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. I
f your Port modules are
671-6374-00E or newer, your Port modules do not need to be modified.
Note Port modules that are used as TimeCode 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 52. 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.
