Description:

The KTA-291 is a Modbus GPS receiver. Extremely accurate time, position, and velocity data is made available for any Modbus Master (PLC, RTU, SCADA system, etc) to interrogate.

Magnetic mount active antenna included (GPS-020).

Data Available:

  • UTC Date
  • Time accurate to 60 nanoseconds
  • Latitude and Longitude accurate to 2.5 metres
  • Altitude
  • Velocity
  • Course over ground (direction)
  • Number of satellites in use
  • Accuracy of returned data

Typical Applications:

  • Provide accurate timestamps to a SCADA system for logging
  • Synchronise logging operations across timezones
  • Location mapping and geotagging
  • Altitude readouts for weather observations
  • Precise speed readouts for vehicular sports/activities
  • Direction data for orienteering or navigation

The gateway 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 GPS position fix. A status LED is also provided to show GPS lock. Modbus comms settings can be altered via RS-485. A PC application is provided as a free download for this purpose. Shorting the reset terminal to ground returns the comms to default.

Note: the lower label on the sticker depicts the "closer" terminal. For example, V+ is the terminal closer to the sticker, GND is the neighboring terminal further behind.
