    Thank you for posting this! I was considering to modify my Roco V200 with Kuhn decoder – and now I will 🙂

    Here’s a good link to calculate the resistor value once you’ve selected the LED and got its specs:

    • Hi again, are you for sure certain Kuhn supports capacitors and/or extra outputs on SUSI? If so don’t hesitate to confirm (which models for example), I’ll be glad to add it to the article.
      I’ve never used Kuhn but I know they are quite popular in Benelux/DE/AT.

        Actually besides the SUSI ports, the Kuhn 45 has two extra amplified ports, ‘Function C’ and ‘Function D’. So I was planning to use those.

        The SUSI can be either configured as SUSI or as Function ‘E’ and ‘F’ (the default for CV56 where it’s configured) but they are not amplified. Not sure how much power draw those will allow.

        • Yep, Function C and D for Kuehn are called AUX1 & AUX2 by Doehler & Haass (Zimo probably has another name). Those are regular amplified outputs indeed.
          But for my V100 for example I needed 5 outputs total, so I used 4 amplified + 1 SUSI (driver cabin).
          The Kuehn manual just says the SUSI outputs (if used as such, and not for a sound module) are “logic”. That usually means the same thing: 5V (the SUSI standard anyway), and likely 15 to 20mA loads max.
