Do I need a junction box for the MRU Marine?

The MRU Marine uses a custom 16-wire cable with Lemo connectors.

The 16 wires provide full flexibility for both Ethernet, RS-232, RS-485, PPS time sync and Aiding input.

You have 3 options for the connection:

  1. Pigtail cable only, that you terminate at your end.
  2. Junction box V2, that has standard connectors on the outside and uses a Lemo cable with connectors on both ends (Male for MRU side & Female for JB side)
    1. Lemo connector (for MRU connection)
    2. RJ45 (for Ethernet)
    3. Power input
    4. DB-9 connector for Time Sync
    5. DB-9 connector RS-485
    6. DB-9 connector for RS-232
  3. Junction box V3:
    1. Closed JB which is IP-68 rated and has 3 cable glands
    2. Ethernet connector inside for test and configuration use
    3. Termination blocks inside for all connections
    4. Pigtail cable for connection to MRU side
    5. This junction box can be used with both MRU Marine and MRU Marine SW
    6. The JB V3 has analog outputs, both Volt and Current, included
