The TTL-ETH is the TTL logic level version of our legacy NET232. This Adapter allows you to Internet (TCP/IP) enable any device or machine with a TTL logic level serial port. Go fr om TCP/IP to TTL serial with the TTL-ETH. It features a powerful built-in device server, so you can access your TTL serial device from anywhere in the world over internet! The TTL-ETH is easily configured via a web page, and can also be set up through the TTL serial port. You can use DHCP, AutoIP or assign a Static IP address to the TTL-ETH! TTL logic level serial ports differ from RS232 serial ports in their voltages. TTL serial ports operate on positive logic level voltages, typically +5V indicates a "logic 1" and 0V indicates "logic 0". RS232 serial ports on the other hand, specify "logic 1" at +5V and "logic 0" at -5V. The TTL-ETH will not work on RS232 serial ports and may be damaged if connected to an RS232 device. Please use the NET232+ (NET232 Plus) for RS232 ports. There are two basic modes of operation, "Redirector" and "Serial Tunneling". Redirector Mode: In Redirector Mode, only one TTL-ETH is needed per TTL 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 TTL-ETH device on your network and connect to them all from a single PC! Serial Tunneling Mode: In Serial Tunneling mode, two TTL's are used to create a "Serial Tunnel" over Ethernet. This can be thought of as cable replacement. Each TTL or NET232 is configured to have a remote IP address that is the other TTL/NET232 in the pair. No software is required to be loaded on a PC. This is also an excellent option for non-windows PCs or computers. Now you can have an infinite length RS232 cable connected over the internet.
