Chapter 4 Using the MPC

Before using MPC for the first time, ensure that you have follo wed the installation instructions of

Chapter 2, Quick Start and Chapter 3, MPC Setup Considerations, starting on Page 16.

CAUTION!: See the cautions o n Page 11 of the Notice for a list o f items you should b e aware

of as you set up and use the MPC.

4.1 Self-Test

When power is applied, it take s several minutes for the computer within the MPC to boot up. It takes

up to 15 minutes for the internal OCXO to warm up to a point where the frequency is stable enough to

track satellites.

Once powered and st able, the MPC performs the first phase of self-test functions. If no problems are

detected, the STATUS LED on the front of the MPC will glow green. You can monitor the MPC using

the VFD pan el Statu s menu and/o r RXSTATUS l og. Self-test status of the internal GPSCard can be

examined via the self-status word in the RANGE and RXSTATUS data logs, refer to Volume 2 of the

OEM4 Users’ Guide.

System and l ogging st atu s reports may also be seen via the internet on the Modula te d Precis i on Cl ock

website, see Section 6.2, MPC Firmware Upgrades & Updates starting on Page 75.

If the MPC fails its self-test, please refer the problem to your dealer or NovAtel Customer Service.

4.2 Configuring the Network

There are three connectors on the back panel of the MPC that allow connectivity to the internet:

• Ethernet

• Modem

• Direct (PPP)

These MPC internet ports, user security, and internet method can be configured using the menu s on

the front panel of the MPC. A limited amount of the system status may also be viewed in these menus.

See Chapter 5, VFD Menus on Page 40 for more details.

How to set up the different ports for connection to the internet and then how to connect to the internet

from each port is described in the follo win g s ections.

4.2.1 Ethernet Connect

The Network Administrator must use the Configure Ethernet menus as described in Section 5.2.4,

Configure Ethernet on Page 46 to decide whether or not the IP address is assigned automatically via a

Dynamic Host Configuration Protocol (DHCP) server on the local network (intranet). If AUTO IP in
