Survey Data Message Format
Range data downloaded in Criterion 400 Mode has the following general
format:
$PLTIT,HV,hd,hu, , , inc,iu,sd,su*cs<CR><LF>
$PLTIT The Criterion message identifier.
HV The Criterion Horizontal Vector message type.
Hd The horizontal distance. In an UltraLyte LR B this
field contains the slope distance.
Hu The units in which hd 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 LR B.
Inc Inclination measurement. In an UltraLyte LR B this
field always contains 0.00.
Iu Inclination units. Legal values are D (degrees) or
G (gradients). In an UltraLyte LR B this field contains
the factory default angle units even though the inc
value is always zero.
Sd Slope distance.
Su Slope distance units. Legal values are F (feet) or
M (meters).
*cs An asterisk followed by a hexadecimal checksum.
The checksum is calculated by XORing all the
characters between the dollar sign and the asterisk.
<CR><LF> A carriage return/line feed combination, which
terminates each Criterion-format message.
If a measurement error occurs, the message downloads null values for
the measurements that failed.
