This asynchronous interface supports daisy-chaining up to 31 devices via a standard serial cable, facilitating extensive system configurations. The PCI-485I\/2 features a DB-9 male connector with allocations for both RS232 and RS485 connections, ensuring compatibility with a wide range of devices. With a maximum transfer rate of 460.8 kb\/s and a 64-byte FIFO buffer, the device offers efficient data handling for demanding applications. The channels on this interface are optically isolated, enhancing protection against electrical disturbances. Built for 3.3 V and 5 V PCI slots, the PCI-485I\/2 supports a plug-and-play installation process that simplifies configuration without the need for physical switches. Under typical operational conditions, it consumes 800 mA from the PCI bus, with a maximum draw of 1300 mA. The PCI-485I\/2 is compatible with Windows 2000\/NT\/XP\/Me\/9x-based personal computers, allowing it to function as a standard serial port for existing applications. Furthermore, it can be integrated with development environments such as Visual C++, Visual Basic, and NI LabVIEW. The device includes integrated data line ESD protection, safeguarding against surges of up to 15 kV. The designation \"I\" in PCI-485I\/2 signifies its isolation capabilities, distinguishing it from the non-isolated standard model, PCI-485\/2 (Part Number: 777641-02). Additional variations include the 4-channel PCI-485\/4 (Part Number: 777641-04) and the 8-channel PCI-485\/8. The technical specifications support diverse usage scenarios, making the PCI-485I\/2 an ideal choice for professionals seeking reliable serial communication solutions.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683849031916,"sku":"PCI-485I-2","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_13c7d8db-a56e-4c76-b131-e1b036399fb8.jpg?v=1753243120","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-pci-485i-2","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
