enclosure. The 2500/2500B comprises the following models
Note: When referring to both the 2500 and the 2500B this manual uses the term 2500/2500B. When
referring to one antenna or the other this manual uses the name of the specific antenna (2500 or
2500B).
The 2500/2500B smart antennas offer versatile, portable solutions with centimeter-level accuracy
powered by Hemisphere GPS’ Eclipse™ II multi frequency GNSS receiver technology.
With the Eclipse II GNSS OEM module, RTK performance is scalable. Utilize the same centimeter-level
accuracy in either L1-only mode, or employ the full performance of fast RTK over long distances with
L1/L2 GNSS signals.
The durable enclosures house the receivers, antennas, and optional radio modems, all in one package.
They can be powered through various sources, making the 2500/2500B ideal for a variety of
applications, where:

INSTALLATION
Before installing and using the GPS 2500/2500B Smart Antenna, read the following recommendations to
ensure the optimal life and accuracy of your antenna.
PROPER LOCATION
Note:
position based on measurements from each satellite to the internal GPS receiver.
An obstructed view of the sky will result in impaired system performance. The GPS engine computes a
Proper antenna placement is critical to positioning
accuracy. To select the proper antenna location:
1.Place the antenna with an unobstructed view of the
sky.
2.Mount the antenna on, or as close as possible to,
the center of your point of measurement.
3.Position the antenna as high as possible. The
picture shows the ideal location to place the antenna
on a vehicle.
MOUNTING THE GPS 2500 SMART ANTENNA
The GPS 2500 Smart Antenna features a built-in magnetic mount. For added versatility, the magnet can
be removed allowing the unit to be flush mounted if desired. Standard M6 size screws can be used for
mounting.
POWER CABLE SOURCE AND ROUTE
Review the following cautions before planning your power cable route.
• 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 cables 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 wraps.
WARNING:
Improperly-installed cables near machinery are dangerous.
POWERING THE GPS 2500 SMART ANTENNA
Use a 9 - 36 VDC power supply source for the GPS 2500 Smart Antenna. For optimal performance, use
a continuous and clean power supply.

NSTALLATION
WARNING:
Use a weather-tight connection and connector for outside applications.
To Power the GPS 2500 Smart Antenna
1. Connect the GPS 2500 Smart Antenna to a power source.
Note:
The GPS 2500 Smart Antenna features reverse polarity protection to prevent excessive damage if the power
leads are accidentally reversed.
2. Turn on the power source. The unit is ready to use.
Note:
The initial startup can take from 5 to 15 minutes depending on your geographic location. For example, it may
take up to 5 minutes to receive a full ionospheric map from SBAS to ensure optimum accuracy.
CONNECTING THE GPS 2500B SMART ANTENNA TO EXTERNAL DEVICES
The GPS 2500B Smart Antenna can communicate with a variety of external data loggers, navigation
systems, CAN systems and other devices through the provided circular connector.
The following is a list of commonly used communication protocols:
•
NMEA 0183:
Use either pins 2 and 3 (TxB/RxB) or pins 6 and 8 (TxA/RxA) in conjunction with pin 5 (Signal Ground)
to communicate with the receiver.
Use for sending and receiving messages to the receiver. Also use for updating firmware.
•
Binary:
•
CAN (NMEA 2000):
•
Radar-simulated pulse output:
Use for sending proprietary messages, such as those used in raw data logging or to update GPS
firmware.
Use for sending messages over a CAN bus. Use pins 4 and 9 for communicating
through CAN.
Use for relaying accurate ground speed. Pin 12 is the speed out pin. Pin
12 will output a square wave 10 with a 50% duty cycle. The frequency of the square wave varies directly
with speed. 94 Hz represents a speed of 1 meter per second, or a 28.65 pulse per foot traveled.
WARNING:
into your supporting hardware if you wish to utilize the Speed Radar Pulse output.
Pin 12 does not have any form of isolation or surge protection. You must incorporate isolation circuitry
You can mount the GPS 2500B in either of the following ways:
• Fixed base station
• Portable base station using the included tripod stem and adapter

To mount the receiver as a portable base station:
1. Thread the provided tripod stem onto the tripod adapter.
2. Mount the tripod adapter unit onto the tripod, leaving the adapter loose
on the tripod.
3. Thread the center hole of the receiver onto the tripod stem.
4. Position the receiver in the desired orientation and tighten the adapter
onto the tripod.
POWERING THE GPS 2500B
Depending on the parts included in your kit, you can the power
the receiver in either of the following ways:
• *12 V battery power cable (terminated with battery clips)
*You can use a 12 V car battery
The receiver is automatically on when connected to a power
source.
To connect a power source to the base station:
1. Connect the provided power cable to power port.
2. Attach the positive and negative leads at the opposite end of the power cable to the positive and
negative terminals of a car battery.
Check the Power LED—a red LED indicates a successful connection and the
receiver has power.
