Package Contents Your EDS4100 package includes the following items: One EDS4100 device server One DB9F-to-DB9Fnull modem cable One product CD that includes this User Guide, the Command Reference, and the Quick Start guide. A printed Quick Start guide Your package may also include a power supply.
3: Installation: EDS4100 Identifying Hardware Components Figure 3-1 shows the hardware components on the front of the EDS4100. Figure 3-2 shows the hardware components on the back of the EDS4100. Figure 3-1. Front View of the EDS4100 Figure 3-2. Back View of the EDS4100 The bottom of the EDS4100 (not shown) has a product information label.
3: Installation: EDS4100 Serial Ports The front of the EDS4100 has four male DB9 serial ports. These ports allow you to connect up to four standard serial devices: All four serial ports support RS-232 devices. See Figure 3-3 for pin assignments. Serial ports 1 and 3 also support RS-422 and RS-485 serial devices. See Figure 3-4 for pin assignments. All four serial ports are configured as DTE and support baud rates up to 230,400 baud. Figure 3-3.
3: Installation: EDS4100 Ethernet Port The back panel of the EDS4100 provides an RJ45 Ethernet port. This port can connect to an Ethernet (10 Mbps) or Fast Ethernet (100 Mbps) network. The Speed LED on the back of the EDS4100 shows the connection of the attached Ethernet network. The EDS4100 can be configured to operate at a fixed Ethernet speed and duplex mode (halfor full-duplex) or auto-negotiate the connection to the Ethernet network.
3: Installation: EDS4100 Reset Button The reset button is on the back of the EDS4100, to the left of the power connector. Pressing this button reboots the EDS4100 and terminates all data activity occurring on the serial and Ethernet ports. Physically Installing the EDS4100 Finding a Suitable Location Place the EDS4100 on a flat horizontal or vertical surface. The EDS4100 comes with mounting brackets installed for vertically mounting the unit, for example, on a wall.
3: Installation: EDS4100 The EDS4100 powers up automatically. After power-up, the self-test begins and Evolution OS™ starts. Note: These power-up methods can be used together to provide a redundant power source to the unit. 4. Power up all connected serial devices. Figure 3-7.

C: Networking and Security This chapter describes the following networking and security concepts as they relate to the EDS: SSH ⎯ described below. SSL ⎯ see page 159 Serial tunneling ⎯ see page 161 This chapter concludes with a description of modem emulation (page 164). SSH Like SSL, Secure Shell (SSH) is a protocol that provides secure encrypted communications over unsecured TCP/IP networks such as the Internet.
C: Networking and Security SSL Secure Sockets Layer (SSL) is an open-standard security protocol that provides privacy through encryption, server authentication, and message integrity. From its introduction in 1994, SSL has become the industry standard for securing e-commerce transactions over TCP/IP connections. And it is easy to see why. Imagine mailing a letter in a clear envelope that anyone could see.
C: Networking and Security When a Web browser accesses a domain secured by SSL, an SSL handshake authenticates the server and client, and establishes an encryption method and a unique session key. Once this handshake has been completed, the client and server can begin a secure session that guarantees message privacy and message integrity.
C: Networking and Security Tunneling Tunneling provides a way to create a connection between two serial devices across an untrusted network so the devices can share data. The sharing of information is achieved through a direct connection (or “serial tunnel”) between the two devices that encapsulates, authenticates, and encrypts the serial data into TCP packets and sends them across the Ethernet network.
C: Networking and Security Tunneling and the EDS Each EDS serial port supports two concurrent tunneling connections, Connect mode and Accept mode. These connections operate independently of the other EDS serial ports. In Connect mode, the EDS actively makes a connection. The receiving node on the network must listen for the Connect mode’s connection. By default, Connect mode is disabled. In Accept mode, the EDS listens for a connection. A node on the network initiates the connection.
C: Networking and Security Connect Mode has six variations: Disabled (no connection) Enabled (always makes a connection) Active if it sees any character from the serial port (makes a connection upon receiving any character) Active if it sees a specific (configurable) character from the serial port Modem emulation (controlled by modem commands) Modem control asserted (makes a connection when the modem central signal on the serial line becomes active) For the “any character” or “specif
C: Networking and Security The EDS observes the modem control inactive setting. To clear out data from the serial buffers upon disconnecting, configure the EDS to flush serial data (see Tunnel – Disconnect Mode Page on page 66. Packing Mode Packing mode takes data from the serial port, groups it together, and sends it out to nodes on the network. The groupings may be configured by size or by time intervals.
C: Networking and Security Command Mode The Modem Emulation’s Command mode supports the standard AT command set. For a list of available commands from the serial or telnet login, enter AT?. Use ATDT, ATD, and ATDP to establish a connection: +++ Switches to command mode if entered from serial port during connection. AT? Help. ATDT
Establishes the TCP connection to socket (/). ATDP See ATDT. ATD Like ATDT. Dials default connect mode remote address and port.C: Networking and Security (Since the remote port was not specified in the ATDT command, the remote port defined under Connect mode is used.) Entering ATDT 28.150 causes the EDS to assume the first two octets in the IP address and connects to the remote IP address 192.168.28.150, port 10001. Entering ATDT 150 causes the EDS to assume the first three octets and connects to the remote IP address 192.168.16.150, port 10001. Entering ATDT 28.
