPS

Compasses.

Differences between Generations

• All Vector G2 & G2B GPS Compasses are customised OEM versions of certain GPS

Compasses made by Hemisphere GPS™ (formerly CSI Wireless), of Calgary,

Alberta, Canada and Scottsdale, Arizona, U.S.A.:

– The first-generation ComNav Vector G2 is based on Hemisphere’s Vector GPS

Compass, while the ComNav Vector G2B is based on the Vector PRO. All these

models use Hemisphere’s SLX GPS receiver technology.

– The second-generation Vector G2 is based on Hemisphere’s initial MV100 series

(using their Crescent™ GPS receiver technology) – the G2 on the MV100, the

G2B on the MV110.

– The third-generation Vector G2 is based on Hemisphere’s subsequent minor

update of the MV100 series – the G2 on that MV100, the G2B on that MV110.

The third-generation G2/G2Bs also were shipped with an improved

factory-default configuration

– All ComNav Vectors have differences from the corresponding Hemisphere

models, in their operational specifications & factory-default configuration settings;

for details, please refer to the respective ComNav & Hemisphere models’

specifications.

– ComNav Vectors do not support any of Hemisphere’s various optional

GPS/DGPS receiver features or subscription applications (e-Dif, OmniSTAR,

L-Dif™, etc.).

Some of the later 2

-generation Vectors were the updated MV100/110s, but were still shipped with the original (2006)

factory-default G2/G2B configuration settings. The rest were shipped with the improved configuration – in particular, any

08xx units still in stock at ComNav at the time the new configuration was implemented, April 2009.
