| 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.
