VECTOR ™- USMC VECTOR 21-V.0.3
Data transfer format for PC
A complete set of measure-
ments therefore consists of 31
ASCII characters.
Before and after this continuous
string, a steady logic 1 is
transmitted while the VECTOR
is powered on.
Start character for measurement
value:
d (v) .............................. distance
a .................................... azimuth
e ................... angle of inclination
(elevation)
Start character for error report:
C ......................... compass error
R ..........................distance error
M ............................... instrument
(main board) error
Measurement value: 6 integer
digits or six-digit hexadecimal
error code.
The data transmitted comprises:
• distance in centimetres, with
0.5 m resolution
• azimuth and inclination in
milliradians (full circle =
6'283.2 mrad) and 0.2 mrad
resolution.
Every measurement (distance,
azimuth, inclination) is transmitted
as 10 ASCII characters; 11 for
distance data:
Checksum

Checksum: 2 hexadecimal
digits. These correspond to the
8 LSBs (least significant bits) of
the ASCII measurement value
and the start character.
End character: 1 position for line
