I have both versions of SatStat (the HP and the Symmetricon). Both are set for COM1 9660, 8, n, 1. Both are running in an XP VM. I have tested the virtualized to physical COM1 connection using a terminal program and a scope, so I know that works. When I select Port Open, I just get "Trying to establish communication". I never see the SatStat info page.
If I use the terminal program under XP or on the Win7 host, I can send *IDN? , :SYST:STAT? etc. but never get a response. Although I can see a response by scoping the cable - it peaks around 4.5v, and is quite noisy. My suspicion is that it's the noise that is causing the trouble. AECI are sending me replacement units, but if you have any ideas of other things to try, let me know Thanks ANthony -----Original Message----- From: time-nuts [mailto:time-nuts-boun...@febo.com] On Behalf Of GandalfG8--- via time-nuts Sent: Friday, November 07, 2014 2:11 PM To: time-nuts@febo.com Subject: Re: [time-nuts] Lucent KS-24361 GPSDO arrived today several questions When you say, all of that is what you see........... Do you mean you go through the SatStat start sequence and you see the SatStat info page? If so what happens then, or does it in fact stop earlier than that?

As I said, I can send data to the boxes from a terminal program and see it coming back by scoping the line. I may return the units and get a different pair. It just seems odd that both units behave in this way. -----Original Message----- From: time-nuts [mailto:time-nuts-boun...@febo.com] On Behalf Of GandalfG8--- via time-nuts Sent: Friday, November 07, 2014 11:39 AM To: time-nuts@febo.com Subject: Re: [time-nuts] Lucent KS-24361 GPSDO arrived today several questions Hi Anthony, Are you sure you've got the COM port set up correctly? Should be 9600 baud, 8 data bits, 1 stop bit, No parity, No flow control In SatStat, for example, you should get a message on startup that says.... To Start: Select port Open on the CommPort Menu... If you do this, assuming the correct settings, it should bring up a message.... Communication Established, Please Wait Then the SatStat Info page should open. This is with the Symmetricom Windows version of SatStat, version 5, do you see any of this when you try to start it?

I received an RS422 to USB cable and also an RS422 to RS232 convertor but neither of them has given me any success, on either box. I can see data coming out of the port on my scope, on top of a noisy 1.2V line, but cannot get a terminal program, SatStat or Z38XX to display anything. It's crazy.

For what ever reason (yes one could guess ? ) I stayed focused on finding a 3810/11/12 manual rather than dropping back to the 3801 manual. Now the question becomes that magic 10 pin header on the board. If it ??s jumpers (might not be) one of them could enable bi-directional communication. Thanks for checking this to see that it works on at least one other box.
