Introduction
This Quick Guide is a short summary of the most important features of the
GNS5894TAC StarterKit. The complete User Guide is currently not yet
available and will be completed shortly.
This manual shows how to connect the GNS5894TAC StarterKit to a PC in order to
verify GNS 5894TAC Mode-S-A-C all-in-one module performance and test supported
features.
For technical specification, please refer to the GNS5894T_ADSBModul_datasheet.
The GNS5894TAC is a software extension of the GNS5894T, which is additionally able
to receive Mode A/C data. The hardware of the GNS5894TAC is unchanged. For this
reason the GNS5894T_ADSBModul_datasheet can be used as long as no description of
the Mode A/C extension is available.
Connected to a PC, all Mode-S & Mode-A/C Data is routed to the miniUSB port.
GNS5894TAC StarterKit Features
 Power supply via Mini-USB socket
 Access to all signals of the GNS5894TAC via pin header contacts.
 PC data connection via the integrated USB to UART converter or direct access to the serial
interface (3.3V) of the GNS5894TAC for connection to other data processing devices.
 5V DC input via mini USB
 2 SMA antenna connectors for 1090MHz and GNSS RF In
 GNSS active antenna, DC supply (3.3V)
 ADS-B “frame indicator”
