1.1 Overview of the Messaging System
SkyWave's IsatData Pro satellite messaging system is designed to support the
management of mobile or fixed assets located around the world. An asset fitted with one
of SkyWave's satellite based mobile terminals can have their status and locations
monitored, as well as send large messages.
The network provides the following key features and benefits:
Polling of terminal status and location
Scheduled reporting of terminal status and location
Transmission of text messages to and from a serial port on the terminal
Two-way communication for messaging to and from the asset for near real-time
control
Up to 6,400 bytes from-mobile messages
Up to 10,000 bytes to-mobile messages
Default acknowledged messages
Global service
Service is provided to end users by Solution Providers (SPs) who use the SkyWave
IsatData Pro network to offer particular applications and/or services to their clients. The
SPs link their application services to the satellite terminals by connecting to the IsatData
Pro gateway. This acts as the communications hub of the system, routing traffic to and
from the terminals and the various service providers.
Figure 2 IDP 700 Series System Architecture

IDP 700 Terminal Series - Hardware Guide
© SkyWave Proprietary 3 T206, Version 01
The IDP 700 series dual-mode terminal is based on the IDP 600 series Lua software and
supported by the same suite of IDP tools, enabling SPs a programmable platform they
can tailor to their specific applications.
1.2 Terminal
3
Terminals operate on the IsatData Pro network at an elevation angle of 20° to 90°. The
terminals are self-contained, compact, and provide low power consumption.
The terminal's built-in programmability allows it to work as a stand-alone terminal with
built-in I/O data collection and processing capabilities. Terminals are suitable for the
AVL market.
Feature-rich software tools make application design easy, and shorten the design and
testing time. SkyWave also provides consulting services to SPs to help program the
terminals and get customer applications running quickly.
The terminals include an IsatData Pro satellite modem, a cellular modem with two SIM
card slots, and programmable microprocessor and file system for firmware and
peripherals. Peripherals include CAN bus for vehicle bus access, several I/O
(input/output) feeds, RS-485, and two RS-232 ports.
Figure 3 IDP 700 Series Transceiver
1.3 Terminal Key Features and Benefits
CAUTION Do not rely solely on the terminal for
emergency (SOS) calls.
The IDP 700 series terminals have the following key features and benefits:
Designed to be used as a standalone or incorporated into an SP solution
Built-in GPS receiver to calculate position, speed and heading
Quick and easy installation reduces labor time and costs
Ships with installed firmware
Flexible custom application design (Lua Services Framework)
Broad operational temperature range
Satellite plus cellular modem integration

Discrete I/O ports to interface with a wide range of after-market accessories
Rugged construction
Dual SIM
1.4 Terminal Components
Each terminal consists of the following components, excluding interconnecting cabling.
Transceiver unit
GPRS antenna
IsatData Pro remote satellite antenna
Cable shroud (optional)
1.4.1 Transceiver Unit
Each terminal is a self-contained unit, including satellite transceiver (modem), quad-band
GPRS modem, GPS module, programmable microcontroller, and multiple I/O
(input/output) feeds capable of monitoring and controlling external sensors and devices.
Ideal for mobile applications, it is also suitable for fixed installations.
The transceiver unit (Figure 4) is not waterproof. Use it in an indoor environment, e.g.,
inside a vehicle, away from environmental exposure (i.e., any form of moisture such as
rain, snow, or pooled water). The transceiver is a side connector mounting unit.
Figure 4 Transceiver Unit
Arranging the transceiver unit’s connectors (Figure 5) at one end of the unit makes
installation easier. Sturdy flanges on the side make mounting quick and easy.
Figure 5 Connector Positioning
A screw-on doorway on the side of the unit (Figure 6) provides easy access to the two
SIM card holders for installation and replacement.

1.4.2 Cable Shroud
The optional cable shroud protects the cable connectors that connect to the transceiver
unit. The cable shroud has three (3) pass through features for the following cables:
RF cables (sides)
I/O cables (center)
Figure 7 Cable Shroud
1.4.3 IsatData Pro Remote Satellite Antenna
The IsatData Pro satellite antenna is waterproof (IP67 rated) and designed to operate in
extreme environments. It has four mounting flanges for installation.
Each satellite antenna connects to the transceiver unit using LMR195-PVC (or
equivalent) coax cable terminated with a curry yellow colored FAKRA RF connector.
CAUTION Observe proper ESD handling procedures
when handling the remote antenna
cable connector.
1.4.3.1 Satellite Antenna Assembly
The satellite antenna assembly is an active antenna –it uses a DC voltage on the coax
cable. The DC voltage powers an LNA for the satellite receiver and a power amplifier for
the satellite transmitter.

The antenna assembly consists of a single RoHS compliant PCB, and assembly
containing no user serviceable parts. The antenna assembly consists of a single RoHS
compliant PCB protected by an IP67 rated waterproof enclosure.
The IDP-780 flex uses the standard satellite antenna (Figure 8) while the IDP-790 flex
uses the low elevation satellite antenna (Figure 9).
Figure 8 Standard Satellite Antenna
Figure 9 Low Elevation Satellite Antenna
1.4.4 GPRS Antenna
Terminals use a standard low-profile GPRS antenna. The GPRS antenna is a quad-band
adhesive patch antenna, designed for installation on the interior of a vehicle windshield.
It connects to the transceiver unit with a 2.5 m RG174 coaxial cable terminated with a
FAKRA connector.

In its processing mode the Lua services are actively running.
Power Off Mode
In this mode the application processor and modem are both
powered off. All terminal peripherals are off as well.
1.5.2 Satellite Modem
For the most part, the satellite modem operates independently from the application
controller. Consequently, power consumed by the satellite modem must be added
separately to determine a terminal's overall power consumption.
Table 2 Satellite Modem Operating Modes
Operating Mode
Description
Transmit Mode
In transmit mode the modem is transmitting a signal to the gateway.
Receive Mode
In receive mode the modem is attempting or actively listening to the
satellite (listening on the bulletin board channel or on a traffic
channel).
Sleep Mode
This is the time between wake-up intervals. When a terminal is
going to sleep, it stops receiving messages for a wake-up period.
Both the terminal and gateway track the wake-up interval.
Consequently, when a terminal is in sleep it does not miss
messages.
1.5.3 GPS
GPS is a modem peripheral that is either on or off.
