INTRODUCTION TO THE ORION AND ITS USES
The Orion is a flexible unit designed to help you build point-to-point links and Base station-to-
multiple-Outstation networks, carrying serial user data, telemetry information, or both. In
simpler configurations, no additional equipment is required.
Each unit contains a modem and a transceiver, which can be ordered according to the
frequencies and range required.
The Orion’s particular feature is the provision of a small number of on-board analogue and
digital inputs and outputs in addition to serial data in/out. Where only serial data is required,
a model without these telemetry functions can be ordered.
Addressing allows one or more point-to-point links and networks to operate on the same
frequency, each Orion being able to handle both serial data communication and telemetry on
a time-sharing basis.
A repeater mode allows an Orion to relay data and telemetry messages for a group of units to
extend useful range.
In straightforward one-to-one (also known as back-to-back or mimic) and one-to-many
situations, the Orion can supervise polling, alarms etc. unaided. External control can be
added for more complex polling or SCADA (Supervisory, Control And Data Acquisition)
functions.
An Orion unit’s features and operating modes are user-programmable by using supplied
configuration software (a Graphical User Interface or GUI) running on a PC and covered in
Part Two of this manual; but it is also possible to configure the unit locally using AT
commands or remotely using special over-air commands, both listed in appendices in Part
Three of this manual.
