Model ET-1
EtherTerminal
Etherterminal One Product Manual
Functional Overview
The ET-1 bridges the gap between your LAN-connected PC and just about any device that
communicates with a standard RS-232 port.
In a typical application, the ET-1’s ethernet port connects to a hub or switch on your Local Area
Network. The RS-232 port of the ET-1 connects to the serial port of the device you wish to
have network-based connectivity to.
At the etherstuff.com website, we provide Etherset, the ET-1 configuration utility free of
charge. This utility makes the one-time setup of the ET-1’s IP address and serial parameters a
breeze. Once the ET-1 has an IP address, you can also control the characteristics (baud rate,
start and stop bits, parity) of the serial port using the ET-1’s built-in Webserver. Simply use
any web browser and browse the IP address you’ve already set up for the ET-1.
The ET-1’s serial port is electrically just like your
PC’s RS-232 serial port. It has a male D-Sub 9 pin
connector configured as a DTE device (just like
most PCs). It can operate over a range of standard
COM port speeds from 1200 baud to 115kbaud.
Once setup is complete, you simply open a
connection, with Hyperterminal or your favorite
telnet software, to the ET-1’s IP address and your
serial only device is controlled through an ethernet
connection.
Devices that require serial device drivers in Windows can also be connected using the ET-1 if you
install the free COM port redirector software from the etherstuff.com website.
