at the following address: < http://www.rhodiatoce.com/pics/time-nuts/FE-5680A/FE-5680A_schematics_v0.1.pdf > you will find the 0.1 release of the FE-5680A schematics.
New additions: - pinout of the unpopulated (24 pin) connector (J9) behind the DB9 - connections between CPU/MAX3232 and the *TWO* serial ports!!! - component values of the 10MHz filter + option on PCB to output a square 10MHz wave on DB9 - connections between CPU and MAX1246 (A/D converter) - connections between XC9572 and MAX392 (quad analog switch) - unknown pins marked as '?' As you can see, it seems FE-5680A fully supports 2 serial ports: one on DB9 and the other one on the unpopulated connector (J9) behind DB9. Any comments/suggestions are welcome. . ciao _ Elio. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
