You can easily set temperatures for the E5EN-H/E5AN-H with the CX-Thermo Support Software and the infrared communications port on the front of the E5EN-H/E5AN-H. You can connect a E58-CIFIR USB-Infrared Adapter Cable between the USB port on a computer and the infrared peripheral port on the front of the E5EN-H/E5AN-H. This allows you to easily set the temperature from the front panel without the loss of the dustproof, drip-proof structure.
