2.2.3  Router

The router is designed to increase the overall transmission distance and to bypass obstacles. Each  

router has the ability to receive and transmit a maximum of 10 signals (transmitter or another router). It 

is not possible to connect measuring probes to a router.  For a detailed technical description, see  

chapter 3.3 Router

2.2.4  Basis Station

The base station processes the data of the sensing probe and output an analogue or digital signal. 

Each base station has four analogue outputs and a (optional) display. The base station of the series 

E240 provides the most recent measurement readings via Modbus (ASCII, RTU, TCP), JSON and four 

analogue outputs. For a detailed technical description, see chapter 3.1 Base Station.

3  FUNCTION DESCRIPTION / INSTALLATION

3.1  Base Station

With the EE242 base station a comprehensive wireless network can be build. The network can consist 

out of 500 transmitters and 50 routers. Each base station can receive a maximum of 10 signals (router 

or transmitter) The Ethernet interface, Modbus and Webserver allow for easy configuration of the 

 

system as well an easy integration in existing networks.

3.1.1  Installation

The housing can be installed on DIN-rail. 

To remove from the rail, both orange snap locks can be opened with the use of a screwdriver.
