1892 1335 - Orion Radio Modem Operating Instructions - v2.9 / Aug 2009
29
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.
Modem Only version
The Orion is also available as a straight radio modem without the telemetry in/out capability.
Frequency band of operation
The Orion can be supplied to operate in the VHF, UHF and higher (e.g. 868MHz) bands. The
radio module in each Orion is built to operate over a certain range of frequencies (its
switching bandwidth ) under software control, for example 450-458MHz. Consult Sales at
Wood & Douglas for available frequency bands.
RF Power
The RF power can be chosen from very low powers up to 2W, depending on the radio
module.
Over-air data rate
The Orion can operate at up to 19,200 baud maximum over the radio link. If a lower data rate,
up to 9600 baud, is acceptable, a version which uses less radio spectrum (12.5kHz rather
than 25kHz) can be ordered. (Transmitters and receivers in all units must match.)
Alert output
The Alert output can be a pull-down (as for the digital outputs), or optionally floating relay
contacts, e.g. to signal power loss.
