BRAVO Telemetry Module
DS-BRAVO-9
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 condi-
tions, 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 reduced dramatically below
the optimal range stated.

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.
in a traffic light sequence 0 to 8 to 0 again.
3.
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 car-
rier operating at the appropriate frequency (869.50MHz or 915MHz)
6.
A Reset will be required to Exit
