Introduction 

Connect Tech’s Blue Heat/Net enables you to remotely access your RS-232 and RS-422/485 
serial devices via your Ethernet LAN or the Internet. Once installed, you can network-enable any 
device that is designed to be connected to a serial port. Your industrial serial communication 
devices will no longer be tied to a single computer. The Blue Heat/Net hardware is easy to 
install, involving little more than plugging the unit into the appropriate locations and performing 
some simple configuration steps, as outlined in this manual.  
 
Driver setup is made easy by the Blue Heat/Net’s auto-detection feature. The software does the 
work of locating the units, and the Configuration Manager leads you through the rest of the setup 
process.  
 
The Blue Heat/Net’s firmware is easily configured with a choice of methods: web browser, 
Telnet, or direct serial connection with a terminal and/or  terminal software. Once you’ve 
configured the Blue Heat/Net to your specifications, you’ll be able to start remotely accessing 
your devices immediately.
