Introduction
This User Guide provides information about OrbitGPS’s Serial
GPS receiver forvehicle docking cradles formobile computers.
The OrbitGPS Serial GPS receiver is a SiRFstar III-based, WAAS-
enabled GPS receiver that collects GPS satellite data and
provides it to the mobile computer through the serial port of a
vehicle docking cradle. GPS information is available to the handheld computer when
docked. Two versions are available. One is powered by an external 12V cigarette lighter
adaptor and can be used with all MC900XX and MC70 vehicle cradles. The second
version can be used with MC70 cradle versions that output power through the serial
connector.
There are four versions of OrbitGPS’s Serial GPSreceiver:
G1010 – For use with all vehicle cradles. This version is powered by a 12V DC
“cigarette lighter” adaptor.
G1020 – For use with vehicle cradle with power out through the serial connector. This
version is powered through the DB9 serial connector used to connect the receiver to
the cradle’s serial port.
G1030 – For use with Blackbay’s VMC2500 vehiclecradleforthe Motorola MC70.
G1040 – For use with all vehicle cradles. This version is powered by a 12V/24V DC
direct-wire power adaptor withflying leads.
The OrbitGPS Serial GPS receiver outputs GPS information as industry standard NMEA
sentences which are compatible with most GPS software applications. It can also be
configured to output GPS information in the SiRF Binary format.

OrbitGPS’s GPS receivers offer typical accuracies of 3-5 meters uncorrected, and 3
meters or better with Wide Area Augmentation System (WAAS) correction.1They are
tested to comply with FCC and CE standards.
Note: Screens and windows pictured in this User Guide are samples and may vary.
Getting Started
Using the Serial GPS receiver with an existing GPS application
The Serial GPS receiver is designed to work “out-of-the-box” with GPS applications that
accept data in the NMEA protocol format.
The National Marine Electronics Association regulates the NMEA 0183 specifications
standard which defines a set of ASCII strings, called sentences, which relay GPS
navigation information. This is the most commonly used standard for GPS
communications.
To configure the Serial GPS receiver for use with a GPS application that supports the
NMEA protocol, set the following parametersin the GPS application:
GPS Com Port or Com Port: COM1
Baud Rate: 4800
Protocol: NMEA (Depending on the GPS application, you may not be asked to enter
the protocol.)
Once these parameters have been set, the GPS application should begin automatically
receiving GPS data from the Serial GPS receiver. Please consult the GPS application
documentation for further information on how to communicate with an attached GPS
receiver.
Using the Serial GPS receiver with AAS and EGNOS
The OrbitGPS Serial GPS Receiver is configured to receive GPS correction data from the
Wide Area Augmentation System (WAAS) and European Geostationary Navigation
Overlay Service (EGNOS) differential correction systems. Simply put,WAAS and EGNOS
broadcast additional correction data that is used to improve quality of the GPS data
provided by GPS receivers. The OrbitGPS Serial GPS Receiver will automatically acquire
and utilizethe correction dataof WAAS or EGNOS satellitesavailable inthe area of use.
For more information on WAASvisit:
http://gps.faa.gov/programs/waas/currentnews-text.htm
1*Accuracy is subject to degradation based on environmental and positional conditions. Rated accuracy provides 95%
Circle Error Probability (CEP position accuracies of <5 meters with WAAS correction and <10 meters uncorrected.

The OrbitGPS Serial GPS Receiver with cigarette lighter power adaptor (OrbitGPS Part
G1010) can be used with MC90XX S (Short) and K (Brick) and MC70 vehicle cradles. Set
up instructions are the same for all of these. In this installation, the GPS receiver draws
power from a 12V DC “cigarette lighter” adaptor. As long as the adaptor is powered, the
GPS receiverwill operate. As such, the DC power jack needsto drawuninterrupted power
from the vehicle for constant operation of the GPS receiver. Install the vehicle cradle
before connecting the OrbitGPS Serial GPS Receiver.
When attached to the vehicle dock, the Serial GPS receiver allows the mobile computer,
when docked in the cradle, tocaptureGPS data.

Connecting the OrbitGPS Serial GPS Receiver Serial Powered Version
(OrbitGPS Part Number G1020) to Intermec and Motorola Vehicle
Cradles
Motorola MC70 Cradle (VCD7000): The serial powered version of the OrbitGPS Serial
GPS Receiver (LP01632) can be used with RoHS-compliant versions of the MC70vehicle
cradle that offer power out through the DB9 serial connector. Consult Motorola
documentation to determine if you have a compatible cradle. In thisconfiguration, the GPS
receiver draws power from the MC70 mobile computer through the DB9 serial connector
and requires no additional power supply. As a result, the GPS is powered only when the
mobile computer is docked in the cradle and a valid GPS com port is open in a running
GPS application.If the mobile computer is undocked or goes into suspend mode, power is
no longer supplied tothe GPS receiver. This situation may lead to slightly longer GPS start
times when the mobile computer is docked or is resumed after a suspend. Install the
vehicle cradle before connectingtheOrbitGPS Serial GPS Receiver.
Intermec CN3 & 700 series: The serial powered version of the OrbitGPS Serial GPS
Receiver (LP01632) can be used CN3 and 700 series vehicle docks.
700 series – Use the serial port marked “A” on the back of the dock and follow the
instructions below. The serial GPS receiver will not operate if used with the serial port
marked “B.”
CN3 – To connect the serial GPS to the dock, you will need the Intermec serial
adaptor cable(Intermec part number 225-737-001).

(OrbitGPS Part Number G1040) to Vehicle Cradles
Step 1
To connect the Serial GPS to the vehicle cradle, plug the DB9 Serial connector into the
serial port found on the bottom of the cradleto the left of the power cable. Tighten the DB9
serial connector with the thumbscrews to ensure a secure connection.
Step 2: Installation instructions for direct wire power cable
Read the following instructions completely before beginning.
WARNING: A properly trained technician must perform the power connection.
Improper connection can damage the vehicleorGPS receiver.
To connect the GPS receiver power cable to power:
1. Locate theVehiclePower Source.
Note: An accessory output in the vehicle’s fuse panel is the ideal location for connecting
the power cable. The power cable should be added to a circuit with a maximum load
capacity for the GPS recevier and the original circuit. Refer to the vehicle’s owner’s
manual for identification of circuit. If a fused output is not available, an inline fuse holder
with UL-listed fuse should be used (fuse should be rated 4A for 24V operation and 5A for
12V operation). The fuse protects the vehicle from an electrical short on the power line to
the GPS receiver.
To provide constant power to the GPS receiver, shut the vehicle’s ignition, then connect
the power cable to unswitched power.
2. Route the power cable from the connection with the GPS receiver to the connection
point for thevehicle’s power source.
Caution: The means of routing and securing the power input cable from the GPS receiver
through to the vehicle power source is extremely important. Hazards associated with
improper wiring can be severe. To avoid unintentional contact between the wire and any
sharp edges, provide the cable with proper brushings and clamping where it passes
through openings. If the wire is subject to sharp surfacesand excess engine vibration, the
wiring harness can wear away, causing a short between the bare wires and chassis. This
can start a fire.
3. Prepare the cabletermination.
a. Red wire: connect to a +12/24V vehicle power source.
b. Black wire: connect tovehicle ground or chassis ground.
Note: How the cable terminates depends on the vehicle. If the vehicle has a power output
connector, attach a mating connector to the end of the power cable. You may be able to
connect to a fuse panel with a simple blade terminal or commercially available connector.

Raw Data
Fix Description
At the lower portion of the screen, just above the Tools menu, the GlobalPoint GPS
application displays the type of fix currently acquired by the GPS receiver. This value can
change over time as the receiver’s viewable sky changes, or if the receiver is re-initialized.
The types of fixes are:
Invalid unavailable solution – This signifies that not enough satellite data is available
to provide a fix. This occurs as the receiver is initialized or when an insufficient
number of satellitesare in the viewable sky.
Corrected 3D point solution – This signifies that a three-dimensional GPS fix is
available and that it is corrected using WAAS or EGNOS. If available, WAAS
satellites are displayed in the satellite view as satellite numbers 35, 47. 48 and 51.
EGNOS satellites are displayed as 33. 37, 39 and 44.
Uncorrected 3D point solution - This signifies that a standard three-dimensional GPS
fix is available.
Uncorrected 2D point solution – This signifies that a two-dimensional GPS fix is
acquired.

Latitude – Displays the current location on the face of the Earth north or south of the
Equator. Latitude is an angular measurement ranging from 0°at the Equator to 90°at
the poles (90º N or 90º S). In the GlobalPoint GPS application, North is shown as a
positivevalue and South is show as a negative value.
Longitude – Displays the current location on the face of the Earth east or west of a
north-south line called the Prime Meridian. Longitude is an angular measurement
ranging from 0°at the Prime Meridian to +180°east ward and −180°westward. In the
GlobalPoint GPS application, East is shown as a positive value and West is show as
a negativevalue.
UTC – “Coordinated Universal Time or UTC,” is the equivalent of Greenwich Mean
Time, the astronomical basis for civil time.
Quality – Displays whether current fix is a “Normal” uncorrected fix or a WAAS
“Corrected” fix.
HDOP – “Horizontal Dilution Of Precision” is a measure of how the satellite geometry
influences the latitude and longitude data accuracy. A good satellite geometry and
hence a good accuracy is obtained if the satellites being tracked are located as far
away from each other as possible, while the geometry is poor if the satellites are
locatedclose to each other. If the HDOPvalue ishigher than about 10 the latitude and
