Note
The data from ancillary sensors connected to the PPS port or RS232 ports
of the Gemini Hub will be output on
Port J
so it is essential to make
sure that this connection is fed into the computer or network where the
sensor data is to be used. Due to the higher quantity of traffic through this
port a Gigabit link is recommended to ensure sufficient bandwidth.
7.3.3. VDSL Configuration
In VDSL configuration the Gemini Hub will have a single Ethernet port (
Port J
)
which is for connection to an IT infrastructure. It will also have two VDSL ports
(
Port K
and
Port L
), as detailed below, which provide power and communications
to the Gemini heads.
VDSL Cable Length
Maximum length for VDSL and power is 300m, if power is provided
locally (e.g., by the ROV) then maximum cable length for VDSL
communication only is 1000m.
