MSAT-G2 Installation Guide
Introduction
The purpose of this guide is to provide assistance to personnel installing the new MSAT-G2
mobile satellite radio equipment. The guide starts off by providing installation-specific
information on each component of the radio. Installation tips are then offered for fixed-site
and vehicular scenarios. A section on commissioning instructions follows. The guide concludes
with a troubleshooting section.
Installation Warning
This product is to be installed by Authorized Service Personnel. Damages resulting in the
failure to conform to the instructions found herein, as well as standard installation practices,
will be the responsibility of the installer.
MSAT-G2 Mobile Satellite Radio
The MSAT-G2 mobile satellite radio is comprised of three core component parts: the
transceiver unit (the small black box), the antenna system (white domes) and the handset.

Transceiver Unit (TU)
The TU provides the interface for the handset and antenna unit (AU) and manages the
communications over the MSV network. It also distributes power to the handset and
Antenna Unit (AU).

The TU is equipped with the following ports:
Power Port
The power port is the connection from the power supply (vehicle battery or some other 12
VDC power source) to the TU. The power cable has a +12V power line, a +12V ignition
sense line, a horn alert line and a ground line.

Ethernet and Serial Ports
RJ 45 Ethernet Port
The RJ 45 Ethernet port is available for upgrade and future expansion of functionality.
The port supplies standard Ethernet line levels and supports all defined control line signaling.
The pinout of the port supports a direct straight-through connection to a PC with a standard
Ethernet cable. The PC shall be supplied with a dynamic local IP address using a standard
DHCP exchange.

Serial Port
The serial port is a female DB-9F RS 232 and can be used for NMEA output (GPS) and
crossbanding.

Figure 6 – Serial Port Pinout
Antenna Port
The antenna port is a 50 Ohm female TNC. This line carries RF, signaling, and DC power for
the antenna. Note: Grounding the center conductor while power is applied to the transceiver
can cause the transceiver's fuse and/or a fuse in the vehicle to blow. No modifications should
be made to the RF cable under any circumstance

Handset Port
The RJ45 handset port is used to connect the handset to the TU. The connector type is
a modular 8 position and 8 conductor RJ45. The pinout is as follows
Pin Number Signal Name
1 Audio TX + Microphone
2 Audio TX – Microphone
3 Data TX – TU Send
4 Data RX – TU Receive
5 + 12 VDC

System Power Requirements
There is only one power connection for the entire radio. This must be connected to a
12 VDC power supply.
Power requirements and consumption are as follows:
Voltage Input Minimum 11.5 V DC
Voltage Input Maximum 15.6 V DC
Total Current for AU,TU & Handset (Max.) 3A
Required Fuse 5A
