INTRODUCTION

Sutron’s Xpert family of DCPs (both the 9210/B and the Xpert/2) have been designed to be
easily expandable by adding additional software libraries, called Sutron Link Libraries (SLLs).
One such library is Iridium.sll, which adds the ability for the Xpert to communicate over the
Iridium network using Short Burst Data (SBD) messages. This document is the user manual for
Iridium.sll. The following topics are discussed:

•

How to install the library

•

What features are supported by the library

•

How to configure the Xpert for Iridium communications
