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.

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

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