Controller Module Identification
Vertical interval reference is required for crosspoint switching tasks. This is 
an analog video input which can be NTSC or PAL. This input is processed 
to extract vertical sync and odd/even field (if any) information. A pre-
defined programmable logic device (PLD) is used to cr
eate a switching 
strobe that is offset into line 10 for NTSC or line 6 for PAL. A video presence 
detector interrupts the processor if the video reference is missing. If this ref-
erence is missing a fake sync is genera
ted at a default asynchronous 
interval.
Concerto has three Controller modules. Two of the modules are Ethernet 
onl
y. One Ethernet Controller is labeled 
CRS2001 CONTROLLER 671-6381-xx 
with an Ethernet interface of10Base-T and the other is labeled 
CRS2001 FAST 
CONTROLLER 671-6434-xx
 with an Ethernet interface of 10/100Base-T. The 
third Controller is labeled 
CRS-MC-C2 671-6495-xx and can be set to allow 
either Ethernet or Crosspoint Bus interface control. Do not mix Controller 
types in a single matrix. See Figure 1 for help in identifying Controllers.
