Determine how many AE channels will be needed for inspection and how many of the 4 and 16 channel units can serve them. Think on number of environmental parameter channels and digital in/out control signals, too. Accordingly, set all devices with the proper module codes.
Set the IP address of the “leading” device for matching the local network. For all other units, set the IP address to default.
Connect the “leading” and, if necessary, some “midway” devices to a suitable power supply. Enable the power supply output to the expansion port(s) where needed.
