At the
schematic page IC2 (MAX232) seems to missing pin 15 (Vcc) and 16 (GND), which are shown in the assembly sheet.
Also the marking V+ and V- is slightly confusing (i confused V+ for Vcc). V+ is marked VS+ and V- is marked VS- in the
MAX232 datasheet.

The schematic was drawn using the eagle software package by Cadsoft. This software comes with many libraries of devices. The MAX232 chip available in one of those libraries is drawn like that; without actually showing the Vcc and GND connections. While it is possible to add your own library of devices, it is quite a bit of work. So I just used the existing device.

The linked Conrad component datasheet uses the MAX232 by Texas Instruments, maybe use their Eaglesoft version of the library created by Vitaly Luban from Conexant, which could be found
here?
