GNSS Modbus Gateway
Modbus RTU slave providing precise date, time, position, altitude and speed data from GNSS receiver. Highly configurable.
The KTA-391 is a Modbus GNSS receiver. Extremely accurate time, position, altitude and velocity data is made available for any Modbus Master (PLC, RTU, SCADA system, etc) to interrogate.
The KTA-391 acts as a Modbus slave over RS-485. All data is available as Modbus holding registers. Two open collector outputs are provided; one gives a pulsed output to synchronise the clock with external equipment, the other indicates a reliable position fix. A status LED is also provided to show lock status. Modbus comms settings can be altered via RS-485 or USB. A PC application is provided as a free download for data analysis and troubleshooting.
The KTA-391 can also act as a Serial Gateway for the NEO-M8 GNSS receiver module. The receiver can then be accessed, evaluate and configured using Ublox's U-center software.
Magnetic mount active GNSS antenna (3m cable) is included.
