CC5MPX Digital Camera
80
The MD485 is useful for connecting more than one camera to a datalogger or if
long cable lengths are involved. If multiple cameras are connected to an
MD485, then it would be beneficial to offset the capture times of the images so
that only one camera is attempting to transmit a file at any given time.
The camera can download images or video via an RS-485 port using PakBus.
An MD485 is required to interface the camera to a datalogger. The following
items are required for RS-485 PakBus communications and can be confirmed
by either the web interface of DevConfig (FIGURE 8-44 ):
•
Confirm that the PakBus port parameter of the Communications
Setting is reading RS-485.
• Set the RS-485 baud rate to match the baud rate of the device being
connected to the camera.
•
Set the parameter PakBus Address of Communication Settings to a
unique value in the PakBus network.
• Set the parameter PakBus Destination Address of the device that the
camera needs to send images to.
•
Include PakBus Security Code, as required.

8.8 PakBus® Communications
The camera uses PakBus to send image files from the camera to the datalogger
or other PakBus compatible devices. The LoggerNet tool PakBus Graph can
be used to change the configuration of a camera. The use of the PakBus
Graph is discussed in Section 8.8.2 ,
