Host and Service Ethernet communication is an available option on some packages. Ethernet connec-
tion requires specific protocols for setting IP and Mask addresses. Set the Cryochiller Ethernet settings
using the HMI - Configuration - Set Comm Params - Ethernet menus. Set PC settings as stated below.
The Cryochiller is a non DHCP connection. The host or service PC will not automatically set the IP
address. If the IP address is changed, a new connection using the new IP address must be made.
