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.
- computer electrical isolated from your railroad equipment
- short cut detection circuit
- no extra power supply needed
In schematics there are two connectors.
J1 is RS232 connector to PC.
J2 is connector to Edits booster
Because connector type is different, the following table gives conversion.
|GCA98 J2||Edits Booster K1||Function|
|Pin 1||Pin 3||+ 20 Volt|
|Pin 2||Pin 4||signal|
|Pin 3||Pin 2||ground|
|Pin 4||Pin 5||Short circ.|
|Pin 5||Pin 1||-20 Volt|
