AVerMedia CN312MC M.2 HDMI and SDI Frame Grabber with Conformal Coating and Extended Temperature

Process plant, washdown areas and dusty production halls are hard on bare electronics, including the capture card inside an embedded PC. The AVerMedia CN312MC is the conformally coated build of the CN312M, adding a protective coating against moisture, dust and chemicals to the wide-temperature design, with one HDMI 1.4a and one 2K SDI input on an M.2 2280 card. The CN312MW is the same card without the coating, and the CN312MN is the 0 °C to 40 °C standard build.

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 CN312MC 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 in a wide-temperature build, see the CN312SW.

The CN312MC 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 CN312MC fitted and tested in the host computer it will run in, with cables routed, drivers installed and both inputs checked before it ships.
