Designed to replace the DCC decoder in Intermountain and Bowser diesel locomotives, it fits the Intermountain ES44 and Bowser S12, as well as many other locomotives. You may need to compare it with the original decoder due to similar - looking Intermountain/Bowser frames. It features a KA2 Keep Alive® for smooth operation on tricky tracks. Pair it with a WOW121 for top - notch sound and uninterrupted performance. Note: This product needs a decoder (like EU621 or WOW121) to work.

Using this IB - MB1 - NC motherboard is easy. First, you'll need to get a decoder like the EU621 or WOW121 because the motherboard won't work without it. Carefully remove the old DCC decoder from your Intermountain or Bowser diesel locomotive. Then, install the new motherboard in its place. Make sure it fits properly and all connections are secure. When using it, the KA2 Keep Alive® will help the locomotive run smoothly even on troublesome tracks. For the best sound experience, pair it with a WOW121. As for maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or moisture. If you have any issues with the fit, compare it with the original decoder as there are some similar - looking frames.
