GNSS2 / InstallingTheGNSS2

Installing the GNSS2

Quick Checklist

  • Attach the supplied GNSS antenna to “GPS” on the rear of the unit.
  • If using 4G LTE corrections, insert a SIM card
  • Attach a 4G LTE antenna to “4G Main” on the GNSS2 (whether using corrections over 4G LTE or not)
  • If using Base station corrections, attach a radio modem configured at 38400 baud to RS232 port 2 via a breakout cable on the GNSS2.
  • Supply 12V power to the GNSS2.
  • Configure the GNSS2 for relevant outputs (NMEA / RT format serial), CAN messages
  • Connect the RS232 port 1 or CAN outputs as required

Full Instructions

The GNSS2 will be supplied with a suitable dual frequency GNSS (GPS + GLONASS) antenna; this must be connected to “GPS In” on the rear of the unit. If the GPS2 is to receive 4G LTE corrections, then a SIM card must be inserted into the rear of the GNSS2, and a 4G LTE GSM antenna must be attached to “4G Main” on the rear of the GNSS2.

NOTE: A 4G LTE antenna should always be attached to the GNSS2 wherever the corrections are coming from.

If the GNSS2 is to receive base station corrections, then attach the supplied radio modem to the “Modem” port on the rear of the GPS2. If using a third party radio modem, ensure that its serial output is configured to run at 38400 baud. Also ensure that the attached base station is set to output RTCM 3.x corrections

If using Race Technology format RS232 data, or NMEA data, attach a null modem cable directly to the serial port on the rear, or via the attached breakout cable to serial port 1.

To receive CAN data, attach a CAN cable to “CAN” on the rear of the GNSS2. The cable must contain termination if required, since the GNSS2 does not contain internal termination.

Connect 12V power to the rear of the unit using the supplied cable.

Configure the GPS2 through the USB port.

Check for correct operation on the LCD.

If connecting to a Race Technology data logger such as the DL2, ensure that the logger is configured to receive the relevant GPS messages on whichever serial port the GNSS2 is attached to.
