[time-nuts] Z38XX Pre-Modified for Z3811A and Z3812A
I was playing around with my Lucent KS-24361 gadget boxes this evening and after toying and fiddling around with the Z38XX software I thought I would make the following available to other time-nuts: From the readme.txt file content I posted on the link below... where you can download a version of Z38XX that has been pre-modified to work with either the Z3811A or the Z3812A Keep reading if you want to try it / download it. Max NG7M (my slopped together readme.txt file) This is a modified version of Z38XX brought to you by the late Ulrich Bangert. (it's very clear that many time-nuts hold Ulrich in high regard and I wanted to make sure and mention his work here) His website is no longer available so I thought I would host the modified version on my web server: http://www.nc7j.com/downloads/NG7M/Time-Nuts/Z38XX-Modified-for-Lucent-Z3811A-Z3812A/ The zip file in this directory contains simple mod to the original version to allow it to talk to the Lucent KS-24361, HP/Symmetricom Z3809A, Z3810A, Z3811A, Z3812A GPSDO. The original exe is also included in the zip file. The mod is simple, via a hex editor (as reported by Götz Romahn) is to change the strings used for comparison at start up when Z38XX asks for the version. i.e. just modify the strings in the exe binary without disrupting the string table space. In a hex editor you search for Z3805 and replace it with Z3811 for the RFTG-u REF 1 box. Since I'm lazy and I really couldn't tell a difference if you use the Z3805 or the Z3815 command set in Z38XX, I also did a search and replace on Z3815 and changed it to Z3812. This allows you to use the same Z38XX version for either the Z3812A RFTG-u REF 0 box or the Z3811A RFTG-u REF 1 box. When connected to either J8-DIAGNOSTIC port. On another note, I couldn't get a PCI-Express 4 port serial card to work with the simple RS-422 to RS-232 cable hack. However, I had success with a good FTDI based USB serial adapter. In this case, it's a real FTDI chipset. Your mileage may vary as I have seen others scratch their head over problems getting the 422 / 232 cable hack to work. Anyway, I hope someone can find the 'pre hacked' version of Z38XX useful. Enjoy! de Max NG7M -- M.

Re: [time-nuts] Z38XX Ulrichs program question How do you restart thegraphs.
Paul, I don't know for certain but with the limited playing around I have done with this program, I would start by renaming the data file and then let the program restart a new file from which I assume the graphs are plotted. I forget the file name off hand, might be something .dat or similar. It is a simple text file. cheers, Graham ve3gtc On 12/8/2014, paul swed paulsw...@gmail.com wrote: Boy I have dug through the program and can not seem to find a way to clear out the graphs.

Re: [time-nuts] Z38XX Ulrichs program question How do you restart the graphs.
Hi Paul, This puzzled me, too. Finally, I just deleted the txt file. Looking at, it, it looks like maybe it's a weekly file. For example: Z38XXData2014CW50.Txt, seems to mean week 50. At least that's my guess, since there's also a file Z38XXData2014CW49.Txt that was last modified Sun 07 Dec 2014 05:59:54 PM CST this morning. My tests are rather targeted, so I just delete whatever the file is and restart the program without paying close attention to the name when I start a new test.

Re: [time-nuts] Z38xx rack mounts
Hi Mike, Many thanks for the information, but as I understood it the question was asked with regards to the Z38xx Telecom styled units and not those variants such as the HP58503 series that were indeed built into HP desktop cases as you describe. The HP Z3801A etc and similar units from other manufacturers, Trimble for example, meet the Nortel GPSR specification, a copy of which is available for download at Didier's web site, and do not have the physical frame structure that would accept the HP link lock kit. However, the box itself of the Z3801A unit, although in this case just a bare aluminium enclosure, is very similar in size to the body of HP's normal half rack test gear, it's really the front panel on the Z3801A that flings a spanner into the works, so for anyone prepared to remove or modify that panel the rack mounting problem becomes much less of an issue. On the question of similarities in size between the Z3801A chassis and a standard HP 1/2 rack unit, there seems to have been a number of 58503A desktop units offered for sale, generally from China but not always, that the supplier claims to have been upgraded from a Z3801A, or sometimes a Z3805A. These units do have the rubber bumpers fitted, and what looks like an HP desktop style panel, but generally seem to retain the usual Z3801A aluminium enclosure so I imagine the bumpers would just be a push fit over that. One current Ebay offering clearly shows the internals as looking very much like a standard Z3801A but makes the claim Z3801A has been upgraded by us, which the feature is the same as 58503A. A screenshot of SatStat also shows the unit identifying as 58503A but aside from the cosmetics I've never seen any clear indication of what's actually claimed for this upgrade. Are there any significant performance differences between a Z3801A and a 58503A, and was any actual HP or Symmetricom firmware ever available to make such an upgrade, or is this more likely to be purely a cosmetic exercise with someone hacking the standard Z3801A software so it now identifies as a 58503A, or perhaps something somewhere in between?

Something I've done for several projects is to seek help from these nice folk: http://www.frontpanelexpress.com/ A custom panel I did so I could rack-mount my Comcrap cable modem (along with the rest of the network gear) ran about $75 or so. What I would suggest doing with the Z38xx series is to simply do a rack panel with an appropriate size cutout, then place holes for the mounting screws and just bolt everything together.

Re: [time-nuts] Z38xx rack mounts
Yes many telco racks of old were 24 and as I recall nasa or someone had 28. That said I did what Bruce suggest some 8-10 years ago. Al panel spray painted to math the 3801 and cut a hole to fit the unit. Not having clever tools lots of drill holes a hack saw and then cleanup with a file. Came out well. I mounted the 2 in series power supplies to get to 36V in the remaining space on the panel along with on off switch fuse and light.

Re: [time-nuts] Z38xx rack mounts
Dave, I, too, hate piles of dumb little boxes. So when the Z3801 appeared I went on line, bought some sheet aluminum of appropriate thickness, cut a panel sized piece, drilled a few holes with an appropriate twist drill to allow the start of a hacksaw and then finished the clearance hole for the 3801 with a file. I supported the 3801 with some aluminum extrusion angle stock and then painted the whole she-bang with paint to match my stuff. And lo, no dumb little box, and it fits a standard 19 inch rack perfectly. If you send me an email address I will send a photo.

Plan B and a half. or C and three quarters or whatever:-) I just measured a Z3801A case, can't speak for any others in the series, and that measures 9 1/4 inches from one outside edge of the front panel to the opposite side of the box itself. Cutting off opposing edges from two front panels, either to 9 1/2 inches each or perhaps a bit less to allow for a central dividing trim, would allow two units to be mounted side by side in a 19 inch rack with panels butted up but a bit of separation between the boxes, whilst keeping the existing fixings on the two outer edges.

Re: [time-nuts] Z38xx rack mounts
It's actually not a problem, as I mentioned before the boxes themselves are only 8 inches wide and centered in the panel. If you cut each panel down to 9 1/2 inches that would leave a separation between the boxes themselves of 1/2 inch so overall width behind the panel would be 16 1/2 inches, which is quite a common size for rack mount units anyway.

Cutting off opposing edges from two front panels, either to 9 1/2 inches each or perhaps a bit less to allow for a central dividing trim, would allow two units to be mounted side by side in a 19 inch rack with panels butted up but a bit of separation between the boxes, whilst keeping the existing fixings on the two outer edges.

The Nortel GPSR (aka HP z3801a) was mounted vertically in a chassis which was itself rack mounted. It's 11 tall, not wide. ___ Wow, that helps explain things a bit. Wonder why, if they were meant to be installed vertically, they wouldn't have screened the legends to be read that way. Anyway, that insight might simplify things for me. I hadn't thought of mounting them that way. I have a couple pieces of rack mounting rails that I could cut and mount horizontally in my 19 rack and everything would fit (hopefully) just right.

Re: [time-nuts] Z38xx rack mounts
Nigel, These are standard HP 1/2 rack units. The rubber bezel around the front and back peel off. HP (Agilent, now Keysight) makes a Link Lock Kit http://www.ebay.com/itm/HP-Agilent-Lock-Link-Kit-5061-5458-/291271152251?pt=LH_DefaultDomain_0hash=item43d11d127b to connect the units. The finger piece mount in the slots in the side of the front bezel and lock together. The lock pieces strap the rear square frame posts together. Add the 2U (each 'U' is 1-3/4) rack mount flanges and you're good to go.

As regards the the Z38xx modules, my Z3801As actually measure 10 9/16 between the front panel edges but obviously still too much to fit two like that into a standard 19 inch rack. I've considered two options on this, one is to keep the existing front panel and just cut it down closer to the case itself and the other, prompted by having one arrive several years ago with a bent front anyway, is just to remove the existing front panels entirely and make up another panel to accommodate two units side by side. The actual cases themselves are 8 inches wide so two should sit side by side quite nicely in a 19inch rack.

[time-nuts] Z38XX
Gentlemen, due to the discussion that evolved concerning Z38XX i looked up the sources and found that indeed every time the current time is read using a :PTIM:TCOD? a :PTIM:TCOD:FORM F2 is sent in advance to make the receiver answer in the format that Z38XX needs. I have not been aware that this could lead to NVRAM wear out but have been thinking this simply sets the format of the next output.

Re: [time-nuts] Z38XX
Hi Ed, I had a good look around for 45 minutes and I can't find where I saw it expressly stated as a NVR command. However, referring to the Z3801a manual, for instance, page 4-8 (page 74) states that: :TCOD:FORM F1|F2 selects the format of the time code message returned by :PTIM:TCOD? :TCOD:FORM? Returns F1|F2. Note that I believe this is a NVRam setting as it is persistent over power cycles. What does Ulrich have to say about why he is sending this command every update?

Re: [time-nuts] Z38XX
Sorry, I misunderstood what you mean by Z38XX. I thought that meant the generic class of HP / Agilent / Symmetricom Z38xx (aka Z38* or 585*) GPS receivers, of which there are many. If you are referring instead to the freeware Windows Z38XX.exe program, then that indeed sounds like a horrible bug. Ulrich, can you confirm? BTW, a similar problem occurred years ago with early versions of the now popular Prologix controller. Old firmware would, for example, save the ++addr value to EEPROM any time the GPIB addr changed. Now if you used only one GPIB device at a time it made sense to preserve the setting in EEPROM; it's a convenient feature, and there was no problem. But apparently some users had multiple GPIB devices and used the controller to rapidly alternate talking amongst all the devices, thus changing GPIB addresses many times per minute! This burned out the Prologix EEPROM. In general EEPROM is intended to preserve settings over power failures or reboots, that is, rare events, not to simply hold state from second to second or hour to hour. Years ago Prologix wisely changed the default and added an explicit savecfg command to save volatile configuration changes to NVRAM, this solving the problem. So it will be interesting to hear what's really going on with Z38XX.exe and a Z3801A with FROM F2 output. Perhaps HP cleverly avoided updating EEPROM for redundant [re]configuration requests. /tvb - Original Message - From: paul swed To: Tom Van Baak ; Discussion of precise time and frequency measurement Sent: Saturday, April 20, 2013 12:44 PM Subject: Re: [time-nuts] Z38XX Tom it would indeed wear out the NVRAM especially the vintage used in the old 3801.

Re: [time-nuts] Z38XX software and HP 58503A
Stan, your observations are correct but what you may feel is a flaw of the newer versions is indeed a big improvement: Z38XX does nothing until it has identified the attched unit and knows exactly how to do with it. Identifying is not simply a means of getting an answer to *IDN? but to detect something known in the answer. Send me a log file made from the debug window and I will include the HP58503 into the group of known devices.

I recently installed the update that included the spelling corrections and displayed the date along with the time, and found to my dismay that this version no longer worked with my 58503A. Later I installed the current update (20090716) with no success, either. The software appears to be identifying the 58503A, as the response to the *IDN? command is in the lower right corner of the main window, but there is no other data collected or displayed. I tried GPSCon and it is still working fine with the 58503A, so I suspect a change in the Z38XX software itself is causing this problem. Has anyone else noticed this? If it turns out that this is a problem that will not be correctable, can someone point me to an archive with an older version of Z38XX?

[time-nuts] Z38XX
Guys, I have uploaded a new version of Z38XX with the following improvements: 1) A really god manual written by Murray Greenman is available now. It is included in the .zip file 2) The preset command list in the Manual Command Entry window is complete now 3) After 3 minutes of inactivity of the Manual Command Entry window it closes and the normal communication thread restarts automatic 4) The file naming convention for the data files has been changed. The new format is Z38XXDataCWZZ.Txt where stands for the year and ZZ stands for the current calendar week. I.e. every new week a new file is written. That limits the maximum filesize to a reasonable number and prevents the data file size from growing above any bound. In addition reading the data file(s) at the start of Z38XX will get faster. The new version is backward compatible to the older versions. Enjoy!

Re: [time-nuts] Z38XX
Ulrich, Thanks again for an excellent tool that just keeps on getting better. You have pre-empted my thoughts on adding a timeout to the manual entry mode, I got caught out by that just yesterday. I also like the new data file system. One thing with the manual entry commands, unfortunately these seem to be for the Motorola receiver as fitted to the Z3801A ( Z3816A?), I believe, and a number of them do not work for the FURUNO GT-8031B as fitted in the Z3805A that Bob (fluke.l) was selling. I have had no luck finding the command set on the Net and so have contacted Furuno to see if they will provide me with this info. So far they are asking questions about what business I am in and what I propose for future sales. If I get the command list from them I will let you have it. Thanks, Steve 2009/7/19 Ulrich Bangert df...@ulrich-bangert.de: Guys, I have uploaded a new version of Z38XX with the following improvements: 1) A really god manual written by Murray Greenman is available now. It is included in the .zip file 2) The preset command list in the Manual Command Entry window is complete now 3) After 3 minutes of inactivity of the Manual Command Entry window it closes and the normal communication thread restarts automatic 4) The file naming convention for the data files has been changed. The new format is Z38XXDataCWZZ.Txt where stands for the year and ZZ stands for the current calendar week. I.e. every new week a new file is written. That limits the maximum filesize to a reasonable number and prevents the data file size from growing above any bound. In addition reading the data file(s) at the start of Z38XX will get faster. The new version is backward compatible to the older versions. Enjoy!

[time-nuts] Z38XX software and HP 58503A
I have been using the Z38XX software (thanks Ulrich!) for a while now with my 58503A and it's worked very well. I recently installed the update that included the spelling corrections and displayed the date along with the time, and found to my dismay that this version no longer worked with my 58503A. Later I installed the current update (20090716) with no success, either. The software appears to be identifying the 58503A, as the response to the *IDN? command is in the lower right corner of the main window, but there is no other data collected or displayed. I tried GPSCon and it is still working fine with the 58503A, so I suspect a change in the Z38XX software itself is causing this problem. Has anyone else noticed this? If it turns out that this is a problem that will not be correctable, can someone point me to an archive with an older version of Z38XX? The most recent version I used that worked was the first version with the Nixie-style time display.

Re: [time-nuts] Z38XX software and HP 58503A
Hi Stan, I have all the older version of the Z38XX SW. Let me know which date do you like and I can forward to you. I did not installed yet any-one because the project not yet completed.

[time-nuts] Z38XX
Guys, I have just uploaded a new version of Z38XX with the following improvements: 1) Displays time AND date in the Nixie clock window 2) Knows how to read date time from Jackson Labs receivers, so the the clock window will function with them too. 3) Has a new Manual Command Entry which, well, allows manual command entry. The combobox still needs to be filled with more presets but you can actually type in whatever you want. Note that the normal communication thread is paused while this window is open. So close it whenever it is not used.

Re: [time-nuts] Z38XX -- Z3816A
Ulrich, First, many thanks for all the delevopment you have done and share freely. You and John Miles are both to be commended for so much of this kind of work. I have a Z3816A and tried your program. Seems it would need to be updated to support this GPS receiver. I think it is pretty similar, in commands, to the other Z38xx boxes. I wonder if you would be willing to try adding support? If you are willing to look at it, I have put some details in this message. Feel free to contact me -- rexa at xertech.net -- if you need more specifics or testing from my Z3816A. -Rex, KK6MK There are some possible serial initialization issues. The help section from GPSCon, describing this, can be found in the middle of this page: http://www.realhamradio.com/GPS_Z3816A_Receiver.htm (something odd happened with one of the pictures on that page.) The command structure is very close to chapters 4 and 5 in this document: http://www.leapsecond.com/museum/hp58540a/097-58540-01-iss-1.pdf with a similar description of the :SYST:COMM commands in this one: http://www.leapsecond.com/museum/hp58540a/097-58540-01-iss-1.pdf I used a serial terminal at 9600 baud to talk to my receiver and capture the sequence below.
