General Description
Purpose of Equipment
DV17551.03 Issue 03 June 2020 RCU6512 13
1.2 Purpose of Equipment
The Becker Avionics Remote Control Unit RCU6512 is made to operate with the VHF transceivers of
the RT6512 series.
Primary function of RCU6512 is to be the HMI (Human Machine Interface) for interaction between
users and VHF transceiver.
• The system of RCU6512 and transceiver is for voice communication between aircraft or
between an aircraft and ground stations, using the very high frequency band between
118.000...155.975 MHz (depends on RT6512 variant).
• The RCU6512 is made for installation in the instrument panel of an aircraft.
o The dimensions correspond to the standard for instruments 58 mm (2¼ inch).
• Installation with standard supply 28 VDC or with 24 VDC batteries possible.
• The RCU6512 can operate at emergency voltage 18 V without any degradation of
performance.
• Channel spacing of 25 kHz or 8.33 kHz.
• Non-volatile memory for storing up to 40 frequencies/channels.
• Squelch functionality, ON/ OFF for squelch function of controlled transceiver.
• Data exchange between RCU6512 and VHF transceiver through a RS422 serial interface.
• Different built-in tests examine the correct operation of RCU6512 and transceiver.

General Description
Scope of Functionality
DV17551.03 Issue 03 June 2020 RCU6512 15
1.5 Scope of Functionality
• The RCU6512 is a compact and lightweight device.
• All controls and indicators are on the front panel.
• The equipment connector is at the rear side of the device.
• Installation with four screws (rear panel installation).
The dimensions correspond to the standard instrument diameter of 58 mm (2¼ inch).
Figure 2: RCU6512
Illumination
The illumination of LCD and push buttons can be controlled.
• Direct control from the front panel (through the user menu).
• External control through the dimming input lines.
o With external dimming application the illumination curve (brightness to voltage relation)
is adjustable in configuration setup.
Channel Spacing / Frequency Range
The RCU6512 together with RT6512 is for voice communication between aircraft or between an
aircraft and ground stations using the VHF band between 118.000...155.975 MHz (depends on
RT6512 variant).
• 8.33 kHz channel spacing: from 118.000...136.990 MHz.
• 25 kHz channel spacing: from 118.000...136.975 MHz.
• 25 kHz channel spacing in extended frequency from: 118.000... 136.975...155.975 MHz.
• The RCU6512 operates with all frequency band variants of RT6512 transceiver series.
Memory Channels / Frequency Storage
The RCU is capable to store up to 40 frequencies assigned to channel numbers in two banks.
• 20 memories reserved for 25 kHz channels spacing mode.
• 20 memories reserved for 8.33/25 kHz channel spacing mode.
The word "frequency" also used in the sense of "channel name", as defined in
EUROCAE, document ED-23C chapter 1.3.2.
In this document the word "memory channel" or "channel" means a memory place
identified by a channel number, where a frequency can be stored for later use.
Squelch Operation
• The squelch (muting) circuit suppresses unwanted audio noise.
• RCU6512 can change between ON/ OFF for squelch function of controlled transceiver.
• Squelch threshold is adjustable through the configuration mode.

Scope of Functionality
16 RCU6512 DV17551.03 Issue 03 June 2020
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.
