OceanWorks initially delivered 14 SIIMs to NEPTUNE Canada in 2008 and 2009. The SIIMs (also know as Junction Boxes) are used to interface multiple science instruments to a single port on a node. The upgraded SIIM is a flexible, software configurable design with two key custom developments: a Variable Voltage Power Supply (VVPS), with a software selectable output voltage from 12VDC to 48VDC; and a Communication Selection Board, that will allow the software selection of either serial or Ethernet communications on each port. In addition, the SIIM serial ports have been upgraded to provide Pulse-per-Second (PPS) and Time-of-Day (ToD) signals using Precision-Timing-Protocol (PTP).
The upgrade allows for both the voltage and its communication protocol on the downstream ports to be changed by software without the need to open the pressure vessel. Since this change can be done in the lab or on the vessel the versatility of the SIIM is much improved allowing NEPTUNE to reduce operational and maintenance costs and reduce deployment risk by allowing common sparing of a single SIIM design rather than customizing a SIIM for each instrument platform.
