The following chapter describes an example of the procedure for setting
the address, confi guring and connecting the devices for the creation of
a wireless domain connectable to a Master controller using the CAREL
protocol (pCO, PlantVisor, PlantWatch,...).
The procedure includes:
1.
setting the address of the access point
2.
setting the address of the terminals
3.
setting the address of the sensors
4.
connecting the modes. In this phase, the terminals and the sensors
are associated with the access point.
3.1 Example of the wireless network
•
1 Access point (EW00AB2020)
•
1 Repeater (EW00RB2020) (if necessary)
•
2 Terminals (EW00T*)
•
2 Sensors (EW00S*)
3.2 Setting the addresses
This is a fundamental phase in setting up the system, and allows each
device to be identifi ed uniquely.
Important : the address can only be set at this time. Any changes,
when the channel has been set (see Automatically search for
wireless communication channel), will be ignored. The address can only
be changed after having reinitialised the device (see Resetting the
devices).
Access point
•
Power up the access point;
•
check that LED L1 (yellow) on the left is always on and the others are
off . If the LEDs are not in this status, reinitialise the access point (see
Resetting the devices);

•
Set the desired CAREL network address using the 4 dipswitches (0 =
OFF; 1 = ON), as shown in the table.

(*)The address can be set but the device will not respond to the requests
from the Master.
Automatically search for the wireless communication
channel
The wireless system requires of use a transmission channel for the
communication of the wireless messages between the various devices.
The best communication channel for the environment in question is
automatically selected by the access point, using the following procedure:
•
power up the access point (the left LED must be on steady);
•
press the button and check the activation sequence:
for around 10 seconds
