1.0 GENERAL DESCRIPTION

The EM405D Ethernet M-Module carrier provides complete Ethernet connectivity to up to two industry standard single-wide or one double-wide M or MA modules. The carrier provides full access to the M/MA module I/O space via the standard TCP/IP networking protocol. M-module triggers are also fully supported allowing them to be connected externally to a 9-pin DSUB connector or to an adjacent M-module. A simple command structure eases software integration and allows reset, identification, control, and configuration of the carrier and M-modules. For a complete list of M-modules compatible with the EM405D carrier, visit the mezzanine section of www.mezzanines.org, or www.vita.com.

1.1 PURPOSE OF EQUIPMENT

The EM405 easily interfaces a VITA 12-199x standard M/MA Module to a typical Ethernet network. The carrier allows the numerous functions available in the M-Module mezzanine format to be remotely located near the unit-under-test, easing many system integration issues. Over 100 M/MA modules are available from numerous manufacturers.
