Compliance

Hardware version

MDD400 v2.9 — Fabricated prototype — testing phase

Overview​

This page covers the regulatory and standards compliance posture of the MDD400 — CE, FCC, UKCA, RoHS/REACH/WEEE, ingress protection, and NMEA 2000.

The MDD400 is designed with reference to the standards and directives listed below. The device is currently in the prototype and pre-certification phase — it is designed-for compliance with these requirements, with independent test reports pending. Formal testing and certification will be conducted on production-representative units prior to commercial release (targeted for v2.10).

CE Marking (EU)​

The MDD400 is intended to carry the CE mark under the following EU directives:

  • Electromagnetic Compatibility Directive 2014/30/EU — radiated and conducted emissions, and immunity testing to CISPR 32 / EN 55032 (Class B) and EN 55035.
  • Low Voltage Directive 2014/35/EU — the device operates below 50 V DC and is classified as low voltage equipment.
  • RoHS Directive 2011/65/EU — all components and PCB materials sourced with RoHS certificates of compliance; lead-free ENIG surface finish and solder process.

Pre-compliance emissions and immunity testing will be performed using the final enclosure and firmware before Declaration of Conformity is issued.

FCC (United States)​

The MDD400 is designed to meet FCC Part 15, Class B requirements for unintentional radiators. A formal emissions test report will be prepared by an accredited test laboratory. The device will be labelled in accordance with 47 CFR §15.19. Testing includes radiated and conducted emissions using the final production enclosure and firmware build.

UKCA (United Kingdom)​

CE design targets are equivalent to UKCA technical requirements. UKCA conformity assessment and marking will be applied for UK market entry in parallel with CE.

RoHS / REACH / WEEE​

RegulationStatus
RoHS 2011/65/EU (amended by 2015/863/EU)Lead-free design; component CoCs to be collated
REACH SVHCNo intentionally added SVHCs above 0.1 % w/w; full SCIP submission on first sale
WEEE 2012/19/EUWEEE category 9 (monitoring and control instruments); registration required for EU/UK sales

Ingress Protection​

The enclosure targets IP65 (IEC 60529) — fully dust-tight, protected against water jets from any direction. Connectors are rated IP67 when mated. Third-party IP testing will be conducted during pre-certification on production-representative units.

NMEA 2000​

The MDD400 CAN physical interface conforms to ISO 11898-2 and is designed for use on NMEA 2000 networks:

  • The CAN front end is non-isolated: GNDREF is referenced directly to the NMEA 2000 bus ground (NET-C), the standard topology for a bus-powered node. (V2.9 replaced the earlier isolated ISO1042 transceiver + transformer with the non-isolated SN65HVD234DR.) The only opto-isolated interface on the board is the legacy serial path (GNDS).
  • Network power draw within NMEA 2000 allowed limits for LEN=1 and LEN=2.
  • M12 A-coded (Micro-C) 5-pin connector (J2) as specified by the NMEA 2000 physical standard.
  • PGNs assigned in accordance with MFD and general display categories.

Final NMEA 2000 certification will be coordinated with the National Marine Electronics Association (NMEA) prior to commercial release.
