PowerBox Systems PBR-14D Instruction Manual

1. PRODUCT DESCRIPTION

The PowerBox PBR-14D is a highly developed and advanced transmitting and receiving system for RC models, offering unprecedented range in the 2.4 GHz band and ultra-fast, ultra-precise data transfer in both directions. Unlike typical receivers, PowerBox transceivers are capable of transmitting and receiving at the same data rate and range as the transmitter. They feature an integral pre-amplifier contributing to their long range. The PowerBox radio link uses a hopping system across at least 66 of 198 possible channels with an intelligent hopping sequence for interference-free operation. Suffixes like 'D' indicate the number of radio units; 'D' types (e.g., PBR-9D, PBR-26D) incorporate two fully independent receive/transmit units. PowerBox transceivers process data packets in undamped form, performing a full analysis. If one packet has errors or poor signal, data from the other unit is used, ensuring a 100% signal even if one aerial is blocked. As of software version 3.5, supplementary receiving units can be connected via the FastTrack socket. The integrated iGyro system, standard in models like PBR-7S, PBR-9D, PBR-10SL, and PBR-26D, provides control of six separate axes and can be speed-compensated when connected to a GPSIII or PBS-TAV sensor on the P²-BUS. iGyro settings are adjustable via the transmitter's Telemetry menu. PBR receivers can generate various BUS signals (S.BUS, SRXL, analogue PPM) for compatibility with third-party products like helicopter gyros.

3. PRODUCT DIAGRAM AND POWER SUPPLY

The PBR-14D receiver features the following labeled components:

• A blue push-button for electronic switch operation.
• An LED indicator.
• A socket for an external MicroSwitch.
• An MPX high-current socket for power input.
• PWM outputs labeled A1 through N14.
• Two P²-BUS telemetry and servo ports.
• A FastTrack/data connection port.

Power is supplied to the PBR-14D via the MPX high-current socket. An integral electronic switch means no external components are required. The receiver can be switched on/off using the integral blue push-button or a separately available MicroSwitch (#3584) or MicroMag (#3585).

4. BINDING

Transceivers can be bound using two methods:

1. Connect the transceiver first: The LED flashes rapidly for approximately ten seconds. Press "Bind" on the transmitter to bind the transmitter and receiver. If "Bind" is not pressed within ten seconds, the receiver LED will flash at a slower rate, and binding will only be possible after disconnecting and reconnecting the power supply.
2. Press "Bind" at the transmitter first: After this, connect the receiver to a power supply to complete the binding process.

5. DETAILED DESCRIPTION OF THE SOCKETS

a) PWM outputs

The PWM outputs are sequentially numbered from 1 to XX and also assigned letters A through I. Optionally, receiver outputs can be configured to generate different channel numbers. For example, the PBR-9D can generate outputs 10-19 as well as channels 1-9.

b) P²-BUS

This interface is used for the external ultra-fast P²-BUS telemetry system and digital servo output. When the system is powered on, all connected sensors are scanned and displayed on the transmitter. The P²-BUS socket can also be used for updating the receiver via a USB interface adapter.

c) FastTrack/Data

This socket is configurable via the transmitter for various functions, including FastTrack, P2BusOUT, S.BUS, SRXL-16, PPM12, or an additional servo output.

• FastTrack: Connects the iGyro SAT or a supplementary satellite receiver (PBR-26XS). FastTrack is a high-speed real-time bus system. Both the iGyro SAT and a satellite receiver can be connected simultaneously using a Y-lead. An iGyro SAT provides full six-axis iGyro system control adjustable from the transmitter.
• P2BusOUT: Feeds telemetry data wirelessly from the model to ground stations, commonly used in events like Triangle flying. The receiver monitors radio traffic between the transmitter and receiver in the model, relaying telemetry information to the connected ground station.
• PWM: Allows connection of an additional servo to the FastTrack/Data socket. The generated channel varies by receiver type; for the PBR-14D, channel 15 is available.
• S.BUS and SRXL-16: These digital bus signals are compatible with many gyros and battery backers, serving as a universal interface for third-party accessories such as helicopter gyros.
• PPM12: As of version V3.5, all receivers can generate an analogue PPM12 signal, useful for wireless connections to PC flight simulators.

6. MEANING OF THE LED DISPLAY

The integral LED indicates various receiver statuses:

• Continuous blue light: Transceiver is bound to the transmitter; signal strength is adequate.
• Flashing rapidly blue: Transceiver is waiting for a binding signal.
• Flashing slowly red: Receiver is picking up no signal.
• Continuous red light: Update has failed, and the receiver is in bootloader mode. Use the Rescue mode to restart the update process.

7. INSTALLATION, DEPLOYING THE AERIALS

PowerBox receivers are manufactured using the SMT method, offering high resistance to vibration and shock. The PBR-14D is ideally mounted using the supplied retaining plate or secured with double-sided adhesive tape. Aerial deployment should be optimized for the specific model, fuselage material, and receiver position. Routing aerials out of the fuselage is recommended for optimum reception regardless of model materials.

8. OTHER SETTINGS

Transceivers offer optional settings configurable via the transmitter:

• Frame rate: Defines the servo signal repeat frequency. The default is 18ms; modern digital servos perform more accurately and smoothly at 12ms.
• A Start output: Offsets the Start channel, enabling receiver cascading. For instance, a PBR-14D can generate channels 1-14, with an additional PBR-7S handling channels 15-21.
• Hold/Failsafe: This setting is adjusted in the transmitter's Function menu, not on the receiver.
• iGyro: Detailed iGyro features are described in the iGyro SAT instructions. The integrated iGyro function is identical to that in larger PowerBox systems or the iGyro3xtra.

9. NOTES ON OPERATION

PowerBox transceivers transmit battery voltage and reception quality by default:

• Battery voltage: Displays the voltage at the servo sockets. Note that if a regulated battery backer is used, this value represents the regulated voltage, not the raw battery voltage.
• RSSI: Indicates the input level at the aerial, displayed in dBm (a logarithmic power value).
• LQI (Link Quality Indicator): Shows reception quality as a percentage, calculated based on lost data packets and power level over time. Monitoring LQI with an alarm threshold (e.g., 60-70%) is recommended to immediately identify reception issues. Version 3.5 offers an additional LQI calculation considering both aerials, focusing on data packets lost simultaneously on both.
• Status: Displays status messages for connected devices like iGyro SAT or GPSIII.
