Re: [time-nuts] Looking for IEEE-488 codes and formats for Datum 9700AT Programmable Time System

Hi

Yes, there is what appears to be a socketed ROM on the board. Next step seems 
to be to dump
the ROM and see what’s inside.

Just curious, is there by chance a removable eprom or other programmable
device on these boards?

Assuming a fairly verbose scpi like command interface, I've occasionally
had luck reverse engineering a command set by looking through an eprom dump
for a list of commands?

Also, does this by chance respond to the standard scpi commands like *IDN?
and *TST?

I have two of these with 488  interfaces.
Would appreciate any 488 info you get.

Hi

Actually the manual is moot on any sort of remote control. The RS-232 
section refers you to an insert
in the back of the manual. I’d guess that the 488 stuff was done the same 
way.


Nasty question: Are you sure you have the 488 option installed?  It would 
not be the first piece of gear

produced that never really got a 488 firmware version …..

[time-nuts] Looking for IEEE-488 codes and formats for Datum 9700AT Programmable Time System

2018-04-07 Thread Tom Leedy via time-nuts 

Hi:
 
I am looking for the IEEE-488 codes and formats for a Datum 9700AT Programmable 
Time System.  The 9700AT is a 1U time generator and translator with slots in 
the back that can accept option cards with various functionalities such as -488 
and RS-232 interfaces, GPIO, and tape searches.  What I need is the character 
strings to output the time for the -488 interface.  The manual for the unit is 
here: 
http://www1.symmetricom.com/media/files/support/ttm/product-manual/man-9700at-9710.pdf
However, it is silent on the details of the -488 interface.
 
Any help would be appreciated and feel free to contact me offline.
 
Many thanks!
