Default Airmar TM150 wiring into a BSM-2/ NSE 12

Ok guys, we finally got a sea trial on the boat last weekend and since we were up until 1 am mounting the transducer after full days of work for all of us, the set up did not work.

We got the BSM to be found via the NSE however I do not think the BSM recognized the TM 150, we were able to get a reading however the depth was just stuck on zero the whole time and no matter what setting we messed with we just didnt have any luck.

We still have to remove the leaning post and replace all the fuel lines after work tomorrow and if possible we would like to get out on the water early saturday again so I thought Id post this up and see if yall could tell us how this is supposed to be wired in.

For the record I think its ridiculous that each wire has to be separated and manually inserted into the unit.

The first picture can be used to depict what the circuit board is labeled on the sounder.

The second can be used to (kind of) see the wire colors. If i recall there is an orange, brown, purple,black, blue,white and a bare wire.

The third picture is how the unit looked when we first opened it (used unit), aka what the prior owner possibly had hooked up.

The reason why BSM-2 comes with screw terminals is because all CHIRP transducers previously where delivered without connectors, the current model BSM-3 comes with connectors. Professional installers and advanced users like me consider screw terminals as a good solution. BSM-2 came with a pigtail adapter (TA BSM-2) to be used when connecting transducers with Blue connector.

You need to connect the XID signal for the transducer to be recognized. It should be connected to the High (J5) terminal block. You can see the colors on the short wire stubs on your images. The purple wire should not be used.

Reading the installation manual would also be a good idea.
