By Peter Giling

A straight forward connection between the RS232 and the EDiTS / Märklin booster.
* Now the good old EDITS Booster is to be rehabilitated with Rocrail DDX.
This board is a D.I.Y. project. No boards available.

Features

  • computer electrical isolated from your railroad equipment
  • short cut detection circuit
  • no extra power supply needed


The final disign does look different from this picture!

Remarks

In schematics there are two connectors.

J1 is RS232 connector to PC.

J2 is connector to Edits booster

Pin 2 Pin 4 signal
Pin 3 Pin 2 ground
