Hi: I opened up my Z3805A and after looking at the bottom of the main board think it's already jumpered for RS-232. See the bottom photo at: http://www.prc68.com/I/Z3805A.html#DB-25 near the DB-25 connector. There's only 3 zero Ohm jumpers and none of them are where the Z3801 jumpers were.
Also is there a way to tell which GPS daughter board I have? See the top side motherboard photo (click for larger, click again if (+) cursor: http://www.prc68.com/I/Z3805A.html#DB-25 The metal can is marked: 326/2486 2643686MAD and the PCB is marked: TM-AB The motherboard has many things that raise questions, like installed parts whose function is not clear, like: 6 LEDs near U1 J2 2x5 0.1" vertical header pins, JTAG? J13 4-pin horizontal connector S1 with 8 switches Many component pads without components. -- Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html _______________________________________________ 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.
