Hey All,

I just installed my RailPro system in an Athearn RTR SW1500 switcher locomotive. Damn, it's tight in there! I shoe-horned the LM-3S-21 module onto the factory motherboard and also installed a speaker with some modification to the chassis.

Has anyone installed a LM-3S-21 but removed the factory motherboard to save space? I assume there are resistors on the motherboard for the LEDs so by removing it I would have to install my own resistors? Is there anything else I would lose?

Just wondering if anyone has removed the factory motherboard or if that is a practical solution.

Thanks,

Rob S.

I'm hoping there is a fix for this.

I'm running Railpro Assistant AND HC Simulator on my Linux box (Thanks to G8B4Life) and have an issue with Railpro Assistant. I can get it to connect to the server (usually on the first try) but after the first file is installed, it loses connection. I then have to restart my computer to get it to work again. This also happened when my box was Windows so I don't think the OS is the issue.

Has anybody else experienced this? Is there a fix? Or a workaround?

Thanks in Advance,

Open your RailPro Assistant program and look.

Hey all,

Anyone know if there has been a software update for the LM-3S-21? My Rev is 1.00.

Thanks,

...I'd like to keep the Incand. Bulbs at first, easy to change out later, assume they will work at 5v from what I understand is the voltage putout of the modules.
Question is .... is this a fact? Incand will work? , no resistors needed ? or just bite bullet and do LEDs ?

This is incorrect. The output of the LM-3S outputs is slightly less than track voltage, so almost 14v. I don't know what rating of the bulbs used in P2K locomotives was but if they are 12v then your likely fine (just turn the brightness down to essentially lower the output voltage). If the bulbs are 1.5 or 3v etc then you'll need to appropriately lower the voltage with external components, or just replace with LEDs and resistors anyway..
