After connecting the camera to a power source, turn the power switch to the
ON position and verify the proper LED sequence (Section 3.7) before
connecting the camera for communication.
Standalone mode records images to a flash card installed in the camera and
has no connection to a logger. Capturing images in Standalone mode requires
the use of a FAT16 formatted Compact Flash Memory Card (Section 3.8). The
only wire connections to the camera are the power supply wires (ground and
+12 V) that connect to a 12 VDC source.
The recommended cable for use with the camera is a 3 pair individually
shielded 24 AWG cable. The cable part number is 9721 and the Model number
for a finished cable is a 9721-L (L is the required length in feet). Only shielded
cable should be used with the camera for proper operation. It is recommended
to use the cable supplied by Campbell Scientific, as the cable is of high quality
and well suited for communication between the camera and datalogger.
The individual conductor colors and their connections are outlined in Table 1.
Following the recommended color scheme is not mandatory and users may be
required to select their own color schemes for cables with different color
arrangements.
The maximum recommended cable length of 24 AWG cable is 30 Meters (98.1
feet). Longer lengths can be used, however a heavier gauge of wire is
suggested. It is recommended that the individual wire resistance on the
+12VDC and Ground conductors not exceed 2.7 Ohms. Using longer cable in
conjunction with RS-232 communication will require slower BAUD rates.
Depending on the cable length and type of cable, RS-232 may not be suitable
for communication and the use of RS-485 should be considered.
2.2 Configuring
The camera uses PakBus protocol to send image files to the datalogger and
both must be configured to enable communication. The RS-232 port is used in
conjunction with the Device Configuration software to change settings and
operating parameters in the camera (Section 5). Device Configuration Utility
is a free download from any Campbell Scientific website.
