CCFC Field Camera
A-1
camera. Files Manager allows the user to specify a name for the
files and the number of files kept in a ring memory type fashion.
The format of the Files Manager setting is as follows:
(AAAA,DDD:NAME.EXT,NNNN)
AAAA – camera PakBus address.
DDD – destination drive on the CR1000
USR for the user drive.
CRD for the compact flash memory card.
NAME – any name string that will be used to name the
files.
EXT – the file extension of the incoming file must match.
In the case of the camera, this must always be either jpg or
avi.
NNNN – number of files kept in the memory ring. This
number must be low enough so that the memory required
for files is less than what is available in the corresponding
drive. Otherwise, the USR memory will not ring, but will
fill up and stop. For the internal USR drive of a datalogger
this would normally be between 3 and 10 photos and for
an external memory card (i.e. CRD drive) the number of
photos can be larger. When communicating to retrieve
photos, it is suggested to limit the number of files in the
ring memory to 200 in order to avoid long communication
delays.
Following is an example of Files Manager settings:
(55,USR:SkySouth.JPG,3)
Camera PakBus address is 55
The files will be stored in the USR: director with a name
SkySouth####.jpg where #### is an incrementing number.
Entering a zero for this parameter will disable the
automatic numbering and produce a fixed file name.
The 3 most recent files will be kept. A new incoming file
will cause the oldest to be deleted.
18.3 CR1000 COM Port (Control Port) Communications
On the CR1000, a pair of control ports can be configured to
function as RS-232 communication (COM) ports. Any of these 4
COM ports can be configured as PakBus ports and used to
communicate with the camera.
