Description:

This document describes how to install the LANCOM Wireless ePaper Server on a Linux operating system.


Requirements:

  • LANCOM Wireless ePaper Server as of version 1.40 (download)
  • Intel dual core processor or equivalent
  • ARM architecture as of ARMv7 (e.g. Raspberry Pi 2 Model B)
  • 2 GB RAM (512 MB for the server)
  • 100 MB hard disk space for the server installation
  • Linux operating system
  • Java Runtime Environment version 7 or later



Procedure:

The Wireless ePaper Server is installed on a central computer on the network with constant access to the Wireless ePaper Displays.

  • Only one Wireless ePaper Server should be installed on a network, otherwise conflicts could arise.
  • Upto and including ePaper version 1.73 only the connectionless protocol UDP is supported. In the interests of system latency, the Wireless ePaper server and the access points have to be connected over the same local network.
  • As of the ePaper version 1.91 the connection oriented protocol TCP is supported. If TCP is used, the Wireless ePaper server and the access points can be located in different networks. More information regarding this topic can be found in this Knowledge Base article.



1) Download the installation package from the LANCOM website and unpack it to a directory of your choice on your Linux operating system. Use the following command to extract the package:

sudo unzip LANCOM-Wireless-ePaper-Server-1.101.0001-Rel.zip -d /opt

After executing this command, the folder opt contains the folder LANCOM-Wireless-ePaper-Server-1.101.9441.


2) The next step is to set up the daemon (service) that starts the Wireless ePaper Server:

2.1) First install the init script for the service. To do this, enter following command:

sudo cp /opt/LANCOM-Wireless-ePaper-Server-1.101.9441/LANCOM-Wireless-ePaper-Server /etc/init.d

This allows you to control the LANCOM Wireless ePaper Server (e.g. manual start/stop) by means of the init.d.

sudo /etc/init.d/LANCOM-Wireless-ePaper-Server [start|stop|restart|status]

2.2) This command enables you to set up an automatic start of the the Wireless ePaper Server.

sudo update-rc.d LANCOM-Wireless-ePaper-Server defaults

This command causes the server service to start automatically after a system boot.

You continue with the setup and management of the Wireless ePaper Server by using LANconfig on a Windows client on the network.
