NovAtel Application Note
1 Overview
This application note describes how to communicate with the OEM628 receiver by sending
commands and obtaining logs through Ethernet interface and gives the step-by-step process for
connecting the OEM628 through the Ethernet interface using NovAtel CDU or terminal, setting
up a base/rover configuration through Ethernet connectivity, and utilizing the NTRIP interface.
PC/laptop Ethernet port connections are also described for both Windows XP (with SP3) and
Windows7 operating systems.
2 Required Hardware
The following hardware is required to setup an Ethernet interface to an OEM628 unit:
• user supplied PC/laptop with an available Ethernet, serial and/or USB port
• OEM628 with an OEM628 Dev Kit, power cable and serial communication cables
• one (1) RS-232 null modem cable
• two (2) CAT5 Ethernet cables
• optional USB-to-serial adaptor
• user supplied Ethernet network, hub or wired router
• one (1) or two (2) GNSS antenna – GPS 702-GGL antennas
• one (2) or two (2) standard 5 meter 50 ohm TNC-to-TNC antenna cable

3 Static IP Address Configuration
For this configuration, unique IP addresses are assigned to both OEM628 and PC. TCP/IP will be
used to for the connection in this simple network. This configuration can be used in a bench test
environment to confirm Ethernet functionality. Connect the OEM628 as shown in the diagram
below.
Figure 1: Cross-Over RJ45 Ethernet Cable Configuration
Note: The following static IP addresses will be assigned to the OEM628 to illustrate the setup:
IP address = 192.168.74.10
Subnet mask = 255.255.255.0
Gateway = 192.168.74.1
1. Connect to your OEM628 through a cross-over serial cable or a USB port with either
NovAtel CDU or another terminal program such as Windows HyperTerminal. For more
information on receiver communication, please refer to our online video tutorial
Communicating with the Receiver found at http://www.novatel.com/support/knowledge-
and-learning/video-tutorials-and-tech-presentations/.
2. Send the following commands:
ETHCONFIG ETHA AUTO AUTO AUTO AUTO
ICOMCONFIG ICOM1 TCP :2000
IPCONFIG ETHA STATIC 192.168.74.10 255.255.255.0
192.168.74.1

NovAtel Application Note
Note: The receiver will echo with an <OK acknowledgement for each command
entered.
To confirm the TCP/IP configuration, issue the following command:
LOG IPCONFIG ONCE
To configure your computer with a pre-assigned static IP address, follow the steps listed in
Section 3.1 for Windows XP running Service Pack 3 or skip to Section 3.2 for Windows7.
3.1 PC Static IP Address configuration – Windows XP with SP3
Follow these steps to set up a pre-assigned static IP address. The following static IP addresses
will be assigned to the PC:
IP address = 192.168.74.11
Subnet mask = 255.255.255.0
Gateway = 192.168.74.1

4. Define the static IP address configuration on your PC’s Ethernet port, select OK to
incorporate the settings.
Note: This value ranges from 0-255. It also
excludes the value already assigned to the
static IP address
