EIA-449 used the EIA-422 and EIA-423 standards for media and electrical descriptions. EIA-449 was originally intended to phase out RS-232 but EIA-449 itself has been replaced by EIA-530 for circuits above ______ Kbps

20 Signup and view all the answers

The standard calls for a +200 mV to + 6 V signal, with the most positive condition being the logic 0 state. Noise is normally found in the common mode, but the balanced line uses differential inputs and outputs, which by nature have a high common mode rejection ratio, so noise is reduced as a factor in signal quality. A differential transmitter puts the transmitted signal on one line and a polarity-inverted copy of the transmitted signal on the other ______

The most common interface between a computer and, for example, a telephone modem is an EIA-232 connection with all of the hardware handshaking signals ______

In most PCs, the serial COM ports are connected to a special integrated circuit, called a UART, that can send and receive 8-bit data values via an EIA-232 circuit. These UART chips interface to the various data and handshaking signals of the EIA-232 circuit and allow software to examine and set/clear the applicable ______

signals Signup and view all the answers

If a device uses a UART for serial communications, then it is performing asynchronous serial communications in which there can be gaps between data being sent. The data is sent as one or more octets, with a special start bit and stop bit appended to each octet at the sending end by the transmitting UART. The HDLC protocol is a commonly used synchronous protocol, in which there is a unique 8-bit pattern called a flag character used to identify the start and end of a message. Specialized transmitting and receiving hardware is needed for synchronous communications because the UART chip in a typical PC cannot support synchronous transmission. Synchronous data transmission is commonly found today in all high-speed local area networking technologies ______

Just as EIA-232 use was greatly expanded by the personal computer, other buses, internal and external to the computer, have also appeared. For a long time, external line speeds required only the EIA232, then the EIA-422/485 connections or perhaps the SCSI extended bus. However, much higher speeds and the constraints media imposed on these signals required a rethinking of the serial signal organization and the software that drives it ______

The Universal Serial Bus was originally developed in 1995 by industry-leading companies. The concept was to define an external expansion bus that made adding peripherals to a PC as simple as plugging in a network jack. The design goals were low cost and true “plug-and-play” operation. Figure 3-14 illustrates a laptop computer with a root hub showing connections to a USB hub, a printer, a mouse, a wireless access point, and a ready-to-connect flash drive. It is backward-compatible with the 1.x and 2.0 version devices that run at either 480 Mbps, 12 Mbps, or 1.5 Mbps. USB version 3 operates at a higher speed and is the newest release. There are PCI Express cards available to add USB 3.0 hardware to PCs ______
