The Orion is a radio modem with on-board telemetry inputs and outputs. It also contains
supervisory software which supports links and addressed networks. It is available in a
number of different versions to suit different applications, and has many user-programmable
features, which may be locally or remotely set.
Figure 3 shows the Orion in block diagram form.
Summary of notable features and options:
v Five modes to support different ways of working
v Four digital inputs, which may be used as pulse counters
v PTT facility to assist testing
v Four digital outputs
v Four analogue inputs (current loop or voltage)*
v Four analogue outputs (current loop or voltage)*, any one of which may be used
as an RSSI (signal strength) output
v Failsafe levels can be applied to outputs on system failure
v Alert output - pull-down to 0V or floating relay contacts option
v Two serial ports handling User Data, telemetry (I/O, SCADA) and AT
(configuration) commands
v Serial Port A can be soft-configured for RS232, RS422 or RS485; Serial Port
B is RS232.
v Sampling mode transmits any binary data format
v Unidirectional or half-duplex link, choice of error correction
v Choice of frequency band and power
v AT command set, local or remote programming of most features
v One-to-one or Base + Outstations configurations with addressing
v Outstations can be polled and/or volunteer data when thresholds are reached
(‘alarms’).
v Graphical User Interface (GUI) software supplied for configuration
*The four analogue ports can also be used to relay digital data if required,
depending on the application.
