They also have two USB 3.1 Gen2 and four USB 3.1 Gen1 ports for faster data transfer. In addition, these two industrial-grade ATX motherboards are integrated with the Intel® HD Graphics to deliver stunning 4K resolution, as well as fast 3D and video playback for graphics-intensive applications. They support three independent displays with DisplayPort++, DVI-D, HDMI, and VGA.
The IMB520R and IMB521R come with multiple I/O ports including four RS-232, two RS-232/422/485, two Gigabit LAN with Intel® Ethernet controller i211-AT and Intel® Ethernet connection i219-LM, two USB 3.1 Gen2, four USB 3.1 Gen1, seven 180D type A USB 2.0, eight-channel digital I/O, one HD Codec audio, one SMBus, and one PS/2 keyboard and mouse. Both of the ATX motherboards are equipped with four 288-pin DDR4-2666/2400 DIMM sockets with a memory capacity of up to 128GB to meet the needs of high-density computing applications. Furthermore, they feature four SATA-600 sockets with RAID 0/1/5/10 function to enhance data recovery capability. To ensure reliable operation across platforms, the well-designed industrial motherboards are capable of withstanding a wide operating temperature range of 0°C to 60°C. They also support watchdog timer, hardware monitoring functions and optional Trusted Platform Module 2.0 (TPM 2.0).
