Chapter 2. Getting Started Chapter 2. Getting Started Welcome to Eddy! This chapter includes Eddy series overview, main and distinctive features, package contents for each product, and application fields. 2.1 Overview There are 4 modules in Eddy-Serial Series; Eddy-CPU, Eddy-S1/Pin, Eddy-S1/DB9, and Eddy-S1/DB9PoE. Each module includes default applications for serial and LAN communication, and supports plug-andplay features.
Chapter 2. Getting Started ◆ Eddy-S1/Pin RJ-45 Ethernet port is included to provide direct connection to network. For serial communication, RS232 only or RS422/485 combo interface is available. In the combo module, RS422/485 setting can be adjusted with software, using web interface. Acceptable external power input ranges from 3.0 to 5.5V through pin headers. Please check labeled input voltage on top of the module before supplying power. Improper voltage feed may damage the module.
Chapter 2. Getting Started ◆ Eddy-S1/DB9-PoE This module can operate as a powered device (PD), which accepts power input from the twisted pair Category 5 Ethernet cable as specified in IEEE 802.3af Power-over-Ethernet (PoE) standard. With an auxiliary 5V DC power jack, power supply can be automatically channeled to 5V adaptor when PSE (Power Sourcing Equipment) is out of order. Seamless power supply is guaranteed. PSE power can be used again when the PSE resumes to normal operation.
Chapter 2. Getting Started ◆ Eddy Development Kit (Eddy DK) Eddy Development Kit (Eddy DK) helps programmers to test and customize their own Eddy applications easily, with 1 piece of Eddy-S1/Pin module included in the package. The kit includes evaluation board, all necessary connectors, and programming environment with documentations and guidelines. Please refer to Programming Guide included in the Development Kit for detailed information on the DK.

Chapter 4. Integration Chapter 4. Integration This chapter explains how you can make Eddy to communicate. It deals with LAN and pin header connection guides for Eddy to operate together with the target serial device. Follow these steps to connect Eddy to the device and network. 4.1 Connection Guide 1) LAN In order to connect Eddy to network, you need to use RJ45 Ethernet port. It supports both 10Mbps and 100Mbps Ethernet connection (auto-sensing).
Chapter 4. Integration 4.2 First-time Bootup First of all, please make sure the power input you supply to the module is corresponding with the Eddy model that you have. If an appropriate power input has been successfully supplied, Eddy will power on and start booting. For those models that require power input through pins (this will leave out DB9 models), you can notice that there are two Power In pins per serial port.
Chapter 4. Integration 4.3 Connecting to Eddy with IP address In order to view current Eddy’s settings or modify them, you need to make a Web or Telnet connection to Eddy. IP address is required information to make a connection. There are two ways you can know the current IP address of Eddy. First is to use a built-in, alias IP address of “10.10.1.1”. Second is to use “Detector” application provided in the Utility & Documents CD. This application allows searching for Eddy modules on the network.
Chapter 4. Integration ◆ Factory default alias IP address: 10.10.1.1 In case you configure Eddy to use DHCP to obtain an IP address automatically, you might find it hard to know the IP address to connect to. To provide users with an easier way to know the current IP address, Eddy has a fixed alias IP that is always accessible. Use the address below whenever you cannot find out Eddy’s IP address.
Chapter 4. Integration After running Detector, click Search button on the top-left to display all Eddy modules on the network. Select the module that you would make a connection to, and click Telnet or Web to connect to the module via Telnet or Web, respectively. Figure 4-3 Detector Layout If Eddy module is not on the same network as the PC you are working on, use “IP Configure” button to temporarily assign an IP address that you would like to make a Web or Telnet connection to.
Chapter 4. Integration 4.4 Eddy-S2M/Pin’s MCI & USB Host Port The following contents outline the usage of Eddy-S2M/Pin’s MCI & USB Host Port. Using MCI slot MMC and SDCards can be used through MCI slot. Please note that MCI and SDCard must be inserted before power is induced to Eddy-S2M/Pin module. MMC or SDCards are automatically recognized as a new disk space in " /tmp/mmc " folder. If memory card is not inserted to the MCI slot, " /tmp/mmc " folder will not be created.
Chapter 4. Integration recognized as /dev/sdb1, /dev/sdc1, /dev/sdd1…. Each device must be mounted for proper use. Following displays an example of two USB memory stick connection with a hub.

Chapter 5. Configuration via Web Menu Default Descriptions configuration, please refer to Chapter 3. Hardware Description. Select the operation protocol, which the serial port would use. ▪Disable Do not use this port. ▪COM Use the serial port of Eddy as the COM ports of Windows 2000/XP/2003/Vista operated PC. ▪TCP Server Eddy works as a socket server, waiting for the client connection on the network. Socket number for awaiting connections can be set in ‘Local socket port’ field.
Chapter 5. Configuration via Web Menu Default Descriptions Local Socket Port 4001 Set the socket number for the port. TCP server and UDP server operation mode makes use of this port for awaiting network socket connections. Port Alias Port1 Port alias name for convenience. 16 Characters at maximum. Baud Rate 9600 bps Set communication speed.
Chapter 5. Configuration via Web Menu Default Descriptions This needs to be set when consecutive data from the given serial port needs to be transmitted to socket at once. If 100 bytes of character string are to be transmitted from the serial device and bypass is set to Disable, Eddy waits until the entire 100 bytes are received. The maximum size to be transmitted at once is 1500 bytes.
Chapter 5. Configuration via Web 5.5 GPIO Settings Configure operation mode and value for each Programmable I/O pins. Eddy includes GPIO pins that output 3.3V or detect 3.3V signals. Eddy-CPU has 16 pins, Eddy-S1/Pin has 4 pins, but Eddy-S1/DB9 and Eddy-S1/DB9-PoE models do not have any GPIO pins. You can detect either any 3.3V signals from external device, or output 3.3V signal to the external device.
Chapter 5. Configuration via Web Figure 5-6 Eddy-CPU - GPIO Settings Page Table 5-5 Main features for GPIO Settings Menu Mode Value Default Descriptions Output Set current pin’s I/O mode.
