2.7.2.1 DC Power/Ignition Sense Interface
The terminal is designed to use +10 to +30 Volt Direct Current (VDC) negative ground
vehicle power systems. For safety, the EXPLORER 122 Terminal should be installed in a
circuit with an inline 7.5 A fuse that will trip during extended overcurrent events.
The nominal power consumption when receiving is approximately 9 Watts (W). During
transmission bursts or terminal boot up, the power draw can be up to 48 W.
The EXPLORER 122 Terminal power on/off is controlled by the ignition sense line using
internal software, rather than a hard on/off switch on the red power line. Connect wires to
the battery and ignition switch as shown in the power harness wiring diagram.
EXPLORER 122
User Manual
98-150578-A 2-7

• When the ignition sense line is pulled low (less than 2 V), the EXPLORER 122 Terminal
performs a controlled shutdown sequence (under software control), de-registering and
saving any relevant operational data before powering off.
• When the ignition sense line is pulled high (5 to 30 V) or left unconnected, the EXPLORER
122 Terminal powers on.
CAUTION: Do not apply an input voltage to the terminal outside of the
specified range. This will permanently damage your terminal.
CAUTION: Observe proper Electro-static Discharge (ESD) practices during
installation.
The terminal protects against continuous inputs of -32 VDC to +32 VDC. Applying an input
voltage outside this range may permanently damage the terminal and cause it to become
non-operational.
2.7.2.2 Ethernet Interface
The Ethernet interface is defined by IEEE 802.3 for operation in 10Base-T and 100Base-TX
modes with the exception of the connector type. Cabling for Ethernet connectivity must
meet ANSI/TIA/EIA-568-A specifications for Category 5 or Category 5e cables. It is
recommended that the wired Ethernet interface be used for permanent installation. Contact

3.4.2 DHCP Server
There are two options for DHCP server configuration: dynamic and static (Figure 3-6).
Dynamic Assignments
The DHCP server can be configured with a pool of IP addresses that it will lease to clients.
The Pool Start and Pool End fields are set to the start and end IP addresses. The Netmask
field is set to the subnet mask that a client should use. Each of these fields must be a valid IP
address or subnet mask in dot notation (a.b.c.d).
The lease time is the time in minutes that a lease given to a client will be valid.
Static Assignments
The DHCP server can also be configured to provide a static IP address to a particular
network device. The network device is determined by its hardware MAC address. Each time
the DHCP server gets a request from a device that matches the MAC address the assigned IP
address will be given to the device.
The Name field is the hostname of the network device that will be assigned a static IP
address. This name must not contain any white space and should consist of alphanumeric
characters, hyphens or underscores. The MAC Address field is set to the MAC address of the

3.4.3 Port Forwarding
The terminal provides a network address translator (NAT) that creates a private network for
devices attached to the terminal. Devices behind the terminal NAT are invisible to any hosts
outside the terminal NAT.
The only way to access a device behind the terminal is either:
• Have the device behind the terminal initiate the connection
• Create a port forwarding assignment to the device in the terminal
Port forwarding allows incoming UDP or TCP packets destined for a specific port to be
forwarded to a network device (client or host) “behind” the terminal NAT. The incoming
packet will be forwarded to the destination port and IP address defined by the port
forwarding rule. Using port forwarding assigns the port being forwarded to a single host IP
address and excludes this port from being used by any other host.
CAUTION: Modifying port forwarding settings can result in loss of
connectivity to the network. See Section 4 for details on network
configuration and examples.
EXPLORER 122
User Manual
98-150578-A 3-11
Port Forward Assignments

Assignments table (Figure 3-11).
To add a port forwarding configuration, enter the following information into the Port
Forwarding table:
1. Name – Set to the logical name of the service being forwarded. This name must not
contain any white space and should consist of alphanumeric characters, hyphens or
underscores.
2. Incoming Port – Set to the port number of the service to be forwarded, such as 21 for
FTP.
3. Protocol – Select between UDP/TCP/Both.
4. Server IP – Set to the IP address, in dot notation, of the host that the packets will be
forwarded to.
5. Server Port – Set to the port number on the Server IP that the packets will be sent to.
This port can be the same as the Incoming Port, but does not need to be.
6. When complete, click Add and the assignment will show up in the Port Forwarding
Assignments shown in Figure 3-11.

Appendix A - Power/Ethernet Cable Assembly Instruction
This section provides guidelines for the Value-Added Resellers or end-user to assemble the
power/Ethernet cables. The solder cup connector kit ships with the terminal.
A.1 Required Tools
The following tools are required to assemble the power/Ethernet cable:
• Utility knife or similar
• 18-26 AWG wire stripper
• Diagonal cutters
• Long-nose pliers
• Soldering iron and solder
A.2 Connector Pinout Information
The figures below show the connector and cable wiring diagram.
P1 Connector
P2 Connector
A.3 Cable Specification
The cable selection for this application is influenced by three main principles: current
capacity, outdoor application and shielding.
EXPLORER 122
User Manual
98-150578-A A-2
The operating input voltage range for the terminal is 10 to 30 VDC and draws a maximum of
4.8 amperes. If the application requires an extended cable length, it is necessary to calculate
the cable voltage drop to determine if the terminal is able to receive the minimum 10 volts
for operation. 18 AWG wire is recommended for both power and ground wires.
Exposure to outdoor elements can degrade the insulation of the cable and allow moisture to
penetrate the conductor and subsequently degrade the copper conductor. It’s highly
recommended that the cable chosen shall be able to withstand UV rays.
Cable shielding is a critical design element over long distance. The cable selection can
adversely be affected by EMI/RFI/ESI. The cable carries both power and Ethernet data. The
data lines should be twisted pair and shielded.
The recommended cable composition is described in the picture below. The overall cable
diameter should be less than 9.50 mm in order to fit in the connector backshell.
