The older types of disk drive using IDE (or PATA) cables, and printers used to be connected with 25 pin connectors are parallel cables - there are multiple data lines which carry different bits of the data at the same time. We connect the positive side and negative side of the battery to the bulb separately. The same mechanism is used in UTP cable to transfer the data. Crossover cables are generally used in the server room to connect routers and switches, those big … to pin 1 at the other end of the cable. If either device on the two ends of the Ethernet cable have Auto MDI-X, then it does not matter if you use a cross-over or straight-through cable. Both NIC and switch port have an eight pins slot. That’s all for this tutorial. EIA/TIA-568-A or EIA/TIA-568-B standard Any of one use at both ends of the cable. It is in accordance with either the T568A or T568B standards. Let’s understand how to make both types of cable in detail. In short, as we use two PCs (same devices), straight cable will connect TX to TX and RX to RX of two computers, so the devices wouldn't be able to communicate. Straight-Through refers to cables that have the pin assignments on each end of the cable. The following image shows this example. If not, it is a crossover connection. Crossover cable. If not, it is a crossover connection. Any time that we are connecting a device from one category to a device in the other category, we use a standard straight through cable. The following image shows how the electric circuit builds between the sender and receiver nodes. DTE normally refers to the serial port on a PC or terminal, while DCE refers to a modem or other type of communications device. The cable is called wipe, patch cord, straight-thru cable. All Rights Reserved. Assuming that you don't what to use any auto cross over functionality that ports might have. Simple Null Modem Cable. In Straight-Through cable both the end is terminated with the same standard i.e. In the below section, we will understand which wires of the UTP cable are used to the electric circuit between nodes. If you were to use a straight-through cable (where the wires are all-in-line), then a “send” would be going to a “send” and a “receive” to a “receive”, so the devices would not be able to communicate. The transmit and receive lines are not cross-connected in this case, hence the name. The following table lists the wire positions of the cross-over cable on both sides. A straight-through serial cable is the most common type of serial cable, used to connect a Data Terminal Equipment (DTE) device (for example, a computer) to a Data Communications Equipment (DCE) device (for example, a modem). © Decisive Tactics, Inc. - All Rights Reserved, Crossover or "Null Modem" vs. Straight Through Serial Cable. Depending on the type of device on each end of the line, you either need a straight-through or a null-modem ("crossover") cable in order to communicate. Twisting the wires in pairs removes the effect of cross talk. If we ever need to connect two devices that are in the same category, we should be thinking about a crossover cable. The two networks are used along with pairs of transmitting and receiving. Straight-Through wired cables are most commonly used to connect a host to a client. These cables share the same physical characteristics as other types of network cables except that patch cables tend to be a shorter length. 16) Explain clustering support Clustering support refers to the ability of a network operating system to connect multiple servers in a fault-tolerant group. In other words, Pin 1 connector A goes to Pin 1 on connector B, Pin 2 to Pin 2, etc. Conventionally, MDI is used on end devices while MDI-X is used on hubs and switches. Keep in mind that many modern devices use Auto MDI-X, which is a way for a device to automatically switch the wiring method on its own.
