Screen Overview
More detailed information on the front screen can be found here.
Setup
When you use the NTRIP Modem for the first time, it becomes a Wi-Fi access point. You can then configure the settings
by logging into this access point using your phone or a computer. A webpage is then used to configure the unit to use
the internal GSM modem or an external Wi-Fi hotspot to connect to your chosen correction service. Settings are
retained after a power cycle.
If the unit is configured to use both the internal GSM modem and an external Wi-Fi hotspot, it will attempt to auto
connect to the Wi-Fi hotspot first on power up.
1. Attach the supplied antenna to the SMA connector on the top of the unit.

unit, with the logo facing the front screen side/ contact facing the rear, chamfered edge in first.
Note: Ensure the card has been activated.
3. Connect the supplied RLCAB170 cable from the bottom Hirose connector on the unit to the 'CAN' port of the
VBOX 3i or other GNSS receiver. If using VBOX 3i, ensure that the correct DGPS mode has been enabled, more
information on this is available here.
4. Apply power to the connected VBOX or other GNSS receiver. If you are using another GNSS receiver and power
isn't available via the Hirose connection, the modem can be powered from the USB socket using the
supplied TTV2AMBBLK1M cable. More information on this is available here.
