Herbert Thanks for the assembly listing. Someone else on time-nuts had done quite the job of reverse engineering the schematics and other information. Seems like the two of you could collaborate. Sorry do not recall the name. Welcome to time-nuts. Regards Paul WB8TSL ------------------------ Was just thinking the same thing so checked through my archives. That was Elio, [email protected]_ (mailto:[email protected]) , messages posted here about a year ago. The messages will be in the list archives anyway but below is the text of two messages I saved. Regards Nigel GM8PZR ---------------------------------------------- From: [email protected] Reply-to: [email protected] To: [email protected] Sent: 15/02/2012 01:31:32 GMT Standard Time Subj: [time-nuts] FE-5680A Schematics (v0.1) at the following address: < http://www.rhodiatoce.com/pics/time-nuts/FE-5680A/FE-5680A_schematics_v0.1.p df > 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. _____________ ------------------------------------ From: [email protected] Reply-to: [email protected] To: [email protected] Sent: 24/02/2012 01:03:56 GMT Standard Time Subj: [time-nuts] FE-5680A Schematics and scans Thanks to Ignacio (EB4APL) and the generosity of Mike Harrison, today I received a PCB of a disassembled FE5680A.
