NovaRoam EH900 User Manual Regulatory Information FCC Warning This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions: 1) This device may not cause harmful interference and 2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications to this device without the express written consent of Nova Engineering, Inc. may void the user’s authority to operate the device.
NovaRoam EH900 User Manual • The cable run for the selected antenna must exceed the minimum length quoted in this User Manual. • All persons must maintain a minimum separation of 12" (30.48cm) from any NovaRoam EH900 antenna. You should disconnect the AC/DC input power source from the NovaRoam EH900 whenever repositioning the antenna. You are responsible for taking the necessary steps to ensure that these guidelines are communicated to all persons that may come near the NovaRoam EH900 antennas.

NovaRoam EH900 User Manual Appendix A: Example Network Plan The use of private IP addresses is strongly recommended when configuring a NovaRoam network. The following example of a NovaRoam network uses several private IP subnets from the 192.168.0.0 block of private addresses. The NovaRoam network depicted in Figure 37 contains three Ethernet segments. The first segment uses the 192.168.200.0 Class C subnet, encompassing a range of addresses from 192.168.200.1 to 192.168.200.254.
NovaRoam EH900 User Manual Once the individual networks are established, it is recommended that you plan an IP addressing scheme. In the example from Figure 37, each NovaRoam host ID is 1, while the computer’s host ID is 2. Following a numbering scheme such as this will make it easier to keep track of which IP addresses are used for each device. The wireless network in the example uses the 192.168.203.0 subnet. This subnet is different than the subnets used for the Ethernet segments.
NovaRoam EH900 User Manual Appendix B: Routing Options The NovaRoam Mobile Router provides a wireless connection between two or more separate Ethernet subnets. Data is then routed between the Ethernet subnets. Route information can be entered manually, or can be handled automatically by AODV, the NovaRoam’s Mobile Ad hoc Networking (MANET) algorithm. Choosing Routing Mode As a router, the NovaRoam provides a wireless connection between two or more separate Ethernet subnets.
NovaRoam EH900 User Manual A third option is Multihop mode. In Multihop mode, all packets originating from the NovaRoam are designated as multihop packets. Any NovaRoam receiving a multihop packet will automatically repeat the packet. Multihop mode can be used in conjunction with other routing modes. Using Static Routes Figure 38 is an example of a point-to-point NovaRoam network. In this example, Subnet 1 has been assigned the 192.168.1.0 Class C subnet, while Subnet 2 has been assigned the 192.168.2.
NovaRoam EH900 User Manual gateway. It is also necessary to add static routes within each NovaRoam. The NovaRoam from Subnet 1 must have a static route to Subnet 2, using the wireless interface of the NovaRoam from Subnet 2 as the gateway. The route should be set up like this: 192.168.2.0 Network 255.255.255.0 Netmask 192.168.3.2 Gateway 1 Metric It is recommended that all hosts from Subnet 2 use 192.168.2.1 as their default gateway.
NovaRoam EH900 User Manual RREP back to the source node. Otherwise, it rebroadcasts the RREQ. Nodes keep track of the RREQ's source IP address and broadcast ID. If they receive a RREQ that has already been processed, they discard the RREQ and do not forward the packet. As the RREP propagates back to the source, nodes create forward pointers to the destination. Upon receiving the RREP, the source node will begin forwarding data to the destination.

NovaRoam EH900 User Manual Appendix C: Using NovaFind NovaFind is a utility designed to discover NovaRoams on a network. After a NovaRoam has been located, you can obtain or change a NovaRoam’s IP address or Netmask. NovaFind does not require installation. Simply locate the NovaFind folder on the NovaRoam CD. Copy the file named NovaFind.exe to your local hard drive. NovaFind can also be run directly from the NovaRoam CD. To Start NovaFind, double-click on NovaFind.exe.
NovaRoam EH900 User Manual Press the Find button. Any NovaRoams on the wired network will be displayed. NovaRoams will be listed by MAC address, current IP address, and Netmask. To select a NovaRoam from the list, click on the NovaRoam in the MAC address column. After selecting a NovaRoam from the list, the IP address or Netmask can be changed. Once selected, change the current IP address or Netmask to the desired address or Netmask in the appropriate fields.
NovaRoam EH900 User Manual Appendix D: Antenna/Cable Requirements The NovaRoam EH900 must be installed by a professional in order to comply with FCC Part 15 radiated power limits. Furthermore, only antennas supplied by Nova Engineering may be used with the NovaRoam EH900. The FCC mandates that the Effective Radiated Power (ERP) may not exceed +36 dBm. This is equivalent to a NovaRoam EH900 running at full output power (1 watt/+30 dBm) with a +6 dBi antenna.
