1.1 Introduction to the EXPLORER 122 Terminal
The EXPLORER 122 is the smallest auto tracking terminal in the EXPLORER range of satellite
terminals. It is a compact communications-on-the-move satellite terminal offering highly
reliable real-time IP data connectivity, and the possibility of using EXPLORER Push-to-Talk
and GPS tracking services across the coverage area.
Whether you’re engaged in emergency response, humanitarian operations, fleet
management or transportation, EXPLORER 122 is an easy deployable communication system
you can always rely on. Simply place the antenna on the roof of your vehicle and get access
to the Internet instantly.
The EXPLORER 122 Terminal uses ViaSat’s L-band Mobile Satellite Service (MSS), which offer
99.9% network availability. MSS provides encrypted connections with latencies below 800
milliseconds, and uses the high-performance Ligado satellite that covers North America.
The EXPLORER 122 two-way networking capability enables both real-time monitoring and
real-time control for a wide range of applications such as emergency first responders,
homeland security forces, disaster aid workers, correspondents, etc.

2Getting Started
2.1 Unpacking
The EXPLORER 122 Terminal is shipped in packaging materials that are uniquely designed
for the product. The following packing list describes the contents of a typical EXPLORER 122
shipment:
1. EXPLORER 122 Terminal
2. Mating Connector (assembly required)
Upon unpacking of the box, inventory the contents and inspect for sign of damages
during shipping. Contact your retailer in case of missing contents or noticeable defects.
To get started, the additional following items may be required:
3. Magnetic Mount (Platform Dependent)
NOTE: Contact your terminal integration partner for specific mounting
equipment.
2.2 Selecting Mounting Location
The EXPLORER 122 Terminal is designed for mobile vehicle installation. The terminal can be
permanently mounted with mounting screws or temporarily mounted with magnetic mounts
using the Installation kit (optional accessories).
Mounting location should be selected to provide the terminal with a clear line-of-sight to
the operational satellite without any obstructions from the vehicle. Figure 2-1 illustrates
improper vs proper placement of the terminal.
Terminal should be placed as far away from other transmit antennas as possible.
WARNING:Terminal antenna should be kept at least 44 cm from direct
exposure to humans.

2.3 Installation
The EXPLORER 122 Terminal is 250 mm long by 146 mm wide (excluding connector) and 62
mm high. The terminal is designed to be magnetically-mounted to a vehicular platform. Two
size M5 mounting holes for magnetic mounts are located on the underside of the terminal
as shown in Figure 2-2.
CAUTION:The “Caution” icon identifies procedures or factors that can
affect the installation and configuration of the system (may damage or
render equipment inoperable).
Figure 2-2. Terminal Mounting Hole Locations
The terminal should be installed with the connector facing the rear of the vehicle. An
example of installation with a rear facing connector is shown in Figure 2-3.
CAUTION:Do not over tighten.
CAUTION:Do not apply pressure to the cable/connector during the
installation.
CAUTION:Do not force the connector pins to mate since this may damage
the pins.

User Manual
98-150578-A 2-4
Figure 2-3. Terminal Mounting Example
2.4 Powering Up
The EXPLORER 122 Terminal is designed to automatically start up when DC power is applied
via an ignition sensor line. An ON/OFF power switch does not exist on the terminal.
At the completion of its power-up sequence, the terminal will automatically search for GNSS
and MSS satellite signals.
CAUTION:Do not stand in front of the unit once power is applied.
2.5 Obtaining a GNSS Fix
The MSS network does not require the terminal location to access the network. However,
terminal location enables optimal customer service.
At the completion of its power-up sequence, the terminal will automatically search for GNSS
and satellite signals. The default position reporting uses GPS satellites and the terminal will

EXPLORER 122
User Manual
98-150578-A 2-5
automatically attempt to get a new GPS lock every time it is powered on. Obtaining a lock
may take up to 5 minutes upon power-up.
2.6 Antenna Pointing
The EXPLORER 122 Terminal contains an electronically steerable antenna and does not require any
pointing by the user.
2.7 Connecting the EXPLORER 122 Terminal to Other
Equipment
2.7.1 Interfaces
The EXPLORER 122 Terminal offers the following wired interfaces via a multi-pin circular connector as
shown in Figure 2-4 and Table 2-1.
•DC Power
•LAN (Ethernet)
The EXPLORER 122 Terminal offers the following wireless interface:
•WLAN

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
Figure 2-5 Power Harness Wiring
•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
your terminal retailer for power/Ethernet cable or build your own cable assembly as shown
in section 6.
CAUTION: Use an Ethernet cable length no greater than 100m (328 ft.) to
ensure proper terminal operation.
