Serial Converters 

Laptop and personal computers include a variety of features including serial communications “COM” ports and Universal Serial Bus (USB) ports that allow them to communicate with other devices such as printers and digital cameras. Industrial and commercial devices such as process and temperature controllers often have EIA 485 communications interfaces (also known as RS-485) which cannot be directly connected to a typical computer. Watlow® offers a series of serial converters that provide a simple and reliable solution to connect Watlow controllers to computers and devices.

These compact serial converters offer several features that make them ideal for use in applications in which Watlow controllers communicate with a computer via Modbus® RTU or EZ-ZONE® standard bus.
