The RS-232 Serial Interface Module reads the Phone Sleuth output to your computer. Translates TTL logic levels into standard RS-232 data, suitable for driving a computer's serial port. Additionally, the unit translates RS-232 data from TTL logic levels, should you find that necessary. This kit is remarkably easy to build, using just one Integrated Circuit (the Maxim MAX-232 an RS-232 Driver/Receiver) and a handful of external parts. Very cost effective! Only one RS-232 Interface is needed to read the output of as many Phone Sleuths as you need. |
