Introduction

SourceCon™ Bluetooth receiver module

The BMP40 is a professional Bluetooth receiver module featuring SourceCon™ modular
technology. This unique technology guarantees true plug & play implementation to any
compatible device. When inserted to a supporting slot, the module is instantly installed,
discovered and ready for operation without requiring any additional internal wiring or
complex configuration.

The BMP40 receiver offers wireless connection possibilities for audio playback from
any Bluetooth compatible portable device including laptops, smartphones, tablets or
any other. A long range transmission distance (up to 30 meters) is possible depending
on the installed environment. Device discovery and pairing protection with a storage up
to 8 authorized devices shall prevent playback from unauthorized users in public area’s.

All media information such as track and artist information can be retrieved from the
BMP40 (if supported by the connected device, more info on P15: technical specifications),
while playback control is possible from the connected device or remote control.

The antenna input is implemented by an SMA-type (50 Ω) connector on its panel,
allowing connection of the included (2 dBi) antenna while extension is possible in
situations where its installed in a closed / shielded cabinet. The balanced stereo line
output is connected through two 3-pin terminal block connections.

Overview BMP40

The BMP40 is a SourceCon™ compatible module featuring an (internal) board-edge
connector which carries all signals for getting it connected to any supporting main unit.

All external in & output connections shall be made using the available connectors on
the panel.

1) Balanced stereo line output:

The balanced stereo line output is implemented using two 3-pin terminal block
connectors. The audio output available on this connector allows it to be fed to any
amplifier or pre-amplifier.

2) SMA-type antenna connection:

The antenna (input) connection is implemented using an SMA-type (male) connector
whereto the supplied antenna should get connected. Depending of the installation
conditions (e.g. when installed in a closed / shielded cabinet), it can be extended using
optional available accessories for optimal reception conditions.

Chapter 3

Using the BMP40

Since the BMP40 is a SourceCon™ module, it can be combined with a variation of
supporting main units. The operation and configuration interface might be different of
the unit where installed, however the offered functionality is identical. Some devices
will support control and configuration through a front panel graphical control interface
on a display, while others are also supporting web-control.

This manual describes the control configuration possibilities using front panel control. For
applications where more control possibilities are offered, check the instruction manual
of the used main device for more instructions.

Module screen

Connecting:

The main module screen of the BMP40 indicates
the connection status of the receiver. To avoid
audio playback by unauthorized users in public
installations, transmitter and receiver pairing
is required when connecing for the first time.

Bluetooth receiver

Discoverable for 60s

When transmitter and receiver haven’t been
paired before, the receiver won’t be discoverable from the transmitting device. For

making it discoverable, press the button. Subsequently, the receiver is discoverable
and allows connection for about 60 seconds from any transmitting device.

Once connected, the main module screen displays the name for the connected device
and it will become undiscoverable for other devices.

Once both transmitter and receiver have been
paired, the receiver will remain connectable
for that particular transmitter, even when the

connection button hasn’t been pressed.
The BMP40 memory stores up to 8 authorized
device ID’s.

Installing the BMP40

CAUTION

Before installing the BMP40 to any SourceCon™ compatible device,
make sure the power is switched off. Malfunctions or electrical shocks
may occur otherwise.

Step 1:

Make sure that the slot whereto the module should be installed is open and ready for
installation. Depending of the main unit, some module slots will be covered by blind
panels when delivered. The corresponding blind panels should be removed by releasing
the screws on both ends.

Step 2:

Before removing the modules from their protective bag, we recommend touching a
grounded metal chassis (or any other grounded point) to prevent electrostatic discharges
affecting the sensitive electronic components. It is recommended to always hold the
module card by the metal connection panel and avoid touching of the components on
the circuit board directly.

Step 3:

Align both edges of the module with the guide rails inside the slot and carefully insert
the module into the slot. It should slide into the slot without any considerable resistance
when well positioned into the guide rail.

14

Step 4:

Some resistance might occur when the module’s board edge connector reaches the
connection counterpart on the main board. Gently push the module all the way into the
slot to ensure that the contacts are correctly inserted. The module is well inserted when
its connection panel touches the metal chassis of the main device where inserted to.

Step 5:

Fasten the module into the slot using the included screws. Be aware that damage or
malfunctions may occur if the module is not correctly fastened.

Step 6:

Once the module correctly installed, the system can be powered-on and the module
functionality will be automatically discovered.
