Betreff: Datron 1281 / 1271 secret GPIB cmds for CALRAM-Readout
Hi volt-nuts
I like to backup the Datron 1281 CAL RAM data. Mine need to be refurbished (caps replacement, case cleaning...)
The 1281 quite good in cal (~3ppm difference to my 3458A which had last cal 2014/OCT), which I don't want to risk.
In any case this migh a helful knowledge for all of us.
I am lucky having another 1281 "for part" without a Display- and DC-Assembly but a wokring Digital Board.
I dumped the ROM to have a deep look into the GPIB commands and searched for potential undocumented existing
(like it was done for the 3458A already).
I found following, in the service and user manual not documented, potential commands (?):
RAM = may a RAM command, seems to be the best chance
PRIM = may a subfunction of RAM for primary RAM
SECN = may a subfunction of RAM for secondary RAM
IPZ = no glue yet
YEUK = command to set something, no glue yet about function
YEUK? = query comand of the YEUK command
CALISS? = seems to be a qery for calibration purpose
To (hopefully) save some of the allways limited private time, I would like to aks, if some of you have seen that commands (?) or have more details on them. They may used at other Daltron tools also...
Next I will start with the debugging of the unknown remaining commands on processor board level.
Thanks for help already in advance.

PeLuLe,
I am currently working on two 1281's. If you have anything you would like
me to try, let me know. I am certain my cal constants are not good on one
of them. The battery was just changed a few days ago and it appears to be
the original from '87. I also had some intermittent NVRAM errors.
Replacing caps worked for the first 1281 and cleared the DCV 2182 error.
The project is a WIP and everything is being documented on xDevs.
Also, please post your FW versions. Both of mine are at different revs and
I would like to know the different versions from Datron/Wavetek

Thanks for the link, Todd.
It's a great site, I didn't find, even I looked for it. I regular check xDevs for interesting project.
I have looked to the page and found a minor errors I like to note:
The "Datron 1281 Calibration and service manual, Volume 1, Issue 1, July 1989"
in fact is the complete SM (Vol1 and Vol2), I know as I have uploaded to KO4BB myself :-)
My firmware is: v3.12, 05/11/96. I have placed the ROM files to a Dropbox folder.
On the site is mentioned, you are looking for the specs of the DC405E2 (VFD 1x40 DOT Matrix Display).
I could manage to get the original spec from ITRON service some years ago (I am a good customer).
I have optimized and added some useful information. I dropped to the Dropbox also.
I had the plan for a "Datron 1281 DC4052 replacement". Mine was broken on shipping.
I have added a picture of latest state of project.
It's on hold, as I got a complete Display Assembly and had no need for anymore.
I will keep the Dropbox for one week, than I will delete as I need the space for a joined project.

PeLuLe,
Thanks for your help. I have been following you on EEVblog too. I go by
ManateeMafia. TiN has been very helpful at getting my article together and
he has a good way of explaining the info, He has been helping with the
photo editing too as you can tell from his other articles he likes lots of
detail,
If you don't mind, I will share the dropbox link with him and he will place
the info into the article with the proper credit given to you. The
firmware is helpful and I believe my second meter has the same version.

On the site is mentioned, you are looking for the specs of the DC405E2

I could manage to get the original spec from ITRON service some years ago
(I am a good customer).
I have optimized and added some useful information. I dropped to the
Dropbox also.
I had the plan for a "Datron 1281 DC4052 replacement". Mine was broken on
shipping.
I have added a picture of latest state of project.
It's on hold, as I got a complete Display Assembly and had no need for

I will keep the Dropbox for one week, than I will delete as I need the

PeLuLe,
I am currently working on two 1281's. If you have anything you would
me to try, let me know. I am certain my cal constants are not good
of them. The battery was just changed a few days ago and it appears
the original from '87. I also had some intermittent NVRAM errors.
Replacing caps worked for the first 1281 and cleared the DCV 2182
The project is a WIP and everything is being documented on xDevs.
Also, please post your FW versions. Both of mine are at different
