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
that can be used with BSM-2.

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
A
100 Ohm
D
100 Ohm
B
270 Ohm
E
270 Ohm
C
400 Ohm
F
400 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.
