CC5MPX Digital Camera

Figure 9-3 Datalogger Connections with RS-232

10. RS-485 Communications

The optional RS-485 communication interface of the CC5MPX can be used in

conjunction with the MD485 to interface a datalogger to 1 or more cameras. Refer

to the MD485 Manual for additional information.

The MD485 is useful for connecting more than 1 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 1 camera

is attempting to transmit a file at any given time.

The camera can download images or video via an RS-485 port using the PakBus

protocol. 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 the Device Configuration Utility:

x Confirm that the PakBus port parameter of the Communications Setting is

reading RS-485.

x Set the RS-485 BAUD rate to match the BAUD rate of the device being

connected to the camera.

x Set the parameter PakBus Address of Commincation Settings to a unique

value in the PakBus network.

x Set the parameter PakBus Destination Address of the device that the

camera needs to send images to.

x Include PakBus Security Code, as required.
