  • ESU Decoder Hook-up

    I recently purchased a ESU LokSound Select Direct #73700 decoder. This is the Athearn, Atlas replacement type decoder. The wiring diagram printed on the back of the package is pretty clear for motor hook-up and such. However, there are 4 solder pads marked "Output Aux 1, 2, 3, and 4" and also 2 pads marked "Common (+ pole)". I am wondering what would or could these extra pads be used for? I plan to install this decoder in an Athearn Genesis F3 and this is my first ESU decoder. And yes, vendor has loaded all sound info. Thanks....John

    Being as it is an F3, you could use those Aux outputs for number board lights, and classification lights. Even interior cab lights or mars light. To old to have ditch lighting.

      The COMMON is the same as the BLUE wire on decoders with wires. The 4 outputs allow you to have 4 distinct outputs for lighting as you choose. You would have to look in the documentation about resistors for your lights, I've never used a drop in ESU board so am not sure. I do use resistors for the LED lights that I use.

        Thanks for the replies. The ESU website is a little tricky to navigate and the wiring diagram on the package did not expand on these other pads. I'll be getting into the decoder install later this evening. Still need a speaker and I think I may go with ESU "sugar cube". I watched a video on one of the "on line" railroad magazines showing this speaker install in another diesel unit and it sounded great, even on the video. I'll try to post some photos of the final product. By the way, the lighting on the F unit photo you posted looks pretty neat.

          Looking forward to your finished project John.

          As you know, The Select Direct was designed with built in resistors for LEDs to fit as a DIRECT replacement for many modern lighting boards including Athearn Genesis, Atlas, Bowser-Stewart, and Intermountain. They also have solder bridges to bypass the resistors in case you are using bulbs. Each LokSound Select include 6 outputs with 0.25A current each that can be allocated individually to a light effect, which simulates the light patterns of many popular warning beacons. Here is a wiring diagram if you need it.

            i've used half a dozen 'sugar cube' speakers and no pun intended, well slightly, they are SWEET. ESU's is nice as is the sugar cube from Litchfield Station. I bought several early on and made my own baffles with styrene as well as 1/32 basswood. ESU and Litchfield's have baffles. You must use some sort of baffle or the sound is terrible. If you make your own be sure it is well sealed.

              Thanks Louis and Karl. The sugar cube speaker I am going to order is a relatively new item, ESU #50321. It comes with a stackable enclosure and can be doubled up if you prefer. This is my first experience with ESU but it seems they are getting a lot of excellent reviews on ease of use, sound quality and motor control. Like Louis said, the resisters for LEDs are built in...pretty neat.
