GENERAL NETWORK CHARACTERISTICS The “airLINK” family of devices can be used to create a network of sensors and actuators. Such sensors and actuators are able to convey their operating data (input values and status, output settings, parameters, etc.) to a centralizing hub device called Gateway via a wireless network based on radio (RF) link, using an IEEE 802.15.4 compliant protocol (ZigBee, Miwi compatible).
DEVICE ADRESSING An essential prerogative of all “airLINK” devices is that each one must have its own unequivocal address. Each device, except the Router-Bridge and the Repeater devices, have a dip-switch set, which must be set to the address assigned to the unit. The address must be set before the device is annexed to the network, since the DIP switches are read only once, when switching the circuit board ON or after a RESET.
ON again, it will resume functioning on the previously formed network. Creating the network is the first operation to be completed when forming an “airLINK” network and the airGATEWAY is the only device which can complete this operation.
The term "open network" indicates a network to which new devices can be annexed. The term "closed network" indicates that the network cannot accept new devices. The network made up of airLINK devices is a normally closed network, which can only be opened from the airGATEWAY.
LED “C”: Shows the Radio Activity LED C is most of time OFF, indicating that here is no activity in the radio communications channel, but it gives a short flash when a radio message is received or transmitted.
GATHERING SENSOR / ACTUATOR DATA All sensor/actuator devices in an “airLINK” network send radio messages to airGATEWAY, with full description of their status at regular and programmable intervals. In response to this message, the GATEWAY sends a message indicating the actions to be performed or any variations to be made to their parameters.
14 BASIC NOTIONS ON THE RADIO NETWORK From the radio point of view, the “airLINK” family devices make up a network built on the ZigBee standard from which it inherits its structure and properties. ZigBee is a proprietary-type network. For this reason the devices in this network cannot interoperate with other ZigBee devices produced by different manufacturers.
15 LIMITATIONS IN THE NUMBER OF DEVICES In its minimal extension, the “airLINK” network is composed of one Gateway and one Router or one End- device. To determine the maximum network extension, that is the maximum number of nodes that can be used in...
