2.2.3 Connecting To The Device Connect the serial data cable between the LS110 and the serial device. If necessary, supply power to the serial device attached to the LS110. Figure 2-4 Connecting a serial device to the LS110 2.3. Accessing Console Port There are two ways to access console port of the LS110 depending on whether the user is located at a local site or a remote site.
2.3.1 Using Serial Console 1) Connect the one end of the serial console cable to the serial port of the LS110. Figure 2-5 Connecting a serial console cable to the LS110 2) Connect the other end of the cable to the serial port of user’s computer. 3) Slide Data/Console switch to Console side. Figure 2-6 Data/Console switch of the LS110 4) Run a terminal emulator program such as HyperTerminal.
6) If the user logged into the LS110 successfully, a menu selection screen will appear on the computer as shown in Figure 2-7.

telnet 192.168.1.254 Or run a telnet program with parameters as follows. Figure 2-8 Telnet program set up example 2) The user has to log into the LS110. Type the user name and password. A factory default setting of the user name and password are both ‘root’. 3) If the user logged into the LS110 successfully, the same menu screen, as the one depicted in the serial console will be displayed. At menu selection screen, user can select each menu, by choosing the appropriate number.
3: IP Address Configuration A valid IP address needs to be assigned before the LS110 starts to work in the user's network environment. A network system administrator may provide the user with this IP address setting information for the network. The IP address must be unique within the network. Otherwise, the LS110 will not have a valid connection . Users can choose the desired IP mode , i.e., Static IP and DHCP. The factory default IP mode is Static IP mode.

IP mode : Static IP 2. IP address : 192.168.23.12 3. Subnet mask : 255.255.0.0 4. Default gateway : 192.168.1.1 5. Primary DNS : 168.126.63.1 6. Secondary DNS : 168.126.63.
Back, Refresh ---> 2 Enter IP address ---> Figure 3-3 Setting IP address Enter IP address to be changed. Note: The IP address in the form of 192.168.1.x is private in a sense that they are not assigned by an ISP. Application of the LS110 may require sending data back and forth over a public network, such as the Internet. In this case, it is required to assign a valid public IP address. The public IP address is generally purchased or leased from a local ISP. 3.1.
3.1.5 Default Gateway A gateway is a network point that acts as an entrance to another network. Usually, the computers that control traffic within the network or at the local Internet service provider are gateway nodes. The LS110 needs to know the IP address of the default gateway computer in order to communicate with the hosts outside the local network environment. For correct information on the gateway IP address, please refer to your local network administrator.
client computer receives this information when the IP address is provided at its boot-up. To obtain an IP address, the LS110 sends a corresponding DHCP request as a broadcast over the network after each reset. The reply generated by the DHCP server contains the IP address as well as the subnet mask, gateway address, DNS servers and the lease time. The LS110 immediately places this information in its non-volatile memory.
remember. A DNS server is a host that can translate such text-based domain names into the numeric IP addresses for TCP/IP connection. In order to use this DNS feature of the LS110, users need to set the IP address of this DNS server to be able to access the host with the domain name. The LS110 provides the way to configure IP addresses of DNS servers, i.e. Primary DNS server, Secondary DNS server. A secondary DNS server is specified for use when the primary DNS server is unavailable 3.3.
4: Host Mode Configuration 4.1 Host mode 4.1.1 Overview Host mode represents the operating session mode of the LS110. Several host modes are available for the data communication between serial devices and remote hosts. Table 4-1 The LS110 session modes Mode Description Select this mode, when users want the LS110 to operate as a TCP server. The LS110 stands by until there is any TCP connection request.
For each host mode, required parameters for configuration are summarized in Table 4-2.
For easier understanding of TCP modes, a simplified State Transition Diagram is often used. And to help users understand the diagram, the TCP state of the LS110 is briefly described as follows. Listen It represents “a waiting for a connection request from any remote host”. It is a default start-up mode when it is set as TCP server mode. This state is valid only in TCP server mode operation. Closed It means “No connection state at all”.
4.1.2 TCP Server Mode Operations The LS110 in this mode acts as a TCP server, and the default TCP state is [Listen] in this mode. The LS110 supports only one TCP socket connection per one serial port. If a connection is currently established, any additional connection requests will be rejected. The remote host will be either Ethernet-Serial communication devices acting as a TCP client or a socket program acting as a TCP client running on users’ PC.
Figure 4-1 shows the State Transition Diagram of the session operations in TCP server mode. Incoming TCP connection request Listen Sync-Recvd Accept Reject Closed Established Incoming TCP disconnection request Inactivity time-out Incoming data from remote host Incoming data via serial port Data Figure 4-1 State Transition Diagram of TCP server mode 3) Parameters Local port This is the TCP port number through which remote host can connect a TCP session, and, send and receive data.

which means the connection request is being sent. If the remote host accepts the request, the state will be changed into [Established], which means a session has been opened. For a while, data will be transferred between the hosts. This is [Data] state. The session will be disconnected due to the request of one of them, which is its original state, [Closed].

detailed operation principles are the same as that of TCP server and TCP client mode. See section 4.1.2 TCP Server Mode Operations and 4.1.3 TCP Client Mode Operations for more details on each session mode.
4.1.5 UDP Tunneling Mode Operations The UDP tunneling mode operation is similar to that of TCP server/client mode except that it is based on UDP protocol and only one pre-defined remote host is able to communicate with the LS110. Users do not have to configure the parameter of inactivity timeout, since UDP is a connectionless protocol.
port, and send back the data from the serial port to the latest remote host who sent the UDP datagram. Virtual connection timeout will be reset to inactivity timeout value whenever there is any data transfer between remote host and the serial device. If other remote hosts send UDP datagrams while a virtual connection is established, the UDP datagram will be discarded.

4.2 Serial Port Configuration To attach the serial device to the LS110 serial port, its serial settings should match exactly to that of the serial device. 4.2.1 Baud Rate Baud rate settings for the LS110 is as follows. 1200, 2400, 4800, 9600, 19200, 38400, 57600 and 115200 The baud rate can be changed by ‘Baud rate’ menu of ‘Serial port configuration’.
4.2.2 Data Bits, Stop Bit(s), Parity The factory default setting of data bits, stop bits and parity are 8, 1 and None. They can be changed using each menu such as ‘Data bits’, ’Stop bit(s)’, and ’Parity’. ------------------------------------------------------------------------------Serial port configuration ------------------------------------------------------------------------------1.

4.3 Options 4.3.1 DTR/DSR Behavior The purpose of the DTR/DSR pins is to emulate modem signal control or to control TCP connection state. The DTR is a write-only output signal, whereas the DSR is a read-only input signal, on the LS110. The DTR output behavior can be set to one of three types: Always HIGH, Always LOW or Show TCP connection. If the DTR behavior is set to Show TCP connection, the state of the DTR pin will be maintained high if the TCP connection is established.
