By chang- ing the address codes and programming receiving decoders accord- ingly, the three bits offer eight possible addresses, which means that eight different pieces of equipment can be operated by the same handset. A more sophisticated application of the same technology is embodied in a multi-function encoder\/transmitter IC, which can handle up to 2048 separate commands, placed in 32 addressable groups of 64 commands each. The transmitter has a similar start\/ debounce cycle to that already described. Here the code is transmit- ted in bi-phase form, whereby a digital 1 is signalled by a rise in potential during one bit period, and a digital 0 by a fall in potential during one bit period. See Fig. 22.2. Each bit period is 1.78 ms, and as long as a key is depressed the data word is transmitted at intervals of 64 bit periods, 114 ms.  <\/p>\n<p align=\"justify\">The bit structure for the transmitted code is shown in Fig. 22.2. The \ufb01rst two bit periods are occupied with debounce and key scan- ning. The transmission begins with two start bits to set the operating point in the receiver\u2019s a.g.c. circuit, followed by a control bit (similar to the previously described toggle bit) to indicate a new transmis- sion. There follow \ufb01ve system address bits S0\u2013S4 which can be set by a selector switch on the handset or (for \u2018dedicated commander\u2019 applications) hard-wired in one of the 32 possible con\ufb01gurations. The command is conveyed by the next \ufb01ve bits C0\u2013C5.  <\/p>\n<p align=\"justify\">Because of the large number of possible slaves for this system, and  <\/p><div class=\"cktep6a0dbadfb46e2\" ><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-0778475562755157\"\n     crossorigin=\"anonymous\"><\/script>\n<!-- 300x600 television-and-video -->\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:300px;height:600px\"\n     data-ad-client=\"ca-pub-0778475562755157\"\n     data-ad-slot=\"6549443290\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.cktep6a0dbadfb46e2 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.cktep6a0dbadfb46e2 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.cktep6a0dbadfb46e2 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.cktep6a0dbadfb46e2 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.cktep6a0dbadfb46e2 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n<div class=\"vnjkq6a0dbadfb4601\" ><script type=\"text\/javascript\">\n\tatOptions = {\n\t\t'key' : '0c1eb4c533eaedb7b996f49a5a4983a9',\n\t\t'format' : 'iframe',\n\t\t'height' : 300,\n\t\t'width' : 160,\n\t\t'params' : {}\n\t};\n<\/script>\n<script type=\"text\/javascript\" src=\"\/\/www.highperformanceformat.com\/0c1eb4c533eaedb7b996f49a5a4983a9\/invoke.js\"><\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.vnjkq6a0dbadfb4601 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.vnjkq6a0dbadfb4601 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.vnjkq6a0dbadfb4601 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.vnjkq6a0dbadfb4601 {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.vnjkq6a0dbadfb4601 {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n\n<p align=\"justify\"><a href=\"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-content\/uploads\/2015\/09\/CONTROL-SYSTEMS-0257_thumb.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"CONTROL SYSTEMS-0257\" border=\"0\" alt=\"CONTROL SYSTEMS-0257\" src=\"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-content\/uploads\/2015\/09\/CONTROL-SYSTEMS-0257_thumb-250x300.jpg\" width=\"204\" height=\"244\" \/><\/a>  <\/p>\n<p align=\"justify\">to ensure standardisation between different manufacturers\u2019 equipment using it, the address codes have been standardised by the IC maker as shown in Table 22.1.
