MIL-188-114 interface specifications

Specification MIL-188-114 describes a data communications interface that uses
DB-25 connector or DB-37 connectors using balanced or unbalanced MIL-188-114
amplifiers for all circuits. The MSAM supports testing of MIL-188-114 circuits in asyn-
chronous or synchronous mode.
