Connect Tech Blue Heat/Net Sync User Manual
Revision 0.03 9
Introduction
Connect Tech‟s Blue Heat/Net Sync allows remote access to synchronous/asynchronous serial
devices via an Ethernet LAN or the Internet. Blue Heat/Net Sync network-enables serial
communication devices that are designed to be connected to serial ports so that the devices no
longer need to be tied to a single computer.
The Blue Heat/Net Sync hardware is simple to install as it involves little more than plugging the
unit into the appropriate locations and performing the configuration steps outlined in this
manual.
Driver setup is made easy by Blue Heat/Net Sync‟s auto-detection feature. The software does the
work of locating the units, while the Configuration Manager leads you through the rest of the
installation.
Blue Heat/Net Sync‟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 the Blue
Heat/Net Sync has been configured to your specifications, you will be able to remotely access
your devices immediately.
