Survey Data Message Format

In Criterion format, the UltraLyte downloads
survey data messages in this format:

$PLTIT,HV,

, ,

inc

<CR><LF>

where:

$PLTIT

is the Criterion message identifier.

indicates the Criterion Horizontal Vector
message type.

Note:

Historically, the HV

data line has been the most commonly
used of all Criterion data line types, and
hence is the only type supplied in the
UltraLyte.

is the horizontal distance. In a UL100,
this field contains the slope distance.

is the units in which

is expressed.

Legal values are F (feet) or M (meters).

Followed by three commas, indicating
two null fields for Criterion values not
measured by the UltraLyte.

inc

is the inclination measurement. In a
UL100, this field always contains 0.00.

is the inclination units. Legal values are
D (degrees) or G (gradients). In a

UL100, this field contains the factory
default angle units even though the

inc

value is always zero.

is the slope distance.

is slope distance units. Legal values are
F (feet) or M (meters).

*cs

is an asterisk followed by a hexadecimal
checksum. The checksum is calculated
by XORing all the characters between
the dollar sign and the asterisk.
