IMPORTANT FCC INFORMATION
The Federal Communications Commission has released Office of Engineering and Technology
Laboratory Division Knowledge Database (KDB) 44399, which refines the definition of Dynamic
Frequency Selection (DFS) support. Since this device has the ability to use frequencies covered
by DFS, KDB 443999 must be followed. It is published in full on the FCC web site:
https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=41732
In order to support FCC KDB 443999, Fortress has limited the use of certain frequencies within
the 5400–5725 MHz range. Specifically, the frequencies defined by the FCC as being of primary
interest are those in the 5600–5650 MHz range, which correspond to 802.11a channels 120, 124,
and 128. In order to comply with the KDB 443999, these channels have been removed from use,
or notched. Notched channels are unavailable for use on this device.
KDB 44399 provides additional restrictions on the use of channels within 30 MHz of notched
channels when the device is within 35 km of a Terminal Doppler Weather Radar (TDWR)
installation. Affected channels 116, 132, and 136 serve as a guard of 30 MHz around the critical
notched frequencies. Guard frequencies are unavailable for use on this device by default. The
FCC allows these channels to be used, however, as long as the device is not within 35 km of a
TDWR installation, as described in this excerpt of KDB 443999:
Any installation of either a master or a client device within 35 km of a TDWR location shall
be separated by at least 30 MHz (center-to-center) from the TDWR operating frequency.
In some instances it is possible that a device may be within 35 km of multiple TDWRs. In
this case the device must ensure that it avoids operation within 30 MHz for each of the
TDWRs. This requirement applies even if the master is outside the 35 km radius but
communicates with outdoor clients which may be within the 35 km radius of the TDWRs.
The requirement for ensuring 30 MHz frequency separation is based on the best
information available to date. If interference is not eliminated, a distance limitation based
on line-of-sight from TDWR will need to be used.
Please refer to the original KDB 443999 as posted on the FCC web site for the complete text.
In order to enable channels 116, 132, and/or 136, please contact Fortress to obtain a special
license. This license will be issued after it is confirmed that the installation is not within 30 MHz and

In addition, the FCC recommends that all operators and installers register with the WISPA
database used by government agencies to quickly find devices that may be causing interference
and notify their owners/operators to shut them down. This registration is not required, but Fortress
strongly recommends that all systems be registered, as described in this excerpt of KDB 44399:
A voluntary WISPA sponsored database has been developed that allows operators
and installers to register the location information of the UNII devices operating
outdoors in the 5470 – 5725 MHz band within 35 km of any TDWR location (see
http://www.spectrumbridge.com/udia/home.aspx). This database may be used by
government agencies in order to expedite resolution of any interference to TDWRs.
KDB 443999 further specifies that the requirements of KDB 594280 must also be met.
KDB 594280 is published in full on the FCC web site:
https://apps.fcc.gov/oetcf/kdb/forms/FTSSearchResultPage.cfm?switch=P&id=39498.
This device meets KDB 594280 by not allowing any configuration options to be made such that the
device could be taken out of compliance. There is no ability for the user to change country codes
or to select power levels that would take the device out of compliance.
For customers such as the U.S. military or others willing to produce evidence that particular
devices will be used only outside of the United States, a special license can be obtained from
Fortress that will allow those devices the option of selecting a different, non-U.S. country code.
Fortress creates such licenses only for those customers who offer proof of non-U.S. device usage,
and licenses are specific to particular devices and are not transferrable. Devices having such a
license should NOT be considered to be compliant with FCC regulatory requirements. Please
contact Fortress with questions about these special licences.
Only software that has been signed by Fortress using the Fortress private key can be loaded onto
a Fortress device, thus insuring that no software other than that which is controlled and signed by
Fortress can by loaded onto the device.

WARNING: If the
Mesh Point con-
nects to outside-mount-
ed antennas, failure to
provide a low resistive
earth ground can result
in migration of voltage
from lightning or line
surges onto the premis-
es wiring, which can
cause electric shock
and/or fire within the
building or structure.
Grounding: Ground the ES820 by mounting it with direct
contact to the vehicle chassis.
Radio Frequency: The Mesh Point’s internal radios conform
to the FCC’s safety standard for human exposure to RF
electromagnetic energy, provided that you follow these
guidelines:
Do not touch or move the antennas while the unit is
transmitting or receiving.
To safeguard Mesh Point transmitting circuitry, relocate
the Mesh Point and its antennas only when the Mesh
Point is powered off.
When the Mesh Point is transmitting, do not hold it so
that the antenna is very close to or touching any
exposed parts of the body, especially the face or eyes.
Antennas must be installed to provide a separation of at
least 20 cm (7.9") from all persons and any co-located
antenna or transmitter.
Regarding use in specific environments: · Do not
operate near unshielded blasting caps or in an
explosive environment. · Limit use in a hazardous
location to the constraints imposed by the location’s
safety director. · Abide by the rules of the Federal
Aviation Administration for the use of wireless devices
on airplanes. · Restrict the use of wireless devices in
hospitals to the limits set forth by each hospital.

3.2.1 Powering the Mesh Point On and Off
The single front-panel button powers the ES820 Mesh Point
ON and OFF.
If the Mesh Point is off, press the Power button to turn it on.
The Power LED will slow-flash green while the Mesh Point
boots, then light solid green for normal operation.
or
If the Mesh Point is on, press the Power button to turn it off.
The Power LED will go dark.
The power button is tied to pin 33 on the Mesh Point’s 37-pin I/
O connector, which is a power control line. Both switches must
be OFF to power the ES820 off.
3.2.2 Pushbutton Rebooting
Reboot (hard boot) the ES820 by powering it off and back on
again (described above).

4.1.3 Compliance and Standards
The Fortress ES820 is certified by the Wi-Fi Alliance® for the
following standards:
4.2 37-Pin Input/Output Connector
The connector on the rear panel of the ES820 provides all non-
radio input/output for the unit. In order to connect to the ES820,
a cable with a matching connector must be made, using the
required connector type:
Figure 4.1. MIL-DTL-38999 Series III TV Shell/Insert 15-35 (socket)
Table 4.1 defines the pin-out required for the ES820 cable
connector. Most definitions are standard (ex., Ethernet, serial,
and USB). Five pins are unique to the ES820:
Power (pin 33 - active lo) - powers the ES820 on and off.
When this pin is toggled lo, the unit is permitted to power up
and boot. The switch state is tied to the chassis ON/OFF
switch: both switches must be OFF to turn the unit off. Tie
this pin to a toggle switch.
Blackout (pin 24 - active lo) - controls blackout mode, which
turns all chassis LEDs OFF. When this pin is held lo, all of
the LEDs on the box are dark at all times. When the pin is
not held lo, LEDs revert to normal operation. This pin would
commonly be tied to a toggle switch.
emissions: CE, FCC, ETSI, MIL STD 464A, MIL STD 461F
immunity: MIL STD 461F
vibration: MIL STD 810G
IEEE: 802.11a/b/g
security: WPA™, WPA2™—Personal and Enterprise
EAP types: EAP-TLS, EAP-TTLS/MSCHAPv2,
PEAPv0/EAP-MSCHAPv2, PEAPv1/EAP-GTC,
EAP-SIM, EAP-AKA, EAP-FAST

RF Kill (pin 22 - active lo) - controls the RF Kill feature,
which turns all radio transmission OFF. When this pin is
held lo, all RF emissions are suppressed. When the pin is
not held lo, radios revert to normal operation, as defined by
the current configuration of the ES820. This pin would
commonly be tied to a toggle switch.
Reset (pin 23 - active on falling edge) - reboots the box.
Resetting is equivalent to power cycling the ES820. The
reset function is immediate: all current operations are
stopped and the ES820 restarts from the initial power-on
state. This pin would commonly be tied to a push button.
Zeroize (pin 32 - active on rising edge) - restores the
configuration to factory defaults. This pin activates on the
rising edge of the signal. The zeroize function is immediate
when the ES820 is powered on. If the ES820 is powered off
when the zeroize is pressed, the function is executed as
soon as power is applied. This pin would commonly be tied
to a push button.
The 37-pin connector provides support for six LEDs, five
controls, two Ethernet ports, one USB port, and one RS232
COM port.
