This four-slot MMS system provides the source capabilities necessary to meet BRAT replacement requirements. The module is also available in a single “U” rack mount option. The module utilizes the ATTI slot-0 service to enable remote programming. A GUI is provided to allow manual operator control. This system is a target product for Mil-Aero and DoD customers faced with reduced support equipment modernization budgets and legacy MMS systems requiring sustainment. Eliminates the need to replace MMS chassis or find rack space to incorporate a new chassis or framework. Does not require any micro-code overhead or complex development.
