 We used the following components to build up our client infrastructure. Note that links provided are just proposals for your convenience, other components will also work.
   - a FLARM device
-  - a power adapter and data cable for the FLARM device, we use currently this [http://shop.segelflugbedarf24.de/product_info.php?info=p32_Update-Cable-RS232.html update cable]
-  - a [http://www.raspberrypi.org Raspberry PI]
-  - a USB charger to power the Raspberry, just make sure it can deliver at least 1000mA
-  - optional, recommended for a stationary installation: we use currently an [http://shop.segelflugbedarf24.de/product_info.php?info=p29_FLARM--Outside-Antenna-4-m-cable.html external antenna]
+  - a [http://www.raspberrypi.org Raspberry PI] 
+  - Power supply:
+   - As Flarm is running on 12V and to ease use of a mobile flarmradar gound station powered by a 12V battery, we recommend a 12V power supply for the flarmradar ground station (FGS)
+    - Use a standard power converter (e.g. [http://de.rs-online.com/web/p/steckernetzteile/6666928/ RS-Online]) if an electical outlet is available to power the FGS
+    - For battery powered FGS, use a 12V battery as used in most gliders
+    - To connect the FGS to external power supply or battery, use a connector, which is protected against polarity reversal (e.g. [http://de.rs-online.com/web/p/dc-buchsen/7684419/ RS-Online])
+    - To protect your Flarm against over current, a 500mA fuse should be installed in the power supply route to the Flarm (e.g. [http://de.rs-online.com/web/p/sicherungshalter-fuer-frontplattenmontage/3595961/ RS-Online])
+    - To connect your Flarm to the FGS, we recommend installing a RJ45 connector on the FGS front panel and to use a short network cable to connect the FGS to the Flarm
+    - For pin assignment of the RJ45 please consult [http://www.flarm.com/support/manual/FLARM_InstallationManual_v5.00E.pdf Flarm Installation Manual] 
+    - Wiring instructions: 12V DC In --> Flarm fuse --> RJ45 connector --> network cable --> Flarm 
+    - Alternative way of Flarm power supply: [http://shop.segelflugbedarf24.de/product_info.php?info=p32_Update-Cable-RS232.html update cable]
+   - Raspberry is running on a 5V power supply therefore the 12V power supply must be converted to 5V for the Pi.
+    - Power conversion can be performed using DC/DC converter. Make sure the DC/DC converter can deliver at least 1A.
+    - To protect your Pi against over current, a 500mA fuse should be installed in the power supply route to the Pi (e.g. [http://de.rs-online.com/web/p/sicherungshalter-fuer-frontplattenmontage/3595961/ RS-Online])
+    - Use a Micro-USB connector to feed the power into your pi
+    - Wiring instructions: 12V DC IN --> Pi Fuse --> DC/DC converter --> Micro-USB connector --> Pi 
+    - Alternative way of Pi power supply: A USB charger to power the Raspberry, just make sure it can deliver at least 1000mA
+  - Flarm <--> Pi Data connection
+   - Flarm delivers RS232 signal on its data port. To feed this signal into the Pi, there are presently two alternatives
+   - RS232-USB-cable: Buy a RS232 to USB converter cable. Preferable one which uses the FTDI chipset (e.g TBD). If you use a different chipset, this may not be supported by default by the Pi operating system.
