1.2: General Description
The SIR 4000 is a lightweight, portable, ground penetrating radar system that is ideal for a wide variety of
applications. It is designed to operate GSSI single digital antennas, single analog antennas, or dual
frequency antennas. The system will not support the simultaneous operation of a digital and analog
antenna. The various components of the SIR 4000 are described below.
The major features of the control unit are the keypad, control knob, 10.4 inch LED display with 1024 by
768 pixel resolution, connector panels (HDMI Video Out, USB 2.0, Ethernet, Serial Port I/O, digital and
analog antenna connectors, power, GPIO Connector, micro-USB), battery slot, and indicator lights. The
display screen allows you to view data in real time or in playback mode. It is readable in bright sunlight,
although a sunshade for the unit is available. Prolonged exposure to direct sunlight will cause the screen
to heat up and may affect screen visibility.
There are two latching panels on the sides of the unit. These contain the battery slot, Micro-USB port, and
Ethernet port. To open the panels, rotate the locking pin counter-clockwise until it is loose. To close the

1.3 Cautions and Warnings
1The Display Screen: Do not use alcohol to clean the display screen as this may damage the rubber
gasket around the screen and impact the IP rating. GSSI recommends using warm water or Windex
(or another ammonia-based) cleaner. There is not an anti-glare coating on this screen as there was
with the acrylic SIR 3000 screen protector. The screen is protected by a non-removable chemically
hardened glass.
2Power off before connection/disconnecting an antenna: GSSI recommends turning off the
SIR 4000 before connecting or disconnecting an antenna. Failure to do so may cause internal damage.
3Weatherproofing: The SIR 4000 is IP65 rated when all doors are closed and connections are
correctly made. If it does get wet internally, immediately power down the system and open all doors
and connections. Leave it for a minimum of 12 hours in a warm dry place. The SIR 4000 is factory
sealed and no attempt should be made to open it.
4USB Ports: Do not plug two USB drives into the SIR 4000 at the same time. This includes the USB
2.0 Port and the Micro USM Port. You can have a USB device, such as a keyboard or mouse, plugged
in at the same time as USB drive. Unlike the SIR 3000, the USB ports must not be used to connect
the SIR 4000 directly to a computer. This does not provide any additional functionality.

Model on the Antenna button and access to the menu will be disabled. This menu is also disabled when
no antenna is connected.
If an older analog antenna is connected to the SIR 4000 you will be able to select from a list of antenna
frequencies.
Antenna Type:Choose an antenna frequency from the list of available frequencies.
Antenna Model: If multiple models of the chosen Antenna Type are available, you can select which
model of antenna is connected. The antenna model is shown on a sticker affixed to the antenna housing.
Antenna Transmit Rate: The
antenna transmit rate is in KHz, with
a Custom rate capped at 100 KHz.
You can modify the antenna transmit
rate if Antenna Type is set to
Custom. A higher transmit rate
enables faster data collection and
more stacking to reduce random
noise. Some of the older antennas
are not capable of transmitting at
high speeds and setting them at a
high transmit rate may cause an
error. Consult your antenna
documentation or call GSSI Tech
Support if you have any question
about transmit rate. All GSSI 5100 and 52000 series antennas (2.6 GHz, 2.0 GHz Palm, 1.6 GHz,
1.5 GHz, 1.0 GHz, 400 MHz, 270 MHz, 200 MHz) can be operated at 100-200 KHz. Rates are limited per
regulations of the region where the unit is operated. If you are using another GSSI antenna, consult
