  Installing the Serial Device Server  Silex  Page 5 Part Number 140-00188-180  Chapter 2 Installing the Serial Device Server Hardware   The Serial Device Server includes most of the hardware and software components required for installation.  The one item that you will need to purchase separately is a cable to connect your serial device to the Serial Device Server (this cable is not included because of the wide variety of connector types used on serial devices).  Verify Package Contents  The Serial Device Server includes the components listed in Table 1. Please ensure that all materials listed are present and free from visible damage or defects before proceeding.  If anything appears to be missing or damaged, please contact Silex.   Table 1  Package Contents Description SX-500 or SX-510 Base Unit (SX-500 wireless models include an external pole antenna) Setup Guide CD-ROM containing ExtendView software, Serial Port Emulator Software, and User’s Reference Guide AC Power Supply with power cord Warranty Card  Installing the Serial Device Server Follow the steps below to install the Serial Device Server.  The Serial Device Server’s factory default settings should be sufficient for most serial connections; however, some of the configuration settings may have to be changed for your particular installation.    1.  Before attempting to install the Serial Device Server, make sure you have installed and set up your serial device as described in the documentation that came with the device.
 Page 6  Silex  Installing the Serial Device Server Part Number 140-00188-180 2.  Write down the 12-digit MAC (Media Access Code) address printed on the label located on the bottom of the Serial Device Server (for example: 004017023F96).  You may need this number in order to configure the Serial Device Server. 3.  If you have a wireless model, connect the antenna to the unit. 4.  Connect the Serial Device Server to your serial device.  If you are using RS-232, you may use standard PC cabling (you should normally use a null modem crossover cable).  The 9-pin connector pinouts and cabling are as follows:  RS-232 connector pinouts and cabling If you are using RS-422 or RS-485 in full-duplex or half-duplex modes, you will need a special cable.  In addition, if the Silex Serial device Server is the last one in a chain, then a 120-ohm resistor should be placed between pins 2 and 6 (for full-duplex mode) or pins 4 and 5 (for half-duplex mode). IMPORTANT:  IF YOU ARE USING RS-422, RS-485, OR RS-485 HALF-DUPLEX, YOU MUST SET THE SERIAL PORT LINE MODE AS DESCRIBED IN CHAPTER 3 OF THIS MANUAL. The RS-422 and RS-485 pinouts and cabling are shown in the following diagrams:  RS-422/485 full-duplex connector pinouts and cabling  RS-485 half-duplex connector pinouts and cabling 5.  Plug the Serial Device Server power supply adapter into a suitable AC receptacle, and then plug the power supply cable into the Serial Device Server.  Alternatively, you can use pin 9 on the 9-pin connector to provide power to the Serial Device Server (1 amp @ +5V is required). The Serial Device Server will run through a sequence of power-up diagnostics for a few seconds.
 Installing the Serial Device Server  Silex  Page 7 Part Number 140-00188-180 •  If the Serial Device Server is operating properly, the LEDs will blink momentarily and then go out, the yellow and green LEDs will illuminate if the wireless network is active, and the orange LED will illuminate, indicating the device is receiving power. •  The unit powers up in the Normal mode, which provides for connection from the network to device(s) connected to the serial port of the Serial Device Server. •  If the orange LED blinks continuously in a regular pattern, a problem exists.  If this is the case, try powering the unit OFF and then ON again.    .  6.  Connect the Serial Device Server to your network through a switch or hub using a category 5 (CAT5) Ethernet cable. Serial Device Server wireless models automatically detect the presence of this cable, and will switch off the wireless networking functionality as long as the cable is plugged in.  7.  The Serial Device Server’s IP address must be configured before a network connection is available.  If your network offers DHCP (Dynamic Host Configuration Protocol), the Serial Device Server will automatically search for a DCHP server upon power up and obtain an IP address.  If your network does not offer DHCP, a static (fixed) IP address must be assigned (see your system administrator for assistance).  If you use DHCP, make sure that the length of the DHCP lease is adequate so that the IP address of the Serial Device Server does not change. Monitoring Serial Device Server Status   You can monitor the Serial Device Server status using the yellow, green and orange LED status indicators on the monitor. Table 2 defines the default functions of the LED status indicators.  Table 2 Status Monitors  Function State  Status On  The Serial Device Server is receiving power Off  The Serial Device Server is not receiving power Power Orange  Blinking  The Serial Device Server power supply is malfunctioningYellow Off Green Off  No network activity Yellow On Green Off  10base-T network active Yellow Blinking Green Off  10base-T network data received Network Status Yellow or Green Yellow Off Green On  100base-TX network active NOTE:  Pin 9 is normally configured for supplying +5V from an external power source in lieu of using the AC power supply adapter.  If you wish to use this pin as the Ring Indicator (RI) modem signal on the SX-500 (not available on the SX-510), open the  enclosure and move the jumper on connector JP1 onto pins 2 and 3 of this connector. NOTE:  SILEX RECOMMENDS USING A HARDWIRED ETHERNET CONNECTION FOR CONFIGURING WIRELESS SERIAL DEVICE SERVERS. If you have a wireless Serial Device Server model and cannot use an Ethernet connection, refer to step 4 in the First Time IP Address Configuration section of this chapter for instructions on how to set up the Serial Device Server using a completely wireless Ad Hoc environment.

 Configuring the Serial Device Server  Silex  Page 9 Part Number 140-00188-180 Chapter 3 Configuring the Serial Device Server   This chapter describes the methods for configuring the basic settings of the Serial Device Server, including the IP address, serial port settings, and wireless security.  The Serial Device Server also has an extensive range of advanced configuration capabilities that are described in Chapter 5, Appendix A, and Appendix B.  The Serial Device Server configuration should be done by a network administrator or another person with technical knowledge of TCP/IP networking and serial communications. Basic Configuration Requirements In order to use the Serial Device Server, the following basic parameters must be configured:  TCP/IP Settings: • IP Address • Subnet Mask • Router Address  Note:  The TCP/IP settings can be automatically configured using DHCP.  Wireless Configuration Settings: • SSID •  Mode (Infrastructure or Ad Hoc) •  Channel (required only if using Ad Hoc mode)  Security Settings: •  Wireless Encryption Mode (WPA2, WPA, WPA2-WPA, WEP) •  Wireless Encryption Settings •  Wireless Authentication Mode (WPA-PSK, Open System, Shared Key, TTLS, TLS, LEAP, PEAP, EAP-FAST) •  Wired Authentication Mode (TTLS, TLS, PEAP, EAP-FAST) • Authentication Settings  Note:  There are numerous possible encryption and authentication settings, and every network can have different settings. Please refer to Appendix A for a detailed summary of these settings.  Serial Port Settings (must match the settings of the attached serial device): • Baud Rate (Speed) • Parity
 Page 10  Silex  Configuring the Serial Device Server Part Number 140-00188-180 • Character Size • Flow Control •  Line Mode (RS-232, RS-422, RS-485 full-duplex, RS-485 half-duplex; RS-422 and RS-485 are supported on the SX-510 only)  In addition to the above parameters, the Serial Device Server allows you to configure numerous other capabilities.  These other capabilities provide you with the unparalleled flexibility to use the Serial Device Server on virtually any 802.11 or Ethernet network with a wide range of serial devices.   Configuration Methods There are three ways to configure the Serial Device Server:  • ExtendView.  ExtendView is a simple Graphical User Interface configuration program for Windows.  In addition to setting up the initial Serial Device Server configuration, ExtendView also has the advantage of allowing you to perform bulk configuration of multiple Serial Device Servers simultaneously.  • Internal Web Pages (HTTP).  You can use any standard web browser to access the Serial Device Server internal web pages.  These web pages provide an easy-to-use graphical interface for configuring the Serial Device Server.  In order to use the internal web pages for the first time, you must assign the Serial Device Server IP address using some other method (for example, DHCP or arp/ping). This initial IP address assignment need only be done one time.  • Internal Command Console.  The internal command console provides a sophisticated command line interface for advanced users to configure the Serial Device Server.  It can be accessed by connecting a serial cable to the serial port and using console mode switching as descried in chapter 4.  Once the IP address has been assigned, the internal command console can also be accessed via TELNET, or via ExtendView and the internal web pages.    If you have a Serial Device Server wireless model, Silex recommends that you temporarily plug the Serial Device into a wired Ethernet network during the configuration process. Although it is possible to configure the Serial Device Server with a completely wireless setup, it is much simpler to perform the process using a wired Ethernet connection.  This is primarily because the wireless security on most wireless networks prevents the addition of a new wireless device unless all security parameters are first entered into that device.  As a result, you must set up a temporary dedicated ad hoc wireless network in order to configure the Serial Device Server in a completely wireless environment (refer to the step 4 in the First Time IP Address Configuration section of this chapter for instructions on how to set up the Serial Device Server using a completely wireless Ad Hoc environment).  Configuring the Serial Device Server using each of the above methods is described in the following sections of this chapter.
 Configuring the Serial Device Server  Silex  Page 11 Part Number 140-00188-180 Using the ExtendView Utility to Configure the Serial Device Server (Ethernet Connection)      The ExtendView Utility is the easiest way to initially configure the Serial Device Server from a Windows PC because it allows you to directly set the IP address into an unconfigured Serial Device Server, and it allows you to view the IP addresses of all of the Serial Device Servers on your network.  It has limited capabilities for configuring 802.1X authentication, but it can be used in conjunction with either the internal web pages or the internal command console for complete configuration capabilities.  ExtendView is a component of the CD-ROM that is included with the Serial Device Server, or it can be downloaded from the Silex website.  To install ExtendView, simply follow the on-screen installation instructions.  The Serial Device Server configuration procedure is as follows (please note that the screens may be slightly different than shown, depending on the Serial Device Server model and the firmware and software revision levels).     1.  Start the ExtendView Utility by clicking on Start, Programs, silex technology, ExtendView, and then ExtendView.     2.  When the Welcome screen appears, click on Next, choose any name for your View Name, select Automatically create a view with default settings (or configure the view to your preferences), and then click Finish.    NOTE:  Skip this section if you do not have a Windows PC or if you do not have an Ethernet connection available for configuring your Serial Device Server wireless model.
 Page 12  Silex  Configuring the Serial Device Server Part Number 140-00188-180  3.  Right-click on the Serial Device Server that you want to configure from the displayed list, and then left-click on Configuration.  The default Serial Device Server name is SLXxxxxxx (where xxxxxx is the last six digits of the MAC address from the label that is affixed to the Serial Device Server).     4.  If you do not have a DHCP server, you will be asked to manually enter an IP address (if you are not sure what IP address to enter, ask your network administrator). Click OK when you are finished.    5.  The Server Configuration window will appear.  Check the IP address setting to make sure it is correct.  If necessary, change the Subnet Mask and Gateway. If you have a WINS server, enter its address or click Use DHCP to Locate WINS Server.  If desired, you can configure advanced TCP/IP settings by clicking the Advanced TCP/IP button (refer to Chapter 5 for information).  This advanced configuration can be done at a later time, however.     NOTE: If you are using DHCP on your network, the SX-500 should have acquired valid IP settings at this point and no further configuration is necessary.  However, for some installations, a static IP address is preferred.  If your DHCP server does not allow the SX-500 to keep its assigned IP address permanently, then you must manually assign an IP address.  In this case, use a static IP address outside the range reserved for DHCP (see your DHCP server documentation for details).  To assign a static IP address, select Set Permanent as the IP Address Resolution, and assign a valid static IP address for your network.  Click on OK to save the new settings.
 Configuring the Serial Device Server  Silex  Page 13 Part Number 140-00188-180  6. Click the Wireless tab to configure the 802.11 wireless settings (for wireless models only; skip to the next section if you have a wired model).  To operate on an 802.11 network, the Serial Device Server configuration must be configured with the wireless configuration and security parameters necessary for the Serial Device Server to communicate over your wireless network (check with your network administrator if you do not know these parameters).  •  Select either Infrastructure (if you are using an access point) or Ad Hoc (point-to-point) as the wireless mode •  Enter the SSID for your network •  If you are using Ad Hoc, select the RF channel (not required for infrastructure) The other parameters on this tab do not normally need to be changed (refer to Chapter 5 for information on advanced configuration).   Now click the Configure Wireless Security button to configure the wireless security parameters.   7.  If you are using WPA2-PSK, select WPA2 as the Encryption Mode and select PSK as the Authentication Type.  If you are using WPA-PSK, select WPA as the encryption mode and select PSK as the Authentication Type.  For both WPA2-PSK and WPA-PSK you must enter the Pre-Shared Key for your network and select whether you want a Group Key.  Note that it is not necessary to enter a User ID or password.  If you are using WEP, select 128-bit or 64-bit as the Encryption Mode and Open Systems or Shared Key as the Authentication Type.  Enter the WEP keys in hexadecimal format, and select the transmit key (Key Selection).  ExtendView does not fully support configuration of the 802.1X EAP types, so Silex recommends using the internal web pages or internal command console for 802.1X configuration as described later in this chapter.  Click OK to return to the Server Configuration window, and then click the I/O port tab to configure the serial port.
 Page 14  Silex  Configuring the Serial Device Server Part Number 140-00188-180  8.  You do not need to change any of the settings in this window.  Click the Serial Settings button to configure the serial port.    9.  Configure the serial port settings so that they match the settings on your device.  For example, if your device is set for 9600bps, odd parity, and XON/XOFF flow control, you must change the settings on the Serial Device Server to these settings.  If are using either RS-422 or RS-485 (SX-510 only), select 422 or 485 as the Mode.  Select Half as the Duplex type if you are using RS-485 half-duplex.   Click OK when you are finished to return to the Server Configuration window and then click OK again.      10. Click OK to save your changes and reset the Serial Device Server.  If you are configuring a Serial Device Server wireless model, unplug the Ethernet cable. You can now use the Serial Device Server on your network.  You may skip the remaining sections of this chapter, although this information is useful for future reference.
 Configuring the Serial Device Server  Silex  Page 15 Part Number 140-00188-180 First-Time IP Address Configuration    If you are configuring the Serial Device Server from a non-Windows computer or if you cannot use an Ethernet connection, you must first configure the Serial Device Server IP address.  Note that it is only necessary to perform this task one time -- once the address has been configured, the Serial Device Server can be accessed from any computer on the network that has the appropriate privileges.  The steps are as follows:  1.  If your network has a DHCP server and you can use an Ethernet connection to the Serial Device Server: a.  Make sure your PC is connected and has access to your network. b.  Connect an Ethernet cable from your network hub to the Serial Device Server (if you have a wireless Serial Device Server and do not have hardwired capabilities, then you must go to Step 4 below for setup instructions). c.  Power on the Serial Device Server. d.  The administration program on most DHCP servers logs the IP address and MAC address of each DHCP client.  The MAC address of the Serial Device Server can be found on the label affixed to the unit.  If your DHCP server has logged this information, write down the IP address of the Serial Device Server for future reference.  You are now ready to configure the Serial Device Server (skip the remainder of this section). e.  If your DHCP server does not provide client information or if you do not have access to the DHCP server, then you can get the IP address by connecting a serial device such as a printer, a Windows PC running HyperTerminal, or another serial device capable of printing ASCII characters to the serial port the Serial Device Server). Your serial device must be set at 115.2Kbps, 8-bit character size, and no parity.   f.  With the serial device and Serial Device Server switched on and ready, press the Reset pushbutton on the Serial Device Server. This will cause the Serial Device Server configuration data to be sent to the connected serial device.  The serial device should display or print the current IP address assigned to the Serial Device Server by your network DHCP service. Write down this address for future reference. You are now ready to configure the Serial Device Server (skip the remainder of this section). 2.  If you can connect the Serial Device Server via Ethernet but do not have a DHCP server, then you must use the following procedure for the first-time IP configuration of the Serial Device Server. a.  Make sure your PC is connected and has access to your network b.  Connect an Ethernet cable from your network hub to the Serial Device Server.  The Serial Device Server must be on the same network segment as the PC (that is, there can be no router between the Serial Device Server and the PC). c.  From the Windows Command Prompt (MS-DOS Prompt), the Mac OS X Terminal Utility, or the UNIX/Linux command line, enter the command   arp –s ipaddress macaddress ping ipaddress  Where  ipaddress is the desired IP address of the Serial Device Server and macaddress is the MAC address of the Serial Device Server (found on the label NOTE:  Skip this section if you have already configured the SX-500 IP address with ExtendView
 Page 16  Silex  Configuring the Serial Device Server Part Number 140-00188-180 affixed to the Serial Device Server). For example: arp –s 192.168.5.53 00:40:17:00:00:01 ping 192.168.5.53 Note that Windows systems use the format xx-xx-xx-xx-xx-xx for the MAC address (for example, 00-0017-00-00-01).   You will see a reply from the Serial Device Server with the number of bytes and other information if the address was successfully set.  If you get an error message or no response, then the IP address was not set.  If this is the case, the Serial Device Server may not be at its default configuration.  To reset the Serial Device Server to its default settings, hold down the reset pushbutton for more than five seconds. d.  You are now ready to configure the Serial Device Server (skip the remainder of this section).   3.  If you are using a wireless connection for the first-time configuration of the Serial Device Server, you must set up a temporary ad hoc wireless connection as described in the following steps.  Please note that because this is a fairly complex process, we do not recommend it unless it is not possible to use a wired connection. a.  Disconnect your PC and the Serial Device Server from your network, and temporarily set the PC settings as follows: •  IP address: 192.0.0.191 • Wireless Mode: Ad Hoc (sometimes referred to as Peer-to-Peer) • Channel: 11 •  SSID (or wireless network name): serserv  b.  Power on the PC and the Serial Device Server. You can connect to the Serial Device Server by specifying its default IP address of 192.0.0.192 using a web browser as described in the next section. When you have connected to the Serial Device Server, you must then change the IP address and enter the required wireless networking parameters using either the web browser interface or the internal command console (see next two sections) for operation on your wireless network. c.  After you complete the entire Serial Device Server configuration process, you must set your PC back to its original network settings. NOTE:  Skip the following step if you have configured IP address of the Serial Device Server using an Ethernet cable.
 Configuring the Serial Device Server  Silex  Page 17 Part Number 140-00188-180 Using a Web Browser to Configure the Serial Device Server After you have entered an IP address into the Serial Device Server, you can use any standard web browser to access the internal web pages for configuring the Serial Device Server.  Simply specify the IP address of the Serial Device Server in your browser and then follow the steps below:         1.  When you have connected to the Serial Device Server, you will get the Server Info page.  Click Login on the left side of the screen.    2.  Enter the password access and press Submit.     3.  You will return to the Server Info page, but new options will be listed on the left side of the screen.  Click on TCP/IP.   IMPORTANT:  You must click the Submit button when you have finished configuring an internal web page.  If you do not do this, your changes will not be saved. You may skip this section if you have completely configured the SX-500 using ExtendView.  However, if you have advanced configuration requirements, such as 802.1X EAP configuration, then you may need to use the internal web pages as described in this section because ExtendView does not support these capabilities.
 Page 18  Silex  Configuring the Serial Device Server Part Number 140-00188-180 If you used DHCP, verify that the IP address is correctly set.  If you used the default 192.0.0.192 IP address, you MUST change it to a new valid IP address.  If necessary, change the Subnet Mask and Gateway.  It is generally not necessary to change the other parameters on this page (refer to Chapter 5 for advanced configuration information.  Note that on-line help information is available on every configuration page.  Click the Submit button at the bottom of the window (you may need to scroll) to save your changes.    4. Click Wireless on the left side of the screen to configure the 802.11a/b/g wireless settings (for WLAN models only; skip to the next section if you have an Ethernet model).  To operate on an 802.11a/b/g network, the Serial Device Server configuration must be configured with the wireless configuration and security parameters required to allow the Serial Device Server to communicate over your wireless network (check with your network administrator if you do not know these parameters).  •  Select either Infrastructure (if you are using an access point) or Ad Hoc (point-to-point) as the wireless mode •  Enter the SSID for your network •  If you are using Ad Hoc, select the RF channel (not required for infrastructure) The other parameters on this page do not normally need to be changed (refer to Chapter 5 for information on advanced configuration).   Click the Submit button at the bottom of the window (you may need to scroll) to save your changes.   Now click Configure Network Security to configure the wireless security parameters.   NOTE: If you are using DHCP on your network, the SX-500 should have acquired valid IP settings at this point and no further configuration is necessary.  However, for some installations, a static IP address is preferred.  If your DHCP server does not allow the SX-500 to keep its assigned IP address permanently, then you must manually assign an IP address.  In this case, use a static IP address outside the range reserved for DHCP (see your DHCP server documentation for details).  To assign a static IP address, select Set Permanent as the IP Address Resolution, and assign a valid static IP address for your network.  Click on OK to save the new settings.

 Using the Serial Device Server  Silex  Page 23 Part Number 140-00188-180   Chapter 4 Using the Serial Device Server with Your Application The Serial Device Server includes a number of capabilities that enable it to be used in a wide range of applications.  These capabilities include:  1.  Serial Port Emulator (SPE) software 2.  Raw TCP connection 3. RFC2217  4. ECable Mode 5. Print Server mode 6. FTP 7.  Console mode switching 8. AT commands 9.  SNMP traps and Email alerts  These methods are described in the following sections. Serial Port Emulator The Serial Port Emulator (SPE) software emulates a standard Windows COM port.  That is, it creates a virtual COM port that functions exactly like the Windows COM1 and COM2 serial ports, except that the I/O actually goes out over the Ethernet or WLAN to the Serial Device Server and to the serial device that is connected to the Serial Device Server.  As a result, any application program that uses a standard Windows COM port can also use the Serial Port Emulator.  The SPE is therefore especially useful if you have existing programs that use Windows COM ports.  The SPE software is a component on the CD-ROM that is included with the Serial Device Server, or it can be downloaded from the Silex website.  To install it, double click on the installer icon and follow the installation instructions. When the installation is complete, you can run the SPE software by clicking Start -> Programs -> Silex technology -> Serial Port Emulator -> Serial Port Emulator.
 Page 24  Silex  Using the Serial Device Server Part Number 140-00188-180   After the Serial Port Emulator software has started, you will see a list of all the configured Serial Device Servers on the network.  Right click on the name of the Serial Device Server that you want the virtual COM port to connect to (the default name is SLXxxxxxx, where xxxxxx is the last six digits of the Serial Device Server MAC address), and then click Virtual Port.  You will be asked to select the name of the virtual COM port (for example, COM3).       Click OK after you have selected the name, and you now ready to use the virtual COM port.    Using virtual COM port is identical to using a normal COM port.  For example, if you configure a virtual COM port called COM3, this port will show up as one of the available serial ports when you use the Windows HyperTerminal Accessory program.   Raw TCP connection You can communicate directly from your application program to the Serial Device Server using a raw TCP connection.  This is done by opening a TCP port on the Serial Device Server and then sending and receiving data to this port via a socket or equivalent API. This method is more efficient than using the Serial Port Emulator, and does not require any additional software to be installed on your computer.  If you are using a raw TCP connection, the default TCP port number (you can use any or all of these port numbers) for normal connections. If you want to be able to access your device’s modem control signals from your computer system, then the TCP port number is 9200 (this enables RFC 2217 support).  You can change the port number, if desired, by modifying one of the Serial Device Server services.  To change the TCP port number:    1.  Connect to the Serial Device Server with a web browser (see chapter 3 for instructions on doing this);  2.  After you have logged in, click I/O Services on the left side of the page.   3.  Click on the service name that you want to change (any one of the services is OK, provided that you are not using the existing TCP port number of that service for a different application). 4. Change the Raw TCP Port to the desired number (must be greater than 1023). 5. Click Submit to save your change.  You can test this connection by using the TELNET utility from the Windows Command Prompt (MS-DOS prompt), Mac OS X Terminal Utility, or UNIX/Linux command line as follows:   telnet ipaddress portnumber
 Using the Serial Device Server  Silex  Page 25 Part Number 140-00188-180  where ipaddress is the IP address of the Serial Device Server and portnumber is the Serial Device Server TCP port number.  For example:    telnet 192.168.5.53 9100  In this example, if you have a serial printer or other device capable of displaying ASCII characters connected to the Serial Device Server serial port, then every character you type should be printed on that serial device (buffered serial devices may need you to type a control character such as a formfeed (CONTROL-L) before the characters are printed).  RFC 2217 Remote Modem Control Support RFC 2217 allows you to access your device’s modem control signals over the network.  It is especially useful for migrating applications that use modem controls from a direct serial connection to a serial device server network connection.  You can utilize RFC 2217 from the Silex Serial Port Emulator software (see below), or by connecting to TCP port 9200 from your application program.   ECable Mode Normally, it is up the computer to initiate a connection to the Serial Device Server.  For some applications, it is desirable for the Serial Device Server to initiate the connection to the computer.  The Serial Device Server supports this capability through its ECable feature.    To set ECable mode, use a web browser to access the Serial Device Server internal web pages (see chapter 3 for instructions on using the internal web pages).  After you have logged in, click I/O port on the left side of the screen.      You can now enable ECable mode and set the required parameters.  1.  Enable ECable mode by clicking the radio button. 2.  Enter the address (Destination Address) of the computer or other device that will be communicating with the Serial Device Server) 3.  Enter the TCP port number (Destination Port) used by the destination device for communicating with the Serial Device Server (must be greater 1023).   4.  If desired, change the ECable Connection Attempt Time.  This specifies the time interval between connection attempts.  For example, by default the Serial Device Server will try once every 30 seconds to make a connection to the destination device; if it fails to make this connection, it will wait 30 seconds before attempting again.  Changing this interval will reduce or increase the amount of network traffic. 5.  It is also possible to use UDP instead of TCP for communicating to and from the Serial Device Server.  If you wish to use UDP, then:
 Page 26  Silex  Using the Serial Device Server Part Number 140-00188-180 a.  Select UDP as ECable I/O Mode. b.  Enter the UDP port number (Destination Port) used by the destination device to communicate with the Serial Device Server.  This number must be a valid port on the destination device (check the documentation for that device to determine the valid port numbers). c.  Enter the UDP port number (Local Port) used by the Serial Device Server to communicate with the destination device.  This number must be greater than 1023, but is otherwise arbitrary.    Print Server Mode You can use the Serial Device Server as a standard TCP/IP print server, which is very useful if you are connecting the Serial Device Server to a serial printer.  The Serial Device Server supports the following standards:  • lpr/lpd.  This is one of the most popular ways to print on a TCP/IP network.  Check your computer’s documentation to determine how to set up an lpr print queue.  Usually this simply involves specifying the IP address of the Serial Device Server as the printer’s address or host name.  Some implementations require a queue name; this name is the name of any of the Serial Device Server services.  To see the names of the Serial Device Server services, connect to the Serial Device Server with a web browser (see chapter 3 for instructions on doing this); after you have logged in, click I/O Services on the left side of the page.   • Port 9100.  This method is used to set up a Windows Standard TCP/IP port or for compatibility with software that supports the HP JetDirect Print Server (for example, HP Web JetAdmin).  To use this capability on Windows with the Add Printer Wizard, specify that you want to use a Local printer attached to this computer (not a network printer), and then select Create a new port, specifying Standard TCP/IP Port as the type of port.  It is also possible to change the TCP port number from the default 9100 for compatibility with other printer manufacturer’s software.  To do this, refer to the instructions in the Raw TCP Connection section of this chapter. FTP The Serial Device Server supports FTP binary or ASCII communications.  This can be used, for example, to send the contents of a file from a PC to a device connected to the Serial Device Server using the FTP protocol.  To use FTP, simply enter the standard FTP command from your PC with the IP address of the Serial Device Server (for example, ftp 192.168.5.50).  When the connection is made, enter any username and password.  You can then use the standard FTP put command to send the file from the PC to the device connected to the serial port on the Serial Device Server. Console Mode Switching The Serial Device Server allows you to dynamically switch the operation of the serial port from normal mode to console mode.  This allows your device to control the operation of the Serial Device Server by sending console commands (see chapter 6 and Appendix B for a description of the console commands).  Note that console mode can only be entered when there is no connection to a remote host.  NOTE: ECable mode cannot be used in conjunction with the Serial Port Emulator software.
 Using the Serial Device Server  Silex  Page 27 Part Number 140-00188-180 To switch the serial port to console mode, you must first define a console string.  When the Serial Device Server receives this string on the serial port, it will automatically switch the port to console mode.  To define the console string, use a web browser to access the Serial Device Server internal web pages.  After you log in, click I/O Port, and then select the desired port (S1 for the serial port).  When you get the I/O Port Settings page, enter any desired character string (for example, xyz) as the Console Mode String.  Click Submit to save your string, and then restart the Serial Device Server to make the change take effect.  Alternatively, you can define the console mode string using the console command from TELNET as shown in the following example:  SET PORT S1 CONSTR xyz  Once you are connected in console mode, you can send any of the console commands listed in Chapter 5.  Be sure to terminate each console command with a carriage return (ASCII 13) or linefeed (ASCII 10) character.  When you are finished using the console, you can return to the normal port operation by sending the command EXIT followed by a return or linefeed character.   AT Commands The Serial Device Server allows you to control the serial port using standard AT modem commands.  This allows you, for instance, to initiate connections and to switch between console mode and data mode by sending the appropriate commands.   These capabilities are similar to the console mode switching described in the previous section, but have the following advantages:  •  Your device can initiate a network connection •  Operation is compatible with software that uses the AT command set  The drawback, however, is that there is a slight delay when switching from data mode to AT command mode.  To use the AT commands, you must first enable this capability using the I/O Port Settings internal web page for the desired port (S1 for the serial port).  Change the Port Filter setting to AT in order to enable AT mode on that port and press the Submit button to save the change.  You must restart the Serial Device Server to make the change take effect.  You can also use the console to enable the AT capabilities.  For example, the command  SET PORT S1 FILTER AT  enables AT capabilities on the serial port.  Note:  If you use the AT commands on the serial ports, you cannot use SNMP traps or Email alerts for that port (you can use the SNMP traps and Email filters on a different port and on the GPIOs).   The AT commands are described in detail in Chapter 5. SNMP Traps and Email Alerts The Serial Device Server allows the user to define various alert conditions based on data received by the serial port.  For example, you could cause an alert to occur if a certain user-defined string of characters is received on the serial port.  When an alert occurs, it can be sent as an SNMP trap and/or as an Email message.    Details on using these capabilities can be found in Chapter 5.

Configuring SNMP The Serial Device Server Serial Device Server contains a Simple Network Management Protocol (SNMP) agent that collects and stores management information for network managers using standard SNMP commands. The management information is referenced as a hierarchically organized database called a Management Information Base (MIB).    To prevent naming conflicts, all of the manageable features of all products from all vendors are arranged in a single tree structure. Each vendor of SNMP equipment has an exclusive section of the MIB Tree.  Each branch of the MIB Tree has a number and name. The path from the top of the tree down to the point of interest forms the name of that point. A name created in this way is known as an Object ID or OID.
 Advanced Configuration  Silex  Page 33 Part Number 140-00188-180 Table 6 describes the messages used to communicate between the network manager and the SNMP agent, as defined in RFC 1157. Each SNMP message must contain a Community Name, which is used like a password.  The default Community name for the Serial Device Server Serial Device Server is PUBLIC.  Table 6  SNMP Commands Command Description GET  Retrieves management information for a specific managed object contained in the agent.   The GET message must contain the OID for the specified object.  The response is a GET-RESPONSE message containing either the current value of the requested object, or an indication as to why the request failed. GET NEXT  Retrieves management information from a non-specific managed object.   The GET NEXT contains either a complete OID or a fragment of an OID.  The response is a GET-RESPONSE message containing either the OID and data of the item immediately right of the specified OID in the tree or an indication as to why the request failed.   GET RESPONSE  This is the information sent back from the unit in response to the GET, GET NEXT command. SET  Requests a change to the value of a specified object.   The response is a GET-RESPONSE message with either an indication that the requested change had been made or with an indication as to why the request failed. TRAP  Sends a one-way notification from the agent to the manager that a significant event has occurred.  This is the only message initiated by the SNMP agent.   To configure the SNMP server settings:  7.  Log into the Serial Device Server internal web pages using a standard web browser.  Click Server Settings to access the screen shown in Figure 10.  You can then enter the relevant SNMP information for your network.

You must then restart the Serial Device Server to make the changes take effect. Configuring Serial Port Monitor Alert and Trap Configuration The Serial Device Server can be configured to scan and compare the data received on the serial port to user-defined strings.  A match with a string can be a source for SNMP traps and/or email alerts.    The match strings and corresponding email or web page message strings are configured from the Internal Configuration Console interface (accessible via TELNET).

Local> show port s1 trigxmt  Index #  Xmit String ------   ---------------   0:     The trigger string was seen! Setting up Email Alerts and SNMP Traps After you have created the GPIO and/or Serial Port alerts and traps, you can the use the Serial Device Server internal web pages to set up the recipient Email addresses and/or computer systems.  After you have logged into the internal web pages, click Alerts and Traps on the left side of the screen and select either Email Alerts or SNMP IP Traps. (note that the Alerts and Traps menu item will not appear unless you have previously configured match strings using the Internal Configuration Console as described in the previous section). The Email Alert Configuration screen is shown below.
 Page 36  Silex  Advanced Configuration Part Number 140-00188-180    This screen allows you to define up to eight Email addresses that can receive alert information.  Each address can receive any combination of the alerts that you have defined previously.  You must enter the IP address of your SMTP server and the Email address(es) where you want the alerts to go. For example, in the above screen, the user has configured two serial port match strings.  He has decided to send an alert to the mail address admin@companyxyz.com if the first match string is seen on the serial port. If desired, he could create up to seven more Email addresses that could each receive any combination of these alerts.  The SNMP Trap Configuration page works exactly the same way as the Email Alert Configuration page, except that you enter the Trap Community plus the IP address and port of the destination computer(s) instead of the Email information.  Up to eight separate IP addresses can be configured with any combination of the alerts that you have defined.  Note that you may also use the console command SET IP TRAP n TRIGGER console command (see appendix B) to set up the traps.  When you have finished configuring the alerts, be sure to click the Submit button to save the settings.  You will also need to restart the Serial Device Server in order for the changes to take effect. Using AT Modem Commands The Serial Device Server firmware has an optional data filter for configuring using AT style modem commands with the serial port.  This feature allows devices with an existing AT command interface to configure the unit, if the AT commands can be properly modified.   You must be familiar with the general operation of AT commands. Note that AT command processing is not enabled by default. Use the command SET PORT S1 FILTER AT to enable this feature.  All commands begin with AT and are terminated by a new line unless noted below.  While standard AT commands are defined to be 40 characters or less (not including the AT), the server accepts commands of up to 80 characters. Standard AT Commands Supported The Serial Device Server recognizes a subset of the standard AT command set.  The data channel must be in the command mode for commands to be recognized.  The data channel will be in command mode upon power up or reset.    There are two operating modes for the unit when the AT command option is enabled.  In command mode, data received from the serial port is passed to the AT command processor, and responses are returned to the serial port.  No data is sent to any network application, and any data received from the network is ignored.  In data mode, data from the serial port passes to the network application, and vice versa.  This is equivalent to the normal serial port operating mode without the AT command option.
 Advanced Configuration  Silex  Page 37 Part Number 140-00188-180 Table 8 describes the AT Commands. Table 9 details the Extended AT Commands that allow the configuration of the network server operating parameters.  Any AT command received, except the listed commands, are acknowledged with OK status.  This allows existing modem applications to transmit commands without causing an error.   These include AT<X>n, but not currently AT&<X>n, AT%<X>n, AT\<X>n, where <X> is a letter.   Table 8  AT Commands Parameter Command  Description Enter Command mode  <delay>+++<delay> If the string +++ is seen in data mode, with no characters sent for 1 second before or after, then command mode is entered.   Initiate Connection Command   ATD <destination>   Standard modem dialing command, redefined to initiate an internet connection to a remote computer.  Indicates the IP address of the target, and optionally the TCP port number to use for connection.  The T or  P option (ATDT or ATDP) can be present and has no effect. If present, the IP address must be exactly 12 decimal digits with 3 for each byte of the address.  If no IP address is given, then the ECable destination address defined for the port is used. If the destination TCP port is defined, it is separated from the IP address by a '#' character, and is 1 to 5 decimal digits.   If TCP port is defined, the ECable destination port defined for the serial port is used.  If the destination port is 0, the standard Telnet port (23) is used. If the destination string ends with a semicolon, the server remains in the command mode, not the data mode, once a connection is made.   In command mode data is not passed from the remote computer, so data could be lost if the unit stays in command mode. If the connection cannot be attempted, NO CARRIER status is returned.  If the connection attempt fails, NO ANSWER status is returned.   If the connection succeeds, CONNECT status is returned. Echo control  ATEn  If n=0, commands are not echoed.   If n=1, subsequent commands will be echoed.   The default, upon unit reset, is for no echo (ATE0).  Disconnect  ATHn  If n=0, any connection to a remote host is dropped.  Other value of n is ignored.  Return to data mode  ATOn  Exits command mode and places the serial port in the data mode.   All subsequent data is sent to the network application, if connected, until an enter command mode sequence is received.  Any value of n is ignored, if present.
 Page 38  Silex  Advanced Configuration Part Number 140-00188-180 Parameter Command  Description Quiet mode  ATQn  If n = 1, no result codes are returned.  If n = 0, result codes are returned to the local device. 0 is the reset default value. Verbose mode  ATVn  If n = 0 and not in quiet mode, result codes are returned in numerical form.   If n = 1, results are returned as text.  1 is the reset default value.   Table 9  Extended AT Commands Parameter Command  Description Console pass through  AT#C<string>  Passes the string to the server configuration console. The string can be any valid console command. Refer to your server documentation for console commands available on your unit.   Since this command does not follow the normal AT command format of <command><number>, it must be the last command on the line unless the next command is a '#' command. All characters up to the end of line or a '# will be considered part of the console command. If console quiet mode is not is enabled, then the response will be the standard console task response. Example:  AT#Cset nw ssid silex#Csave Console Quiet mode  AT#Qn  If n = 0,  a  response to a #C command is given.   If n = 1, the response is not provided.  The default after reset is 1.

 Troubleshooting  Silex  Page 41 Part Number 140-00188-180 Chapter 6 Troubleshooting  If you have experience problems with the Serial Device Server, please check the following troubleshooting steps:  1.  Make sure that you are getting power to the Serial Device Server.  The orange LED should be on solid if the proper power is being received.  If it is not on, check the power supply connections, and if possible, try a different Silex Serial Device Server power supply.  2.  Make sure that you have a valid network connection.    a.  Make sure that your network is operating properly (that is, other devices should be able to communicate using the same hub, switch, or access point that the Serial Device Server is connected to).  b.  If you are using hardwired Ethernet, either the yellow LED (for 10Base-T) or the green LED (for 100Base-T) should be lit or blinking.  If they are not, make sure that the cable is properly connected, and if possible, try a different Ethernet cable.  c.  If you are using a wireless connection, both the yellow LED and green LED should be lit or blinking.  If they are not, double check your wireless settings.  The SSID and security parameters must exactly match the requirements of the access point in order for the Serial Device Server to communicate on an infrastructure wireless network.  If you are using Ad-Hoc mode, the Serial Device Server must have exactly the same SSID, security parameters, and RF channel as the other wireless device(s) on the network.  d.  Make sure that you have a valid IP address, subnet mask and router address (check with your network administrator to make sure that you have the correct information).  You can check to see if the IP address information is correctly set by using the ExtendView utility, by printing a test page (press the RESET pushbutton to send a test page to a printer or terminal connected to the serial port) or by using the PING command from a computer system connected to the network.  3.  If you have a valid network connection and IP address, but you cannot communicate with your serial device, then:  a.  Make sure that the settings of the serial port on your device exactly match the settings of the serial port of the Serial Device Server.  For example, if your device is set for 9600bps, 8-bit characters, no parity, and RTS/CTS flow control, the Serial Device Server must also have these exact same settings.
 Page 42  Silex  Troubleshooting Part Number 140-00188-180 b.  If you are using RS-422 or RS-485, make sure that you have set the Serial Device Server’s serial port line mode as described in Chapter 3.  c.  Make sure that have a good cable connection between your serial device and the Serial Device Server.  If possible, try a different cable.  d.  Make sure that the cable pinouts are correct.  In order to communicate properly, the transmit data line on the Serial Device Server must be connected to the receive data line on your serial device, and the receive data line on the Serial Device Server must be connected to the transmit data line on your serial device.  Modem signals, if any, must also be connected so that input signals are connected to output signals and vice-versa.  Refer to the cable diagrams in Chapter 2 of this manual.  e.  Try printing a test page (if your serial device is not capable of directly displaying ASCII character output from the Serial Device Server’s serial port, then disconnect the device and connect a serial printer or terminal to the Serial Device Server).  If the test page prints OK, then the serial port on the Serial Device Server is working properly.  If it does not print, then double check steps 3a, 3b, and 3c.  If none of the above steps solves your problem, then check the Support and Downloads section of the Silex website (www.silexamerica.com).

 Advanced Security Configuration  Silex Page 45 Part Number 140-00188-180 Appendix A  Advanced Security Configuration There are numerous possible security settings.  It is therefore important that you verify the appropriate settings with your network administrator.  If you enter the settings incorrectly, the Serial Device Server will not be able to communicate on your network.  The following table summarizes the wireless settings required for each encryption mode and authentication type:       Authentication Type     802.1x      Open System Shared-Key PSK TTLS LEAP PEAP TLS EAP-FAST Disable (OK) N/A N/A N/A N/A N/A N/A N/A 64-Bit WEP 1 1 N/A N/A N/A N/A N/A N/A  128-Bit WEP 1 1 N/A N/A N/A N/A N/A N/A WPA N/A N/A 2, 3  4, 7 4  4, 5  4, 5, 6 4 WPA2 N/A N/A 2, 3  4, 7  4  4, 5  4, 5, 6 4 WPA2-WPA N/A N/A  2, 3 4, 7  4  4, 5   4, 5, 6 4 Encryption Mode Dynamic WEP N/A N/A N/A  4, 7  4  4, 5   4, 5, 6 4  Wired Ethernet Network  N/A N/A N/A  4, 7  N/A  4, 5   N/A 4                  Basic Configuration Parameters  802.1X Configuration Parameters      1. 64/128Bit WEP Key  4.

Authentication Protocol                     To use the above table, select the encryption mode and authentication type you are using.  For example, if you are using WPA2 with PSK authentication, you would need to set the WPA-PSK pre-shared key and enable or disable the WPA Group Key.  Likewise, if you are using WPA2 with 802.1X TLS authentication, you would need to enter a User ID and Password, an Authentication Certificate, and a Private Key.
 Page 46  Silex  Advanced Security Configuration Part Number 140-00188-180  The following is a description of the authentication settings used by the Serial Device Server:  Encryption Mode (Wireless Security Only) The possible Serial Device Server wireless encryption modes include:  • 64 and 128 bit WEP.  These are available for basic WIFI compatibility.  Because of known security issues, WEP should be avoided if possible. • Dynamic WEP.  Dynamic WEP uses WEP encryption with an 802.1X EAP authentication method.  It is not necessary to set keys with this method, because they are automatically assigned.  • WPA2.  WPA2 is the latest and strongest wireless security standard.  It uses CCMP encryption.  Like WPA, it can be used either with a pre-shared key or with 802.1X authentication. • Wi-Fi Protected Access (WPA). WPA uses TKIP encryption, and can be used with either a pre-shared key (PSK) or with 802.1X authentication. • WPA2-WPA.  This mode combines the capabilities of WPA2 and WPA by using CCMP for pairwise encryption, but allowing TKIP for group encryption.  To set the encryption mode, select the desired mode from the pull down menu on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW ENC <mode>, where <mode> is DISABLE, 64, 128, WPA, OR WPA2.  Note that the encryption mode only applies to wireless networks, so it is not necessary to set this mode if you are using a wired Ethernet network.  Key Selection (Wireless Security Only) This parameter selects which of the four possible WEP keys will be used as the transmit key (the first key is the default). Select the desired key selection from the pull down menu on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW KEY#  n, where n is 1, 2, 3, or 4.  WEP Key Value (Wireless Security Only) Up to four keys can be entered if you are using WEP security.  The value of the keys must be entered as hexadecimal digits (up to 10 hex digits for 64 bit WEP or 26 hex digits for 128 bit WEP). Enter the desired key value(s) on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW KEYVAL <key>, where <key> is 10 hex digits for WEP64 or 26 hex digits for WEP128.  Pre-Shared Key (Wireless Security Only) If you are using WPA2 or WPA with the PSK mode of authentication, the key value or passphrase entered here is used to initialize the session with the access point. If a key value is entered, it must be exactly 64 hex characters. A passphrase must be 8 to 63 displayable characters.  Enter the desired PSK on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW WPAPSK <psk>, where <psk> is the key.  WPA Group Key (Wireless Security Only) If the WPA Group Key mode is enabled, then group keys may be used for data link encryption (the default is disabled).  Select whether to enable or disable the WPA Group Key on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW WPAGROUP <state>, where <state> is ENABLED or DISABLED.
 Advanced Security Configuration  Silex Page 47 Part Number 140-00188-180 Wireless Authentication Type (Wireless Security Only) This parameter sets the type of authentication to be performed with the network access point (Radius authentication server), or with a peer unit in Ad Hoc mode.  The Serial Device Server supports Shared Key and Open System Authentication with WEP, and PSK, TLS, TTLS, LEAP, PEAP, and EAP-FAST with WPA, WPA2, DYNAMIC WEP, and WPA2-WPA. ).  Select the desired wireless authentication type on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW AUTHTYPE <type>, where <type> is OPEN, SHARED, TTLS, PEAP, WPA-PSK, LEAP, TLS, or EAP-FAST.  Wired Authentication Type (Wired Ethernet Networks Only) This parameter sets the type of authentication to be performed with a Radius authentication server on a wired Ethernet network.  The Serial Device Server supports TLS, TTLS, and PEAP authentication on these types of networks.  Select the desired wired authentication type on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW ETHAUTH <type>, where <type> is TTLS, TLS, PEAP, or EAP-FAST.  Authentication Attempts This parameter sets the number of authentication attempts to make before the Serial Device Server assumes the network has no authentication. If zero (0) is entered, the Serial Device Server attempts to authenticate forever.  Enter the number of authentication attempts on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW AUTHTRY n, where n is the number of attempts (default is 0).  User ID This parameter is the logon user ID that the Serial Device Server uses to authenticate to the 802.1x-enabled network. The user ID and password must be in the authentication server database. The default user ID is 'anonymous'.  Enter the user ID on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW ID <user id>, where <user id> is the user ID (the realm can included in the user id with the separator “@”).  Realm A realm defines a grouping of users. If a realm is required for your network, it is separated from the user ID by a '@' character. Among other things, realms make it easier to segregate user groups into independently administered databases, to apply policies on a user group basis, and to establish roaming agreements. The default realm if not specified is 'anonymous'.  Enter the realm on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW REALM <realm>, where <realm> is the name of the realm.  Password This parameter is the logon password that the server uses to authenticate to the 802.1x-enabled network. The user ID and password must be in the authentication server database. The password may be a text string, or a string of hex bytes.  Enter the password on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW PW <password>, where <password> is the password (default value is anonymous).  Authentication Protocol This parameter determines how the server authenticates itself to the 802.1x-enabled network after an 802.1x session is established. The default is PAP; MSCHAP_V2 is the alternative protocol.  Select the desired protocol on the Configure Network Security screen in the Serial Device Server internal web pages, or use the console command SET NW INAP <password>, where <password> is PAP or MSCHAP_V2.  Authentication Certificate Authentication certificates are used by TLS and PEAP.  You can manually enter the certificate information, or you can extract the Root Key and Root Key Exponent from a file on your disk.  The required information is as follows:
 Page 48  Silex  Advanced Security Configuration Part Number 140-00188-180 • Certificate Root Key This is the authentication key used to verify the root certificate in the certificate chain provided by the authentication server. To set to null, send leave this field blank.  Enter the certificate root key on the Configure Authentication Certificate page in the Serial Device Server internal web pages, or use the console command SET NW CERTKEY <value>, where <value> is the value of the key.  • Certificate Root Key Exponent  This value must match the authentication server certificate value. The default is 65537 (x10001). Enter the certificate root key on the Configure Authentication Certificate page in the Serial Device Server internal web pages, or use the console command SET NW CERTEXP <value>, where <value> is the hexadecimal value of the key (default is 10001).  • Certificate Common Name 1 and Certificate Common Name 2  This is the name of the certificate on the primary authentication server (most applications only use a single certificate common name). If both of the common names are set to null, all certificates are accepted. The default is null.  Enter the names on the Configure Authentication Certificate page in the Serial Device Server internal web pages or use the console command SET NW CERTCN <name1> or SET NW CERTCN2 <name2> to enter the two certificate common names, where <name1> and <name2> are the desired names.  Private Key (TLS Wireless Security Only) Private key information or the corresponding public key certificate for the Serial Device Server can be loaded from disk (Private Key Information File) or manually entered.  If the file is encrypted, you must enter the passphrase in the passphrase entry field on the Configure Private Key page in the internal web pages of the Serial Device Server (NOTE: At present, only PEM format files are supported). To manually generate a self-signed certificate for the Serial Device Server, the following information is required:  • Certificate Common Name  • Organization name  • Organization unit  • City name  • State name  • Country name  • Key Size (1024 or 2048)  You may enter this information on the Configure Private Key page in the internal web pages of the Serial Device Server (it cannot be entered via console commands).
  Console Commands  Silex  Page 49 Part Number 140-00188-180 Appendix B  Console Commands The following tables describe the console commands available from the internal command console. Access the command console through the serial port (if enabled for console mode) or over the network using a Telnet session or a web browser.  The console can also be accessed via UART level signals on connector CN5 on the Serial Device Server printed circuit board (this requires you to open the Serial Device Server enclosure and use a special cable; it should only be used by qualified personnel for diagnostic and troubleshooting purposes).

  Firmware Update Procedures  Silex  Page 69 Part Number 140-00188-180 Appendix C Firmware Update Procedures  Occasionally it may be necessary to update the Serial Device Server to take advantage of new features or to fix specific problems.  The simplest way to perform this update is with the Silex UpdateIP utility for Windows XP and 2000 computers.  This utility can be found on the CD-ROM that is included with the Serial Device Server, or it can be downloaded from the Support & Downloads section of the Silex website (www.silexamerica.com).  To use UpdateIP:  1.  Download the appropriate firmware update file from the Support & Download section of the Silex website (www.silexamerica.com) into a directory on your computer. 2.  Download or copy the UpdateIP software files into a directory on your computer. 3.  Double click the updateip.exe icon to start the UpdateIP application.  4. Click OK when you get the About Update for TCP/IP splash screen 5.  When you get the Select Update File screen, locate the firmware update file that you downloaded in step 1, and double click on the file name. 6.  You will get the Update Files screen.  The firmware update file that you selected should appear on this screen.  Click OK. 7.  The program will search the local network for Serial Device Servers. Click OK when the search process is complete. 8.  A list of available Serial Device Servers will appear.  Highlight the Serial Device Server(s) that you wish to update.  9.  From the menu bar, select Update and then Start to update the Serial Device Server(s).  If you cannot use UpdateIP, you can use the trivial file transfer protocol (tftp) to update the Serial Device Server firmware:  1.  Download the appropriate firmware update file from the Support & Downloads Section of the Silex website (www.silexamerica.com) into a directory on your computer. 2.  If you are using Windows 2000, XP, or Vista, enter the following command from the command line of your operating system:  tftp  -i ipaddress  put  filename  access  where ipaddress is the IP address of the Serial Device Server, filename is the file name (and path, if necessary), and “access” is the Serial Device Server password (if you changed this password, use your new password instead of “access”).  For example, to download the file tathsti130.bin from the updates directory on your computer into a Serial Device Server with an IP address of 192.168.5.70, you would enter the command:   Important:  Make sure that the UpdateIP application is included as an exception if you have a firewall enabled on your PC.
 Page 70    Silex  Safety and Regulatory Notices Part Number 140-00188-180 tftp  -i 192.168.5.70  put  /updates/tathsti130.bin  access  If you are using a different operating system, please refer to the documentation of that operating system for information on how to use the tftp command. Note that you should specify that the tftp destination file is the Serial Device Server password (“access” by default).

The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user’s authority to operate this equipment.  Operation is subject to the following two conditions:  (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.  The radiated output power of the print server is far below the FCC radio frequency exposure limits. Nevertheless, print server shall be used in such a manner that the potential for human contact during normal operation is minimized.  To satisfy RF exposure requirements for the SX-500, this device and its antenna(s) must operate with a separation distance of at least 20 centimeters from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter.  End-users must be provided with specific operating instructions for satisfying RF exposure compliance.  The SX-510 satisfies the FCC Part 15C rules for Specific Absorption Rate (SAR).  The SAR limit set by the FCC is 1.6 W/kg (Watts/kilogram).  These limits are part of comprehensive guidelines to establish permitted levels of Radio Frequency energy for the general public.  The highest body SAR value for the SX-510 is 0.41 W/kg.  The SX-510 is not intended for placement next to the head and the 20 cm separation rule should be used.
