QDR 900MHz Digital Radio

The QTech Digital Radio (QDR) is a low power digital modulation radio solution which is fully compliant for use in Australia and New Zealand.

QDRs provide low cost RS485 or RS232 cable replacement options and are ideal for use between DATRAN RTUs and expansion modules, or between industrial controllers and sensors.

September 2024 – The QDR is available again.

The design team reengineered the QDR to overcome the previous component sourcing issues. Please contact us for availability.

Application examples include RS232 master/slave configuration, as a “Point to Point” system or even as a “repeater” for more challenging projects within certain packet size limitations (see the datasheet for more information).
