The Schneiderware V/24 Interface is a RS232 Interface, published by german magazine CPC Schneider International as part of their Schneiderware DIY series. The plain PCB, or the fully assembled board were also available via mail-order.
The ECB Bus connector of the board is intended to be plugged into the Schneiderware Basisplatine, but it could be also wired directly to the CPCs Expansion Port. The V/24 board additionally requires a Schneiderware Power Supply (or another external power supply with +12V/-12V).
