Field Replaceable Units
Port Modules
The Port module was modified so that the interface between the module
and the Port Backplane (9 pin D) adheres to the industry standard. This
modification (FMN 075-0731-00) applies to Port modules with part
numbers of 671-6374-00D or earlier. If your Port modules need the modifi-
cation, contact Grass Valley Customer Service. If the Port modules are 671-
6374-00E or newer, the Port modules do not need to be modified.
Note Port modules that are used as Time Code do not require this modification.

Field Modification Note 075-0705-00 corrects a problem on several Con-
certo modules. Crosspoints will not switch if one-shots time out during a
slow sync. This applies only to Concerto modules identified in
Table 55 . If
your modules are at the New Letter Version shown in the table, or newer, then
you do not need this modification. If your modules need the modification,
contact Grass Valley Customer Service.
