Re: Recommended Control HWs for High Voltage Platform

[Ralph Lange <ralph.lange@gmx.de>]

Hello Han,

Depending on the number of serial connections on each HV potential and 
the specs of your devices, it might also be possible to use a terminal 
server type that offers a network module (eg. Moxa 6xxx), and use a 
fiber network uplink to the terminal server. (Instead of using multiple 
fiber links for the serial connections.)
Keeping the IOC virtual and outside the HV cage is always a good idea.

Cheers,
~Ralph
