    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 provides full 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.

    If damage exists, report immediately to C&H. 2.2 HANDLING PRECAUTIONS The components used in the EM405-8 are static sensitive. Damage may occur if proper static precautions are not taken. Installation of M-Modules should only be done at a properly grounded static free workstation.

  • Page 13: Removal Of M-Modules

    The module should slowly loosen itself from the carrier header pins. If the EM405-8 is completely full, a pointed prying bar may be required to help remove the first module. The point of the prying bar can be placed between the carrier header and the M-Module to loosen the connection as shown in Figure 4.

  • Page 15: Functional Description

    3.0 FUNCTIONAL DESCRIPTION 3.1 GENERAL The EM405-8 provides a mechanical and electrical interface between an Ethernet bus and up to eight M-Modules. It utilizes an embedded microcontroller to provide buffering and command translation between the Ethernet interface and the M-Modules. A simplified functional block diagram is shown in Figure 5.

  • Page 16: Ethernet Interface

    3.1.2 Ethernet Interface The Ethernet interface provides the physical and logical connection to the EM405-8 allowing remote control of the M-Modules. The EM405-8 provides a 10/100 Base-T Ethernet connection for communication purposes. The interface supports the TPC/IP protocol for control of the M- Modules.

  • Page 17: Front Panel

    3.2 FRONT PANEL The front panel of the EM405-8 contains eight openings for access to the M-Modules’ front panel connections as shown in Figure 6. Below each opening is an LED indicator that indicates an access to that M-Module. The LED will illuminate temporarily each time the module is accessed by the host software.

  • Page 18: Rear Panel

    3.3 REAR PANEL The rear panel of the EM405-8 contains connectors for the Ethernet and USB interfaces, TTL and LVDS triggers (-0001 versions only), and AC or DC input power. An AC power switch/breaker is available on the far right side and a LAN reset access hole is available below the LAN connector.

    Figure 8. Web Home Page 4.4 CONFIGURING THE ETHERNET INTERFACE Network configuration of the EM405-8 is performed through the LAN Configuration page of the web interface. To view the LAN Configuration page, select the LAN Configuration link from the navigation menu found on the left side of all EM405-8 web pages.

  • Page 21: Tcp/Ip Mode

    DHCP: The Dynamic Host Control Protocol (DHCP) allows the module to dynamically retrieve an IP address from a DHCP server at power-up. If DHCP is used, the EM405-8 may have a different IP address assigned each time it is powered on or connected to the network. DHCP requires that another device on the network is acting as a DHCP server.

  • Page 22: Ip Address

    The subnet mask defines the number of bits that are taken from the IP address to refer to the given network subsection. The subnet mask allows Ethernet based networks to be separated into various subnets. The EM405-8 should be in the same subnet as the controlling PC or router. The default subnet mask is: 255.255.255.0 4.4.4 Gateway...

    TCP protocol layer and therefore special protocols are not required. Regardless of the encapsulating protocol, the messages and data that the EM405-8 uses is based on a simple binary command structure. The commands allow the user to either write or read registers residing on the EM405-8 or on each M-Module.

    Module, or more serious hardware problems with the M-Module itself. If any of the above status codes are returned, the EM405-8 will set the Reset Error (RERR) status bit in the EM405-8 Reset Error and Manufacturer ID register (refer to section 4.6.5 for details on this register).

  • Page 28: Write Data Command

    4.6.2 Write Data command The Write Data command writes data to an EM405-8 control register or to a register residing on an M-Module. The command consists of seven bytes including the command-id, the module to which the data should be written, an address space selector, the access width, the address, and two data bytes.
