Description
Koden MDS-1103R radar PC system
Koden MDS-1103R is a radar PC system configuration listed with the 17in RB-804 scanner and 10m cable. A PC-based radar installation needs the radar hardware, computer environment, display arrangement, scanner, cable, power and navigation-data interfaces to be treated as one system. F&C Marine can help review the intended installation before supply so the correct MDS configuration and supporting equipment are identified.

Configuration and system matching
This listing identifies MDS-1103R with the 17in RB-804 and 10m cable. Related MDS-1100 versions use different scanner and open-array combinations, so the full model reference should be retained on quotations and vessel records. For a replacement or upgrade, record the existing scanner arrangement, cable route, power supply, computer or monitor installation and all data interfaces. Clear photographs of connectors and equipment labels can help establish what can be reused and what needs to be renewed.
PC radar installation planning
PC radar can make good use of an existing bridge display environment, but it requires careful planning. The computer and display must be suitable for the radar arrangement, and scanner cabling needs a protected route from the antenna position to the processing equipment. Service access and cooling around electronic equipment should be considered. Existing cables should only be retained after compatibility and condition have been confirmed, because water ingress, damaged plugs or previous modifications can create intermittent faults that complicate commissioning.
Power and navigation data
The radar installation also depends on stable power and correct navigation inputs. Supply wiring and protection should be checked for the actual equipment being installed. Where heading, position, speed, AIS or other vessel data is used by the radar, each required input should be identified in advance and tested during commissioning. A problem elsewhere in the data network can appear to be a radar fault, so the interfaces between systems should be treated as part of the job rather than as an afterthought.
Commissioning the complete system
Commissioning should include scanner operation, power under operating load, target presentation, display and control functions and the relevant navigation-data inputs. The radar should be checked in the configuration the vessel will actually use. Any warning, alarm or missing data should be resolved before handover. For a refit, comparing the completed installation with photographs and records from the old system is a useful way to confirm that no connection or external sensor has been overlooked.
Documentation and related guidance
For current Koden information, see Koden marine electronics. Use the applicable manufacturer manuals as the final reference for computer requirements, wiring, dimensions and setup. F&C Marine also provides a marine radar range, a Radar vs AIS guide and the Marine Electronics Knowledge Base for related installation and troubleshooting information.

Before ordering Koden MDS-1103R
Send the vessel type, existing radar details, photographs of the scanner and bridge equipment, cable information, supply voltage and the computer or display arrangement that will be used. Also identify any heading, GNSS or AIS information expected at the radar. If the project follows a fault, include symptoms and previous test results. F&C Marine can then help confirm compatibility, current availability and the likely accessories or installation work required before the equipment is ordered.
