STARTING UP THE WIRELESS SYSTEM
There is no personal computer necessary to configure the EE241 – the desired setup is
configured by E+E Elektronik in accordance with the ordering code.
Necessary steps to start up the system:
1) Establish the power supply to the base station.
2) Connect the sensing probe to the transmitter, either direct or with a sensor cable.
3) Establish the power supply to the transmitter (4 Alkaline 1.5 V, AA batteries, in the scope
of supply).
Remove the transportation insulation-strip in the battery compartment first, to activate
the transmitter.
4) Establish the wireless connection:
Press the push-button “Connect” for 3 seconds
Immediately the base station switches to the ‘Connect-Mode’ and searches for active
transmitters – for 30 seconds. The LED next to the push-button lights up to indicate the
‘Connect-Mode’ is active.
Within these 30 seconds, the push-button “Connect” on the transmitter must be pressed
for 3 seconds to establish a connection. As soon as the base station recognizes the
wireless signal from the transmitter, the addresses of the devices are automatically
exchanged and the wireless connection established.
5) Checking the active wireless connection:
- Base station
The wireless connection is active, as soon as the measurement data is available
(display, analogue output).
- Transmitter
The wireless connection is active, as soon as in the display the symbol >< is
continuously illuminated (see chapter 3.2.3. Operating Components, under 3. Display).
6) Alterations of the configuration of the transmitter:
The transmission interval is set at a default of 5 minutes. To increase the operating life
of the batteries the transmission interval can easily be altered with the rotary switch
“TIME” in accordance with the interval-time table, see chapter 3.2.3 Operating
Components, under 1. Rotary Switch “TIME”.
4.1 “Point-to-Point” (EE241 with a single transmitter)
4.2 “Wireless Network” (EE242 with multiple transmitters)
In order to register the transmitter EE244 to the network through the router the following
steps have to be taken:
a) Register the router:
Press the push-button “Connect” on the base station for 3 seconds.
Within 30 seconds, the push-button “Connect” on the router must be pressed for 3 seconds
to establish a connection. As soon as the base station recognizes the wireless signal from
the router, transmitters can be added and connected through the router.
b) Register transmitters to the network through the router:
Press the push-button “Connect” on the base station for 3 seconds.
Within 30 seconds, the push-button “Connect” on the transmitter must be pressed for 3
seconds to establish a connection. As soon as the base station recognizes the wireless
signal from the transmitter, the addresses of the devices are automatically exchanged and
the wireless connection established.
4.3 Increasing the Transmission Distance with Routers
For the configuration of the EE242 a personal computer is needed (with admin authoriza
-
tion), to manage all transmitters and to configure the analogue outputs of the base station.
1) Preparing the hardware:
Attention: the base station can handle a maximum of 10 wireless signals (transmitter or
router). If more than 10 transmitters are needed, an extra router will extend the network
further (for details, see chapter 3.3. Router).
2) Preparing the personal computer and software:
No disk space is needed on the personal computer, because the EE242 is equipped
with a web server.
3) Configuration of the wireless network:
- Connect the base station with the personal computer by way of the Ethernet
connection and adjust the network settings (see chapter, Configuration Software).
- Start the internet browser (Internet Explorer, Firefox, ….).
- Enter the default IP-address (//192.168.0.64) of the EE242 in the address line.
4) Check the active wireless connection, see chapter 4.1 “Point–to-Point” (EE241with a
single transmitter), under 4).
5) Changing the configuration settings of the transmitter and the base station, see chapter
Configuration Software.
