AVerMedia CN312MW M.2 HDMI and SDI Frame Grabber with 2K60 Inputs and -20 to 70 °C

Embedded PCs in industrial cabinets and machine-side enclosures can run well outside an office temperature range, and the capture card has to cope with the same conditions as the host. The AVerMedia CN312MW is the wide-temperature build of the CN312M, rated -20 °C to 70 °C with 0.5 m/s airflow, carrying one HDMI 1.4a and one 2K SDI input on an M.2 2280 card. The CN312MN is the 0 °C to 40 °C standard build, and the CN312MC adds conformal coating to this wide-temperature design.

The SDI input accepts up to 2048 x 1080 at 60 fps and the HDMI input up to 1920 x 1200 at 60 fps, with recording at 1920 x 1080 and 60 fps. Driver output is 8-bit in NV12, I420, YV12, YUY2, YUYV, UYVY, IYU2, BGR24 or BGR32, and 10-bit input signals are accepted. Audio is embedded on both inputs at 32, 44.1 or 48 kHz.

The CN312MW connects over PCIe Gen2 x2 in an M.2 2280 Key M slot and draws 3.3 W. The package includes a BNC cable and an HDMI micro coaxial cable. Multi-card operation is supported, and AVerMedia provides Windows drivers and Linux V4L2 drivers for x86 and x64 hosts. For two SDI sources, the CN312SW is the dual-SDI wide-temperature card.

The CN312MW is rated from -20 °C to 70 °C in operation with 0.5 m/s airflow and -40 °C to 85 °C in storage, at 0% to 95% RH, with FCC and CE marks. Its taller heatsink needs clearance above the M.2 slot, which we check when we choose the host. We supply the CN312MW fitted and tested in the host computer it will run in, with cables routed, drivers installed and both inputs checked before it ships.
