Keysight E8491B IEEE-1394 PC-VXI連結是一個C尺寸、單一插槽的訊息式VXI模組，可讓您藉由合乎工業標準的IEEE-1394匯流排（FireWire），將PC連接到VXI主機。E8491B對於搭配E84XX主機系列的測試應用來說，是一個合乎經濟效益的選擇。它很適合必須移動大量資料的資料蒐集應用。
E8491B是一個具備Resource Manager和Slot 0能力的高速C尺寸裝置。它的邏輯位址是0，因此它永遠是主機的Resource Manager，並且通常安裝在主機的Slot 0。能夠提供較快速度的一部份原因是使用小信號（200 mV），這些信號會透過具備控制阻抗特性的雙絞線進行差動式發射。差動式信號提供了較高的雜訊免疫力。
E8491B包含一個C尺寸的VXI Slot 0模組和一條4.5公尺長的接線。不必將PC關機就能自動辨識新的IEEE-1394裝置的能力，使設定工作變得非常容易，這種設計稱為“熱插拔”。
E8491B選項001是一個OHCI式的IEEE-1394/PCI主機轉接卡。它是一個PC插入卡，能以400 Mbits/second的速度傳輸資料。這片卡必須藉由隨附的接線，連接到PC的12V磁碟機電源匯流排（某些工業用PC上面並未提供）。它有三個外部1394埠。如有必要，OHCI式IEEE-1394/PCI卡可在1.5 A下為需要電力的IEEE-1394裝置提供12 V。
