1.5 Replacement Parts This product is not field-serviceable, except by the replacement of a complete unit. Specialized equipment and training is required to repair the processor and radio boards. Contact Technical Support for service information before returning equipment. A Technical Support representative may suggest a solution eliminating the need to return equipment. 1.5.1 Factory Repair When returning equipment for repair, you must request an RMA (Returned Material Authorization) number.
2. Installation 2.1 Planning the Installation 2.1.1 Overview To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum position for GeminiG3 unit and its antennas as well as the routing of all associated cabling and wiring. 2.1.2 Location Often, installations in cars are done in the trunk, underneath the back window ledge or on the trunk floor. In vans and small trucks, it is usually done in the back of the vehicle.
2.2 Warnings Before starting installation, review all of the following warnings. 2.2.1 RF Radiation warning Recommended safety guidelines for the human exposure to radio frequency electromagnetic energy are contained in the Canadian Safety Code 6 and the Federal Communications Commission (FCC) Bulletin 65. Proper installation of the transceiver antenna of GeminiG3 radiomodem as summarized in section 2.5 will result in user exposure substantially below the recommended limits for the general public.
2.3 Physical Unit 2.3.1 Recommended tools and supplies • • • • • Electric drill for mounting holes Hammer and center punch Tie-wraps Drills and circle cutters as needed according the size of screws (or nuts and bolts) used. In-line “Power meter” capable of measuring forward and reflected power at the operating frequency of the radio. 2.3.
2. Using the installation bracket as a template, mark the four locations for drilling (see Figure 1). Again, ensure that drilling at the selected points is safe and will not cause damage. 3. Indent the drilling positions with a center punch. 4. Drill holes sized for the self-tapping screws or for the nuts, bolts and lock washers used. Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal. 5. Install the bracket without distorting (see Figure 2).
2.4.2 Routing of power cable 1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the customer, vehicle manufacturer, agent or supplier. Note: In this event, exercise extreme caution throughout the installation and fit the fuse only when the installation is complete. 2. The 22 feet (6.7 meters) long power cable consists of three wires attached to a Packard Electric “Weather-Pack” connector (DC power Connector, see Figure 4). 13.
• In installations equipped with a “ChargeGuard”, connect to the controlled-side of the ChargeGuard (remembering that the DC Power lead must NOT be switched). 10. Make appropriate connections. Cautions: Where scraping to bare metal was required, and at the battery posts where wire ends and lugs may be exposed, apply anti-corrosion compound. Insert the fuse only when installation is complete and ready to test. 11. At the GeminiG3 radiomodem’s position, neatly coil cable slack and attach securely. 2.
2.5.2 Planning Referring to Figure 5, the GeminiG3 radiomodem commonly uses three separate antennas: • “T” - Main transceiver Constraints are the limit of 50 cm (see section 2.5 above) and omni-directional factors • “R” - Auxiliary receiver – Constraints are the receiver spacing of at least 5/8 λ (wavelength) from transceiver antenna and omni-directional requirements • “G” - Global Positioning System (GPS) Constraints are TX spacing of at least 24-in/60.
2.5.3 Antenna Installation 1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions to the position where the GeminiG3 unit is mounted. 2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna used and make the connection. 3. At the GeminiG3 unit position, cut the three cables to length and terminate with the appropriate plug.

Lease Start Address Lease Duration Pool of addresses allocated for DHCP purpose. If a unit is configured as DHCP Server, this field represents the start IP address pool managed by the DHCP Server. Normally, GeminiG3 radiomodem automatically calculates the Lease Start Address (equal to Ethernet IP Address plus one). The period over which the IP Address allocated to a DHCP client is referred to as a “lease”. Lease Duration is the amount entered in minutes. A value of “0” indicates an infinite lease.
4.7.3.5.1 NAT Overview The purpose of the “Network Address Translation” (NAT) protocol is to hide a private IP network from a public network. The mechanism serves both as a firewall function and to save IP address Packet (1) Source Address 172.30.1.2 Destination Address 192.168.1.2 Packet (1) Source Address 192.168.1.1 Destination Address 192.168.1.2 192.168.1.1/24 172.30.1.1/24 Host 1 172.30.1.2/24 Host 2 192.168.1.2/24 NAT Enabled Device Packet (2) Source Address 192.168.1.
4.7.3.5.1.1 NAT on the Base Unit (Paragon3) The Paragon3 unit is equipped with a management port (the Ethernet 2 interface). When NAT is enabled on the Paragon3 unit, the network covered by the Ethernet 2 interface is considered private.

4.7.3.5.1.2 NAT on the Mobile Unit (GeminiG3) When NAT is enabled on a GeminiG3 unit, the network covered by the Ethernet interface is considered private. In the following example, NAT is enabled on a single mobile. External Network Management Host 1 172.30.1.2/24 External Host 1 200.1.1.1/24 Ethernet 1 192.168.1.1/24 Management Network Public Network (External Network + RF Network + Mobile 2 Network + Management Network) Base (Paragon3) RF 10.0.1.1/24 Ethernet 2 172.30.1.
4.7.3.5.2 SNMP Overview SNMP (Simple Network Management Protocol) is used by network management systems to manage and monitor network-attached devices. SNMP is based on the manager/agent model consisting of a manager, an agent, a database of management information, managed objects, and the network protocol. The manager provides the interface between the human network manager and the management system. The agent provides the interface between the manager and the physical devices being managed (Figure 28).

4.7.3.6 Setup (Advanced) ► IP addressing For a more detailed description of the broadcast and multicast features of the GeminiG3 radiomodem, please refer to paragraph 4.7.3.6.1 below.
4.7.3.6.1 IP Broadcast/Multicast Overview When an IP packet needs to reach more than one unit, the destination address can be set to either a broadcast address or a multicast address. 4.7.3.6.1.1 Broadcasts Figure 32 - Broadcast Window Detail There are two types of IP broadcast addresses: • Directed broadcast A directed broadcast address is an IP address where the host portion is all ones (for instance 172.30.1.255 is the directed broadcast address for the network 172.30.1.0/24, 172.30.1.
Note: Occasionally, the unit cannot determine that the packet is actually a directed broadcast. In such a case, the packet is normally routed. Example (Directed Broadcast forwarding enabled) Send to 172.30.1.255 Sender Base (P3) Directed broadcast forwarding enabled 10.0.0.1/8 RF Airlinks 10.0.0.2/8 Directed broadcast forwarding enabled 10.0.0.4/8 Mobile (1) 172.30.1.1/24 Mobile Host(1) 172.30.1.2/24 Mobile Host(2) 172.30.1.3/24 Mobile (2) 172.30.3.1/24 Mobile Host(3) 172.30.1.
Example (Directed Broadcast forwarding disabled) Send to 172.30.1.255 Sender Base (P3) Directed broadcast forwarding enabled 10.0.0.1/8 10.0.0.2/8 Directed broadcast forwardMobile (1) ing disabled 172.30.1.1/24 10.0.0.4/8 Mobile (2) 172.30.3.1/24 Figure 34 - Example of Directed broadcast forwarding disabled In this example (Figure 34), directed broadcast forwarding is enabled on the Base unit and disabled on the Mobile (1) unit. If Sender sends a packet to destination address 172.30.1.
Example (Limited Broadcast forwarding enabled) Send to 255.255.255.255 Sender Base (P3) Limited broadcast forwarding enabled 10.0.0.1/8 RF Airlinks 10.0.0.4/8 10.0.0.2/8 Limited broadcast forwarding enabled Limited broadcast forwarding Mobile (2) enabled 172.30.3.1/24 Mobile (1) 172.30.1.1/24 Mobile Host (1) 172.30.1.2/24 Mobile Host (2) 172.30.1.3/24 Mobile Host (3) 172.30.1.4/24 Mobile Host (4) 172.30.3.
Example (Limited Broadcast forwarding disabled) Send to 255.255.255.255 Sender Base (P3) Limited broadcast forwarding enabled 10.0.0.1/8 RF Airlinks 10.0.0.4/8 10.0.0.2/8 Limited broadcast forwarding disabled Limited broadcast forwarding Mobile (2) enabled 172.30.3.1/24 Mobile (1) 172.30.1.1/24 Mobile Host (1) 172.30.1.2/24 Mobile Host (2) 172.30.1.3/24 Mobile Host (3) 172.30.1.4/24 Mobile Host (4) 172.30.3.
4.7.3.6.1.2 Multicast IP multicast addresses are in the range 224.0.0.0 to 239.255.255.255. These addresses are used to represent logical groups of units that may or may not reside on the same networks. Multicast is used when “one-to-many” communication is required. For instance, a radio station might offer a music channel on the Internet in real time.
In the E-DBA environment, an outside sender-host might be interested in sending multicast packets to any one of the following groups: • “All Base” group (not currently supported) • “All Mobile” group (DMP-IP only) • Various “Mobile Host” groups. The Base (P3 in the illustration) units are directly connected to the outside network.
The following setup example would allow the “Sender” unit to communicate with different multicast groups. The settings for mobile and base are shown in Figure 40 below. Also represented in Figure 41, it would enable the Sender unit to reach all entities of the various groups.
4.7.3.7 Setup (Advanced) ► IP Optimization & Tuning Figure 42 - Advanced IP Configuration - IP Optimization & Tuning - OIP Item Description RF ACK Disabled, Enabled (Default) OIP Retries Number of OIP retries.
4.7.3.8 Setup (Advanced) ► Time Source To facilitate tracking of events in a network, the Paragon3 base station and the GeminiG3 radiomodem can initialize their real-time clocks using a number of protocols. At reset time, the Paragon3 base station can use the SNTP protocol (RFC2030) to pick up the current UTC (Universal) time. Setting the “TimeZone” and “Daylight Savings” options allows displaying the correct local time in the “Unit Status” web page.
4.7.3.
4.7.4 GPS All GeminiG3 radiomodems shipped from the Dataradio factory are fitted with a 12-channel high efficiency GPS receiver, equipped with WAAS feature for better location precision (<3 meters). GPS "strings" are collected from embedded GPS receiver in the GeminiG3 mobile radiomodems. The strings are converted into DCF 2.0 ("Dataradio Compressed Format, version 2.0") reports and provided to both local and remote delivery services.
4.7.4.
Item Local Port Description Read-only field – Indicates port configured for the IPSD. Note: IPSD should be enabled in Setup (Advanced)-> IP Services Provides a Drop-down box for selecting the appropriate GPS report format for the Local IPSD.
4.7.4.3 GPS ►AAVL The “Autonomous Automatic Vehicle Location” (AAVL) feature adds the ability for GPS-equipped GeminiG3 models to initiate "Here I am" position message transmissions. AAVL allows the system designer to specify the maximum distance or the time interval between position reports: If the vehicle moves more than a specified distance since its last report, a new position report will be generated.
4.7.5 Security 4.7.5.1 Password and Encryption Control The Setup web pages, the CLI (command line interface) and the FTP server all require a password to prevent unauthorized users from changing a unit’s configuration. At the time of manufacture, the password is set to “ADMINISTRATOR” (all uppercase) but Dataradio strongly suggests that the password be changed as units are installed.
4.7.6 Statistics 4.7.6.1 Statistics ► Interfaces Note: All definitions given below use the following convention: • RX (or Input) = data received from a lower network layer • TX (or Output) = data transmitted to a lower network layer Figure 49 - Statistics - Interfaces Item Description The LAN (Ethernet) Interface layer shows reception and transmission traffic counts. RX Pkts (ETH1) The total number of input packets received by Ethernet 1 interface.
4.7.7 Maintenance 4.7.7.1 Maintenance ► Ping Test To aid in trouble-shooting IP connectivity issues, the Paragon3 base station and the GeminiG3 radiomodem can transmit ping packets to a given IP address. Four packets are sent and the time taken for each to reach the destination and return is displayed.
