The integrated MOLLE mounts
allow the KEYSTONE 6 to be
attached to the soldier’s
vest in all four directions.
Operating instructions
MOLLE MOUNT

11
The KEYSTONE 6 can
be powered by a 10 to
20 V DC power source
on the RADIO/BATT port,
the BATT port
or both.
The Nett Warrior extension
cable can be used to
connect directly to a Nett
Warrior style battery or to a
battery adapter.
POWERING KEYSTONE 6

12
To establish the data flow
within the HUB, a host
device must be connected
to the EUD/HOST port.
Connect the End User
Device (EUD) to the Fischer
Nett Warrior plug to USB
type C cable.
With the Fischer EUD
cable, devices with an
USB-C interface can
leverage the KEYSTONE 6’s
built-in power delivery and
be charged.
NOTE: EUD cables with integrated Power Delivery
functionality are not compatible with KEYSTONE 6.
ENABLING THE DATA FLOW

13
Keystone app instructions
LAUNCHING THE KEYSTONE APP
Press OK to enable communication between the HUB
and the HOST once the EUD is connected.

14
KEYSTONE APP OVERVIEW
Intuitive graphic interface with all essential information
directly accessible on one screen.
·Press for Menu and Settings (refer to p.19)
·The icon indicates the internal microcontroller
temperature
·The KEYSTONE 6 has a self-diagnosis function.
The status ok icon will change to alerts when the
HUB is malfunctioning. Press the alerts icon to list
the dierent problems.

PANs STATUS
The power bar quickly
indicates the amount of
power consumed on the
PAN. This visual indicator
is completed by a
measurement in Watts.
PAN output status:
·Green light means
power is enabled, no
light means disabled
·The visual dierentiation
between VBATT and 5 V
DC is made by the size
of the indicators
Press the PAN icon to:
·Access the output
control by toggling
the VBATT and 5 V DC
buttons
·Display the voltage and
current measurements
of each output
·Modify the PAN name
by clicking on the text
field
NOTE: 5 V DC can be
disabled without cutting
data communication.

16
EUD STATUS
The KEYSTONE 6’s built-in bidirectional power delivery
function allows the EUD to be charged when the HUB
is powered by an external source, typically a battery,
but in the opposite case, the EUD can power the HUB
with 5 V DC only.
The power meter indicates the sense of the energy flow:
EUD on charge EUD providing power
Press the EUD icon to:
·Display the voltage and
current measurements
of the power lines
·Modify the EUD name
by clicking on the text
field

17
BATT AND RADIO/BATT STATUS
The light gray icon shows
the power source in
use. When it is a smart
battery, in addition to
the state of charge and
the voltage level, the
remaining operating time
is displayed.
The following icon indicates that there is no connection
to any power source on the considered port.
The type of battery is identified by a specific icon:
Smart battery with SMBus Simple DC source

18
BATT AND RADIO/BATT STATUS
Press the BATT or RADIO/BATT icon when connected
to a power source to access the following details:
An alert threshold can be
defined according to the
battery charge level. The
threshold is defined as
follows:
·in % for smart batteries
·in Volts for DC sources
Once reached, the battery
icon turns into orange.
The “Set as source”
button allows the user to
force the system to select
a power supply.
The use default source
button returns to the
default selection logic:
·In case the two
connected power
sources are of the same
nature, the RADIO/BATT
port is the default power
source.
·In case a smart battery
and a simple DC voltage
source are connected,
the simple DC voltage
source is the default
power source.
In all cases, the hot-swap
feature allows to switch
from one power supply
to another without any
power loss.
