INTRODUCTION
This manual describes the operation and use of the C&H Model EM405-8 Ethernet M-Module
Carrier/LXI Bridge (Part Number 11029380). This instrument is one of a number of M-Module
carriers provided by C&H.
Contained within this manual are the physical and electrical specifications, installation and
startup procedures, functional description, and configuration and programming guidelines to
adequately use the product.
Software drivers for an installed M-Module may be provided by the M-Module manufacturer.
Some drivers may require modification to operate correctly with the communication protocol and
the addressing methodology used by the EM405-8. To support initial operation and application
software development, C&H provides a software application called Interactive Mezzanine
Control (IMC). The application provides immediate access and control of any M-module
residing on an EM405-8. IMC can be downloaded from the support section of C&H’s website
www.chtech.com.

1.0 GENERAL DESCRIPTION
The EM405-8 easily bridges up to eight (8) standard M-Modules to a LXI system or typical
Ethernet (LAN) network. The carrier providesfull access to the M-Module I/O space via the
standard TCP/IP networking protocol. LXI compliance provides a standard method of device
discovery, easy configuration through an intuitive web interface, and a standard IVI driver for
communication with the EM405-8 controller.
On the -0001 version, M-Module triggers are also fully supported allowing them to be connected
to any other installed M-Module or to an external device. Both TTL and LVDS signal levels are
supported. Please note that the triggers have currently not been approved as LXI compliant.
Use should be limited to non-LXI applications. 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 EM405-8 carrier, visit the
Support section on C&H’s website (www.chtech.com).

1.1 PURPOSE OF EQUIPMENT
The EM405 easily interfaces a VITA 12-1996 standard M-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-
Modules are available from numerous manufacturers.
WARNING: This product is not designed for use in explosive environments.

Notes:
1. Several milliseconds of overhead and latency occur on each command issued. The effect of this
overhead and latency is reduced by transferring large amounts of data with a single block read
command. Maximum read throughput is achieved by reading >4K bytes of data from a FIFO type
register on an M-Module using the Block Read command. Host software may vary and can limit the
maximum throughput.
2. The maximum number of bytes that can be written in a single block write command is 1024.
3. Ethernet is a non-deterministic communications interface. Realized throughput may be significantly
degraded by network activity or other factors that may affect network performance.
4. TLVL and TIMP refer to register bits in the TTL Trigger Control register. Refer to section 4.6.5.

1.3 Electrical
The EM405-8 can be operated from AC or DC power. The AC input accepts an industry
standard IEC 320-C13 power cord and automatically accepts an AC level between 85 and 265V
(47-63Hz). The power ON/OFF switch serves as an overload protection device. Toggling the
switch through the OFF position and back ON will reset the mechanism. The AC power is
converted to +48VDC for internal usage. Alternatively,the EM405-8 can be powered directly
by an external +48VDC (nominal) power supply. The external connector mates to a 5-pin
circular DIN male connector. See Appendix A for connector pin outs. The +48VDC power is
subsequently converted to +5V, +3.3V, +12V, and -12V to be used by the internal logic and M-
Modules.
Isolated and filtered +5V, +12V, and -12V supplies are provided to each M-Module position. In
addition, each position has separate power-off reset-able breakers for each voltage level supplied.
If a fault occurs, power must be removed from the EM405-8 before the breaker will reset. The
breakers are rated at 2.5 amps for the +5V power and 1.25A for the +12V and -12V power. This
allows usage of M-Modules that exceed the ANSI/VITA Std. 12-1996 specification for power
consumption;however, the total M-Module power consumption is limited to 8A for the +5V
supply and 1.6A each for the ±12V supplies.The ANSI specification allows a maximum of 1A
for the +5V supply and 200mA each for the ±12V supplies for a single M-Module.
1.4 Mechanical
The EM405-8 is contained in a 19 inch rack mount 1U high metal chassis with an outside
dimension of 19.0 inches wide by 12.2 inches deep by 1.72 inches high. A series of fansprovide
forced air for cooling the M-Modulesand the carrier electronics. The unit weighs approximately
9lbs with no M-Modules installed.
1.5 Environmental
The environmental specifications of the module are:
Operating Temperature: 0C to +60C*
Storage Temperature: -40C to +75C
Humidity: <95% without condensation
* The forced air cooling is designed to allow a maximum 20C temperature rise for
installed M-Modules. In other words, with eight M-Modules operating at full
dissipation (10W each), the M-Modules’ temperature can only be maintained within
20C of the ambient air inlet temperature. Installed M-Modulesmay differ in
environmental specifications. Refer to individualM-Module’s documentation for more
information.
