The PRT1 and PRT2 channels support RS-232, RS-422, and RS-485 signaling and can be configured for DF1 communications, enabling direct connections to third-party devices such as printers, serial modems, or other controllers. A separate DH485 port links the SLC 500 controller to a DH485 network for multi-node communication with compatible devices. As a BASIC language module, 1746-BAS executes user programs on the SLC controller and serves as a bridging interface between the controller and external serial equipment. In operation, if PRT2 is configured for DF1 or used for a DF1 interface, the DH485 port is disabled, reducing network connectivity. Catalog Number 1746-BAS denotes this legacy SLC 500 BASIC module used in older installations and typically installed in an SLC 500 chassis with the appropriate backplane power considerations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51658982588718,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_c201d94a-2506-4396-b67d-5275a650f85e.jpg?v=1769526296","url":"https:\/\/plgautomation.com\/products\/allen-bradley-1746-bas-slc-500-basic-module-2-port-dh485","provider":"PLG Automation ","version":"1.0","type":"link"}
