DIACOM cable and SBEC scantool.

[Oleg Gusev]

Hi guys,

 concerning the hardware for data acquisition. The schematic
 at www.coil.com seems to be a huge overkill for that task.
 It might be useful only to those having warez copies of
 DIACOM itself. I was laughing to death after i read about
 finding 1/2 Watt 2.67K resistors for these simple
 transistor switches. Busy looping on PIC timer for
 async emulation is also no fun, and forces to use DOS.
 Anyway, it is much easier to use
 TTL->RS232 converter or to modify the old serial ISA
 card with 16450 + 1488/1489, replacing 1488/1489 with
 TTL invertors. It can be used also for other useful projects
 ( communication with Nokia/Ericsson GSM cellular telephones,
 for example ).
 Hopefully i'll do that some time soon.
 
    Oleg.
