IDP-782 - Hardware Guide
The terminal’s built-in programmability allows it to work as a standalone data-messaging terminal, with
built-in I/O data collection and processing capabilities. Feature-rich software tools make programming easy
and shorten the design and testing time.
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, 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 terminal
l
Two-way communication for messaging to and from the asset for near real-time control
l
Up to 6,400 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 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.
The IDP-782 terminal can be configured to route cellular messages through the same SkyWave 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 SkyWave’s IsatData Pro Gateway supplies only
satellite messages. Refer to [
] for more information about configuring the terminal’s
cellular messaging transport.
