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
|PCBoard + parts placement|
|The bill of materials|
|N.B. Self made pc-boards are not supported!|
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|
