Introduction
This section provides information on mounting the VR500 in the optimal
other mounting options.
GNSS satellite
When considering where to mount the VR500, consider the following
Figure 2-1: Recessed arro w
location, orientation considerations, environmental considerations, and
reception
satellite reception recommendations:
• Ensure there is a clear view of the sky available to the VR500 so the GNSS
and L-band satellites are not masked by obstructions that may reduce
system performance
• Mount the VR500 in a position in respect to the primary GNSS antenna
(located on the end opposite the recessed arrow on the underside of the
enclosure)
• Locate any transmitting antennas away from the VR500 by at least a few
meters to ensure tracking performance is not compromised
• Ensure cable length is adequate to route into the machine to reach a
breakout box or terminal strip
• Do not locate the antenna where environmental conditions exceed those
specified in Appendix B, Technical Specifications of this document.

Ports
Overview
The VR500 offers serial port, CAN, and Ethernet port functionality.
Serial ports
The VR500 has two serial ports:
Note: The VR500 has maximum baud rate of 115200.
Serial port
You may configure Port A or Port B of the GNSS receiver to output any
they are connected. Flow control is not supported.
• Port A can be both full-duplex RS-232 and half-duplex RS-422 (transmit
only)
• Port B is full-duplex RS-232 or RS-422
You can receive external differential corrections via either Port A (full-duplex
RS-232) or Port B (full-duplex RS-232 or full-duplex RS-422). You can connect
up to three devices at one time using two ports.
One device can receive data via Port A (RS-422 transmit only) while two
devices can transmit and receive data via Ports A and B (one connected to
Port A RS- 232 and one connected to Port B).
You can update firmware via Port A (RS-232) or Port B.
configuration
combination of data.
Port A can have a different configuration from Port B in data message
output, data rates, and the baud rate of the port, and configure the ports
independently based upon your needs. Both RS-232 and RS-422 output
signals may be used simultaneously.
The RS-232 Port A and RS-422 Port A output the same data messages at the
same baud rate. If the baud rate or messages for the RS-422 port need to be
changed, this needs to be commanded through the RS-232 port.
Note: For successful communications, use the 8-N-1 protocol and set the
baud rate of the VR500’s serial ports to match that of the devices to which

can bring the cable into a break-out box that incorporates terminal strips,
within the machine.
When lengthening the cable keep the following in mind:
• To lengthen the serial lines inside the machine, use 20-gauge twisted pairs
and minimize the additional wire length.
• When lengthening the power input leads to the VR500, ensure the
additional voltage drop is small enough that your power system can
continue to power the system above the minimum voltage of the system.
Wire of 18-gauge or larger should also be used.
Note: Using the adapter will cause you to lose ethernet capability.

The VR500 automatically scans and tracks SBAS signals without the need to
tune the receiver.
The VR500 features two-channel tracking that provides an enhanced ability
to maintain a lock on an SBAS satellite when more than one satellite is in
view.
This redundant tracking approach results in more consistent tracking of an
SBAS signal in areas where signal blockage of a satellite is possible.

station (primary receiver) that broadcasts corrections over a wireless link to
the rover (secondary receiver).
The VR500 can use RTK through either serial port or its internal UHF radio.
The receiver uses any RTK message coming in over a serial port if the RTK
message type is included in the list of available differential sources.
If you do not know which RTK message type is being sent by the base station,
you can include RTCM3, ROX, and CMR.
Including extra differential sources will not affect the receiver if those
differential sources are not being received.
After setting the differential source configure the baud rate of the serial port
receiving the RTK corrections. Ensure that the serial port configuration of the
external device (such as radio or modem) is 8 bits/byte, 1 stop bit, no parity
and no flow control.
Connect the external device to the serial port of the VR500. Some cables may
require the use of a gender changer and/or null modem adapter. For

The VR500 has an integrated gyro and two tilt sensors, which are enabled by

default. Each supplemental sensor may be individually enabled or disabled.
Both supplemental sensors are mounted on the printed circuit board inside
the VR500.
The sensors act to reduce the RTK search volume, which improves heading
startup and reacquisition times. This improves the reliability and accuracy of
selecting the correct heading solution by eliminating other possible,
erroneous solutions.
The Hemisphere GNSS Technical Reference Manual describes the commands
enabled by default and constrains the RTK heading solution beyond the
volume associated with a fixed antenna separation.
The VR500 knows the approximate inclination of the secondary antenna with
respect to the primary antenna. The search space defined by the tilt sensor is
reduced to a horizontal ring on the sphere’s surface by reducing the search
volume and decreases startup and reacquisition times (see Figure 3-2).

shortens reacquisition times when a GNSS heading is lost due to blocked
satellite signals.
The gyro provides a relative change in angle since the last computed heading,
and, when used in conjunction with the tilt sensor, defines the search space
as a wedge-shaped location (see Figure 3-3).
Figure 3-3: VR500 gyro aiding
The gyro aiding accurately smooths the heading output and the rate of turn,
and provides an accurate substitute heading for a short period depending on
the roll and pitch of the machine (ideally seeing the system through to
reacquisition).
The gyro provides an alternate source of heading, accurate to within 1º per
minute for up to three minutes, in times of GNSS loss for either antenna. If
the outage lasts longer than three minutes, the gyro will have drifted too far
and the VR500 begins outputting null fields in the heading output messages.
There is no user control over the timeout period of the gyro.
The gyro initializes itself at power up and during initialization, or you can
calibrate it as outlined in the Hemisphere GNSS Technical Reference Manual.
For optimal performance, when the gyro is first initializing, the dynamics the
gyro experiences during this warm-up period are similar to the regular

degree of smoothing to the heading, pitch, Rate-of-Turn (ROT), Course-overGround (COG), and speed measurements.
You can adjust these parameters depending on the expected dynamics of the
machine. For example, increasing the time is reasonable if the machine is
very large and is not able to turn quickly or would not pitch quickly. The
resulting values would have reduced “noise,” resulting in consistent values
with time. If the machine is quick and nimble, increasing this value can create
a lag in measurements.
Formulas for determining the level of smoothing are located in the
Hemisphere GNSS Technical Reference Manual. If you are unsure how to set
true heading measurement provided in the $GPHDT message. The default
value of this constant is 0.1 seconds of smoothing when the gyro is enabled.
The gyro is enabled by default but can be disabled.
By disabling the gyro, the equivalent default value of the heading time
constant would be 0.5 seconds of smoothing. This is not automatic, and
therefore it must be manually entered.

until the screen illuminates.
The VR500 accepts an input voltage of 9to 32 VDC via the power cable. The
supplied power should be continuous and clean for best performance. Refer
to Appendix B for the power specifications of the VR500.
Do not apply a voltage higher than 32 VDC. This will damage the receiver
and void the warranty. Also, do not attempt to operate the VR500 with the
fuse bypassed as this will void the warranty.
The VR500 features reverse polarity protection to prevent damage if the
power leads are accidentally reversed. Although the VR500 proceeds through
an internal startup sequence when you apply power, it will be ready to
communicate immediately.
Initial startup may take 5 to 15 minutes depending on the location.
Subsequent startups will output a valid position within 1 to 5 minutes
depending on the location and time since the last startup.
The VR500 may take up to 5 minutes to receive a full ionospheric map from
SBAS. Optimum accuracy is obtained once the VR500 is processing corrected
positions using complete ionospheric information.
