4.4.4 Ethernet and IP Addressing
Ethernet 10/100 is provided either through the standard Ethernet RJ45 Jack or as Ethernet RMII
signal lines through the Ethernet Mezzanine Connector (J8). As such, the RMII signals cannot be
interfaced to directly. The user must provide a carrier board and an Ethernet PHY chip. The PHY
chip should be configured for Address 1.
The communications rate through this interface is limited not only by the Ethernet 10/100 protocol
but also by the processing capability of the connected computer and various system overheads.
The IP address of a unit is assigned in one of two ways. If the P330 came as part of a Development
Kit then the IP addresses will be set at the factory to 192.168.1.x, where “x” is indicated on a label
mounted on the P330’s RJ45 jack. If the P330 was ordered as an “Industrial Module” then the IP
address is normally set to 192.168.1.100. The RangeNet GUI gives the user the ability to change the
IP address or to select the Dynamic Host Configuration Protocol (DHCP). Upon special request and
in conjunction with volume orders, Industrial Modules can alternatively be shipped using DHCP.
As a side note, the Node ID of the P330 is set in a similar fashion. If the P330 came as part of a Kit
then the Node ID will be set to “x.” If the P330 came as an Industrial Module, then the Node ID is set
at the factory and can be determined through the API or the RangeNet GUI provided with the system.
When using the GUI, the Serial Number shown on the Status Info Tab will be identical in value to the
Node ID. However, the Status Info Tab shows the value in hexadecimal while the Node ID is shown
in decimal.
Instructions on how to connect to the P330 via Ethernet or change the IP address and Node ID are
provided in the documents 320-0338 P330 RangeNet User Guide.
