Input and output boards are available in 4-input, 4-output, providing various I/O size combinations with sizes ranging from 4×4 to 64×64, depending on the FDX frame selected. The FDX series also supports HDCP and is ideal for a wide range of applications that require routing of high-resolution digital video signals.
