CC640 Digital Camera
remove the memory card, and delete the “NEWCODE.HEX” file using a PC if
no other cameras need to be updated. Leaving the file on the memory card will
cause the camera to repeatedly update its firmware every time the camera
wakes up from its quiescent mode.
3.9 CS I/O and RS-232 Connections
For configuration and communication, two 10 pin (2 X 5) connectors are built
into the camera. The RS-232 port is designed to provide a 9 Pin DCE type
port. Part number C1947 provides a DB9 (sockets) connector that can be used
for CS/IO and RS-232 operation with the use of the COMCBL1, and
configuration with a straight RS-232 cable to the serial port of a pc.
4. Communication
4.1 PakBus Communication
The camera uses the PakBus protocol to send image files from the camera to
the datalogger or other PakBus compatible devices.
Communication is not enabled while the camera is in quiescent mode. This is
done to conserve power in its low power state. When an image file is ready to
be transmitted, the camera will initiate communication and send the JPEG
image via the selected PakBus port.
The camera is a PakBus Leaf node and is not capable of performing any
routing.
4.2 Connection Kit #19504
For convenience, part number 19504 is used to connect between the camera
and the CS/IO port of compatible loggers, or the RS-232 port of the CR800,
CR1000, or CR3000 loggers. It consists of a DIN rail mount, a length cable
(#17855) with a DB-9 (pins) connector to pigtails, and some DIN style
contacts. The kit mounts in the enclosure and provides a connection between
the COMCBL1-L and the 17855. See Figures 3, 4, and 5 below to understand
how to interconnect the two cables with the #19504. For this connection
method, ½” of insulation is removed from the wire to be inserted into the DIN
style connectors. The square holes and round holes are arranged in pairs and
the square hole associated with its corresponding round hole opens the contact
in the round hole where the wire is inserted. The round hole closest to a square
hole is a square hole/round hole pair.
