Some routers (e.g., the CR3204-AA or the CR0808-3Gig) have fewer input or output connectors
than shown here.
All compact routers save their state in non-volatile memory. Thus, if a power loss occurs, a router
can recover almost instantly. All compact routers require a few seconds to initialize.
All compact routers have an automation port (DE9, RS-422 or RS-485).
All routers except machine control routers accept these video reference rates:
The machine control routers do not receive video reference signals.
Digital Video Routers
The 1RU digital video routers have 16×16, 16×4, or 8×8 crosspoint matrices, depending on the
model. The 2RU digital video routers have either 32×32 or 32×4 crosspoint matrices.
Figure 12-17 shows a simplified view of the digital video router:
