Figure 1-19
Operation with ROV - Subsea bottle configuration
If a standard ethernet connection is available through the ROV, untick Enable Serial and set
Adaptor to Ethernet.
If using serial communications direct to the U41 bottle or through a ROV multiplexing system,
tick Enable Serial, then specify protocol and baud rate using Mode and Speed (bps).
If using Eddyfi supplied subsea umbilical cable direct from Topside Unit to U41 subsea bottle, set
Adaptor to Ext. Ethernet.
Note: If you intend to connect directly to the ASSIST PC, i.e. not via the Topside Unit, using
standard Ethernet, then select DHCP Server as the IP Mode as the last configuration change
here.
To apply the changes, press the Green Arrow button. This will close the dialogue, restart the U41
bottle and show the Instrument Connection dialogue once again. There will be a delay before
the U41 instrument reappears in the dialogue.
If the Topside Unit has already been configured with matching serial protocols, after another
delay, a second ‘U41 – Serial’ instrument connection method will appear similar to that shown
in the dialogue below.
