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.
