ST 9100 - HARDWARE GUIDE
Figure 1: ST 9100 Satellite-Cellular Transceiver
The transceiver’s built-in programmability allows it to work as a standalone data-messaging transceiver, with built-in
I/O data collection and processing capabilities. Feature-rich software tools make programming easy and shorten the
design and testing time. The transceiver can also be configured with terminal apps. Terminal apps are configurable
device-level applications that include specific feature sets that are implemented by ORBCOMM. Contact Customer
Support or your Account Manager for further details.
1.1 Overview of the Messaging System
The 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 ORBCOMM's satellite based mobile terminals can have their
status and locations monitored and send large messages.
The network provides the following key features and benefits:
l Polling of terminal status and location
l Scheduled reporting of terminal status and location
l Transmission of text messages to and from a serial port on the transceiver
l Two-way communication for messaging to and from the asset for near real-time control
l Up to 6,399 bytes from-mobile messages
l Up to 10,000 bytes to-mobile messages
l Default acknowledged messages
l Global service
Service is provided to end users by Solution Providers (SPs) who use the 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.
The terminal can be configured to route cellular messages through the same IsatData Pro Gateway that supplies
satellite messages. This is shown as Option 1 in the System Diagram. Option 2 represents a terminal configured to
route cellular messages directly to a customer or Solution Provider proprietary cell server. In this case the connection
to ORBCOMM’s IsatData Pro Gateway supplies satellite messages. Refer to [T404, N206, and N210] for more
information about configuring the terminal’s cellular messaging transport.
