Although setpoints can be entered manually using the front panel keys, it is much easier to use a
computer to download values through the communications port. A free program called 239PC is
available from Multilin to make this as convenient as possible. With 239PC running on your personal
computer under Windows it is possible to:
• Program/modify setpoints
• Load/save setpoint files from/to disk
• Read actual values
• Monitor status
• Plot/print trends
• Read pre-trip data and trip record
• Get help on any topic
• Print the instruction manual from disk
The 239PC software allows immediate access to all the features of the 239 with easy to use pull
down menus in the familiar Windows environment.
The 239PC software can run without a 239 connected to a computer and save settings to a file. If a
239 is connected to a serial port on a computer and communications is enabled, the 239 can be pro-
grammed from the Setpoint screens. In addition, measured values, status and trip messages can be
displayed with the Actual screens.
The 239 communications is setup as shown in the figure below.
