Barco MNA-420/440/620/640 Encoders/Decoders: Systems May Disconnect
Barco recalls MNA-420, MNA-440, MNA-620, and MNA-640 encoders/decoders due to MAC address conflicts causing audio/video interruptions and device unavailability in multi-unit setups.
Cathode ray tube display system encoders and decoders have same MAC address; new system setup with two or more affected units can lead to systems not functioning reliably:audio, video and/or control signals might be interrupted or fall away, displays might switch to failover and back multiple times, devices/sources/sinks might not be discovered/available, might lead to delayed/prolonged procedures
Barco is recalling its MNA-420, MNA-440, MNA-620, and MNA-640 encoders and decoders. These devices can cause audio, video, or control signals to interrupt or fail when multiple units with the same MAC address are connected in a system.

The hazard
According to the FDA, the affected encoders and decoders share the same MAC address. This can lead to systems not functioning reliably, with audio, video, and/or control signals potentially interrupted or falling away. Displays might switch to failover and back multiple times, devices might not be discovered, and procedures could be delayed or prolonged.
