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

1.3 Electrical The EM405D only requires a +12V DC power input. The +12V input is internally converted to the +3.3V power required by the carrier and the +5V, +12V, and -12V power required by the M- modules. A maximum of 30 watts is required to support the carrier and two M-modules operating at the maximum allowed power consumption. The maximum allowed power consumption for each M-module is 1A of +5V and 200ma each of +12V and -12V. The EM405D uses power-off resetable fuses on the inco

2.0 INSTALLATION 2.1 UNPACKING AND INSPECTION Verify that there has been no damage to the shipping container. If damage exists then the container should be retained, as it will provide evidence of carrier caused problems. Such problems should be reported to the carrier immediately as well as to C&H. If there is no damage to the shipping container, carefully remove the instrument from its box and inspect for any signs of physical damage. If damage exists, report immediately to C&H.

3.0 FUNCTIONAL DESCRIPTION 3.1 GENERAL The EM405D provides a mechanical and electrical interface between an Ethernet bus and up to two M-modules. It utilizes an embedded microcontroller to provide buffering and command translation between the Ethernet interface and the M-modules.

3.1.3 M-module Interface The M-module interface provides the mechanism for the microcontroller to access the M- modules. It is implemented using programmable logic that emulates a bridge between the microcontroller and the M-module bus. The logic also provides trigger configuration and control. 3.1.4 Power Conversion The +12V input power is converted to the +3.3V power required by the carrier and the +5V, +12V, and -12V power required by the M-modules. The input power can be suppl

3.3 FRONT PANEL The front panel of the EM405D contains two openings for access to the M-modules’ front panel connections and three LED indicators as shown in Figure 6. As mandated by the M-module specification, each M-module should provide a front panel connector containing the M-module I/O signals. The two openings on the EM405D’s front panel provide access to these connectors. The functions of the three front-panel LED indicators are: PWR: indicates that power is supplied to the

4.0 OPERATING INSTRUCTIONS 4.1 GENERAL The EM405D is controlled through the Ethernet interface using the TCP/IP protocol to carry a simple command structure to the module. The carrier contains a set of software controlled registers that allow the user to request status from the carrier, identify the carrier, and configure the carrier. All other M/MA controls are dependent on the specific M-module(s) that reside on the carrier. 4.2 CONFIGURING THE ETHERNET INTERFACE The Etherne

RECOMMENDATION The EM405D is an embedded device without an input device or display that can be used to determine the current configuration of the device. This can cause difficulties in determining at what IP address to access the module. For this reason, it is highly recommended, but not required, that the EM405D be configured to use a static IP address. 4.2.2 Subnet Mask The subnet mask defines the number of bits that are taken from the IP address to refer to the given network

of other tasks. In ad-hoc mode, wireless devices may communicate directly with each other and an access point is not needed. In this case, all devices on the network must be configured to use ad-hoc mode. The default network mode is: infrastructure. SSID: The Set Service Identifier (SSID) is a name given to a wireless access point to identify the access point on a wireless network. Most access points can be configured to periodically broadcast the SSID or to keep it private.

4.2.6.1 Wed-based Configuration To use the wed-based interface to configure the wired EM405D, open a Java enabled web browser and enter the device’s IP address as the web address to open. This will download and run a Java applet from the device allowing the user to make changes to the devices configuration. Navigate through the pages of the web interface making the necessary changes to the configuration. When finished, click on the “Update Settings” button to apply the changes. Note
