Connectors and Ports
The following connectors are provided with the AMP Gen-7 device. They are included in the shipping
container with the server.
VHDCI Breakout Cable (1)
RJ-12 to DB-9 Master Adapters (4)
RJ-12 to DB-9 Tributary Adapters (4)
MDR-X75HD-Coax Cables (2)
HD-BNC Male to BNC Female Cables (9)
AMP Gen-7 supports eight RS-422 serial ports. These ports are typically used for automation control
with one port assigned to each server channel.
The physical ports are provided via the VHDCI Breakout cable which attaches to the After Burner 4 (AB4)
card on the back of the server. The Breakout cable terminates in eight RJ-12 connectors pinned as
Master
. Eight general purpose interface (GPI) connectors are also available via the Breakout cable.
The eight RJ-12 to DB-9 adapters can be used as necessary depending on the equipment you are
connecting to the Nexio system. These adapters have built-in master and tributary pin conversions and
are labeled
Master
and
Tributary
. You can use the adapters with the Breakout cable to effect a direct
connection to ADC or D-Series automation. You can also connect to most RS-422 controllers such as DNF
Controls, HiTech, JL Cooper and other automation device servers.
VHDCI Breakout Cable
The Breakout cable connects to the AB4 board on the server via a single VHDCI connector. On the other
end, 16 individual RJ connectors provide eight RS-422 serial ports and eight GPI ports.
Each port is labeled with a letter starting with 1 and A. (For example: 1A, 2A, 3A.) The letters O and I
have been omitted.
