9-Pin Port
The 9-pin RS485 data port, located on the back of the oven, connects to the oven temperature
controller. The port is primarily intended for updating the controller software but can be used for
data logging and graphical temperature recipe programming. Accessing the controller with a
computer requires a 9-pin RS485-to-USB converter cable and driver software.
Applications and Utility Software
• National Instrument LabView and Watlow SpecView — Temperature monitoring and data
logging in graphical user interface environments.
•
Watlow’s EZ Zone™ Configurator — Programming temperature recipes in a drop-down
menu environment. Configurator can also be used to copy and save the controller
