Module Identification
The modules have either a 128x32, 64x32, or a 32x32 Crosspoint configura-
tion. The 64x32 Crosspoint configuration will allow two modules to create
a 64x64 matrix but will not allow larger matrices. The 64x32 Crosspoint
modules can only be used in slots 1 (top) and 2 or slots 3 and 4 of the 7 RU
Concerto or 8 RU C frames to create 64x64 matrices. The 32x32
Crosspoint configuration modules cannot be combined into larger matrices
but can be used in all of the Concerto frames. The Analog audio matrices
also have three Maximum Input Level specific24 dBu, +18 dBu, and
+15 dBu. The attributes of each module are identified by the last two digits
of the part number.
Table 1 identifies Analog video modules.
