The PXIe-8623 can provide Ethernet communication and network timing functions within a hardware-in-the-loop system that also includes CAN, LIN, analog I\/O, digital I\/O, sensor simulation, and other PXI hardware.\n<\/p>\n<h4>What is the operating temperature range of the PXIe-8623?<\/h4>\n<p>\nNI specifies an operating temperature range of <strong>\u043e\u0442 0 \u00b0C \u0434\u043e 55 \u00b0C<\/strong>.\n<\/p>\n<h4>What should I check before purchasing a PXIe-8623?<\/h4>\n<p>\nBefore purchasing a PXIe-8623, verify the required Ethernet speed, number of ports, endpoint or TAP configuration, IEEE 802.1AS synchronization requirements, NI-XNET software compatibility, PXI Express chassis compatibility, Ethernet cabling, and the network architecture of the ECU or DUT.\n<\/p>\n<h3>\u0417\u0430\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435<\/h3>\n<p>\n\u0417\u0435\u043c\u043b\u044f <strong>NI PXIe-8623 4-Port 100\/1000BASE-T PXI Ethernet Interface Module<\/strong> provides four Ethernet ports, up to four independent endpoints or two network TAPs, onboard hardware timestamping, IEEE 802.1AS synchronization, and NI-XNET integration. These capabilities make it particularly suitable for automotive Ethernet testing, ECU validation, gateway testing, network monitoring, hardware-in-the-loop systems, and synchronized automated test
