MEA VMM User’s Guide 1 Vehicle Mounted Modem 1.1 Introduction Thank you for purchasing the MEA Vehicle Mounted Modem (VMM). MEA is a wireless communication system capable of supporting high data rate mobile communication at variable rates of vehicular speeds. The VMM (VMM6300) is a wireless modem that has been designed for permanent in-vehicle mounting.
MeshNetworks 2 Installation Requirements NOTE: All Intelligent Access Points (IAPs) on the MEA network require a software upgrade to support VMM Devices. The MEA Vehicle Mounted Modem External will require the following in a typical installation: 2.1 • 12 VDC Power from vehicle or other direct current power supply • A Hub or Switch (if more then 1 Ethernet device will be used) • Antenna and RF cabling appropriate for use in the 2.4 Ghz band.
MEA 2.2 VMM User’s Guide Record MAC Address of the VMM6300 The transceiver and SBC (Ethernet) MAC addresses are recorded on the label located on front side of the VMM unit. Record these numbers in the MAC Address Table in Section 3.3.1, because they will be required later to configure and provision the device. Figure 2-1 2.3 VMM6300 Identification Label VMM6300 Assembly The VMM6300 Assembly shows the external connection points on a VMM6300 box.
MeshNetworks Install the VMM using the following procedure: 1. Mount the VMM box in a suitable location in a vehicle. The device is not water proof. The device should be reasonable protected from moisture and other exposed outdoor environments. Refer to the mounting procedure in the assembly section of this document. 2. Connect the antenna to the N-type connector . 3. Insert the Power Plug into Power Connector. 4. Verify the MAC address and ETH address has been recorded in Section 3.3.
MEA VMM User’s Guide 2. Obtain the transceiver MAC address and the ETH address that was recorded in Section 3.3.1. The address will be in the format 00-05-12-0A-xx-yy for the transceiver and 00-05-12-30-xx-yy for ETH. 3. From MeshManager, display devices using the MAC address. 4. Select the appropriate VMM in the device tree, and then ping the device (right click and select ping). A successful response to the ping command verifies that the VMM is communicating to the infrastructure devices.
MeshNetworks 3 Installing the MEA Vehicle Mounted Modem 3.1 Device Administration: Configuring the VMM Devices The VMM provides network access to one or more IP devices connected to the Ethernet port of the VMM. In order for the VMM to provide service to the IP devices, some configuration must be done prior to connecting the IP devices. The VMM serves as a default gateway for the attached IP devices.
MEA VMM User’s Guide Figure 3-1 Enter Network Password Initial Web Page Authentication Dialog The username is admin, and the default (initial) password is admin. The password for the admin account should be changed during installation. The device has two accounts for the web pages - an administrative account (username:admin, default password:admin), and an access account (username: monitor, default password: monitor).
MeshNetworks After the login authentication has been completed, the web browser will display a redirecting page, and your browser will automatically transition to the home web page for MEA Device Administration. Figure 3-2.

MEA VMM User’s Guide Field Name Field Description Field Default Value RDATE Server IP Address The IP address of the RDATE server. This is 172.31.0.20 usually the MiSC when operating in infrastructure mode. The RDATE server provides the current date to the VMM. The VMM can operate without an RDATE server.
MeshNetworks DHCP server and the inclusion of a DHCP server in the core network configuration to answer these requests. With Network DHCP selected, the VMM will send DHCP requests for its own address to the core network once it becomes associated and establishes communications with the infrastructure. The server may be configured by the operator to hand out temporary or static leases. The VMM must associate and acquire an address from the network before establishing communications.
MEA VMM User’s Guide All of these schemes may be assigned per device, either by the user or by the network manager. The network manager can also limit the user-selectable schemes or force a specific scheme. Devices in each of these schemes can interoperate and communicate with each other, so long as the assigned addresses do not conflict and are mutually routable. 3.1.2.
