Connection radio receivers DXR1 / DXR2
To manage radio devices series XR (contact XR200, sensors infrared XR152 and XR8, siren XR300,
radiocommands XR20 and DXR4) on this central is installed a module radio
DXR2.
DXR2 is connected directly on the connector CX1 of the circuit Easy-Connect inside of the central unit
that shall ensure the connection to the line RS485- DX bus.
DXR1 connects on the line DX bus like in the figure , and can be placed far away from the central unit
ina position to obtain more coverage for the radio signal of devices of the series XR.
On the central unit anyway it isn’t possible to work more than two transceivers.
For all devices DX bus, it is necessary to assign an unique addresse to the transceiver.
DXR2 it’s already configured with addresse
32
and cannot be modificated . It’s possible to mount only
one DXR2 on the central unit, un eventual second transceiver can be only one DXR1 with addresse
33
.
DXR1 have a dip switch two positions with whichto select ands addresse accepted from the central unit :
-
32
with both dip switch in off;
-
33
with both dip switch 1 in on and 2 in off.
If utilise DXR1 in addiction to a DXR2 it’s
necessary to configurate it only with addresse
33
.
The central unit XR400GSM and
XR800GSM accept only transceiver with
addresse 32 or 33 and doesn’t accept
devices with duplicate addresse .

NOTE:The red LED on the devices DXR1 and DXR2 diplays the reception of a radio signal, while the
green one diplays the transmission towards other devices. In the waiting phase, the red LED flashes to
diplay the proper functioning. Where it occur errors of connections the two LEDS flash alternately while
they flash together when the receivers are not enabled on the central computer.
