1 Product Overview
Each IDP-280 (Figure 1) and IDP-290 (Figure 2) IsatData Pro satellite modem consists of
a single environmentally sealed mechanical enclosure containing an integral antenna, a
satellite modem for communicating with the satellite, an integral GPS subsystem, two
digital outputs, and an RS-232 port.
The IDP-280 has a standard satellite antenna and operates at an elevation angle of 20° to
90°, while the IDP-290 has a low elevation satellite antenna and operates at an elevation
angle of -15° to 90°. The IDP-290 is also available as an OEM model. Refer to
APPENDIX A for further details.
Figure 1 IDP-280
Figure 2 IDP-290
Each modem is designed for industrial and fixed applications or to be mounted outdoors
on a wide range of platforms such as vehicles or boats.

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 equipped with
an IDP modem can have its status and location monitored, and send large messages.
The network provides the following key features and benefits:
Polling of unit status and location
Scheduled reporting of unit status and location
Transmission of text messages to and from a serial port on the unit
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
Broadcast messages
Default acknowledged messages
Global service
Figure 3 SkyWave's IsatData Pro Network
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 units by connecting to the IsatData Pro
gateway. This acts as the communications hub of the system, routing traffic to and from
the modems and the various service providers.
Configuration and data retrieval from the unit can be easily accomplished through
Internet-based application services provided by SPs or by integrating existing customer
enterprise software to receive information from the Gateway.

1.2 Features and Benefits
The modems operate on the IsatData Pro network. The units are self-contained,
environmentally sealed, compact, and provide low power consumption.
The units include an omni-directional antenna, satellite modem, GPS, and two digital
output feeds.
Part numbers are specified in Table 16.
Refer to APPENDIX A for IDP-290 OEM details.
The modems are available in two configurations: bottom connector or side connector (see
figures below).

CAUTION Do not rely solely on the
modems for emergency (SOS) calls.
The modems have the following key features and benefits:
Designed to be incorporated into an SP solution
Built-in GPS/GLONASS receiver to calculate position, speed and heading
Quick and easy installation reduces labor time and costs
Ship with installed firmware
Wide operational temperature range
Rugged construction

1.3 Operating Modes
The modem operates in the modes described in Table 1.
Table 1 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 power saving mode when the modem turns its main
power off between wake-up intervals. Both the modem and gateway
track the wake-up interval. Consequently, when a modem is in sleep
mode it does not miss incoming messages. If a modem has a
message to send, it automatically exits sleep mode without waiting
for the next wake-up interval.
Idle Mode
In this mode the modem is awake, but neither receiving nor
transmitting.
1.3.1 Peripherals
These peripherals are either on or off. Power consumption is affected when they are
powered on.
Table 2 Peripherals
Operating Mode
Description
GPS/GLONASS
Can be powered on independently of the IsatData Pro receiver.
RS-232
The RS-232 transmit driver is enabled whenever a valid input
RS-232 signal is detected.

3.2.3 Immunity to Power Supply Failure
The modem meets all specifications and does not display any corrupted software or loss
of essential data after being subjected to three 60 s power supply failures per IEC 60945,
section 10.8.
3.2.4 Fast Transient Immunity
The IDP-290 operates normally after being exposed to fast transients per IEC 60945,
section 10.5.
3.2.5 Load Dump Circuitry
The modem's power supply input voltage range is 9 to 32 V. Above this range the load
dump protection circuitry disconnects external power so that the modem is not damaged,
up to 150 V. When the input voltage drops below the threshold, the modem recovers,
going through power on reset.
With this protection, the modem is capable of withstanding load dumps as specified in
SAE J1455 (rev Jun 2006) paragraph 4.13.2.2.1.
3.2.6 Fuse
The modem has an internal 5 A fuse that provides protection in the event of an internal
short on the modem. The internal fuse cannot be reset and is not field repairable.
3.2.7 Inrush Current
Inrush current transients occur when the modem is:
First powered on.
Preparing for transmit. This is when the modem switches its internal voltage rail
to a higher voltage for transmitting.
Modem starts to transmit. This is when the modem's power amplifier is turned
on.
