GSR2700 ISX Operations Manual 1
Introduction
This manual provides complete information about your
GSR2700 ISX receiver and its functions, including components,
system setup, operations, and data collection.
1.1 About the GSR2700 ISX
The SOKKIA GSR2700 ISX is a fully integrated, high-precision
GNSS solution for use in both RTK and post-processing
applications. It integrates a dual-frequency receiver, antenna,
memory, batteries, wireless connectivity, and a differential
correction radio into one compact enclosure.
For wireless connectivity, the GSR2700 ISX supports Bluetooth®
wireless technology to allow you to communicate with other
Bluetooth-enabled devices (for example, your handheld data
collector), providing a completely cable-free option.
For differential correction transmission flexibility, the
GSR2700 ISX uses either an internal UHF or GSM/GPRS radio. It
also offers the innovative feature of voice messages to indicate
receiver status during field operation.
Surveyors can use the GSR2700 ISX for topographic, stake out,
and control surveys. Excellent acquisition and reacquisition times
mean this receiver continues to excel in environments where
signal obstructions are present and frequent interruptions of
signals can be expected.
The GSR2700 ISX features a rugged design for use in adverse
environments, and it is engineered to provide years of reliable
operation.
You can also use the GSR2700 ISX handheld component (SDR+)
and desktop post-processing software (Spectrum® Survey Suite)
with the GSR2700 ISX. When used together, these components
provide a powerful, flexible, and easy-to-use GNSS system.

CAUTION
A caution provides information about
possible sources of difficulty or situations
that may damage the product.
CAUTION
• If your receiver has an internal radio, always ensure that the
radio antenna is properly connected to your receiver before
turning the unit on.
Never disconnect the radio antenna while the internal radio
is still powered. Disconnecting the antenna while the
receiver is on may cause irreparable damage to the
internal circuitry of your radio, particularly when the radio is
transmitting information.

GSR2700 ISX Operations Manual 7
Introduction Chapter 1
• If travelling with or shipping the GSR2700 ISX by air, ensure
that you remove the tripod or survey pole, or any other
mount component from the socket on the receiver’s
underside (Figure 5, Receiver Underside View, page 10).
The receiver contains a vent that is designed to equalize
pressure inside the housing. If any component is in the 12
cm (5/8") thread mount socket, air flow to the pressure vent
may be limited or blocked and internal damage could occur
to the receiver.
• This receiver incorporates circuitry to absorb most static
discharges. However, severe static shock may cause
inaccurate operation of the unit. Use anti-static precautions
where possible.
• This device is a precision instrument. Although it is
designed for rugged operating conditions, it performs best
when handled with care.
• When the port covers are closed, the enclosure is sealed to
provide protection against adverse environmental
conditions. To minimize the possibility of damage, always
keep the ports covered except when in use.
• The GSR2700 ISX can accept an input supply voltage in the
range of +9 to +18 VDC. Do not operate the receiver
outside the specified voltage range.
• Drawing more than the specified maximum current (1 amp
combined total) from the two COM ports will cause an
internal fuse to interrupt the current to prevent damage to
the unit. If this happens, immediately reduce the load and
allow the unit to automatically reset its protection circuitry.
• Always use the correct cables with the receiver and handle
them correctly (don’t pinch or bend sharply). Failure to do
so will damage the receiver, and void the unit’s warranty.
CAUTION

GSR2700 ISX
Components
The GSR2700 ISX enclosure is fully sealed and houses your
system’s GNSS receiver, antenna, batteries, memory, internal
radio (if installed), and wireless communication device. The
integration of components into a single enclosure makes it
unnecessary to use a backpack.
2.1 Enclosure Features
The top of the GSR2700 ISX encloses the antenna and radome,
surrounded by a shock-absorbing protective bumper.
One side of the receiver shows the radio antenna port and the
display panel (see Figure 4), which you can use to control and
monitor the system.
Brightly colored LEDs display the status of your system.

CAUTION
If travelling with or shipping the
GSR2700 ISX by air, remove the tripod or
survey pole from the survey mount socket
(see #1 in Figure 5). This will prevent any
damage that can occur if the pressure vent
inside the receiver is blocked.
