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).
Sensing probes cannot be connected to the router.

STARTING UP THE WIRELESS SYSTEM
4.1
Necessary Steps to Start up the System
For the configuration of the EE242 a personal computer is needed (with admin authorization), 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. Establish the power supply to the base station.
3. Connect the sensing probe to the transmitter, either direct or with a sensor cable.
4. Establish the power supply to the transmitter 4 x 1.5 V, AA/LR6 alkaline batteries
(not in the scope of supply).
5. Establish the wireless connection: Press the push-button "Connect" for 3 sec.. Immediately the base
station switches to the 'Connect-Mode' and searches for active transmitters – for 30 sec.. The LED
next to the push-button lights up to indicate the 'Connect-Mode' is active. Within these 30 sec., the
push-button "Connect" on the transmitter must be pressed for 3 sec. 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.
6. 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).
7. 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".
8. Preparing the personal computer:
- PC with admin authotization, no disk space is needed on the personal computer, because the
EE242 is equipped with a web server.
- crossover cable (PC-EE242: HA010333) for connecting directly with the EE242 or Switch and two
network cables.
