6.5. Original Equipment Manufacturer (OEM) CDPD Devices
The SB300 Type III-size CDPD modem is a cost-effective wireless data modem that can be
integrated into original equipment manufacturer (OEM) devices. The more fully-featured SB320
also offers circuit-switched cellular (CSC) support and wireline connections for data and voice.
6.6. End-to-End and Legacy Systems
The Sierra Wireless AirPac system provides wireless connectivity and protocol conversion for
transaction-based applications based around legacy systems. These include Automated Teller
Machines (ATMs), Point-of-Sale (POS) devices, remote terminals for travel reservations, and
lottery ticket dispensers. Such systems often run on legacy protocols, such as SDLC and X.25, for
which AirPac provides data conversion to operate over the CDPD network.
6.7. Software
Sierra Wireless also creates software to support its hardware. That software includes:
• Watcher, which is a graphical, menu-driven application for operating and configuring Sierra
Wireless modems.
• WirelessExpert, a wizard-driven setup utility that makes installing Watcher and configuring
Sierra Wireless modems even simpler.
• PortWatcher, a tool to configure, monitor, and control the general-purpose I/O ports of the
MP200 series of CDPD modems.
• SkyWatcher II, software to configure and monitor the GPS module installed in some Sierra
Wireless products.
• Toolkit, a graphical, menu-driven application for configuring Sierra Wireless modems.
• CDPD Software Development Kit (SDK), an aid to developing applications that use Sierra
Wireless CDPD products. For more information visit www.sierrawireless.com/developers/
