CCFC Field Camera
20
3 Single Pole 16-20AWG Grey Push Operated Connector
Terminals.
Maximum recommended cable length is 20 m (65 feet).
Longer cable lengths can be used; however, a user-supplied
heavier gauge of wire is suggested. It is recommended that the
individual wire resistance on the 12 Vdc and Ground conductors
not exceed 0.7 Ohms. Using a longer cable in conjunction with
RS-232 communications requires slower BAUD rates. Depending
on the cable length and type of cable, RS-232 may not be suitable
for communications and the use of RS-485 should be considered.

8.3 Ethernet Cables
The
CCFC
does
not
support
the
PakBus
communication protocol over Ethernet.
The Ethernet connection can be used to configure the camera
settings as well as for targeting and focusing the camera. The
Ethernet port of the CCFC is auto MDIX; therefore, an Ethernet
crossover cable is not required when connecting the camera to
other devices.
A standard CAT5 (or better) Ethernet cable with RJ45 connectors
can be used to interface to the camera in indoor conditions or for
temporary connection outdoors when conditions permit. When an
Ethernet connection is required for permanent outdoor
installations or when a connection to the camera is required in wet
or harsh conditions, the Environmental Ethernet Cable
(CCFCCBL2-L) assembly needs to be used. Campbell Scientific
Canada recommends the use of the environmentally sealed cable
at all times when outdoors.
The Environmental Ethernet Cable assembly provides one end
with an environmental connector that provides a weather proof
connection when properly mated to the camera. The other end of
the cable consists of a standard RJ45 connector. The
Environmental Ethernet Cable is meant to provide an Ethernet
connection between the CCFC and a local network, router,
cellular modem, or laptop.
