Table 1-1: RX410p Components
Receiver
It is not necessary to mount the RX410p receiver. However, if mounting is desired, several thumb
screws, nuts, and brackets are provided in the kit. When choosing a mounting location, please
ensure the menu screen, LEDs, and buttons are visible and accessible. Access to the back panel
must be available for switching out cables and accessing the POWER button. There is an option
within the menu system to switch the direction of the display, so if it is easier to mount the unit upside
down, it may be mounted in that position and can still be easily operated.
NOTE: When mounting the receiver, mount the unit inside and away from the elements and in a
location that minimizes vibration, shock, extreme temperatures, and moisture.

To install the brackets for mounting:
1. Slide the nuts through the openings along the sides of the receiver.
2. Place the bracket along the receiver and insert the thumbscrews so they screw into the
nuts.
3. Secure the brackets in the location of choice.
Antenna
Placement of the antenna is crucial to the system’s operation. The GPS engine inside the antenna
computes a position based upon measurements from each satellite to the phase center of the
antenna. Mount the antenna at the desired location of reference. When choosing a mounting loca-
tion, make certain that there is a clear view of the sky. This will ensure that GPS satellites are not
masked by obstructions, potentially reducing system performance.
Mount the antenna on, or as close to, the center point of measurement of the vehicle. The antenna
can be mounted magnetically, on the vehicle’s surface, or on a pole.
Magnetic Mount
The magnetic mount can be secured by screwing it into the bottom of the antenna and mounting it to
any metal surface. A metal disc and foam adhesive is included with each magnetic mount. Use the
foam adhesive to bond the metal disc to the desired mounting location if there is no metal surface
available. To use the metal disc and foam adhesive:
1. Clean and dry the mounting surface on the vehicle.
2. Remove the backing from one side of the foam adhesive and press the metal plate onto the
mounting surface on the vehicle.
3. Remove the backing from the other side of the foam adhesive.
4. Press the metal plate onto the mounting surface of the vehicle.
5. Apply firm pressure to ensure good adhesion.
6. Place the antenna on top of the metal disc.
Surface Mount
As an alternative to the magnetic mount, the antenna is easily attached to the surface with four
machine screws (not included). To surface mount the antenna:
1. Photocopy the bottom of the antenna and use it as a template to plan the mounting hole
locations.
WARNING! Make sure the photocopy is scaled ONE TO ONE with the mounting holes on the
bottom of the antenna!
2. Mark the mounting hole centers as necessary on the mounting surface.
3. Place the antenna over the marks to ensure that the planned hole centers agree with the
true hole centers. Adjust as necessary.
4. Use a center punch on the hole centers in order to guide the drill bit.
5. Drill the mounting holes with a 3/16-inch /4.7625 mm bit appropriate for the surface mount.

6. Place the antenna over the mounting holes and insert the mounting screws through the
bottom of the mounting surface and into the antenna.
WARNING! Install the antenna only hand-tight. Damage resulting from overtightening the antenna
is not covered by warranty.
Pole Mount
The center thread of the antenna is 5/8 inches / 15.875 mm for compatibility with a survey pole (not
included).
CABLE INTERFACE
The power cable must reach an appropriate power source. The data cable may connect to a data
storage device, computer, or other device that accepts GPS data.
When choosing a route for all of the cables:
• Avoid running cables in areas of excessive heat
• Keep cables away from corrosive chemicals
• Do not run the extension cable through door or window jams
• Keep the cable away from rotating machinery
• Do not bend excessively or crimp the cables
• Avoid placing tension on the cables
• Remove unwanted slack from the extension cable at the receiver end
• Secure along the cable route using plastic wrap
WARNING! Cables improperly installed near machinery can be dangerous.
When connecting the various cables to different devices:
1. Connect the power cable to the appropriate power source.
2. Connect the antenna cable from the receiver to the antenna.
3. Connect the data port(s) to any required device.
EXTERNAL DEVICE CONNECTIONS
The serial ports of the RX410p operate at the RS-232C interface level to communicate with external
data loggers, navigation systems, and other devices. The two serial ports are accessible via the
back panel. The serial ports are accessible by two DB9 female connectors. Either serial port can be
used for firmware updates. Figure 1-3 illustrates the numbering for the DB9 connectors (female).

Figure 1-3: DB9 Socket Numbering
Note: For successful communication, the baud rate of the RX410p serial ports must be set to
match that of the devices to which they are connected. Tables 1-2 and 1-3 provide the
pin configuration for the serial ports.

Table 1-6: GPS Message Output Options
Serial Ports
The RX410p features two serial ports. The ports handle communications to and from the receiver
and antenna. The ports may be configured for a mixture of NMEA 0183, binary data, and RTCM SC-
104 data.
Custom Configuration of the RX410p
All aspects of the RX410p may be configured through the serial port with the use of GPS com-
mands. Many aspects of the receiver may also be configured.
Environmental Considerations
The RX410p receiver is designed to be placed indoors. It is, however, splash proof in case of acci-
dental exposure. The antenna is designed to be used outdoors.
NOTE: The changes made to the RX410p via the serial port will not be saved to memory for subse-
quent power-up unless a save command is issued ($JSAVE). If changes are made via the
menu system, they are saved automatically.
NOTE: Contact your local TeeJet Technologies dealer for additional information regarding the use
of GPS commands and customized configuration.

CHAPTER 2 - OPERATION
To power up the RX410p:
1. Connect the ends of the RX410p power cable to a clean power source providing between 8
and 36 VDC. The supplied power should be continuous and clean for best performance.
2. Turn on the system by pressing the ON/OFF switch on the back panel.
NOTE: A weather-tight connection and connector is suggested for use if the cable will be
located outside.
WARNING! Be careful not to provide a voltage higher than the input range (36 VDC). This will
damage the receiver and will void the warranty.
WARNING! Do not attempt to operate the RX410p with the fuse bypassed. Such a modification will
void the product warranty.
The RX410p features reverse polarity protection to prevent damage if the power leads are acci-
dently reversed. With the application of power, the RX410p will proceed through an internal start-up
sequence. However, it will immediately be ready for communication.
NOTE: The initial start-up can take from 5 to 15 minutes depending upon location. Subsequent
start-ups will output a valid position within 1 to 5 minutes depending on location and the
amount of time since the last start-up.
NOTE: The RX410p can take up to 5 minutes for a full ionospheric map to be received from
SBAS. Optimum accuracy will be obtained once the RX410p is processing corrected
positions using complete ionospheric information.
LEDS
The RX410p uses three LEDs. The LED functions are defined as:
• Power Indicator LED (red). This LED illuminates when the RX410p is powered.
• GPS Lock Indicator LED (yellow). This LED remains illuminated with the RX410p achieves
a solid GPS lock.
• DGPS Position Indicator LED (solid green). This LED remains illuminated in solid green
when the receiver has achieved a differential position and a pseudo range residual of better
than 32.8 feet / 10.0 meters. If the residual value is worse than the current threshold, the
green LED will blink, indicating that differential mode has been attained but that the residual
has not met the threshold.

10 Chapter 2 - Operation
MAIN MENU
The menu system of the RX410p is designed for easy setup and configuration in the field or in the
office. Most configuration can be completed entirely through the menu system without having to con-
nect to a computer or PDA. The menu software supports many different languages so individuals
with varied backgrounds can easily understand the configuration of the receiver. If at any time the
menu system needs to be reverted to system default, simply hold down the Enter button and power
on until the splash screen disappears.
The Up and Down Arrow buttons are used to navigate through the menu items. The Enter button is
used to enter into a sub-menu item or select the desired menu option.
