Using the above, the 4 working inputs will be spread across the /dev/video's as shown in the table below.
This tells the driver that a Geovision GV-800 card is present but unlike the GV-800 the "master" card needs to be the last 2 numbers, as the multiplexers are controlled by the last 2 detected 878A chips. To use the card with an unpatched kernel, create the file /etc/modprobe.d/nf with the line below. The card is not properly supported with the bttv driver, but it is possible at present to use 4 of the 16 video inputs without having to patch the kernel.Īlternatively there is an experimental patch for 3.14 kernels which should allow all 16 video inputs to be used.
Each is fitted with a cable which branches out into 8 yellow BNC connectors which are labelled VIDEO 1(9), VIDEO 2(10) and so on up to VIDEO 8(16). The card has 2 DE-15 (VGA shaped) sockets. The UDP Technology NCP3200v2 is a PCI card with 16 video inputs and 8 Conexant Fusion 878A (also known as BT878) chips. 2.2 Patching the kernel for 16 video inputs.2.1 Using an unpatched kernel for 4 inputs.
