Description
The YDK Technologies (formerly Yokogawa Denshikiki, established 1852) MKN020 Gyro Compass Connection Box is a high-performance connection unit tailored for the CMZ900 Gyrocompass series. Specifically engineered for use with the MKR050 repeater, this box ensures reliable signal transfer and system integration for accurate maritime navigation.
Replacing the older MKN019, the MKN020 features a robust plastic housing, making it lighter and more corrosion-resistant than the previous aluminum-cast version. The internal configuration has been simplified to a single RPT CPU board, eliminating the TERMINAL BD used in the earlier design. Despite the redesign, PCB mounting points remain compatible, making it easy to upgrade from MKN019 to MKN020.
Available in a range of configurations, the MKN020 supports both gland (-G) and plug (-P) connection types in sizes 15F, 20F, and 25F. This flexibility allows for seamless integration with different cable systems on vessels. Paint options include Munsell 2.5G7/2 and 7.5BG7/2, and nameplates can be ordered in Japanese & English or English only, ensuring localization preferences are met.
This connection box is also adaptable in terms of installation. It supports multiple mounting styles including horizontal brackets (-HB), horizontal stands (-HS), and tilting brackets (-TB). Signal types such as HEHDT, HCHDT, GPHDT, HETHS, HCTHS, and GPTHS are selectable using suffixes, which indicate the transmitted sentence type for connected navigational equipment.
Signal transmission is handled via serial ports, with support for 4800bps, 9600bps (default), and 38400bps baud rates. There’s also a /C option for Chinese nameplates, expanding accessibility for diverse fleets.
LED indicators on the box help operators monitor signal status, error detection, and zero-point calibration. Designed not only for the CMZ900B2 but for all CMZ900 models with MKR050, the MKN020 is an essential upgrade for ships requiring reliable and efficient gyrocompass integration.
