3.1.3.2.2 Signal Data Converter and Gun Mount MK 45 Mod 2 Interface

(Destroyer Modernization only)

The GM MK 45 Mod 2 requires eight separate interface types for control by the GCS.

These interface types are first generation in format and are not supported by the ACB12

LAN-based Interconnection Architecture. For this reason, the GCS will interface with the GM MK 45 Mod 2 through the use of a separate Signal Data Converter access unit which connects to the GCS Common Processing System (CPS) enclosures using Ethernet on the front end, and with the GM MK 45 Mod 2 using the eight required interface types on the back end.

To retain commonality of the GCS computer program in the gun interface area, all details of connecting to a GM MK 45 Mod 2 are isolated within the access unit. This allows the

GCS computer program to interact with the front end of the access unit as though communicating with a GM MK 45 Mod 4. The access unit translates GM MK 45 Mod 4 orders and controls bound for the GM MK 45 Mod 2 in terms of the interface types needed by the GM MK 45 Mod 2. Similarly, the access unit translates GM MK 45

Mod 2 status into the equivalent GM MK 45 MOD 4 format and passes this data to the

GCS computer program. The interface with the GM MK 45 Mod 2 then is really defined in two parts: the GCS CPS-to-SDC interface and the SDC-to-GM MK 45 Mod 2 interface. The GCS-to-SDC is defined in WS-35476. The SDC-to-GM MK 45 Mod 2 is based on WS-22537A, Interface Control Document for MK 160 Gun Computer System to

5-Inch 54-Caliber MK 45 Gun Mount, date February, 2010.

The EOSS interface shall be based on WS-35167B, Gun Computer System MK 160 Mod 11 to Electro-Optical

Sensor System MK 20 Mod 0 Interface Design Document, February 2010. The GCS shall have the capability to accept and display EOSS camera video.

3.1.3.2.4 GCS-to-Velocimeter Interface

The GCS shall provide setup, test and operation instructions to the Velocimeter. The

Velocimeter in return reports equipment status and projectile muzzle exit velocity measurements to the GCS. The interface from the GCS to the Velocimeter consists of two types of physical connection: Ethernet from the GCS CPS to the Gun Mount Control

Panel (GMCP) and RS-232 from the GMCP to the Velocimeter. The interface is defined in WS-32820A, Interface Design Specification for the Velocimeter MK5 Mod 0 and the

Gun Computer System MK 160 Mods 4 and Follow; 6 January 2003.
