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.
2.1.1 Standalone Mode
Standalone mode records images to a CompactFlash card installed in the
camera and has no connection to a logger. Capturing images in standalone
mode requires the use of a FAT16 formatted CompactFlash 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 (see Section 2.1.2).
2.1.2 Power and Pulse Connections
The CABLE3CBL-L cable is typically used to connect the camera to the power
source and a datalogger control port (see Table 1b). The datalogger control
port is used if the datalogger will trigger image acquisition.
It is essential that the ground cable be connected first. CAUTION

2.1.3 Datalogger and MD485 Multiplexer Connections
If the distance between the camera and datalogger will be less than 25 ft
(7.6 m), the camera typically connects to the datalogger via the COMCBL1-L
cable. Campbell Scientific recommends using the MD485 multiplexer if the
distance between the camera and datalogger needs to be more than 25 ft
(7.6 m). Detailed information about using the camera with a datalogger or
multiplexer is provided in Section 4.
