External Serial and GPI Control
External control of the Versio system is available over RS-422 serial connectors and GPI (General Purpose
Interface) inputs. The serial connectors and GPI outputs can also control external devices. The Versio system
supports up to 8 serial connections, 8 GPI inputs, and 8 GPI outputs. The 1 RU height requires that a
“fanout” cable is used to manage these connections. The fanout cable attaches to the Afterburner4 (AB4)
card on the back of the Versio system.
AB4 Fanout Cable
Design
A single AB4 fanout cable is provided for the serial 16 card, which allows for a
single VHDCI connection to the board while providing 16 individual RJ
connections. The cable is designed without splices within the length of the
cable. This approach reduces the number of cables; simplifies the installation,
connection, labeling, and dressing of cables; and improves the overall cabling
to the chassis.
Each port is labeled with a number and a letter starting with “1” and “A”. The
letters “O” and “
I
” have been omitted to avoid confusion with the numbers “0”
and “1”. See “Fanout Cable Pinouts” on page 27 for more details.
