What pins for serial communication?

Serial communication devices make use of 9 or 25 pin D-type connectors for their cabled connections. They are commonly designated as DB-9 or DB-25 with the number used to differentiate between the pin counts.

What is the pinout for Ethernet cable?

Pins 1 and 2 must be a pair. Pins 3 and 6 must be a pair. Pair refers to two wires, typically of a common color base, twisted around each other within the larger cable. To allow for a straight-through cable, the switch provides an internal transmit/receive crossover function….Ethernet Cabling Specifications.

Function	Pin#	Pin#
TX-	2	2
RX+	3	3
RX-	6	6

How do I make a 9 pin serial Ethernet cable?

1. Step 1: Strip the Serial Cable.
2. Step 2: Map the 9 Pin Holes to Inner Cables Using Multimeter.
3. Step 3: Remove Unnecessary Inner Wires.
4. Step 4: Strip the Ethernet Cable.
5. Step 5: Determine Designated Inner Wires for Ethernet Cable.
6. Step 6: Remove Unnecessary Inner Wires From Ethernet.

What is a RS-232 pinout?

RS-232 serial interface. RS232 is the interface mainly used for serial data communication. It supports data transfer rate from about 110bps to about 115200 bps (bits per sec). Hyper terminal is the application mainly used to check serial communication port of the computer, often referred as COM port.

What is the port with 9 pins?

DB9 Serial Ports
DB9 Serial Ports 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 is the 9 pin serial port?

DB9 connectors are designed to work with the EIA/TIA 232 serial interface standard, which determined the function of all nine pins as a standard, so that multiple companies could design them into their products. DB9 connectors were commonly used for serial peripheral devices like keyboards, mice, joysticks, etc.

Which four wires are used in Ethernet?

Well, there is 4 pairs of wires in an Ethernet cable. Orange/orange white, Green/ GW, Blue/BW, brown/BW. Ethernet used from FTTH to gateway depends on the service. 10BaseT and 100BaseT operate off of 2 of the four pairs.

Which ports have 9 pin male connectors?

The Serial Port Most new computers have two COM ports with 9 pins each; these are DB-9 male connectors.

What is the pinout and configuration of the DTE-DCE port?

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.

What is the pinout of RS232 connector?

RS232 Pinout. Below is the pinout of a typical standard male 9-pin RS232 connector, this connector type is also referred to as a DB9 connector. A computer’s serial COM port (DTE) is usually a male port as shown below, and any peripheral devices you connect to this port usually has a female connector (DCE).

Is the pinout the same on all Ethernet cables?

The pinout is always the same for Ethernet cables. Straight through LAN cables are the most common, and the pinout is the same if they are Cat5e, Cat6, or Cat 7.

What pins are not used in Ethernet connector?

Pins 1 & 2 (green) and pins 3 & 6 (orange) are used for data communications while pins 4 & 5 (blue) and pins 7 & 8 (brown) are not used. How many pins does Ethernet use in a RJ45 connector?
