The following table describes the available settings for Channel Type:
Parameter type Setting Description
Latitude Degrees Latitude Degrees is an integer that varies from +/- 90 degrees. A positive
number represents the northern hemisphere while a negative number represents
the southern hemisphere.
Latitude Minutes Latitude Minutes varies from 0 to 60 minutes with 4 digits of decimal precision
providing a distance resolution of 0.02 meters.
Longitude Degrees Longitude Degrees is an integer that varies from +/- 180 degrees. A positive
number represents the western hemisphere while a negative number represents
the eastern hemisphere.
Longitude Minutes Longitude Minutes varies from 0 to 60 minutes with a variable number of digits
of decimal precision, providing a distance resolution of 0.02 meters.
Altitude Altitude varies from –11,000 to 21,767 meters with 0.5 meter resolution.
UTC Time UTC Time varies from 0 to 86,399 seconds.
GPS-specific
(on S1 only)
Quality of Fix The Quality of Fix, provided by the receiver, varies from 0 to 8, providing
feedback as to the dependability of the fix information. 0 indicates an invalid
fix.
Integer Any integer embedded in a string of ASCII serial data.
Float Any floating point number embedded in a string of ASCII serial data.
Device Type…
General purpose serial
device
Character Any single character embedded in a string of ASCII serial data.
mSeconds Real-time clock milli-seconds ranging from 0 to 875.
Seconds Real-time clock integer seconds ranging from 0 to 59.
Minutes Real-time clock integer minutes ranging from 0 to 59.
Hours Real-time clock integer hours ranging from 0 to 23.
Time-of day parameters
for the LogBook’s
internal real-time clock
Days Real-time clock integer days ranging from 0 to 32767.
Each serial channel represents one and only one number or character. To acquire both Longitude and Latitude, for
example, two channels must be enabled and set, respectively. When collecting data from a non-GPS device, each
desired parameter in the data [sent by the serial device] must occupy a unique channel. If the serial device supplies
three parameters and all three are to be collected, then three serial channels must be configured.
When a GPS or time-of-day (TOD) parameter is required, simply select the associated cell in the Channel Type
column of the grid, then select the desired parameter from the drop down list. When an integer, float, or character
is to be parsed from a serial input string, a format string must be formulated.
The simplest format string can be used if the serial device simply sends one parameter terminated by a
CR and/or LF. For example, a scale might send the following:
+12.32
+13.23
+13.44
+12.65
