ORION On-Board Telemetry Radio Modem

ORION On-Board Telemetry Radio Modem

Half-duplex, 19,200bps over-air, data rate. RS232/RS422/RS485 interface. Synthesised VHF and UHF options.


TX power options up to 5 watts. Store and forward repeater feature. 4 Digital Inputs and Outputs. 4 Analogue Inputs and Outputs. Over-air reconfiguration and output setting. This is the ORION On-board telemetry radio modem. The ORION has a selectable RS232, RS422, RS485 user interface for serial data messaging allowing easy connection to Remote Telemetry Units, Pan Tilt Zoom camera controllers etc. Over-air data rate is 19,200bps when a 25kHz bandwidth radio module is fitted (9600bps in a 12.5kHz channel). ORION's frequency range is from 100-868 MHz depending on which RF module is used.

Remote control

The four digital inputs allow monitoring of on/off type signals such as PIR alarms, door contacts, control buttons etc. The four analogue inputs allow monitoring of 4 to 20mA current loops and 0 to 10volts measurements. Examples are water levels, wind speed etc. The Digital and Analogue outputs can be set to specified levels remotely over-air using another ORION giving a complete ‘remote control’ solution. The I/O signaling slots seamlessly into any serial data being sent or received by the ORION. In addition to its four analogue inputs, the ORION monitors and signals its supply voltage. This function allows for long-term battery operation with early notification of battery performance drop.

Master-Slave telemetry

The ORION can be built in various versions which use the SXn50 series, the G-MAX or the T series radios. With the supplied GUI, a very capable, fully configurable, Master - Slave telemetry system is possible.

As a repeater

Using Store and Forward techniques, an intermediate ORION can act as a repeater thus greatly extending system operational range.

Custom version

The option exists to specify a version of the ORION without the telemetry I/O functions where only a radio-modem is required.
