====== System design ======
The encoder controller needs some prerequisites to be used. 
  * 5V power supply via microUSB socket
  * Ethernet network for communication
  * automatic IP-v4 address assignment via DHCP
  * Controller software

These necessary conditions can be fulfilled by the following devices:
  * USB plug-in power supply unit, USB hub with external power supply or USB connection of the PC
  * Ethernet switch provides the node between the encoder controller and the PC
  * DHCP server for automatic address assignment. A Router that provides an Internet connection has a DHCP server built in. This server assigns IP addresses to new devices in the network. Such a router does not need to have an Internet connection to use the DHCP function. Usually an Ethernet switch is integrated, which is sufficient for first tests.  
  * Alternatively, DHCP software can be installed on the Windows PC to implement such an IP address assignment.
  * The [[hardware:anleitungen:ardu-enc_en:enc-simcon_en|SimConnect Client]] or the [[hardware:anleitungen:ardu-enc_en:enc-plugin_en|X-Plane Plugin]] can be used as controller software.
