KODEN, MRO-105 KEYBOARD FOR MDC-2910P/2920P

The KODEN MRO-105 Keyboard is a dedicated external operation unit designed specifically for use with KODEN MDC-2910P and MDC-2920P series marine radar systems. These radar systems are often “black box” configurations, meaning the main processing unit and display are separate, and the MRO-105 provides the primary user interface for controlling the radar’s functions.

Core Function and Purpose:

The MRO-105 keyboard serves as the human-machine interface (HMI) for the KODEN MDC-2910P and MDC-2920P radars. It allows mariners to interact with the radar system, adjust settings, control its various functions, and ultimately interpret the radar display for navigation and collision avoidance. Without this keyboard (or an equivalent control unit), operating the radar would be impossible.

Technical Specification

General:

Product Type: Radar Control Keyboard / Operation Unit
Compatibility: Exclusively designed for KODEN MDC-2910P and MDC-2920P series marine radar systems (specifically the processor units like MRM-105P, MRM-205P).
Interface: Dedicated cable connection to the radar processor unit. (Likely a proprietary serial or Ethernet-based connection for control signals).

Physical & Environmental:

Dimensions (Approximate):
- Width: Typically around 300 – 350 mm (11.8 – 13.8 inches)
- Height: Roughly 100 – 150 mm (3.9 – 5.9 inches)
- Depth: Around 200 – 250 mm (7.9 – 9.8 inches)
- Note: Exact dimensions can vary slightly, refer to the specific radar system’s installation manual.
Weight (Approximate): 1.5 – 2.5 kg (3.3 – 5.5 lbs)
Construction Material: Durable marine-grade plastic/metal, designed for bridge environments.
Color: Typically dark grey or black.
Key Illumination: Backlit keys for night operation.
Trackball/Pointing Device: Integrated trackball with associated click buttons (often illuminated with two-color LED for night operations, e.g., red/green).
Mounting: Designed for flush-mount or desk-top installation on a bridge console.
Operating Temperature: $- 1 5^{\circ} C$ to $+ 5 5^{\circ} C$ (typical for marine bridge equipment).
Storage Temperature: $- 2 0^{\circ} C$ to $+ 7 0^{\circ} C$ (typical).
Water Protection: IPX5 or equivalent (Protected against jets of water from all directions; typical for bridge consoles, not intended for direct spray).
Humidity: 95% at $4 0^{\circ} C$ (non-condensing).

Electrical:

Power Supply: Power is typically supplied directly from the radar processor unit via the interface cable. It does not usually have its own independent power input.
Power Consumption: Minimal, typically integrated into the overall radar system’s power consumption.

Controls & Interface Elements:

Dedicated Function Keys: For Range, Gain, STC, FTC, EBL, VRM, Display Mode, ARPA/ATA functions (Acquisition, Target Trail, Vectors), AIS, Plot, Mark, etc.
Menu Navigation Keys: Arrow keys, Enter, Esc.
Numeric Keypad: For data entry.
Programmable Function Keys: F1, F2, etc. (user-configurable).
Power On/Off button
Brilliance Control: For display and key illumination.

Certifications & Compliance:

Compliant with relevant international maritime standards (e.g., IEC 60945 for marine navigation and radiocommunication equipment, IMO performance standards for radars). Its compliance is usually part of the overall radar system’s certification.
