Communication to Vötsch oven

Hello, how to communicate to a Vötsch oven?

(in the past the name of the company was: "Haraeus Vötsch"     now: www.weiss-technik.com)

In this attached document there are two communication protocols described: ASCII-1 or ASCII-2.

Most ovens, as I have seen, communicate over ASCII-2 (e.g. $00I<CR>)

If the oven has a RS232 (25pin) connector (like the VT4010 / VT4020) this is the pinout:vötsch 25pin pinout.jpg

In this operating manual also the communication method is described:

http://doc.es.aau.dk/fileadmin/doc.kom.aau.dk/labs_facillities/control/manuals/VT4002_climate_chambe...

 

It is equal for many Vötsch (Votsch) ovens.
