Yes. It does not prevent the lockup (lockout?) As I said in an earlier post, the 3478A is not giving any indication that it is addressed, or connected to the bus at all. It *always* does when the HP85B is connected as the controller. > This setting is persistent, so you should only have to do it once to keep > the board from automatically addressing the 3478A to talk. > > Also try disconnecting any/all other RS-232 devices from your PC during > initial testing, and/or try a different USB port. The port is the only one the laptop has, and it works just fine. The laptop is running kermit under linux, so it is a very basic connection. The problem is clearly entirely within my Prologix. I cannot yet say whether it is a bug in the firmware, a circuit failure, or a design flaw. The 3478A, and the cables used work just fine with an HP85B. -Chuck Harris _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
