What feature does the CNU-660/E contain for testing the BRU-61 carriage system?

The CNU-660/E is specifically designed to support the BRU-61 carriage system, and one of its key features is the built-in-test (BIT) cable. This cable enables operators to perform diagnostic tests directly on the equipment, allowing for immediate identification of any issues that may affect the functioning of the carriage system. By facilitating regular monitoring and troubleshooting, the BIT cable helps ensure the reliability and readiness of munitions systems.

While diagnostic software, a test console, and a simulation mode might be useful in various testing scenarios, they are not the primary built-in feature of the CNU-660/E intended for testing the BRU-61. The BIT cable's function directly aligns with the need for operational checks within the testing framework of the CNU-660/E, making it a vital component for effectively maintaining the integrity of the carriage system.
