The NET232jr is the mini version of the legacy NET232, an RS232-to-Ethernet cable adapter that enabled any device or machine with a serial port to become Ethernet network and Internet enabled. Now you can keep the IP address in the cable and exchange the serial device without having an IT person. The NET232jr can be customized to have different types of cables: RJ45, DB9/male, DB9/female or your custom connector. To help you with the possible customization options we have a selection guide available in the documentation section.
The NET232jr requires that 3.3V or 5V be supplied on the serial connector. The NET232jr features a powerful built-in device server so you can access your serial device from anywhere in the world over internet! The NET232jr is easily configured via a web page and can also be set up through the serial port. You can use DHCP, AutoIP or assign a Static IP address to the NET232jr!
There are two basic modes of operation, "Redirector" and "Serial Tunneling"
Redirector Mode: In Redirector Mode, only one NET232jr is needed per serial device. ComPort Redirector Software (free with purchase) is installed on your Windows PC to create a "virtual" COM Port (e.g. COM3). You can then use this COM port in your Software application just as you would any physical COM port attached to your PC. Create a virtual COM Port for every NET232jr device on your network and connect to them all from a single PC!
Serial Tunneling Mode: In Serial Tunneling mode, two NET232jr's are used to create a "Serial Tunnel" over Ethernet. This can be thought of as cable replacement. Each NET232jr is configured to have a remote IP address that is the other NET232jr in the pair. No software is required to be loaded on a PC. Now you have an infinite length RS232 cable that is connected over the internet. This configuration is also an excellent option for non-windows PCs or computers.
