System Hardware Setup
Overview
The functional connections required for both diver and ROV operations are similar with the main
dierence being the umbilical used between the topside unit and subsea bottle: the diver unit
always uses the Eddy supplied 150m subsea umbilical whereas the ROV system may use either
the Eddy umbilical or use the ROV umbilical, as required. The connections are shown in block
diagram form below:
Figure 1-1 System hardware connections

System Overview
4 | www.eddy.com
Setup for Diver
The basic connections and setup procedure to congure the system for diver deployment is
shown below:
Figure 1-2 Diver setup
1. Ensure all mains switches are OFF.
2. Connect the topside unit to the mains supply using the RCD protected lead. If the local
supply is 230Vac then the included transformer will be required.
3. Connect the computer to the U41D topside unit, using the Ethernet cable. If the
computer needs to be powered from the mains supply, instead of running from the
internal battery, connect the mains lead to the 110V output connector on the topside
unit. For more advanced connection options, see Conguring the communications on
page 8.
4. Connect the test and integration deck cable to the topside unit and connect the main
umbilical(s) to the other end of the test umbilical. Note that up to 3 main umbilicals may
be connected in series depending on requirements.
5. Connect the main umbilical(s) to the subsea unit.
6. Connect the probe(s) to be used to the U41 subsea unit. Ensure that any probe connector
which doesn’t have a probe connected to it is tted with a blanking plug. Deploying the
bottle subsea with an exposed connector will cause severe damage to the unit.
7. Test the main cable RCD by turning ON the mains supply to the lead (with the topside
unit still switched OFF). Press the Reset button and verify that the red indicator is
showing. Press the Test button and conrm that the red indicator is removed. Press the
Reset button again and check that the red indicator reappears and remains. If this does
not function, or if during operation the RCD trips repeatedly, suspend all operations, turn
o mains supply and seek specialist advice.
8. Check to insure the 110v indicator panel is illuminated.
9. Turn on the power to the U41 system by pressing the power switch on the topside unit
panel.
10. Test the safety trip on the topside unit. Press the Reset button and verify that the blue
indicator on the power switch is showing. Press the Test button and conrm that the blue
indicator is removed and the red fault light is displayed. Press the Reset button again and
check that the red fault light is extinguished and the blue power button light reappears
and remains. If this does not function, or if during operation the safety trip trips
repeatedly, suspend all operations, turn o mains supply and seek specialist advice.
11. The subsea bottle will take approximately 20 seconds to initialise following the safety trip
tests. Switch on the computer and start the ASSIST™ software.

12. From the Backstage screen, press the Connect button. Select the instrument from the
available list and press the Connect button on this panel. For more advanced connection
options, see Conguring the communications on page 8
13. Test the correct functioning of the system by performing function checks on all probes
connected to the bottle.
Setup for ROV
There are two main setups for deploying U41R by ROV. The rst uses the Eddy umbilical and
the subsea bottle is electrically separate from the ROV for its power and communications. An
example of this deployment is shown below:
Figure 1-3 ROV setup
In this example the same general setup as used for the diver unit is used, see Setup for Diver on
page 4
The second main method is where the subsea bottle takes its power and communications from
the ROV itself.
Figure 1-4 ROV setup - power and communication taken from ROV

System Overview
6 | www.eddy.com
Figure 1-5 ROV Connections
1. Decide on the communications protocol to be used through the ROV system.
2. Ensure all mains switches are OFF.
3. Connect the topside unit to the mains supply using the RCD protected lead. If the local
supply is 230Vac then the included transformer will be required.
4. Connect the computer to the U41D topside unit, using the Ethernet cable. If the
computer needs to be powered from the mains supply, instead of running from the
internal battery, connect the mains lead to the 110-120Vac output connector on the
topside unit. For more advanced connection options, see Conguring the
communications on page 8.
5. Connect the test and integration deck cable to the topside unit and subsea bottle.
6. Test the main cable RCD by turning ON the mains supply to the lead (with the topside
unit still switched OFF). Press the Reset button and verify that the red indicator is
showing. Press the Test button and conrm that the red indicator is removed. Press the
Reset button again and check that the red indicator reappears and remains. If this does
not function, or if during operation the RCD trips repeatedly, suspend all operations, turn
o mains supply and seek specialist advice. Note that in this conguration, the topside
unit does not provide DC power to the instrument via the umbilical, this instead comes
from the ROV supply.
7. Check to insure the 110v indicator panel is illuminated.
8. Turn on the power to the U41 system by pressing the power switch on the topside unit
panel. If the blue indicator light in the switch does not light, press the reset button in the
Safety Trip area.
9. The subsea bottle will take approximately 20 seconds to initialise. Switch on the computer
and start the ASSIST™ software.
10. Congure the communications between topside unit and subsea bottle to match the
protocol decided in step 1. See Operation with ROV on page 11. Check that the subsea
bottle can be connected to using the new protocol.
11. Power down the topside unit, remove the deck cable and secure the subsea bottle to the
ROV.
12. Temporarily connect the free end of the Eddy supplied subsea communications whip to
the ROV subsea cable, supplied by the ROV team. The power wires and the
communication protocol wires, decided in step 1, must be connected.
13. Power up the ROV port and test that the correct power voltages are present on the
bottle end of the Eddy supplied subsea whip, see Umbilical on page 18 Power down
the port.

14. Connect the Eddy supplied subsea whip to the subsea bottle umbilical connector
15. Connect the Eddy supplied topside whip free end relevant communication wires to the
ROV topside integration port. See Connectors on page 24. Connect the other end to
the topside unit umbilical connector.
16. Connect the probe(s) to be used to the U41 subsea unit. Ensure that any probe connector
which doesn’t have a probe connected to it is tted with a blanking plug. Deploying the
bottle subsea with an exposed connector will cause severe damage to the unit.
17. Power up the topside unit and ROV port. Using ASSIST, attempt to connect to the subsea
bottle. If there is no connection, re-check the physical connections and, if using serial
protocols, try swapping Rx and Tx at one end of the ROV interface.
18. Once communications are established, function check the probe on the test plate to
ensure that data is passing reliably through the system.

Conguring the communications
Alternative LAN topologies
Connection of PC or laptop to U41 systems is usually via a standard RJ45 CAT5 style LAN cable
directly from the computer to the instrumentation. This is the default setup and conguration
is not normally required. However, if LAN conguration changes have been made since the
system was received, these may need to be undone for the original operation to function again.
Alternative congurations are available, providing benets such as using existing premises LAN
and enabling use of a single PC LAN port. The most common scenarios are shown below.
Figure 1-6 LAN topologies
Conguring these alternative networking scenarios diers between U41-D and U41-R systems.
The table below outlines the recommended settings.
Scenario System Topside Unit U41 Bottle
A U41-D --- DHCP Server
B U41-D --- DHCP Server
