The AJA Io 4K Plus is the next generation of this series. The only differences related to the implementation with VizEngine and the hardware are the usage of Thunderbolt 3 as connection interface, and the fact that the Ref In/LTC In and LTC Out connectors changed places.
As with its predecessor, only the connectors SDI 1 - 4 and the Ref In connector are implemented for use in Viz Engine. For information on the connector mapping, please see AJA Hardware.
Newer devices might require an update of the firmware. 16.1.0 driver has been tested with 2021/06/23 firmware.
