Sidetone
•
The sidetone level is available on the line output of controlled transceiver during
transmission.
•
The sidetone level is adjustable through the configuration mode.
Emergency Operation
•
If the power supply voltage falls below 18 V, the RCU6512 stops operating.
•
If power supply falls below 9.0 V, the device automatically powers off.
Configuration Mode
•
Configuration of diverse parameters is made in the "Configuration Mode".
Installation Mode
•
This mode is password-protected and for use by authorized maintenance organizations
during aircraft service on ground only.
Interface
•
The RCU6512 has a RS422 interface for communication with the transceiver.
•
This RS422 interface can receive and transmit serial asynchronous data.
Built-In Tests (BIT)
The RCU6512 has advanced Built-In-Test. It monitors most of internal circuits against failures. The
Built-In Tests (BIT) monitors some external (installation) conditions to increase the reliability of
RCU6512 and RT6512.
Types of BIT:
•
Power-On Built-In Test (PBIT)
starts after Power ON the RCU6512 and RT6512 system.
•
Initiated Built-In Test (IBIT),
on-request test of remote transceiver initiated by special command through serial protocol.
•
Continuous Built-In Test (CBIT)
which continuously examines controller and transceiver operation.
