Description
Antenna input/output 50ohm impedance
Connect to ground
Active High
Digital outputs: LVCMOS output drive
Learn switch input: Normally ‘high’ momentary connect to Ground to enter Learn Mode.
If on board switch or to be used this input can be left
unconnected.
Optional LED drive output mirrors on-board LED
Connect to GND : Module is configured as a receiver
High : Watchdog is healthy
Low : Watchdog Fault!
Only used when transmitter has a watchdog function enabled.
Supply voltage
Leave unconnected
Set outputs to Momentary or Latching operation.
Low: All outputs momentary
High: All outputs latching
1.1 General description of operation
A remote control system is achieved when a BRAVO module is paired with a transmitter. You must configure the outputs to momentary or latching. If momentary the output will action ON while an associated
handset button is held ON. If latching the outputs shall toggle with each press-release of an associate
button.
NOTE: All outputs “auto-map” when a transmitter is paired to a receiver all outputs will automatically maps
to the relevant numbered inputs. Ie button to output 1 and so on.
NOTE: BRAVO can do MORE! It is possible to make a system with two of more BRAVO modules - see the DS
-BRAVO for more details.

2. BRAVO Configured as a receiver
2.1 Watchdog enabled
If “watchdog” is enabled the BRAVO will await a signal from a paired transmitter/handset. The transmitter will send a watchdog signal periodically, when this Watchdog signal is received at regular intervals the watchdog output will be maintained active high.
If no watchdog signal is received in any 30minute period then the BRAVO
will drop the Watchdog output.
NOTE: No current handsets support the WATCHDOG feature - mainly for use with another BRAVO
module configured as a receiver - see website for details.
2.2 Digital outputs
Active high LVCMOS / LVTTL compatible outputs. Can be connected directly to CMOS/TTL logic or
drive.

3. Pairing process - Handset to BRAVO
Each BRAVO module may be pair to one or many handhelds using the LEARN button (or parallel learn input) so that they operate discretely or in systems. The pairing process is simple but requires close attention to be pair to the LED (on board or parallel LED output pin 6).
3.1 Pairing process: LEARN:
1.
Briefly press the “LEARN” switch (or activate LEARN input) on the BRAVO
2.
After you release the learn button, the LEARN LED will flash once
3.
This shows that output 1 is selected.
4.
Press the LEARN button again, after it is released the Learn LED will flash twice,
continue in the same way to select outputs up to 8.
5.
With your chosen output selected, briefly press the button on the handset that you wish
to pair.
6.
The LEARN LED will flash quickly to show that pairing is complete.
7.
Repeat the process to all required pairings
3.2
Paring process: ERASE:
1.
Press and Hold ‘LEARN’ switch (or input) on the BRAVO for more than 10 seconds.
2.
The LEARN LED will start flashing to show that erase is complete
3.
Release the LEARN switch.
Notes:
The maximum number of pairings is 51.
One pairing is counted as a single button - output association
Pairings can be on one or many handsets
4. Compatible handsets
The BRAVO module works with all handsets in the ELITE Series of products. The choice of
will affect the maximum achievable range of operation.
ELITE-T
The ELITE-T is a small low power handset
designed for home use and operating over
a maximum range of 200m.
ELITE-XT
The ELITE-XT is a medium sized handset
designed to fit any application needed long
battery life and long range. The ELITE-XT is
a compact but robust handset operating at
a maximum of 1000m
SABRE-T
The SABRE-T is a rugged industrial handset
with huge range of operation and
waterproofing. The SABRE will work at up
to 2000m.

6. Range considerations
The antenna choice and position directly affects the system range, keep it clear of any large
metal parts . The best position is protruding vertically from the top of the product. This is often
not desirable for practical reasons and thus a compromise may be needed. Note that the space
around the antenna is as important as the antenna itself. All radio systems are dependent on a
radio signal being received through airspace. The range quoted is the optimal in direct line of
sight without obstacles and in good atmospheric conditions.
Range is affected by many things, for example local environmental conditions, atmospheric
conditions, interference from other radio transmitters. For evaluating the local environment
please see our RF Meter (DS006) In very worse case applications the range quoted may be re-
7. Self test mode
The Bravo Module incorporates a self test which is initiated by applying power with the learn
Button being held down. The Bravo Module then performs the following functions;
1.
All I/O are set to outputs and are operated
2.
Outputs roll In a sequence 0 to 8 back 0 again
3.
Outputs operate in a 4 on 4 off sequence
4.
Transmits a full power RF signal for 10 seconds and operates the Learn LED
5.
Enters RSSI (Received signal Strength) mode where outputs 1-8 are activated as a bar
graph type output according to the strength of a valid RF signal received (from any carrier operating at 869.50MHz)
6.
A reset will be required to exit this mode
