It plugs into the CB901 backplane to coordinate the system’s serial data links and overall control of AlphaCom network components across multi-stage configurations, including stage 1 and stage 2 connections. Installation requires a P2 backplane connector in card position 19 to enable the serial data path; in older CB901 racks, the NFE1683 can also be installed in position 20 if backplane pins for the serial connections are present, but if neither 19 nor 20 has connection pins, the cabinet must be upgraded to the DP979 backplane. For RS-232 data links, the CB901 uses 37-pin D-sub terminals on the processor board, with external cables such as the BF952 required for connections to the cabinet rear. In single-stage CB901 configurations without display stations, serial port 3 is available for SIO data-link connections; if the CB901 rack includes display stations, port 3 is reserved for those displays, and other ports are used for data links as documented in the installation guidance. The NFE1683 is designed to operate within CB901 hardware configurations that leverage DP979\/DP991 Basic Cardracks, and it accommodates the backplane constraints described above, including the note that in older racks, a cabinet modification may be needed to accommodate battery RAM on the card. This processor card is a core component of the CB901 ecosystem, referenced in Ring Master and AlphaCom integration contexts, and is delivered as the dedicated CPU module for CB901 system builds. \u003c\/p\u003e\u003c\/div\u003e","brand":"SRC","offers":[{"title":"New","offer_id":51713473511726,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_fee25997-00b0-43f0-b9ba-1c7cc5babef6.jpg?v=1770400742","url":"https:\/\/plgautomation.com\/products\/src-nfe1683-processor-card","provider":"PLG Automation ","version":"1.0","type":"link"}
