– Hardware Design
36 RPV311-TM-EN-7
1.1 Processing Capability
The RPV311 has 8 link connections to communicate with RA33x acquisition units. As
each acquisition unit has different number of channels and functions, they require
different levels of demand from the RPV311. In order to respect the RPV311
processing capability the number of RA33x that can be connected to the RPV311
obey the following rule:
The RPV311 can process 12 logical slots and each RA demands the following number
of slots.
The user can combine the RA units as long as the logical sum of the slots value of
each RA do not exceed the maximum number of 12.
Note:
Differently from the RA331/332 the RA333 has two link: One for the DFR
functionality and another for the TW functionality.
