Serial Communication Cable Types

The cables that carry digital video are almost invariably serial such as coax cable plugged into a hd sdi port a webcam plugged into a usb port or firewire port ethernet cable connecting an ip camera to a power over ethernet port fpd link etc.

Serial communication cable types.

However special network adapters sometimes called dongles connect an ethernet cable to a usb port indirectly. Typical rs232 serial data cable. Serial standards rs 232 communications is the most popular method of plc to external device communications. The rs232 cable shown above gives the more likely connections seen in an rs232 cable.

Control cables are used to connect instrument transformers coils of circuit breakers and contactors control switches meters protection devices and other control and monitoring equipment. Dte data terminal equipment and a common example is a computer. The transmission modes are classified as simplex half duplex and full duplex. It has an uninsulated ground wire is not counted in the number of wires.

Rs 232 is a communication interface included under scada applications. Most universal serial bus usb cables connect a computer with a peripheral device such as a keyboard or mouse rather than to another computer. There will be a source also known as a sender and destination also called a receiver for each transmission mode. Types of cables used in control communication control cables.

Other standards such as rs422 and rs423 are similar to rs232 although they permit higher transmission rates and longer cable distances. The form of connectors depends on the particular serial port used. Types of serial cables. Usb cables feature twisted pair wiring.

This serial communication standard is widely used and is often equipped on computers as standard. They are null modem and straight cable. A serial cable is a cable used to transfer information between two devices using a serial communication protocol. A suitable cable is shown below.

Shielded cable has a layer of foil that blocks signal interference from nearby equipment and devices. Serial communication can take many forms depending on the type of transmission mode and data transfer. Transmission modes serial communication. In null modem cable the tx transmitter pin of the male connector is linked up with the rx receiver pin of the female and the rx pin of the male is connected to tx pin of the female.

Serial cables are typically used for rs 232 communication. There are 2 types of rs 232 devices. According serial data cables for these systems require the additional lines to be incorporated into the serial data cables for them to operate correctly.
