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
A 100 Ohm
B 270 Ohm
C 400 Ohm
LoW FrEQ
D 100 Ohm
E 270 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.

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.

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.
