Appendix C—Optional Communication Cards222 Power Xpert C445 Global Motor Management Relay MN042003EN—January 2019 www.eaton.comEthernet Communication Card and DIPSwitchesWhen an optional Ethernet card is connected to a C445,the DIP switches on the Base Control Module are dedicatedto determining the IP address of this card per the diagrambelow.If the C445 Base Control Module also includes the optionalRS-485 Modbus serial port, the node address and the datarate for this port must be configured using the Web Pages orthe inControl Configuration Software.DIP Switch settings on the C445 Base Control Module whenan Ethernet Card is installed.DIP Switch 10 is reserved for future use.Figure 132. Base Control Module DIP Switches withEthernet CardDescriptionsWhen switch 9 is OFF:Low Octet: DIP Switch numbers set low octet of static IPaddress 192.168.1.X where X is 0 – 253Ethernet Port SettingThe lower 8 switches (1-7) are each given a value based onweighted binary. If the switch second from the top (9) is Off,the 8 lower switches are provided a value from the bottomup as follows: 1, 2, 4, 8, 16, 32, 64, 128. The switches areturned On when they are pushed to the right. Add the valueof all switches that are On to determine the overall value.This value represents the low octet of the IP address192.168.1.x. This is an easy way to configure the EthernetCard to a known IP address so a computer can be configuredto easily and quickly communicate with the C445 via ModbusTCP Ethernet with the inControl software tool. Then, usingthis tool, the C445 Ethernet Card may be configured with anystatic IP address. Information on how to go online with theC445 using the software tool and Modbus TCP may be foundin the inControl software user manual. The followingprocedure indicates a procedure using the software tool toset a static IP address, subnet mask and gateway address forthe C445 Ethernet Card.1. Set DIP Switch 9 to OFF.2. Set the bottom 2 DIP Switches (1-2) ON and leave theothers OFF resulting in a value of 3 and an IP address of192.168.1.3 assigned to the Ethernet Card.3. Power cycle the C445 so the new DIP Switch settingswill be used.4. Using the inControl software, go online with the C445via Modbus TCP and the Ethernet Card.5. Under the Communications/Ethernet categories in thesoftware tool, configure a static IP address, subnet maskand gateway address. These will not take effect until asoft reset is issued to the C445 or until it receives apower cycle.6. Go offline with the C445 in the software tool.7. Set the DIP Switches so only the following switches areON: 2 and 9. The Ethernet Card will now be configuredfor “NV Static IP Address”.8. Issue a soft reset or power cycle the C445. When itpowers up the Ethernet Card will be configured with thestatic IP address, subnet mask and gateway address itwas configured for with the inControl software tool.9. This same process could be accomplished using theUSB port or the RS-485 port with the inControl softwaretool.
