 We don't provide a case for the PCB - this is left as an exercise for the reader (some, less fussy, readers simply wrap the entire PCB with insulating tape). We don't provide a case for the PCB - this is left as an exercise for the reader (some, less fussy, readers simply wrap the entire PCB with insulating tape).

-{{:​livebox:​cimg1759.jpg?​320 }} Making an RS232 adaptor. Crimped up a RJ11 6P6C onto a piece of cat5 cable. Repurposed a PCB which has a Max232 onboard to do the hookup. N.B. The chip needed for this convertor is the MAX3232 - this works at 3.3V (costs rather more than a MAX232 - tried a MAX232, it doesn'​t work). Turns out that the serial port socket on the Livebox isn't a '​standard'​ RJ11 connector - it is a MMJ connector with the retaining clip offset from the centre of the socket - a standard RJ11 needs to have its clip cut off to allow the connector to enter. This gives '​reduced'​ insertion force, but there is a slight resistance - just enough to keep the connector in place. ​+{{:​livebox:​cimg1759.jpg?​320 }} Making an RS232 adaptor.
