The connection is a RJ-12 phone jack. Figure 31B represents the connection between the serial port and
the host device.
A serial communications kit containing adapter plugs are available from FCI for both the DB-9 and DB-
25 connectors which allow the use of standard 6 wire phone line cord between the RJ-12 serial port and
the host device. The order number for the Connector kit is 014108-01.

Multiple Groups
The flowmeter is calibrated at the factory in a test stand that duplicates or models the customer
application. The calibration process produces the information needed to relate RTD signal to an actual
mass flow rate. That calibration information is entered into the flowmeter. Information about the
customer's process such as pipe inside diameter and the process standard density is also entered.
Situations exist where a pipe or duct may have two or more distinct process flow streams or the
flowmeter needs to be used in more than one installation. The flowmeter can accommodate three sets of
calibration information, therefore it can be used to monitor multiple flow streams or used in multiple
installations. Each set of calibration information is called a Group. The factory has determined from the
application data supplied at the time of order whether the flowmeter would benefit from using multiple
Groups . If multiple Groups are not used in the flowmeter the following section can be skipped. If
multiple Groups are used, all the information necessary has been entered into the flowmeter. However,
the method and conditions that determine the current Group can be altered.
