Definition of Serial Cable

 

A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.

 

Benefits of Serial Cable

Serial cables, also known as serial communication cables, are used to transmit data between two devices in a serial manner, where data is sent one bit at a time sequentially over a single wire or a pair of wires.

1

Longer Distance Transmission

Serial cables are capable of transmitting data over longer distances compared to parallel cables. They are less susceptible to signal degradation, making them suitable for long-distance communication.

2

Versatility

Serial cables are compact and have fewer pins or connectors compared to parallel cables. This makes them more versatile and suitable for devices with limited space or port availability.

3

Device Compatibility

Serial cables can connect a wide range of devices, including computers, peripherals, industrial equipment, and networking devices. They provide a standardized connection method for various devices.

4

Configuration Flexibility

Serial cables allow for different configurations, such as point-to-point or multi-drop connections. This flexibility enables customized setups for connecting multiple devices.

 

What Are Serial Cables Used for Now?

 

If talking serial cables in general, they're used for pretty much the same thing as the past 60 years. Remember, USB cables are elated serial communication standards, you'd be surprised how much equipment still employs these types of ports and cables.

 

It is still quite common in commercial and industrial applications. For example, almost all commercial routers and switches include standard serial ports, so you can configure them before you've set up any of the network ports.(Tip: always carry a standard serial cable or two of varying lengths with you when you're doing anything related to a physical network set up!)

 

Yes, networks have evolved, but why fix something that's not broken and is still totally reliable? There's a lot of legacy equipment still in use today for the simple fact that it's reliable and doesn't justify a pricey replacement. And there's a good chance that legacy equipment still has a serial port somewhere. So, no matter how you define them, serial cables are still widely used today.

 

Technically, personal computers still use serial cables too. Most storage devices use serial ATA cables to connect to the motherboard. What is a serial ATA cable? The serial ATA cable allows high-speed communication via two pairs of conductors. It replaced the parallel ATA that operated at a much lower frequency.

Serial Cable Connectors and Pinouts

 

A serial cable is a type of cable that is used to connect devices that communicate using serial communication protocols. It is commonly used to establish a connection between a computer and peripheral devices such as modems, printers, and routers.

 

Serial cables consist of multiple wires that transmit data in a sequential manner, hence the term "serial." These cables typically use either a DB9 or DB25 connector on one end, which plugs into the serial port of the device, and a different connector on the other end, depending on the device being connected.

 

Serial cable connectors and pinouts vary depending on the type of device and the serial communication standard being used. The most common pinout configurations are RS-232 and RS-485. RS-232 is a standard for serial communication between devices, while RS-485 is a standard for serial communication over long distances.

 

In recent years, the use of serial cables has declined with the rise of newer communication protocols such as USB and Ethernet. These newer protocols offer faster data transfer rates and are more versatile in terms of device compatibility.

 

However, serial cables are still used in certain industries and for specific applications where legacy devices or long-distance communication are involved. While serial cables may not be as prevalent as they once were, they still serve a purpose in certain scenarios and remain an important part of the technology landscape.

Tips and Tricks for Serial Cable Storage

 

There are some other tips and tricks when it comes to Serial Cable storage.


Label your cords. This is an excellent way to keep track of them. This will save time when looking for specific cables or cords.


Use empty boxes for storage. This is another cost-effective option that can be great for keeping multiple items stored away in one easy-to-use container.


Invest in cable organizers. If you have multiple cables that need to be organized together at once, you need these. They are great for keeping multiple cables in one place without creating too much clutter or becoming disorganized.


No matter what storage method you choose when it comes to extension cords, using proper techniques will save space, prevent damage, and increase safety in your home or workspace. With simple DIY solutions available and an abundance of tips and tricks on how to store your electrical cables safely and effectively, your extension cord storage worries will soon be a thing of the past!

Definition of Parallel Cable

 

Parallel cable, a series of metal wires that enable multiple bits of data to be transferred simultaneously. Parallel cables have mostly given way to serial cables, where data is transferred one bit after another.

 

Benefits of Parallel Cable

 

Consistent Voltage

Apart from its ability to continue functioning, even if one section fails, parallel circuits also allow for components in a circuit to have the same, consistent voltage. Take a string of lights, for example. All of the bulbs within the string will be consistently bright as the current flowing through them, the voltage operating equally on every parallel element. This isn't possible with a series circuit because voltage drops as you add or take away components, possibly causing damage to the mechanism.

Safe and Reliable

A parallel circuit is reliable and safe. While series circuits don't overheat as easily and may be better for applications around anything flammable, parallel circuits are much more reliable for larger scale applications where there's no room for error.

The following parallel cable can be used with file transfer and network programs like LapLink and InterLink. The cable uses the parallel port which makes it possible to achieve higher throughput than with a serial connection at the same low costs. The cable is among others compatible with the following software.
Laplink from Travelling software
MS-DOS v 6.xx InterLink
Windows 95, 98 and ME direct cable connection
Norton Commander
Norton Ghost
Because the parallel port on a computer was mainly designed to connect printers with one-way communication, a trick is used to achieve full two way data transfer between both sides. Five error and status message inputs are redefined as data inputs. Instead of reading full bytes, the communication software reads these five bits and combines multiple groups of data back to bytes. The sender and receiver have to use the same protocol to convert bytes to groups of 5 bits and vice versa.

 

What You Should Know When Use Parallel Cable
 

In deciding to use parallel cables, there are some considerations the engineer needs to be aware of, particularly in current capacity, voltage drop and fault rating. 

 

Current Capacity
In parallel cables, the phase current is divided between two or more conductors. Typically in paralleling cables, the size and length of each cable are the same, and the current flow is equally divided between the parallel conductors. If the conductors (or lengths) are of unequal size, then the current will not be distributed evenly (i.e. the conductors will carry different currents). Where currents in parallel conductors are unbalanced, it may be necessary to provide separate overload protection for each conductor.

 

Voltage Drop
The calculation of voltage drop across a cable needs to consider the arrangement of parallel conductors. For equally loaded conductors the impedance of each conductor is the same, and the calculation is relatively easy. Where each conductor impedance varies, and there are different current flows in each conductor the calculation becomes more involved.

 

Fault Rating
For parallel conductors, the worse case fault may still be towards the fault source and may only apply to a single faulted parallel cable or conductor. Adding additional cables in parallel doe not necessarily increase the fault rating. Generally, each individual parallel cable should be rated for the expected fault level.

Ultimate FAQ Guide to Serial And Parallel Cable

Q: What is a serial cable?

A: A serial cable is a type of cable that is used to transmit data between devices, typically computers or computer peripherals, by sending bits of data one at a time in a sequential manner. It is called a serial cable because the data is transmitted in a serial or sequential fashion, as opposed to parallel cables where multiple bits are sent simultaneously.

Q: What is the use of a serial cable?

A: Serial cables are commonly used to connect devices such as modems, printers, and routers to computers. They come in various forms, including RS-232, USB, and Ethernet cables, each with different specifications and capabilities. RS-232 cables, for example, are widely used for serial communication in older devices, while USB and Ethernet cables are more commonly used in modern devices.

Q: What are the functions of a serial cable?

A: The function of a serial cable is to establish a communication link between devices, allowing them to exchange data. The cable connects to the serial ports on the devices, enabling the transmission and reception of data signals. Serial cables are designed to provide a reliable and efficient data transfer method, ensuring that the information is transmitted accurately and without errors.

Q: What is an example of a serial cable?

A: Serial cables are used for the serial transmission of data. They support communication standards such as RS232, RS422, and RS485, as well as Fibre Channel, IEEE 1394, and universal serial bus (USB).

Q: Why do we use serial cable?

A: Serial cables connect two devices to enable data transfer from one to another via a serial communication protocol, a method of data transfer that involves sending data sequentially, one bit at a time. Conversely, its evil twin parallel communication involves transmitting multiple bits of data at the same time (several streams simultaneously).

Q: What is serial cable and cross cable?

A: The pinout of the serial connectors on both sides of the cable are exactly the same with a straight-through serial cable. A null modem serial cable (frequently called a crossover cable) is used to connect two DTE devices together without the use of a DCE device in between.

Q: Is RJ45 a serial cable?

A: You'll notice the lack of RJ45 connectors. This is a specialized cable that services smaller, often portable devices. Despite the connection pieces, this is still a "serial" cable that enables terminal communication. The CAB-CONSOLE-USB-RJ45 is arguably the most modern console cable.

Q: Is serial cable still used?

A: Modern consumer personal computers (PCs) have largely replaced serial ports with higher-speed standards, primarily USB. However, serial ports are still frequently used in applications demanding simple, low-speed interfaces, such as industrial automation systems, scientific instruments, point of sale systems and some industrial and consumer products.

Q: What voltage is a serial cable?

A: Valid signals are either in the range of +3 to +15 volts or the range −3 to −15 volts with respect to the "Common Ground" (GND) pin; consequently, the range between −3 and +3 volts is not a valid RS-232 level. For data transmission lines (TxD, RxD, and their secondary channel equivalents), logic one is represented as a negative voltage and the signal condition is called "mark"

Q: Is serial cable analog or digital?

A: Essentially, serial communication uses digital inputs and outputs to send strings of ones and zeros that represent analog and digital values. They are often used in favor of individual analog and/or digital signals that would require many individual wires as well as many input and output points.

Q: What is the difference between serial cable and console cable?

A: Serial communication is commonly used for connecting devices such as computers, routers, switches, and other networking equipment. A console cable, also known as a serial console cable, is a specific type of serial cable that is used to connect a computer or terminal to the console port of networking devices.

Q: Are all serial cables the same?

A: There are several different types of RS232 cables available, including straight-through cables, null-modem cables, and crossover cables. Straight-through cables are the most common type of RS232 cable and are used to connect a DTE device to a DCE device.

Q: Are serial cables straight through?

A: A standard serial cable, also called an AT cable, has the wires inside the cable running straight through. Take a DB9 cable as an example. Pin 1 on one end of the cable would be connected to Pin 1 on the other end.

Q: How long can you run a serial cable?

A: Serial (RS-232) – The maximum cable length that we suggest is 50 feet. At lengths greater than 50 feet, there may be a loss in signal integrity which may affect data.

Q: Is serial cable the same as VGA?

A: VGA port has 15 holes and it is similar to the serial port connector. But VGA Ports have holes in it and the serial port connector has pins in it. VGA port is used to connects monitor to a computer's video card.

Q: What is the difference between serial cable and parallel cable?

A: Parallel vs Serial Cables. The cables used for parallel and serial communication look quite a bit different from each other. Parallel cables are generally thicker and shorter than serial cables, and typically have larger more complex connector heads.

Q: What are the advantages of parallel cables?

A: Parallel offers the advantage of transferring 8 data bits per I/O clock cycle, but at the disadvantage of many more pins required on the devices. On some of the DDS devices (AD9852/54/58) the parallel port offers the advantage of addressing single bytes in the device register set, whereas the serial port requires all of the bytes of a multibyte register to be loaded at one time.

Q: What is the purpose of a parallel cable?

A: A series of metal wires that enable multiple bits of data to be transferred simultaneously. parallel cables have mostly given way to serial cables, where data is transferred one bit after another.

Q: Why would you wire in parallel cable?

A: A parallel circuit has many such "off-ramp/on-ramp" loops, so that a failure in any single loop never shuts down the entire circuit. Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.

Q: Does wiring in parallel cable increase voltage?

A: With a parallel battery connection the capacity will increase, however the battery voltage will remain the same. Batteries connected in parallel must be of the same voltage, i.e. a 12V battery can not be connected in parallel with a 6V battery.
