The RPV311 can process a maximum number of 64 analogue channels that can be
achieved using 8 acquisition modules.
The RPV311 processing unit allows connection with up to 8 RA331 acquisition
modules, up to 4 RA332 acquisition modules or up to 4 RA333 acquisition modules
respecting the maximum quantity of 64 analog channels. That is: when it is using
only RA332, it is possible to install a maximum of 4 modules with 16 analog inputs
each, and when it is using only RA331, it is possible to install up to 8 modules with 8
analog inputs each. When it is using only RA333, it is possible to install a maximum of
4 modules with 8 analog and 3 TW inputs each one (each TW board counts as 8
analogue channels). The RA331, RA332, and RA333 can be connected to the same
RPV311 processing module.
Each link on the RPV311, composed of a pair of fiber-optic connectors, is named from
A to H. For each link, an optical fibers pair is used to make transmission and
reception of data between the processing module and the acquisition modules.
Connections with acquisition modules must be made according to the sequence of
RPV311 identification: the first connection should be made with link A, the second,
with link B, and so forth.
On the RPV311, each link has an A
up when the link is receiving data of the acquisition module.
