Here I have faced recently such problem! It appears for phones of a new lineup of phones Benq – Siemens a cable in shops at us practically are not delivered, and if and is, poor quality or without possibility of an insertion and patching phones! I once have occasionally got in the market a cable for S68, EL71 and to it to similar models. My cable long and tiresomely rolled without business and here its hour has come! One my acquaintance has got to itself S68. In a place with it, it has also a cable, fondly thinking, that it can change an insertion, to patch etc. Yes not here that was! The cable at connection in bodies simply with peak cut down it. At detailed survey of a cable it has been established, that at it on connector all that 5 pins! Having rummaged in a world web, I have found out, that this problem has faced not only my acquaintance and I! We have found and pinout a cable. It has appeared what be involved should at least 3; 4; 5; 6 pin. There are cables in which it is involved also 7 pin. On the pinout it looks so: 3 pin – Тх, 4 pin – Rx, 5 and 6 pin – the earth, 7 pin +5 volt for additional charge. Not long thinking we took my cable bought by chance and unsoldered from it connector. This cable was analogue widely known DCA 540 – without a microcircuit. Then my distressful cable has gone to business on chipset PL2303. Knowing where on it of an exit of the earth, reception and transfer and as where gymnastics I took a soldering iron in hands and has soldered a conclusion to corresponding pins on connector that is 3 pin – Тх, 4 pin – Rx, 5 and 6 pins – the earth, 7 pin +5. I will remind, that my cable on PL2303 has been finished, that is resistors on 10 clods for pressure removal are soldered. On cables for 55 series, which my copy on conclusions Rx is also and Tx moves on 5 volt, for 65 – 75 series are necessary 3 volts. Here for these purposes also finish a cable. At first experiment with припайкой only 3 has been made; 4; 5 and 6 pin. Phone perfectly worked, the cable was defined as DCA 100. Then we have soldered and 7 pin, have connected a cable to phone and have checked up on presence of additional charge from USB! The gymnastics went; phone received a food for additional charge. Here so in the presence of a cable on PL2303 and connector from a cable for S68 by us for 40 minutes the high-grade cable for S68 has been collected. The given cable will work and on other models from Benq – Siemens. The variant of manufacturing of a cable and on microcircuit CP2101 is possible. The driver naturally, in this case we use for a cable on chip CP2101. At assemblage on PL2303 were established and corresponding the driver!
