RTX 2278 MODULE (BASE)
It is possible to select four different operating frequencies, all
within the 868 MHz band.
The selected operating frequency must be set in the same
manner on either the memorised RTX2278 (Base) or the RTX
2252 (Sensor) devices.
Use Dip Switch SW1 on both the RTX 2278 and RTX 2252
devices to make the selection.

Description of Operation
The RTX 2278 (Base) device controls one, or at most, two
RTX 2252 (Sensor) devices, through radio-frequency, for the
connection of sensitive edges. It is possible to view two
menus with the RTX 2278 (Base) Device:
MONITOR MENU
PROGRAMMING MENU
With the MONITOR MENU and an acoustic signal (Buzzer),
the Device reports the following information:
A
:
LARM SIGNAL
Led on + Acoustic signal.
This lets you know which one of the memorised RTX 2252
devices the alarm refers to. A short Beep sounds every time a
reference Led lights up.

This lets you know which one of the memorised RTX 2252
devices has low batteries. In addition to the acoustic signal
whenever a reference Led lights up, two brief Beeps also
sound every minute.

Check the Preselected Operating Frequency
Before programming the transmission code for RTX 2252
(Sensor) Transceivers combined with a RTX 2278 (Base)
Transceiver, it is necessary to select one of the four available
frequencies (see the "Operating Frequency Selection"
paragraph). It is then advisable to make sure that the
D
preselected band is free (not already in use by another
device). To carry out this check, do the following: using the
SET key, move to the PROGRAMMING MENU; the Base
5Vdc
scans the preselected frequency and if it is already occupied
25 mA
by the Base the MONITOR LED and PROGR. MENU LEDs
will flash alternately. In this case proceed to select a different
2
frequency (on both the Base and Sensor). If, on the other

programming the Sensors associated with each channel, as
described below.
Programming Keys and Signal Leds
The SEL key: this selects the type of function to be
memorised, the selection is indicated by a flashing LED.
Repeatedly press the key to select the desired function. The
selection will remain active for 15 seconds indicated by a
flashing LED, after which time the device will return to its
original state.
SET Key:
- this is used to choose between the Monitor Menu and the
Programming Menu: if the SEL and SET keys are not used,
the Monitor Menu will be automatically selected after 1 minute
of inactivity.
- this programs the function selected using the SEL key.
Signal Led
Led on: option memorised.
Led off: option not memorised.
Flashing led: selected option.

Programming for the transmission code of Transceiver RTX
2252 (Sensor) no. 1 combined with a RTX 2278 (Base)
Transceiver must be carried out as follows: press the SEL
key, the SENSOR 1 CODE LED will start flashing; in this
phase the Base communicates in broadcast mode with all
installed sensors, looking for one that can be memorised:
press the SET key for the Sensor you wish to memorise to
send the memorisation confirmation code ( the TX LED of the
Sensor will flash quickly 5 times); the SENSOR 1 CODE LED
will stay on steady and programming is finished. The Base
device exits programming if no confirmation code is received
within 15 seconds.
Deletion: The memorised code can be deleted as
follows: press the SEL key, the SENSOR 1 CODE LED
will start flashing. Press the SET key, the SENSOR 1
CODE LED will switch off, and the procedure is
finished.
