Status on the IU in CPPM
Already purchased and delivered in CPPM :
1 IMM modem
1 Inductive cable
1 Inductive CTD (Seabird)
1 Currentmeter Aquadop (Nortek) + inductive interface (UIMM)
IU/CB communication
One 50m electric cable is foreseen
RS422 or 485 serial link is preferred to ethernet
Wet matable on the IU side (not on the CB side)
communication drivers have been ordered and will be tested in CPPM on a similar 50m electric cable with ODI connectics (lent by DT INSU)

12. Developpement in progress in CPPM

Status on the IU in CPPM
Developpement in progress in CPPM
1 – IU instrumentation implementation
 Inductive set up and test bench is operational in CPPM :
inductive modem management, communication with instruments via inductive line, etc
2 – IU mechanical structure
 Design of the IU anchor is under going
 Global mechanical specifications are under reflexion (deployment, …)

13. Evaluation of acoustic modem vs electrical cable solution
CB – IU status
Status on the IU in CPPM
On going :
Evaluation of acoustic modem vs electrical cable solution
Wait for the acoustic modem Albatross results
Albatross will be deployed at the beginning of june 2015
will be linked via one acoustic modem to the MII (connected in the same time than the 1rst DU on the Meust node)
- first tests were decevant but problems should have been resolved
Purchase of the first elements of the IU have been launched
(IMM, ICC, UIMM, instruments,
