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. Base 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 EE240 does not have a data logger.
For a detailed technical description, see chapter 3.1 Base Station.

FUNCTION DESCRIPTION / INSTALLATION
3.1
Base Station
Depending on the application two different systems can be set up:
1) "Point–to-Point" (EE241 with a single transmitter)
This setup offers a cost friendly solution to transmit wirelessly a few measurement values
(e.g. a temperature and a humidity measurement).
The EE241 can communicate with only a single transmitter EE244, in between the two any
desired number of routers can be installed to increase the transmission distance.
The EE241 has for each measured value only one channel available (temperature,
humidity, CO2). E.g. it is not possible to transmit two temperature signals simultaneously.
There is no personal computer necessary to configure the EE241 – the desired setup is
configured by E+E in accordance with the ordering code.
2) "Wireless Network" (EE242 with multiple transmitters)
With the EE242 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.
