Page 5: Introduction To The Orion And Its Uses
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. - Page 6 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.

Page 9: Orion Modes
ORION MODES The Orion supports five modes of operation to enable you to build exactly the link or network you want. They are: U - User Data only R - repeater I - independent (standalone) telemetry + User Data E - externally-controlled telemetry + User Data L - data logging Depending on the mode you select, other features become available. -
Page 10: Mode U - Data Only
Mode U - Data Only The Orion can be used as a high-performance data modem without using its built-in telemetry capabilities, and can be ordered without telemetry hardware at a saving in cost. Mode U supports half-duplex or simplex serial User Data communication via Serial Port A. Typically, two modems will communicate half-duplex, but other topologies are possible: Using the address facilities of the Orion, many such pairs may share a frequency (on a time-sharing basis). - Page 11 One unit polls the other, volunteering its inputs, and the other replies with its inputs. Each then mimics the other’s inputs on its outputs. In either of these arrangements, alarms are sent spontaneously under predefined conditions unless suppressed, and are acknowledged by the other unit. See page 16. It is also possible to run a one-to-all topology in this mode, where the Base unit broadcasts its inputs regularly, and all other units duplicate them on their outputs.
-
Page 12: Mode E - Externally-Controlled Telemetry
Mode E - Externally-controlled Telemetry This mode is used where the inputs and outputs at many Outstations are individually interrogated and controlled by external SCADA equipment at a Base station. The Base unit relinquishes most of its functions to the SCADA equipment, which controls polling, input/output, acknowledgements, retries and alarm handling via Serial Port B. -
Page 13: Mode L - Data Logging
Mode L - Data Logging Logging mode is used where equipment at many sites produces information, and there is a need to retrieve it periodically from a central location. At each site, an Orion Outstation stores serial data presented to Serial Port A, and relays it to the Base when it is polled. The Base polls addresses between one and the total number of sites, receiving the data and outputting it on Serial Port A which is connected to external logging equipment. -
Page 14: Addressing
ADDRESSING In order that you can create systems containing two or more Orions, or even several separate systems, all on the same frequency, the Orion supports addressing. This works by having one or more groups each containing between two and 254 Orion units. Each Orion bears the number of a group to which it belongs, and its own unique number within that group. - Page 15 Group 0 messages are treated as broadcast, and are not acknowledged or replied to. Therefore they must not be used when Packet over-air protocol is used. Repeaters ignore messages with GroupID 0. GroupID 255 is reserved for future use, and is not a permitted value at present. Identities can be set with the following commands (see p.63 for detailed information): GroupID UnitID...
-
Page 16: Alarms And Alerts
ALARMS AND ALERTS Alarms and Alerts only apply where there are telemetry inputs and outputs, and therefore only to Modes I and E. An alarm is a state where an input has fulfilled a specified condition in terms of magnitude, logic state, time etc. -
Page 17: Failsafe Feature
Alarm Parameters Raise conditions Clear conditions Comms Poll period time Ack is not received to n (0=off) (ATS183) polls (Base) or poll is not and tolerable received within poll time Next poll is received number n of + 3s for n consecutive missing periods (Outstation) messages... - Page 18 Before going into failsafe mode, the unit transmits a message announcing that it will go into this mode unless a poll is received within a programmable time. If the poll is received, it responds in the usual way and goes back to normal operation. Otherwise it goes into failsafe mode.
-
Page 19: Serial Interface Configuration
SERIAL INTERFACE CONFIGURATION The Orion has no user-selectable switches or links, but is fully programmable via its serial data ports, using either the supplied Graphical User Interface described in Part Two of this manual, or the AT commands listed in Part Three. The serial ports are the same ones used during operation for User Data, SCADA and I/O. -
Page 20: Telemetry Configuration
TELEMETRY CONFIGURATION There are three basic telemetry modes, MI, ME and ML, with variations as explained on pages 10 to 13. This section looks at the parameters which are common to several modes, and the parameters which are mode-dependent. Common Parameters (MI and ME) Analogue input scaling (four inputs, 0-2.5V, 0-5V, 0-10V, 0-20mA* (ATS300n) - Page 21 (ATS170) Unit ID The Base unit is defined by having UnitID set to 0, and is responsible for polling if applicable. For one-to-one configurations, set the single Outstation to UnitID = 1. Although Outstations in a one-to-all configuration are always addressed together using a broadcast code, they should be given separate Unit IDs from 1 up to 254 so that they can be separately addressed for maintenance or distinguished for User Data purposes.
-
Page 22: Mode E Parameters
Mode E Parameters (ATS170) Unit ID The Base must have the UnitID 0 and is connected to the SCADA. The SCADA must insert UnitID 0 as the source in its messages so that replies are correctly routed on return. Outstations should be given Unit IDs from 1 up to 254, although they need not be contiguous. -
Page 23: Mode L Parameters
Mode L Parameters (ATS170) Unit ID The Base is defined by being given the UnitID 0. Outstations should be given Unit IDs from 1 up to the number of Outstations, maximum 254, and must be contiguously numbered. Dest ID During normal polling, this setting is ignored: the destination is (Destination for dynamically controlled by the Base, and Outstation replies always go messages which... -
Page 24: User Data Configuration
USER DATA CONFIGURATION Some User Data configuration may be relevant in Modes I and E as well as U, because User Data may be carried beside telemetry in those modes. Mode U Parameters Unit ID The address of the unit. Since there is no distinction between Base and (ATS170) Outstation for Data Only, UnitID may be any value from 0 to 254 provided it is a unique address within the Group. - Page 25 buffer is empty, which may either be because there is no more data, or, in the case of a slow source, because transmission has outstripped the input. If a further byte appears in the buffer, the process is repeated. When set to End of Message, the transmission sequence is triggered by a break in the User Data input.
-
Page 26: Repeater Configuration
REPEATER CONFIGURATION A repeater serves a single group, relaying User Data or telemetry messages which it receives without alteration of any kind. The group must use addressing (i.e. not GroupID 0). It prevents proliferation of messages by maintaining a list of messages already relayed, which it ignores. Broadcast messages with the DestID 255 are relayed, but messages with a GroupID of 0 are ignored. -
Page 27: Radio Configuration
RADIO CONFIGURATION A number of different radio modules may be fitted to the Orion for different bands, powers etc. As part of the test and setup routine at the factory, most of the radio parameters will be set up to suit the module fitted, although you can alter them if necessary with reference to Part Two of this manual or the AT Command Reference starting on page 63. -
Page 28: Protocol Selection
Protocol Selection is a basic half-duplex link for asynchronous serial data. It has no error correction. TU also provides a half-duplex asynchronous serial data link, but it has Feed-forward Error Correction (FEC) so that many errors can be corrected. provides a half-duplex asynchronous serial data packet link with both FEC and requests for repeat transmission of corrupt packets to provide an error-free link. -
Page 29: Options When Ordering
OPTIONS WHEN ORDERING Many options are user-programmable, but the options below must be specified when ordering so that the correct version of the Orion can be supplied: OEM PCB version The Orion is available uncased as a PCB for mounting in OEM equipment.

Page 41: Introduction To The Graphical User Interface (Gui)
INTRODUCTION TO THE GRAPHICAL USER INTERFACE (GUI) The Orion GUI is a program which runs on a PC under Windows, and provides a simple and convenient way to set up local or remote units. It is connected to Serial Port B of the local or Base unit, and offers tools to manage (save, retrieve etc.) as well as to edit configurations. -
Page 42: Connecting The Gui To An Orion
CONNECTING THE GUI TO AN ORION Ensure that the serial comms port of the PC which is used to run the GUI program is connected to the Orion Serial B port using a suitable cable as described on page 33. If your computer has no serial port, you need to use your computer’s USB port and a serial-to-USB adaptor: see Appendix D on page 85, 86. - Page 43 Click on the COM port listed at the top left-hand corner to which you have connected the Orion, e.g. COM1. This should establish contact with the Orion, and the window appearance should change, with the message Modem Connected displayed. The unit’s details are uploaded to the GUI and some are displayed.

Page 46: Serial Interface Parameters
SERIAL INTERFACE PARAMETERS To change the parameters for either port of the Orion, select the values you want on the Serial Interface tab. Serial Port A can be set to many protocols, and is used for User Data. Serial Port B has relatively fixed protocols, and is used for configuration and telemetry (SCADA). -
Page 47: Addressing
Addressing Section Addressing on page 14 explains the addressing scheme used by the Orion in detail. If you intend to use no addressing at all, select the No Addressing checkbox and ignore the other addressing details. This is only available in Mode U. Remember that repeaters cannot be used in such a network. -
Page 48: Polling
Polling Poll timer unit is multiplied by the Poll timer time to allow times from 100ms to 182 hours (over a week). In Mode I, leaving this at zero enables Spontaneous Mode, which is not polled. Entering a time makes the Base poll with that frequency, and the Outstation expect a poll and raise an alarm if it is not received with that frequency. -

Page 63: Appendix A: At Command Reference
APPENDIX A: AT COMMAND REFERENCE Normally the GUI is the best way to configure, control and interrogate a local Orion unit. However, if you want to use your own equipment and software to do this, you can use either of the serial ports to send ASCII AT commands and receive replies, which are listed in this Appendix. -
Page 64: Command Syntax
If any of these conditions is not fulfilled, then the string "+++" will be transmitted as normal data. Note that one or more consecutive “+” characters in the input data may be held in the unit until it is determined that it is not a Command Mode instruction. Command Syntax Once in Command Mode, commands are issued by sending codes consisting of ASCII characters. -
Page 65: Ending Command Mode (Ato)
Leading zeros and the plus sign for positive values may be entered or omitted. Thus these strings are considered valid entries for a parameter shown as xxx: +001 whereas 0001 is not (too many places). Where a number of places are shown after a decimal point, the decimal point must be entered, but no leading zero is required before the point, and not all the trailing spaces need be filled. -

- Page 91 Notes: This adaptor converts all four digital outputs to floating SPDT relay contacts. The Alert output is a relay or open-collector output, depending on how the unit was ordered, and is not converted. If the Alert output is to be used, and is an open collector output, the 0V return is via PL1. If LED indication is required when an output is in its energised state, 12V at up to 40mA must be provided via connector PL1, which may be taken from the same supply as the Orion.
