THE
‘CC’
COMMAND
The ‘CC’ command is used to select a GPS data field and copy it to a Graphic Field for display on the
overlay. The data supplied by the GPS is often not formatted appropriately for display. The CC command
provides formatting options for specific types of data to convert them into other formats. For example latitude
may be provided as “4255.1977” by the GPS. The CC command has an option to convert it to “42° 55.1977’”
for display.
The format of the CC command is:
CCnnFmmMff[Aaaa][Bbbb]
The lower case items represent numbers and the items in brackets are optional or dependent on the
formatting method selected. In all cases, nn represents the Graphic Field number that text will be stored in,
mm is the GPS data field number to read, and ff is the formatting mode.
The following CC command example sets the text content for Graphic Field 01 and specifies that it should
be set using GPS data field 3 (Latitude). Format method 1 is used in this example, which is a simple copy of
the GPS data directly to the Graphic Field.
CC01F3M1
The available formatting options are described in Table 19.

Description
1
Copy the GPS Data to the Graphic Field without any formatting changes. No optional
parameters are available for this format method.
This format mode can be used for any data field.
The command syntax is CCnnFmmM1 where, nn is the Graphic Field to set and mm is the GPS
data field to copy
2
Copy with leading zero suppression. If the data field contains leading zeros, they are removed
when the data is copied to the Graphic Field.
The command accepts optional parameter A1 that causes the leading zeros to be replaced with
spaces instead of being removed.
This format mode is intended for use with GPS data fields containing a number
The command syntax is CCnnFmmM1, or CCnnFmmM1A1 where,
nn is the Graphic Field to set
mm is the GPS data field to copy
