Electrical And Communication - Gemini 620pd Profiling Product Manual

Gemini Hub Installation

8.3. Electrical and Communication

DE-9 Serial Connectors
Ports A to H are for serial devices and work on the RS232 protocol. The
corresponding LED on the front panel (A to H) indicate:
• RED Receiving data.
• GREEN Transmitting data.
• ORANGE Receiving and Transmitting data.
Ethernet and VDSL Connectors
The Ethernet and VDSL ports will be in the same location on the rear of the Hub and
are marked as Port K and L. The Hub will be configured for either Ethernet or VDSL
operation and it is not possible to change between the two.
The connector should be wired according to the pin out specification found in
Chapter 7, Gemini Hub Specification. The Hub can provide power as well as
communications to the sonar head (on both VDSL and Ethernet). If using with an
existing IT infrastructure (i.e. the sonar head is located on the other side of a network
switch) then it will be necessary to construct a cable that does not connect to the
power output. Tritech International Ltd can provide such a cable.
Port J is for connection to an Ethernet infrastructure and it carries data from all of the
connected sensors on the Hub (including data from the DE-9 ports and timestamping
data generated by the signal on the BNC port) and as such it should be connected to
a Gigabit Ethernet connection.
During operation the status of the three ports will be displayed on the front panel of
the Gemini Hub. The top row of LEDs are for Link Status - the LED is red for
receive and green for transmit. The bottom row is for link speed and is as follows:
Port J
Port K & L

ORANGE = 100Mbit·s
GREEN = 1000Mbit·s
Shows link speed of internal connection between VDSL and
Ethernet, if dark or erratic this may indicate an internal fault with
the Hub.
