BRAVO Telemetry Module
DS-BRAVO-9
BRAVO Configured as a TRANSMITTER
1.
Operation
When configured as a transmitter the BRAVO module will automatically default to low power
sleep mode until any input state change takes place.
On receipt of an input state change the BRAVO-Tx will transmit a packet showing the state of
changed input/s (multiple input changes may take place simultaneously)
1.1 Watchdog
If watchdog is enabled the Bravo-Tx will transmit a background packet containing the current
status of the inputs every 5 minutes.
1.2 Digital Inputs
High impedance inputs, LVCMOS / LVTTL compatible, 5V tolerant.
Can be connected directly to CMOS/TTL logic or switch inputs connected to 0V or VCC
A change on the input will cause the BRAVO-Tx to wake, read all inputs and initiate RF
transmission.
Description:
This example shows a BRAVO module
configured as a transmitter with all 8 inputs connected and watchdog disabled.
Notes:
All input switches would need to be connected to GND to activate.
