ZULU Telemetry

Application Example ONE to ONE

Zulu

Transmitter

Input 1 - 10

Zulu

Receiver

Output 1 - 10

Transmit

Signal

Acknowledge

In this application the outputs at the receiver will track the inputs at the transmitter.

The receiver outputs are acknowledged back to the transmitter.

If required the Watchdog can be enabled to inform the user if the RF system has a fault.
