Installation and wiring
Mounting location
Before installing the BSM-2, consider location and cable
runs necessary to connect the module to display unit,
transducer and power source.
The mounting location must allow for required working
area when connecting the cables. Also ensure that the
location allows viewing the unit’s LED indicators.
The units should be mounted with special regard to the
units’ environmental protection, temperature range and
cable length.
The mounting surface needs to be structurally strong,
with as little vibration as possible. If possible mount the
unit close to the edges of a panel to minimize vibration.
Do not run the transducer cabling near the BSM-2 power
cables, any VHF antenna coax cables or any DC or AC
power cables. Avoid placing Ethernet cables close to VHF
antennas.
The BSM-2 conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but proper installation
is required to get best use and performance from
this product. Ensure you have as much separation as
possible between different electrical equipment, (see
diagram below).

Securing BSM-2 module
Mount the BSM-2 on a vertical surface with the power
and transducer cable entries exiting downwards.
Fasten the BSM-2 by using the 4 stainless steel self
tapping screws included with the unit.
Wiring
General
The power and the transducer
cables connect with screw
terminals inside the BSM-2
unit. Refer wiring diagram and
connection details on the following
pages.
The BSM-2 contains high voltages and specialized
parts; the operator should never remove the
module’s cover without removing the power
connection.
Removing the transducer cable from the BSM-2
while the module is powered on can cause sparks.
Remove the transducer cables only after the
module has been disconnected from its power
source.

Power connection
The unit has no power key and will turn on when power
is applied.
When used in an
NSE/NSS system, it
is recommended to
connect the BSM-2 to
the Power control bus,
and set display system
to power control
master.
If the BSM-2 is connected
directly to the vessel’s
battery, the module will
continue to draw power even
when it is not in operation. It
is recommended that the
yellow power cable wire be
fitted with an optional on/off
switch, allowing the BSM-2
to be powered off when not
in use.

Airmar transducers
The wiring diagram below shows how to connect an
Airmar transducer (R309).
On some models Low frequency XDCR+ wire (yellow) can
be color blue/white.
On some transducer models temperature brown cable is
connected internally to XID GND, and there is no need to
connect bare and brown cable together.
Consult XDCR documentation for correct wiring diagram
before connecting transducer!

Strap settings for transducer impedance
Each transducer connector has 3
transducer impedance jumpers, used to
assure max power is being transferred
to the sonar elements.
The transducer list on page 21 shows
how to set the jumper for transducers

For any transducer not included in the list, connect
the jumper to the impedance selector according to the
transducer impedance based on the following table:
HIGH FREQ LOW FREQ
A100 Ohm D100 Ohm
B270 Ohm E270 Ohm
C400 Ohm F400 Ohm
If the Transducer impedance doesn’t appear in the table,
select the closest impedance that is higher than the
customers value.
Connecting the BSM-2 to your display
The BSM-2 connects to your display system over an
Ethernet network, either directly or via a Network
Expansion Port. Refer Cabling diagram, page 9.
When connected to an NSO, the RJ45 to 5 pin cross-over
Ethernet cable included with the NSO system must be
used.
For details refer to the display system’s Installation
manual.

ENGLISH
Setting up the transducers
The BSM-2 is compatible with Airmar’s Transducer ID
protocol. If you have an Airmar transducer that supports
this feature, BSM-2 will read your transducer’s
specification at start-up and automatically adjust the
frequency and temperature settings. The transducer’s
XID wire (orange) should be connected to the XDCR_ID_
HIGH/LOW terminal in the TEMP HIGH/LOW connector as
shown below.

TEMP HIGH GND XDCR ID HIGH

If your transducer doesn’t support Airmar’s Transducer
ID protocol, the transducer selection and configuring
needs to be done from the display as shown on the
graphics below.
A detailed description is found in the relevant
documentation for the display.
