Data Transfer Format For Pc - Vectronix USMC VECTOR 21 Operating & Operator Maintenance Instructions

Data transfer format for PC

Every measurement (distance,
azimuth, inclination) is transmitted
as 10 ASCII characters; 11 for
distance data:
Z XXXXXX XY <CR>
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.
