Electronic Industries Alliance - Wikipedia, the free encyclopedia Well known EIA standards include RS-170 for video signal and RS-232, EIA-422, RS-449, EIA-485 for serial data communications, and the EIA-708 standard for ATSC closed captioning. EIA is accredited by ANSI to help develop standards on electronic components, consumer electronics, electronic information, telecommunications, and Internet security. The Electronic Industries Alliance (EIA, until 1997 Electronic Industries Association) is a trade organization for electronics manufacturers in the United States. en.wikipedia.org /wiki/Electronic_Industries_Alliance   (111 words)

Data Transmission Overview Page TIA/EIA-422-B was defined by the EIA for high-speed data transmission in rugged environments. TIA/EIA-485-A meets all the requirements of TIA/EIA-422-B, but in addition, this standard allows up to 32 drivers and 32 receivers to be connected to a single bus-thus allowing a truly multipoint bus to be constructed. Previously, EIA labeled the standards with the prefix "RS", which stood for recommended standard. www.national.com /appinfo/interface/0,1801,128,00.html   (637 words)

EIA-422 Bus Interface Description, RS422 EIA-485 devices may be used in 422 circuits, but EIA-422 may not be used in 485 circuits (because of the lack of an Enable line). How ever because 423 and 422 use the same receiver chip; going from 422 to 423 provides a differential path. One application note indicated that the combination of cable length (in meters) and data signaling rate (in bps) for RS422 should not exceed 10 www.interfacebus.com /Design_Connector_RS422.html   (982 words)

App Note Abstract: Using an LVDS Receiver with TIA/EIA-422 Data (Rev. A) Receipt of data from a TIA/EIA-422 line driver can be accomplished by using a TIA/EIA-644 line receiver with the addition of an attenuator circuit. If ground noise between the transmitter and receiver is not a concern (less than +/-1 V), a resistor divider circuit can be placed in front of the LVDS receiver to attenuate the 422 differential signal to LVDS levels. This technique gives the user a very high-speed, low-power 422 receiver. www.ti.com /sc/docs/psheets/abstract/apps/slla031a.htm   (94 words)

RS-485 (EIA/TIA-485) Differential Data Transmission System Basics - Maxim/Dallas The EIA once labeled all its standards with the prefix "RS" (Recommended Standard). The RS-485 standard was developed jointly by two trade associations: the Electronic Industries Association (EIA) and the Telecommunications Industry Association (TIA). Many engineers continue to use this designation, but the EIA/TIA has officially replaced "RS" with "EIA/TIA" to help identify the origin of its standards. www.maxim-ic.com /appnotes.cfm/appnote_number/736   (671 words)

Linux.com - Serial HOWTO: Other Serial Devices (not async EIA-232) A number of EIA standards have been established for higher speeds and longer distances using twisted-pair (balanced) technology. Besides the sync part of the EIA-232, there are various other EIA synchronous standards. Balanced transmission make possible higher speeds, and can be a hundred times faster than unbalanced EIA-232. www.linux.com /howtos/Serial-HOWTO-22.shtml   (1723 words)

Getting 422 in and out of Your SGI Although a Macintosh port consists of a differential RX pair and a differential TX pair like 422, the line drivers and receivers on these ports will detect and transmit the voltage levels in Apple's "Guide to the Macintosh Family Hardware," not TIA/EIA-422-B (and also not TIA/EIA-423-A, as some have asserted). In case you're trying to roll your own conversion cables or converters, we will tell you the pinouts of all 232, 422, and Macintosh ports on all SGI machines we know about, and where we got the information from. The O2's ports do not do 422 or Macintosh levels; you need a converter (source: man serial(7) on IRIX 6.4). www.lurkertech.com /lg/deck/serial422.html   (649 words)

RS485, RS232, RS422, RS423, Quick Reference Guide EIA standards where previously marked with the prefix "RS" to indicate recommended standard; however, the standards are now generally indicated as "EIA" standards to identify the standards organization. While the standards bring uniformity to data communications, many areas are not specifically covered and remain as "gray areas" for the user to discover (usually during installation) on his own. Suggestions are often made to deal with practical problems that might be encountered in a typical network. www.rs485.com /rs485spec.html   (1037 words)

Encyclopedia: EIA-422 RS-232 (also referred to as EIA RS-232C or V.24) is a standard for serial binary data interchange between a DTE (Data terminal equipment) and a DCE (Data communication equipment). Also, an RS-232-compatible variant of RS-422 using a mini-DIN-8 connector was widely used on Macintosh hardware until it was replaced by Intel's Universal Serial Bus on the iMac. Macintosh can refer to: Apple Macintosh (computer) McIntosh (apple cultivar) Charles Macintosh (Scottish inventor) Mackintosh (raincoat) This is a disambiguation page — a navigational aid which lists other pages that might otherwise share the same title. www.nationmaster.com /encyclopedia/EIA_422   (398 words)

What is RS-232C? - A Word Definition From the Webopedia Computer Dictionary Although EIA-232 is still the most common standard for serial communication, the EIA has recently defined successors to EIA-232 called RS-422 and RS-423. In 1987, the EIA released a new version of the standard and changed the name to EIA-232-D. And in 1991, the EIA teamed up with Telecommunications Industry association (TIA) and issued a new version of the standard called EIA/TIA-232-E. Many people, however, still refer to the standard as RS-232C, or just RS-232. Short for recommended standard-232C, a standard interface approved by the Electronic Industries Alliance (EIA) for connecting serial devices. www.webopedia.com /TERM/R/RS_232C.html   (320 words)
