SerialGate User Guide 33Ch. 4 Installation This chapter explains how to install SerialGate. It deals with LAN and serial connection guides for SerialGate to operate together with the target serial device. Connection Guide In order to connect SerialGate to network, you need to use RJ45 Ethernet port. It supports both 10Mbps and 100Mbps Ethernet connection (auto-sensing). Since SerialGate’s WAN/LAN port supports MDIX, it automatically detects any kind of cable. (Cross or direct LAN cable) Plug one end of a LAN cable to SerialGate and the other end to a hub, switch, or any other network device. First-Time Bootup First of all, please make sure that the power input you supply to the module is corresponding with the SerialGate model that you have. If an appropriate power input has been successfully supplied, SerialGate will power on and start booting. Although there is no power LED to check the status, you can check by LEDs on the RJ45 Ethernet port. LED status operation is described in Chapter 3. Hardware Description. An IP address is required to access SerialGate’s web interface or telnet command-line configuration tool. By factory default, a static IP address is assigned to SerialGate. After the initial connection, you can either manually assign a different IP address or set SerialGate to automatically get an IP address from a DHCP server. While this depends on your network environment and policy, it is strongly recommended that a user assigns SerialGate with a unique static IP. Connecting to SerialGate In order to view current SerialGate’s settings or modify them, you need to make a Web or Telnet connection to SerialGate. IP address is required information to make a connection. There are two ways you can know the current IP address of Eddy.

SerialGate User Guide 44 Serial settings for SerialGate are as follows. Menu Default Descriptions Operation Mode COM Select the operation protocol that will be applied in the serial port. Disable Disable the serial port. COM Redirector Use the serial port of SerialGate as a virtual COM port in Windows 2000/XP/2003/Vista. TCP Server SerialGate 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. After socket connection, data between socket and serial port will be transmitted. TCP Client SerialGate acts as a socket client in this mode. It tries to connect to the server IP address and the socket number assigned when a certain server waits for connection on the network. All data between the socket and the serial port is transferred untouched after the socket connection is established. TCP Broadcast SerialGate works as a server, accepting up to 5 simultaneous connections from socket clients. Data transmitted from SerialGate is broadcast to each socket client. TCP Multiplex SerialGate works as a server, accepting up to 5 simultaneous connections from socket clients. The difference between TCP Broadcast and TCP Multiplex is that Multiplex allows each socket to communicate exclusively. That is, serial data in response are only transferred to the sender socket. UDP Server SerialGate works as a UDP server, waiting for UDP connection from the client on the network. Socket number for awaiting connections can be set in ‘Local socket
SerialGate User Guide 45Menu Default Descriptions port’ field. Once a UDP packet is received to the socket that waits for the connection, the data is transmitted to the serial port. The data input from the serial port is put into UDP packets, which eventually are sent to the client. UDP Client When the data is input to the serial port, UDP packets are sent using the preset IP address and the socket number of the server. Pair_Master/ Pair_Slave It extends a serial cable between DTE and DCE to network, and enables communication not limited to distance. Two devices are required for this feature and set one to Pair_master and another to Pair_Slave. It can be used for serial communication tunneling. MODBUS ASCII Connect MODBUS/ASCII SLAVE using serial port and make user of MODBUS/TCP MASTER feature using LAN port in PC. This feature enables MODBUS media converter function.

If the mode is set to Data Only, only TxD, RxD, and GND signal lines are used in inter-device communication. If the mode is set to Modem Signals, all modem signals except RI(Ring Indicator) are asserted, tested, and used in communication. (Options: Data Only, Modem Signals) Remote IP Address / Port 0.0.0.0 / 4000 If the Operation Mode is in TCP Client or UDP Client or Pair_Master mode, set the IP address and the socket number to connect to.
SerialGate User Guide 47Menu Default Descriptions Keepalive Check Time 0 After a certain amount of time passes without any communication after the socket connection between the given serial port and the server is established, automatically disconnect the socket connection. Valid from 0 to 32767 sec. For example, if the operation mode is set to TCP Server and Alive Check Time is configured to 10, TCP Server will listen for the client’s connection and eventually establish a connection. Since the check time is 10 seconds, the server will wait for 10 seconds until the client connected to it sends any packet. If there is no data for 10 seconds, server will quit the connection and return to the listening state. This option is helpful in preventing communication obstacles that occur when either SerialGate or the client quits unexpectedly (i.e. Sudden black out, reboot, LAN cable cut, etc.). In these cases, the other part of communication might not recognize the failure of its partner. Such misunderstanding can cause communication errors. If the value is set to 0, this function is disabled. Once connected socket will be retained until explicitly disconnected. (Only applies to TCP Client, TCP Server, TCP Broadcast, and TCP Multiplex operation modes.) Latency Time 0 This needs to be set when consecutive data from the given serial port needs to be transmitted to socket at once. For example, if 100 bytes of character string are to be transmitted from the serial device to a server through SerialGate, bypass is set to 0 for the latency time. Although it provides immediate sending through SerialGate, the server could be received a lot parts of divided packets. If the latency time is not 0, SerialGate will wait for the time and check new data. If there is new data, SerialGate repeatedly wait for the time. Otherwise, SerialGate will transfer the buffered data, but it could not run in real time.
SerialGate User Guide 48Menu Default Descriptions Port Login Disable When the Operation Mode is set to TCP Server, ask for the username and password when the client tries to connect (Options: Enable, Disable) Passive Username serialgate When the Operation Mode is set to TCP Server, set the username to ask for. 16 Characters at maximum.

SerialGate User Guide 77Ch. 8 Application SerialGate can be used in many practical applications in various fields. Here we present some of them. Com Port Redirector With COM Port Redirection, a user can use serial port connected to SerialGate on the network as if it is a serial port on PC. Install Com Port Redirector and set the following steps. (For installation, please refer to Com Port Redirector manual enclosed in CD. In the picture below, IP address of SerialGate is 192.168.0.247, and the first serial port is being used. A user can open Com 21 and use serial device connected to SerialGate.
SerialGate User Guide 78In order to correspond to the Redirector setting of PC, change the setting in the first serial port of SerialGate as follows. TCP_Server (TCP/IP connection from PC to SerialGate) In PC’s socket program, connect the first serial port of SerialGate. Since socket number for the first port of SerialGate is default 4001, try to connect to SerialGate’s IP address and socket number 4001 when connecting from a PC to SerialGate. As shown below, change the Operation Mode to TCP_Server and confirm the socket number waiting for connection. . Check the communication speed of a serial device to be connected to serial port, and set it to Com Specification.
SerialGate User Guide 79 TCP_Client (TCP/IP Connection: SerialGate  PC) Since it is a connection from SerialGate to a PC, change the Operation Mode to TCP_Client and register PC’s IP address and socket number to be connected. Check the communication speed of a serial device to be connected to serial port, and set it to Com Specification.
SerialGate User Guide 80 Pair (Serial Line To Serial Line) This structure is mainly used when the cable length between PC and serial device is short so a user needs to extend the communication distance. This approach consists of two SerialGates connected in Pair. Setting for SerialGate 1 In order to perform Master features, change Operation Mode to Pari_Master. Check the communication speed of a PC and set it in Com Specification, and also register Slave SerialGate’s IP address and port number in Remort IP/Port.
SerialGate User Guide 81 Setting for SerialGate 2 In order to wait for Master connection, set Operation Mode to Pari_Slave and register the socket number to be connected in Local Socket Port.
SerialGate User Guide 82 Ch. 9 Appendix Troubleshooting This section describes procedures for troubleshooting problems you may encounter with SerialGate. Troubleshooting Installation Problems If you cannot access the connected serial device via SerialGate, first check the network connection and cabling.  Check the physical cabling to ensure all cables are plugged in (Ethernet and DB-9 serial cable)  If the appropriate LEDs are not illuminated, then there is probably a bad 10baseT or 100baseTX cable, or the hub port is bad. If possible, try a different cable and hub port, or try connecting a different device to the cable.  Verify that you are using the correct values for both IP Address and Port Number.  If you are using a hub, verify that the hub port is operating correctly by trying SerialGate on a different port. Troubleshooting Network Configuration Problems  If you are using TCP/IP, make sure that your computer and SerialGate are on the same IP segment or can reach each other with a PING command from the host. The IP address you assign to SerialGate must be on the same logical network as your host computers (e.g., if your computer has an IP address of 192.189.207.3 and the subnet mask of 255.255.255.0, SerialGate should have an IP address of 192.189.207.x, where x is an integer between 1 and 254), or you must properly configure your router address to work with SerialGate.  If your Device Server is set to Auto or DHCP for obtaining an IP Address, it is possible that SerialGate’s IP address can change. Either configure your DHCP server to give SerialGate a permanent lease, or configure SerialGate to be on a STATIC IP address outside the scope of the DHCP addresses.
SerialGate User Guide 83 The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP address is correctly loaded into SerialGate (via the displayed or printed configuration information or through the remote console), and make sure that no other nodes on the network have this address (duplicate addresses are the biggest cause of TCP/IP connectivity problems). If the IP address is not correct, then check whether the loading procedure was properly executed.  Also verify that the host computer and SerialGate are using the same subnet masks(for example, if SerialGate has a subnet mask of 255.255.255.0, the host must have the same subnet mask) or that the router is properly configured to pass data between the two devices.  If the wrong IP address is loaded, check your network for DHCP server, and make sure that the server is not set up to load wrong IP addresses into SerialGate. Troubleshooting Windows Problems  If you are having trouble accessing the connected serial device through Windows, ensure you can ping SerialGate using the command PING x.x.x.x, where x.x.x.x is the IP address of SerialGate. If you cannot ping SerialGate, you will not be able to access the serial device.  If you are running COM port redirector and the software reports an error, verify that the correct virtual COM port is being used when the application runs. Verify that your application’s COM port settings have been changed to use the virtual COM ports. Firmware Update using FTP A user can upload firmware using web browser, FTP, and etc. 1) Connect to SerialGate with FTP, using correct username and password. (Default: serialgate, 99999999) 2) Issue a command ‘bi’ for binary file transfer mode. Optionally use ‘hash’ to see the data transfer mark. 3) Issue ‘put’ command to upload the firmware file. 4) After getting a ‘Transfer complete’ message, issue a command ‘bye’ to disconnect. Now we are ready to update the firmware.
SerialGate User Guide 84 5) Connect to SerialGate via Telnet, using correct username and password. (Default: eddy, 99999999) 6) After the login, you are already at the default directory where the firmware resides. Update can start right away. 7) Issue a command ‘ls’ to make sure firmware files are both successfully uploaded. 8) Use ‘upgrade’ command to write this file into SerialGate’s Flash memory. Upgrade application automatically detects whether the given firmware is kernel or file system. 9) Usage: Upgrade <firmware name> (Filename is case-sensitive.) 10) Make sure ‘Flash Write OK’ and ‘Flash Verify OK’ messages are displayed. 11) Enter ‘reboot’ to restart SerialGate. Now SerialGate will run with the new firmware.
