The above settings apply as long as the PC connection to the external model is “Direct Connect” and
uses the UTP Crossover cable supplied in the Process Analytics Accessory Kit. If a “Patch Cable” is
used instead of the UTP-crossover cable, the button on the external modem should be in the “x”
position, which is out.
There are three basic conditions for instrument addressing:
•
Direct Connection, DHCP addressing (Dynamically-assigned instrument IP address)
•
Network Connection, DHCP addressing (Dynamically-assigned instrument IP address)
•
Network Connection, Fixed IP addressing (Fixed instrument IP address)
A separate manual has been prepared, which describes the specifics of Direct Connection and
Network Connection. Because operating platforms have different network addressing options and
requirements, this separate manual is provided as a reference document, and is the best place to
determine which setup is optimal in a given situation.
