JRC NDC-2000-M2 Processor Unit

JRC NDC-2000-M2 Marine ECDIS Processor Unit (with Security Dongle)

The JRC NDC-2000-M2 is a processing unit manufactured by Japan Radio Co., Ltd. (JRC) to serve as the core central computer for the JAN-2000 ECDIS and JAN-2000-CON Conning Display navigation systems. Built specifically for demanding maritime environments, the NDC-2000-M2 processes critical navigational sensor feeds—including GPS/DGPS, Gyrocompass, Speed Log, Echo Sounder, AIS, and ARPA radar tracking—delivering vector (S-57/ENC, C-Map) and raster (ARCS) chart rendering in real time.

This specific unit includes the hardware-locked security dongle (Dongle No. J9745) required for system decryption, software authentication, and chart service authorization. Housed in a heavy-duty, corrosion-resistant chassis built to IEC 60945 Class A standards, the NDC-2000-M2 delivers uninterrupted high-speed computation for commercial vessel navigation consoles.

Frequently Asked Questions

What is the primary function of the JRC NDC-2000-M2 processor?

The NDC-2000-M2 serves as the core computer and sensor aggregation hub for JRC marine systems, including the JAN-2000 ECDIS and JAN-2000-CON Conning Display. It processes navigational sensor inputs and renders chart databases onto bridge displays.

Can the NDC-2000-M2 operate without the J9745 hardware dongle?

No. The system requires the hardware security dongle (such as Dongle No. J9745) connected to the dedicated USB/Parallel port. Without this recognized license key, the ECDIS operating kernel will not complete boot authorization, restricting the operator from accessing navigational chart functions.

What is the compass safe distance for the NDC-2000-M2?

The unit has a verified compass safe distance of 4.6 meters for a standard magnetic compass and 1.0 meter for an emergency/steering magnetic compass. These clearance guidelines must be observed during bridge console layout design.

What should be checked if the unit fails to receive heading or GPS data?

First, verify that the NMEA 0183 / IEC 61162 line polarity (+ / – or A / B) is correct on the corresponding COM port terminals. Second, confirm that the sensor baud rate matches the port configuration (typically 4800 bps for GPS/log, 38400 bps for AIS). Finally, check that the cable shield is grounded only at the processor end to eliminate line noise interference.

Can an NDC-2000-M2 replace an earlier generation NDC-2000 unit?

Yes. The NDC-2000-M2 shares the same footprint, power supply inputs, and connector harness compatibility as standard NDC-2000 base models, making it a direct retrofit replacement for bridge maintenance and refit projects.
