What is required for RS232-based computer control on the OS20-Pro LCD version?
All you need is an EIA-standard RS232C cable. It's basically a 9-pin serial port. Control software is included with the OS20-Pro, so you do not need any expertise in coding for RS232 control.
The product description states that "a through-shaft design allows for easy adjustment of the impeller position." - What does this mean?
All OS-series overhead stirrers are designed such that you can push the stirrer rod straight through the body of the stirrer in order to position the impeller wherever you need to. So, for instance, if you wanted to create the effect of having a very short stirrer rod, you could simply push the rod farther up.
Combined with the ability to adjust the OS-series stirrer's vertical position on the stand, this creates a large amount of flexibility to accommodate vessels of various heights while maintaining the ability to position the impeller at various depths.660 Scilogex 2016-08-31
