Page 11: Installation
If damage exists, report immediately to C&H. 2.2 HANDLING PRECAUTIONS The components used in the EM405D 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 12: Figure 3. M/Ma Configuration Diagram
Applying power to a misaligned module can damage the M-module and carrier. Re-assemble the EM405D by first sliding the carrier into the enclosure. Be careful to align the edges of the carrier with the guide rails of the enclosure. Improper alignment will cause the back panel component to not align with the back panel cutouts. -
Page 13: Functional Description
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. A simplified functional block diagram is shown in Figure 4. -
Page 14: M-Module Interface
2.5mm power jack connector or through pins on the 9-pin DSUB connector. 3.2 REAR PANEL The rear panel of the EM405D contains a +12V power input connection, an Ethernet connection or wireless antenna and a 9-pin DSUB connector that provides connection to M-module trigger lines and an alternate power input connection. -
Page 15: Front Panel
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. -
Page 17: Operating Instructions
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 EM405D may have a different IP address assigned each time it is powered on or connected to the network. For the wired EM405D, DHCP is automatically enabled if the IP address is set to 0.0.0.0. -
Page 18: Subnet Mask
The default port number for standard module access is: 10001 4.2.5 Wireless Settings Wireless EM405D’s have other settings that must be configured for the carrier to work on a wireless network. Network Mode: A wireless network can operate in one of two modes, infrastructure or ad-hoc. -
Page 19: Performing The Configuration - Wired Ethernet
4.2.6 Performing the Configuration – Wired Ethernet There are two ways to configure the wired version of the EM405D: a web-based interface and a Telnet interface. Both ways work equally as well and the choice of which to use is based solely on the user’s preferences. -
Page 20: Wed-Based Configuration
To configure the device through either the web-based interface or the telnet interface, the EM405D must be connected to a network and have a valid IP address known to the user. This creates an obvious dilemma. How do you configure a device via the network if it is not configured for the network? The EM405D provides a method to overcome this dilemma using a process sometimes referred to as address “gleaning.”... -

2) Create an entry in the host computer’s ARP table using the intended temporary IP address and the hardware address of the EM405D found in step 1. To perform this action on a Windows-based host, open the command prompt and type (the IP address can be any available address on your network and xx-xx-xx is the last three numbers in the unit’s... -
Page 22: Wed-Based Configuration
4.2.7.2 Restoring Factory Defaults Similar to the wired version, the wireless version of the EM405D has a dilemma in which the carrier must be connected to a network in order to configure its network properties. The dilemma is made worse in the wireless version by the fact that there is no physical connection to... -
Page 23: Communicating With The Carrier And M-Modules
The EM405D uses a simple binary command structure to communicate with the host software. The commands allow the user to either write or read registers residing on the EM405D or on each M-module. By writing registers residing on the EM405D, the user can identify the module, perform device configuration, and receive status. - Page 24 M-module itself. Once any of the above status codes are returned, the EM405D will set the Reset Error (RERR) status bit in the EM405D Reset Error and Manufacturer ID register (refer to section 4.3.5 for details on this register) and cease responding to further commands except the Read Data and Write Data commands to the Reset Error and Manufacturer ID register.
-
Page 25: Write Data Command
4.3.2 Write Data command The Write Data command writes data to an EM405D 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. -
Page 26: Block Access
The EM405D firmware will execute the command by reading or writing a block of data the size of the block size parameter, starting from the starting address and ending at:... -
Page 27: Block Write Command
Example 4: Read 32 words starting at address 0x0 followed by 32 words starting at address 0x80 starting address = 0x0 block size = 32 number of blocks = 2 address increment = 128 4.3.4.1 Block Write command The Block Write command writes a block of data to an M-module. A maximum of 1024 bytes can be written in a single command. -
Page 28: Block Read Command
4.3.4.2 Block Read command The Block Read command reads a block of data from an M-module. Unlike the block write command, block read does not have a restriction on the number of bytes that can be read with a single command. The number of bytes read in any given command is equal to: number of bytes = number of blocks * block size * word size The block read command consists of nine command bytes. -
Page 29: Em405D Configuration/Status Registers
4.3.5 EM405D Configuration/Status Registers The EM405D contains a set of registers that are used to identify the carrier, configure the carrier, and retrieve status from the carrier. These registers are independent of the M-modules residing on the board. Table III summarizes the register map. Bit level details of each register can be found in Figure 7. -

The carrier’s external trigger lines can be accessed at the 9-pin DSUB connector on the back panel of the EM405D. Refer to Appendix A for pin-out details of the 9-pin DSUB connector. The input trigger line has a software configurable threshold and input impedance. The input threshold is configurable using the TLVL bit in the Reset &... -
Page 33: Fan And Temperature Control
The EM405D contains an on-board temperature sensor placed near the M-module positions. The current temperature inside the EM405D case can be determined by reading the Fan & Temperature Control register of the EM405D. The TEMP field inside this register represents the current temperature as read by the temperature sensor. -
