Data-logging controllers for plant, marine and remote sites.

North Quay Systems designs and builds the NQ series of industrial controllers: rugged units that collect sensor data, buffer it locally and forward it over any available link. Firmware, configuration tools and documentation are available in the Downloads section.

NQ-200

Eight analogue and sixteen digital inputs, 4 GB local buffer, Ethernet and RS-485. The workhorse of the range.

NQ-350

Adds cellular and satellite uplinks, redundant power and an extended temperature range for unattended sites.

NQ Config Tool

Desktop application for Windows and Linux: device setup, channel calibration, firmware updates and log export.

Firmware 2.4.1 for the NQ-200/350 is available. It fixes buffer flushing on intermittent links and adds Modbus TCP write support. See Downloads.
