Overview

QU232M is an external GPS receiver, the protocol is NMEA 0183, the default baud rate is 4800. Supports GPS/WAAS+QZSS+SBAS, supports up to 66 satellite tracking channels, and with satellite-based enhanced satellites, the horizontal positioning accuracy can reach 2 meters.
QU232M also supports SBAS (Satellite-Based Augmentation System) which is the generic name given to the differential signal transmitted by various local geo-stationary satellites. SBAS allows GPS receiver to remove errors in the position due to environmental conditions and improves accuracy down to <2m. Using WAAS in the US and EGNOS in Europe the QU232M will automatically switch to differential SBAS mode when available.
This product is compatible with Garmin, raymrine and other GPS sensors. Please make sure your device has an NMEA 0183 interface and operates at 4800 baud before purchasing.

Factory configuration:

Please note that do not connect the GPS signal wires (TX RX) to the positive pole of your power supply, otherwise it will immediately damage the antenna.
If you don't know how to connect wires, please provide the NMEA 0183 interface description of your device to customer service and request assistance.
