The cable is made up of four threaded wires. Meanwhile, the remaining two cables are for data signals. There are four types of data levels in USB cable. The first one is Low Speed with transfer speed about 1. Full rate has transfer rate of approximately 12 Mbit per second There is also Hi-Speed data transfer rate approximately Mbit per second. The Super rate rate goes past that with transfer rate of Mbit per second. To be able to construct a USB cable, then you need to gather these substances.

Typically it utilizes black, green, white and red cable colors. Black cable serves as floor, exactly like in any other apparatus. The red one is to get positive cable with DC ability of 5 liter. Green and white function as data wire with green indicates negative and white as optimistic.

Use the solid cables, instead of the stripped ones. Strip about a centimeter in the ends.Q: Why do the diagrams for the RS and RS buses include resistors at the end of the bus wires and what values do I need for them?

A: Signals that reflect from the end of an unterminated bus with a high-enough amplitude can cause problems for other devices that see these reflections as real communications. The terminations are placed at the driver and receiver farthest from each other. A device with an RS or RS port might include a built-in termination resistance you can connect to a bus if needed or leave disconnected. Use only two terminating resistors! Typically, twisted pair wire has an impedance of about ohms, so we use ohm resistors at the ends on the longest cable runs.

Keep in mind the longest run might not be a straight line. You must measure all the lines in your network to determine the longest path. Remember that a full-duplex RS network requires termination resistors on both buses.

Q: Some diagrams of an RS bus show other resistors on the bus that connect to the positive power source and to ground. What do they do and should I include them? A: In an RS network, the lone driver always produces a logic-1 or a logic-0 output. It never disconnects electrically from the receivers.

Then other drivers may use the bus. The outputs of a disconnected driver go into what we call a three-state mode ; essentially a high-impedance mode that will not affect the bus. Three state modes comprise logic-0, logic-1, and high-impedance conditions.

What happens if all drivers go into the three-state mode? What signals appear on the bus? Some driver integrated circuits include a fail-safe circuit that places a three-state bus in a known state to prevent errors at receiver inputs.

Figure 5. An example of a pull-up and a pull-down resistor on an RS bus to ensure the proper voltages on an inactive bus. A: It depends. Manufacturers of equipment with RS and RS interfaces note a maximum of feet mbut the higher the communication frequency, the shorter the maximum cable length. Several sources provide a log-log plot of cable length vs.

This cable has a signal velocity of 0. So in this case, a stub from the main bus can have a length of 6. For more information about bus-length considerations and calculations, please refer to: 1. A: Short answer; yes. The CAT5e cable works well when you choose the proper pairs: blue and white-blue, green and white-green, brown and white-brown, or orange and white orange.Rs To Usb Wiring Diagram — rs to usb converter circuit diagram, rs to usb wiring diagram, usb to rs converter wiring diagram, There are various sorts of electronics on the market.

Strip to a centimeter in the endings. Following that, cover the entire cables with large skillet tube. Each cable should also be covered by smaller shrink tube. The next part is also significant in the process of creating USB cable.First check the pinout connections and specifications of the devices you want to connect in order to determine whether you need a "2-wire" RS connection or a "4-wire" RS connection.

If you can't obtain this information before selecting a converter or serial card, select a converter or device which can be easily set to work in either mode using switches, jumpers or other options. Most often you will be setting up and connecting a card or converter as a Master to one or more Slave devices. Following are figures for three types of 2-wire Master connections, and one type of 4-wire connection. Usually Termination is not required for baud rates Check the Data Sheet schematic or block diagram.

A RS device does not tri-state the transmitter so it cannot use these connections. This connection is used for a single Master in a 4-wire system. When only one master is used, the Master can be set to RS mode since the there is no need to share the transmit wire pair to the Receivers of all the devices.

All of the devices must be RS and Tri-state since the same wire pair to the Receiver must be shared by the Transmitters of all the devices. The advantage of the 4-wire connection is that all devices only see commands from the Master, and no Device sees the responses from other devices.

Turn-around delay is also not required.

Connect additional Masters the same as any Device, Figs. All devices must be able to ignore the commands to other devices and able to ignore the responses from other devices. Any device could transmit to all others if permitted or some special Protocol is established to avoid data collisions. Usually the devices are Slave type and respond only to requests from a Master Device. This connection is less common, Master 2 may be anywhere else on the network and may be used for collecting data returned from the devices.

It can monitor the data from the devices only, but is not able to monitor the data requests from the other Master without additional connections. Only one Master can talk to the Devices at a time, so one Master must stop transmitting for a time to avoid data collisions so the other Master can access the same devices, or use some software protocol established for Device sharing. When Master 2 is used as Backup, the program on Master 2 begins polling the devices when the slave Devices stop responding for a predetermined time.

In a system with 2-wire connections, try reversing the lines to see if the device will respond. In a system with 4-wire connections, try reversing the receive pair polarity and transmit pair polarity. If the connections are wrong, you won't be able to communicate because the data bits are upside down, but swapping polarity won't damage anything. Many naming schemes are in use.
