one of cap 1 mFd /16v, which will be grounded reverse polarity ( +ve of cap grounded and -ve of cap connected pin no 7 , pls look any rs 232 converter circuit as u know they are all know to every body) This has to be done in this way because the RS232 chip also generates a negative auxiliary voltage. To decouple this negative voltage you need a cap with the plus pole connected to GND and the minus pole connected to this negative auxiliary volatge. Yes, this might look strange to you, even reversely connected, but it is not. Everything ok! Kai Klaas |

| why it has to done in that way? | 01/01/70 00:00 | |
| All capacitors are correctly oriented! | 01/01/70 00:00 | |

| It shouldn't look strange for a moment! | 01/01/70 00:00 | |
