1、 ANSI/CEA Standard F-Connector Color Coding for Home Television Systems ANSI/CEA/CEDIA-897 R-2010 November 2010 NOTICE Consumer Electronics Association (CEA) Standards, Bulletins and other technical publications are designed to serve the public interest through eliminating misunderstandings between
2、manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence of such Standards, Bulletins and other technical publications shall not in any re
3、spect preclude any member or nonmember of CEA from manufacturing or selling products not conforming to such Standards, Bulletins or other technical publications, nor shall the existence of such Standards, Bulletins and other technical publications preclude their voluntary use by those other than CEA
4、 members, whether the standard is to be used either domestically or internationally. Standards, Bulletins and other technical publications are adopted by CEA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, CEA does not assume any liability to any pa
5、tent owner, nor does it assume any obligation whatever to parties adopting the Standard, Bulletin or other technical publication. This CEA Standard is considered to have International Standardization implication, but the International Electrotechnical Commission activity has not progressed to the po
6、int where a valid comparison between the CEA Standard and the IEC document can be made. This Standard does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate safe
7、ty and health practices and to determine the applicability of regulatory limitations before its use. (Formulated under the cognizance of the CEA/CEDIA R10 Residential Systems Committee.)

However, to provide a consistent reference for manufacturing conformity, the following colors are recommended from the PantoneColor Formula Guide. In this guide, all color numbers are followe
9、d by a “C” denoting swatches for coated printing stock. The color examples shown in Table 1 may vary in appearance depending upon CRT calibration, printer, paper quality, etc. For exact color references, users should consult a recently published Pantone color guide.

In many cases, inputs and outputs may most appropriately be denoted as white or unmarked. The colo
14、r blue shall be used for connectors designed for use with Series 6 drop cable, formerly known as RG-6 type cable, such as for connection to coax cable with #18 AWG diameter center conductor. Connectors with DC voltages should not be color coded white or black. 5 Implementation Companies should use b
15、lack for Antenna/Cable Inputs wherever unambiguous distinction between input and output connections is needed. Cable manufacturers should use the color coding proposed for all cables designed, manufactured and marketed for the connections identified in CEA-897. Color coding need not be applied to th
16、e shield or insulation over the length of cable. The native color of the cable may be visible throughout its length, with indication of connection type at the ends only. If this is done, color coding should be used to identify connector ends, for example, by use of appropriately colored heat shrink
17、tubing, a color ring or a sticker, or other equivalent means. . Electronic component manufacturers should incorporate a color-coding marker or indicator, consistent with CEA-897, such as stick-on color labels, screened color indicators or colored plastic inserts for the input/output jacks themselves
18、. Additionally, concise labeling at the appropriate input and output terminals or connection points on component back panels is recommended. Cable accessory manufacturers of devices such as barrels, wall-plates, switches, and splitters are encouraged to incorporate a color-coding marker or indicator
19、, consistent with CEA-897, such as stick-on color labels, screened color indicators or colored plastic inserts for the input/output jacks themselves. In the case of simple 1:2 splitter/combiners that may be connected in either configuration, it is suggested that all terminals be coded white or unmar
20、ked. User manuals should indicate the use of color-coding and reinforce the scheme. See Annex A (informative) for color coding examples in common configurations. CEA/CEDIA-897 3Annex A (Informative) Color Coding Examples in Common Home Television System Annex A provides examples of color coding that
21、 should be used in common situations involving F-connectors. NOTEAdditional A/V and/or audio connectors may be included in these configurations. See EIA/CEA-863. A.1 DTV with Terrestrial TV Input Example This example demonstrates color coding for a situation where a DTV is connected to a terrestrial
22、 Antenna. See Figure 1. DTV1Figure 1 DTV with Terrestrial Input Example As shown, connector 1 is color coded White. Optionally, connector 1 may be color coded Black. A.2 VCR/DVD Example This example demonstrates color coding for a typical VCR or DVD recorder/player. See Figure 2. The two connectors
23、are both intended to carry DTV signals. VCR/DVD1 2Figure 2 VCR/DVD Example As shown, connectors 1 and 2 are color coded White. Optionally, connector 1 (input) may be color coded Black. A.3 Cable Set-Top Box Example This example demonstrates color coding for a situation involving a cable set-top box.
24、 The connectors are intended to carry TV signals. Connector 1 is expected to be attached to a service input. See Figure 3. Cable set-top box and TV1 2 3Figure 3 Cable Set-Top Box Example As shown, connectors 1, 2, and 3 are color coded White. Optionally, either or both connectors 1 and 3 (inputs) ma
25、y be color coded Black.

27、th satellite and terrestrial TV signals are carried. See Figure 5. diplexer diplexerSatellite diplexers and set top box213 465STB879Figure 5 Satellite Diplexers and Set-Top Box Example As shown, connectors 1, 5, 7 and 9 are color coded White; connectors 2, 6 and 8 are color coded Blue; and connector

A.6 Amplified TV Antenna Distribution Example This example demonstrates color coding for a situation involving a terrestrial TV antenna, line amplifier, attenuating splitter, and
29、 multiple TVs. Terrestrial TV signals are carried. See Figure 6. CEA/CEDIA-897 515AMPAmplified antennadistribution to multiple TVs2634splitter6Figure 6 Amplified TV Antenna Distribution Example As shown, all connectors are color coded White except for connectors 2 and 3, which are color coded yellow
30、. Connector 2 is an amplified output intended for home distribution, and connector 3 is input to a splitter intended for home distribution. Optionally, connectors 1, 5 or both of 6 may be color coded Black (Antenna input). Alternately, connector 2 may be color coded White or unmarked if the line amp
31、lifier shown is intended for output to a single device. Connector 3 may be color coded White or unmarked if the splitter shown is not intended for use in distribution to multiple devices.
