Dispense Control Unit (DCU)
It is the main unit providing the control of dispense function. Each Dispense Control Unit can be connected up to 4 dispensers. It initiates dispensing based on commands received from the System Control Unit and executes dispensing in accordance with the sequence de ned by the selected dispense program. Its main functions are:
- Execution of dispensing by providing ring current to the selected cartridge(s)
- Misfire detection and correction
- Detection of magazine identification codes
- Inventory monitoring and detection of cartridges in magazines
- Built-in Test (BIT)
System Control Unit (SCU);
System Control Unit provides the necessary visual interface for the pilot, as well as being the main control unit which manages dispense programs and allows integration with other on-board systems. Its main functions are:
- Man-machine interface
- Storage/zeroize of Mission Data File (MDF)
- Displaying inventory and status information
- Initiation and monitoring of dispensing
- Operating mode selection
- Communicating with Dispense Control Unit and other on- board EW systems
- Manual activation of dispensing and Jettison
- Error, misfire and event recording
- Built-in Test (BIT)
Dispenser Base
It allows magazines to be easily integrated onto the platform. Dispenser Base includes 60 contacts which provide the electrical connection between the Dispense Control Unit ring lines and the electrical impulse cartridges (squibs) of the chaff/ are decoys. It detects magazine identi cation codes which provides the con guration information de ning the types of decoys loaded into the magazine. Dispense Control Unit accomplishes inventory detection by reading the magazine identification codes and relaying this information to the System Control Unit.
Magazine
Each magazine can be loaded with 30 decoys of 1”x 1”x 8” type or 15 decoys of 2”x 1”x 8” type. The helicopter versions of the magazines are produced in 3×10 format, while the fixed wing versions are produced in 6×5 format with housings. Magazines are made of durable and lightweight composite materials.
