INTRODUCTION
1. INTRODUCTION
1.1 About this User’s Manual
This User’s Manual includes the informations necessary for the installation and operation of the GPS module. This
document describes external interfaces and how to configure this module with eZ Software.
Read this document completely before using this module.
1.2 General information
The GPS module is designed to acquire L1-C/A GNSS signal and to output a complete PVT (Position, Velocity, Time)
through synchronous and asynchronous parameters available for standard outputs (PCM, recorder, Ethernet …).
The GPS module provides system synchronization capabilities.
1.3 Reference Documents
1.4 Safety
Observing the safety instructions will help prevent personal injury or damage to the device. Therefore, carefully
read through and adhere to safety instructions before using this equipment. It is also absolutely essential to
observe the additional safety instructions on personal safety that appear in first chapter of [RD1].
1.5 Installation, transportation, storage
For unpacking, inspection and installation of the GPS module, refer to the related chapter of [RD1].

OPERATION
3. OPERATION
3.1 Introduction
This section provides all the information necessary to configure, monitor and control the GPS for operation using
eZ software. This chapter assumes DAU stack is correctly assembled and connected (Refer to RD1, RD2). eZ
software must be running, and the internal structure of the DAU must be defined in the System Inventory activity
(Refer to RD3).
3.2 System Inventory
▶Select System Inventory activity.
▶In the Devices tab, select the GPS module in the DAU (e.g. XMA-1). The GPS module configuration menu
appears on the right side.

Functional set ◆iTalk
◆NMEA
◆Enables GPS receiver to communicate with an external host
such as PC. It is a low level communication layer that allows
host to control the receiver and retrieve data from it.
◆The receiver produces and interprets messages in accord-
ance with NMEA 0183 V3.0 standard. It is possible to send
commands to drive the GPS receiver chipset and extract nav-
igation data. See NMEA chapter for more details.
Data source ◆Internal (Chipset GPS)
◆External (RS232 exter-
nal interface)
◆The data received by the internal GPS chipset are used.
The RS232 area is greyed and these parameters unmodifia-
ble.
◆External communication system must be connected to the
external interface . When External is selected, the RS232 area
becomes modifiable. Enter the serial link parameters to be
compatible with your own communication system.
