This is correct, the device is single channel/half duplex. The A/B inputs and outputs are to support key/fill or dual-link SDI. The card should support external keying up to 1080i, above this the outputs switch to dual-link. To get a key/fill pair (up to 1080i) you need to send the card a 32-bit image.
