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.
3.1
Gateway Addressing (except Ethernet version)
The connected client (PC or PLC), accedes to the network through the GATEWAY address. This allows
the access to the operating data of the GATEWAY itself and to set and manage the radio network
parameters.
The airGATEWAY address can be set-up by means of a set of 3 DIP switches (1 to 3 in the schematics of
Fig. 3-1). DIP4 is not used for assigning the address but for choosing the speed of the serial port.
Valid Gateway addresses are ranging from 1 to 7.
The default configuration is peripheral Nr 1.

Fig. 3-1. airGATEWAY DIP switches set
The DIP switches are read only once, when switching the circuit board ON or after a RESET.
A modification of the DIP switches position is only taken into consideration after a RESET. It
is recommended to set the DIP switches before switching the device ON.
Be careful when assigning Gateway address through a remote link. Setting a wrong address
may cause the loss of the link. In this case the client will be unable to communicate again with
it and therefore will be unable to re-configure it via remote.
For all peripherals, in case that the radio link is established through an
airBRIDGE
, the lower
address allowed is 50 and the maximum is 240.

Speed setup
DIP4 is used to setup the speed of the serial port. (DIP4 : OFF->9600Baud; ON->19200Baud).
