HP-IL device Seal s5801c

[Erwin]

Hurray,

I got ... a big present back :-) it's in German. Here is the translation (German to English) from his email .

Hello,
Yes, you may share this on the forum, of course, as usual with reference to the source.
We developed some HP-IL devices at the time and wrote the software ourselves with full functionality for HP-IL slaves as well as HP-IL Master.
The communication has been shown to be very robust. Thanks to the coding used, very simple pulse transformers could be used for galvanic isolation (yes, HP-IL is electrically separated), so much easier than galvanically isolated DC/DC converters and optocouplers.
The components (pulse transformer and HP-IL IC) could be easily ordered from HP at the time. It's actually amazing (if you usually look at the communication possibilities of the time), that the HP-IL system has not prevailed more in the industry.

Kind greetings

There is the information about the connector (handwriting from him) and the manual (in German). The unit is a "universal controller for asynchronous motors" and can be used as an autonomous controller for two motors without a computer.

The little history he wrote is very interesting. I'll try to get more information about this company and the other tools the did with HP-IL. Although it would be necessary to draw the connector pins and connections in electronic from.
I changed the manual (PDF) in a electronic readable format so it would be easier to make translations to other languages.

best regards
Erwin
