Operating instructions

MOLLE MOUNT

POWERING KEYSTONE 6

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 a battery adapter.

ENABLING THE DATA FLOW

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 the USB type C cable.
With the Fischer EUD cable, devices with a 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.

Keystone app instructions

LAUNCHING THE KEYSTONE APP

Press OK to enable communication between the HUB and the HOST once the EUD is connected.

KEYSTONE APP OVERVIEW
Intuitive graphic interface with all essential information directly accessible on one screen.

Press f1 or 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 different 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 differentiation 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.

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:

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

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 type of battery is identified by a specific icon:

The following icon indicates that there is no connection to any power source on the considered port.

BATT AND RADIO/BATT STATUS

Press the BATT or RADIO/BATT icon when connected to a power source to access the following details:
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 you to switch from one power supply to another without any power loss.
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 activation of the logs allows to recording of all the parameters of energy consumption for post-mission analysis.
“AUTO CONNECT” will automatically enable communication with the HUB at connection without asking the user to confirm.
A night mode is available by pressing the DISPLAY THEME button.
When creating a profile, all current settings are saved and are associated with the newly created profile which automatically becomes the default profile.
Resetting the HUB will reboot the HUB, therefore data and power will be lost during the reboot cycle.
Resetting the KEYSTONE app will reset the HUB and return the system to initial factory settings. All profiles will be lost.

ATAK PLUG-IN

The KEYSTONE 6 can also be controlled through a plug-in in ATAK.

In ATAK the features have been reduced to the essential:

Power management of the PANs
Hot-swap function
