25 pin serial to ethernet adapter

The converter is port-powered and derives power by amplifying the RS data lines requiring no external power at all. This converter features auto sensing data turnaround eliminating the need for software drivers or handshake flow control. This device is truly plug-and-play and simple enough for the novice.

Check that all connections comply with the connection diagrams. Perform a loop back test on two units: Connect the two RS ports. Repeat the test in the opposite direction. This software tool is great for testing converters. This highlights one of the original uses of the RS protocol, which was developed in order to let teletype machines communicate with each other through their modems.

The other type of RS Cable is the Straight-through cable. It is a one to one connector, It transmits a pin of one device that is connected to the transmit pin of another device and the receiver pin of one device is connected to the receiver pin of another device.

But still, RS has proven to be used. The reason is, RS signals spread over longer distances. Moreover, it has better noise immunity. It is proven to be compatible across different manufacturers for interfacing computer and modems. Electronic Team, Inc. By continuing to use this site, you agree to our cookie policy.

Functional Description: In addition to defining electrical characteristics, RS specifies the signals used in serial cable pinouts and serial ports. Following is a list of the signals used in an RS COM port pinout: Protective Ground -This signal is connected to the chassis ground of the metallic connector.

Common Ground - Zero reference voltage level for all the control signals. RI Ring Indicator - Detects the incoming ring tone on the telephone line.
