What is a 9-pin serial port used for?
DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc. Also they are used on DB9 cable assemblies for data connectivity.
What is a 9-pin serial cable?
Many early PC designs used DB9 serial ports to communicate with other computers or hardware devices. This 9-pin layout become a de facto hardware standard that enabled device manufacturers to create products that worked on a wide range of computer platforms.
What connector has 9 pins?
DB9 connector
The DB9 connector (originally named DE-9) is an analog socket, with 9 pins, from the D-Subminiatures (D-Sub) connector family. The DB9 has the smallest “footprint” of the D-Subminiature connectors. The prefix “D” represents the D-shape of the connector shell.
What is RJ48 connector?
(Registered Jack-48) A data communications interface that uses a cable of twisted wire pairs and an 8-pin modular jack. It uses the same plug and socket as RJ-45 but has different pinouts. RJ-48C is commonly used for T1 lines and uses pins 1, 2, 4 and 5.
What are the different types of RJ48 pins?
With RJ48, there are a few configurations that can be used depending on the situation and how they are to be used. One configuration uses the pins 1,2,4, and 5 while another uses 1,2,7, and 8.
What is the difference between RJ45 and RJ48 cables?
To protect the integrity of the signal, RJ48 wirings use STP or Shielded Twisted Pair cables. In short: RJ45 and RJ48 use the same connector. RJ45 differs from RJ48 in the way they are wired. RJ45 is predominantly used in LAN while RJ48 is more commonly seen on T1 lines. RJ45 is connected with UTP cable while RJ48 uses STP.
What is RS232 port pinout and configuration RS232?
COM Port Pinout and Configuration RS232 manages communication flowing between the DTE and DCE using serial pinouts of either the DB9 or DB25 variety. These D-sub connectors can terminate with an RS232 female pinout or DB25 or DB9 male connector pins. Each pin in a 9 or 25 serial connector pinout has its own distinct function.
Why is RJ48 so popular in the US?
This is very common in a lot of offices and homes and is the main reason why it has become very popular. RJ48 is used in other applications, the most common one would be in T1 data lines where the wires can extend longer distances and are often exposed to the environment.
