In this DB25 connector, a secondary RS serial channel was also provided. But in practice, only one channel was realized.

Also on some modems there was a secondary channel, it signaled the status of the modem, while the primary one was busy with data transmission. In our time, the more 9-pin DB9 version of RS has taken root. On the diagram of the pin RS connector, the black color indicates the pins common to both types of connectors. The figure and the table below show how to connect the adapter from the pin connector to the 9-pin connector. Below is the RS connector pinout for testing computer serial port.

Data and handshake lines connected. In this case, the sent data is immediately returned back and analyzed by the standard serial port verification software. The simplest way to connect two computers together is to use a null modem RS cable. For a simple solution, a three-wire RS scheme is sufficient, where one wire is the signal ground, the second is the receiver, and the third is the transmitter.

But depending on the type of software, some kind of handshake may be required. Below are the most popular types of null modem cables for RS This simple pinout of the cable does not allow monitoring of data transmission and reception at the «hardware level», but at the software level, monitoring is possible using XOFF analysis and XON symbols.

Not all programs are able to work with such a cable. Whether a DB9 serial pinout or a 25 pin connection is used, only three of the pins are required to connect terminal devices. Each pin in a 9 or 25 serial connector pinout has its own distinct function. You can also learn RS pinout. In addition to defining electrical characteristics, RS specifies the signals used in serial cable pinouts and serial ports.

Familiar items such as timing signals and ground are included in these specifications. Protective Ground -This signal is connected to the chassis ground of the metallic connector. These signals are the primary RS signals, but the protocol allows for secondary signals as well. Using the RS protocol you can connect two computers that do not have modems by using a null modem cable. 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.
