03 - NTRIP Modem Connection

The NTRIP Modem can be used with an RTK enabled VBOX or other GNSS receiver. 
 

The baud rate for the serial output of RTCM corrections from the Modem is 115200 kbit/s. You will need to make sure that the device you are using the modem with is configured to communicate at the same rate.

Connecting to a VBOX 3i ADAS

Antenna

Attach the supplied antenna (ANTMSTUBSMAM) to the SMA connector on the top of the unit.

SIM Card

The NTRIP Modem can either use the internal 4G modem via a Standard SIM card or a Wi-Fi connection to acquire the NTRIP correction messages from the server. If you want to use the internal 4G modem, you must use your own Standard data SIM card.

Insert the SIM card into the slot at the top of the unit. 

The logo on the SIM card must face the front of the modem and the end with the cut corner must be inserted first.

Note:

  • Make sure that the SIM card has been activated before you insert it into the modem. The easiest way to activate it is to put it into a USB 4G dongle and go through the steps to activate it on a computer before you insert it into the modem.

IMPORTANT
If the SIM card can be broken down into a Micro/Nano SIM, make sure that it is stable when you insert it into the modem as the Micro/Nano SIM could become detached from the card inside the modem.

Connection and Power

  1. Connect the Hirose end of the RLCAB170 to the Hirose connector at the bottom of the NTRIP modem.
  2. Connect the other end of the RLCAB170 cable to the DGPS port on the VBOX 3i ADAS.

    This cable provides power to the modem from the VBOX unit.
