Chapter 1: Introduction The SX-550 embedded intelligent module provides a complete solution for integrating wireless or wired networking technology into virtually any OEM product that has an RS-232 or UART serial port. It can also be used as an Ethernet to 802.11 bridge to enable wireless capabilities on devices that have an Ethernet interface. It is available in two models: • SX-550-0700 Ethernet model. The SX-550 Ethernet model consists of a printed circuit board (processor card) that measures 44.
Figure 1 SX-550-1701 (left) and SX-550-2701 (right) The SX-550-1701 and SX-550-2701 are virtually identical in form and functional identical, with a few minor differences. The one major difference is the SX-550-2701 includes FCC modular approval (see Appendix D). Other differences include: • • • • • • • • • • International roaming (802.11d) is a standard non-configurable feature of the SX-5502701, so there are no corresponding configuration items.
Chapter 2 Installing the Evaluation Daughtercard The SX-550-6900 Evaluation Daughtercard is designed to help you in the development of the necessary hardware and software required to use the SX-550 module. It includes I/O connectors, cables, and power supply in an easy-to-use package. The SX-550 Module is installed in the Evaluation Daughtercard as shown in Figure 2.

Electrical Characteristics The power requirements, port pinouts, GPIO characteristics, cable connections and wireless operational modes are described below. Power Input Power to the SX-550 Module and the SX-550-6900 Evaluation Daughtercard is supplied through the power jack, located at J4, at +5VDC ±10%. Use the included power supply or an equivalent +5VDC power supply with a minimum of 1 amp capacity. Power of +3.3VDC ±5% is input to the SX-550 Module via the OEM header, J5.
Using the Optional Serial Signals Signals GPIO 1 to 6 can be used as GPIO or Serial Port control signals DTR, DSR and DCD. To configure signals DTR, DSR and DCD, place a jumper between JP4 and JP5 for that signal, as shown in Figure 5. 1 O I P G 1 R T D 2 O I P G 1 R S D 3 O I P G 1 D C D 4 O I P G 2 R T D 5 O I P G 6 O I P G 2 R S D JP3 JP4 JP5 2 D C D Figure 5 Optional Serial Signals To select the GPIO signals, place the jumper between JP3 and JP4. The GPIO signals are available at JP7.
General Purpose I/O The GPIOs, located on JP7, can be used for controlling or monitoring OEM functions. External pull-ups are recommended for customization. NOTE: GPIO 7 is fixed as a switch input (Test Button) and GPIO 8 is fixed as an LED output (Power).

Chapter 3 Configuring the SX-550 IMPORTANT: This chapter assumes that you are either using the SX-550-6900 Evaluation Daughtercard or that you have made the appropriate connections to the SX-550 module OEM Header. Refer to Chapter 2 and Chapter 5 for information on connecting to the SX-550 hardware. This chapter describes the methods for configuring the basic settings of the SX-550, including the IP address, serial port settings, and wireless security.
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 • Character Size • Flow Control In addition to the above parameters, the SX-550 allows you to configure numerous other capabilities.
Using the ExtendView Utility to Configure the SX-550 (Ethernet Connection) NOTE: Skip this section if you do not have a Windows PC or if you do not have an Ethernet connection to the SX-550. The ExtendView Utilty is the easiest way to initially configure the SX-550 from a Windows PC because it allows you to directly set the IP address into an unconfigured SX-550, and it allows you to view the IP addresses of all of the SX-550s on your network. It has limited capabilities for configuring 802.
3. Right-click on the SX-550 that you want to configure from the displayed list, and then leftclick on Configuration. The default SX-550 name is SDSxxxxxx (where xxxxxx is the last six digits of the MAC address from the label that is affixed to the SX-550). 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.
6. Click the Wireless tab to configure the 802.11a/b/g wireless settings (for wireless models only; skip to the next section if you have a wired model). To operate on an 802.11a/b/g network, the SX-550 configuration must be configured with the wireless configuration and security parameters necessary for the SX-550 to communicate over your wireless network (check with your network administrator if you do not know these parameters).
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 SX-550 to these settings Click OK when you are finished to return to the Server Configuration window and then click OK again. 10.
task one time -- once the address has been configured, the SX-550 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 SX-550: a. Make sure your PC is connected and has access to your network. b.
address (for example, 00-0017-00-00-01). You will see a reply from the SX-550 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 SX-550 may not be at its default configuration. To reset the SX-550 to its default settings, hold down the test button on the Evaluation Daughtercard for more than five seconds.
Using a Web Browser to Configure the SX-550 You may skip this section if you have completely configured the SX-550 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. After you have entered an IP address into the SX-550, you can use any standard web browser to access the internal web pages for configuring the SX-550.
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 6 for advanced configuration information. Note that on-line help information is available on every configuration page.
configure the wireless security parameters. 5. Select the appropriate wireless encryption mode and enter the required settings (check with your network administrator for the proper settings if you do not know them). Appendix A lists the possible encryption settings. Click the Submit button at the bottom of the window (you may need to scroll) to save your changes. Now click I/O Port on the left side of the screen to configure the serial port. 6.
2. When the SX-550 is powered on, you will see some information about the firmware versions and copyright notices displayed on the terminal. When you see the Local> prompt, you can enter commands. The SX-550 is set by default to use DHCP to obtain the IP address automatically. If you want to set the IP address manually, enter the following commands: SET IP ADDRESS aa.bb.cc.dd SET IP SUBNET aa.bb.cc.dd SET IP ROUTER aa.bb.cc.dd where aa.bb.cc.dd is the IP address of the SX-550.
SET PORT S1 FLOW [where is NONE, XON/XOFF, CTS, or DSR] The console commands are summarized in Appendix B of this manual. 6. When you have finished entering commands type: INIT EXIT These commands will save the configuration and restart the unit. You are now ready to use the SX-550. IMPORTANT: EXIT The console command EXIT must always be used in order to save the changes you made with the internal command Console. 7.

Chapter 4 Using the SX-550 with Your Application The SX-550 includes a number of capabilities that enable it to be used in a wide range of applications. These capabilities include: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12.
Customizing the SX-550 User Interface The SX-550 user interface can be customized to include your company’s name or other information. For example, instead of displaying Silex SX-550 on the internal web pages and the internal command console interface, the SX-550 could display Company XYZ. In addition, the 3-character OEM code used in the SX-550 server name and service names can be changed from the default code SDS to a userdefined code.
After the Serial Port Emulator software has started, you will see a list of all the configured SX-550s on the network. Right click on the name of the SX-550 that you want the virtual COM port to connect to (the default name is SDSxxxxxx, where xxxxxx is the last six digits of the SX-550 MAC address), and then click Virtual Port. You will be asked to select the name of the virtual COM port (for example, COM3).
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 where ipaddress is the IP address of the SX-550 and portnumber is the SX-550 TCP port number. For example: telnet 192.168.5.
To set E-Cable mode, use a web browser to access the SX-550 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 SX-550) 3.
Print Server Mode You can use the SX-550 as a standard TCP/IP print server, which is very useful if you are connecting the SX-550 to a serial printer. The SX-550 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 SX-550 as the printer’s address or host name.
Once you are connected in console mode, you can send any of the console commands listed in Chapter 6. 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 SX-550 allows you to control the serial port using standard AT modem commands.
Bridge Mode The SX-550 can work as a transparent bridge from Ethernet to 802.11a/b/g. This is useful for allowing a device that have an Ethernet interface to be used on a wireless network. Operation is totally transparent, so there is no modification required to the device’s software or firmware. Bridge mode MUST be enabled through the Internal Command Console. To do this, connect to the console as described in Chapter 3 and enter the following commands at the Local> prompt.
Chapter 5 Interfacing the SX-550 to the OEM Device In order to connect the SX-550 module to your device, you will need to provide either a custom daughtercard or a special cable. Both of these solutions will require a 40-pin female connector on one side, with the appropriate connector(s) for connecting to your device’s circuitry on the other side. The custom daughtercard is generally a superior solution because it provides better mechanical connections for greater overall system reliability.

OEM Header Interface The OEM Header Interface is the primary method for communications between the SX-550 and your device. It includes the necessary pins for serial data I/O, GPIO, and power. Table 12 describes the OEM header interface pinout for the SX-550 module. Table 13 shows the OEM interface signal descriptions. All input and output signals, except the differential signals, are 0 to 3.3V logic signals.

IMPORTANT: In order to prevent flexing of the SX-550 boards during the installation process, you must use spacers. Silex provides spacers on the SX-550-1701 and SX-550-2701 WLAN models that go between the base module board and the radio module board. However, because of the wide range of possible OEM daughtercard connectors and other design issues, you must provide the three spacers that go between the SX-550 base module board and your daughtercard.

Table 21 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 SX-550 module is PUBLIC. Table 21 SNMP Commands Command GET Description Retrieves management information for a specific managed object contained in the agent. The GET message must contain the OID for the specified object.
Figure 11 SNMP Configuration 8. Click the Submit button to save the changes. You must then restart the SX-550 to make the changes take effect. Configuring the General Purpose I/O (GPIO) Lines The SX-550 module has eight General Purpose I/O (GPIO) lines available for use on connector J7. These GPIO lines are individually programmable for either input, output, or special purpose. By default, six of the GPIO lines are configured for special purpose use.
Table 22 GPIO General Commands Command SET GPIO DIR [IN|OUT] GPIO # = {1|2|3|4|5|6|7|8} Description Sets GPIO signal to be an input or an output. The setting only takes effect if the GPIO signal is not selected for special function operation. must be in the range 1-8. Note: is 7 for GPIO_9 and 8 for GPIO_10 (GPIO_7 and GPIO_8 are not settable by the user) NOTE: The direction bit configuration is not changed by a configuration reset to default.
SET GPIO DIRM GPIO # = {1|2|3|4|5|6|7|8} Sets all direction control bits, where is an 8 bit mask expressed as 2 hex digits. This value should be in the range 00-FF. The mask is encoded as follows: 7 6 5 4 3 2 1 0 GPIO10 GPIO9 GPIO6 GPIO5 GPIO4 GPIO3 GPIO2 GPIO1 A value of 1 sets the corresponding GPIO line to be an output. A value of 0 sets the GPIO line to be an input. For example, a hex value of 80 sets GPIO8 as an output, all other GPIO signals are input.

Table 23 GPIO Trigger Commands Command SET GPIO TRIGger [1 | 0| DIS] Description Sets a single control bit. The setting only takes effect if the GPIO signal is not selected for a special function operation and is configured to be an input. The parameter after the TRIG keyword controls the operation as follows: Enable trigger if the specified GPIO signal transitions from a 0 to a 1.
Command Description Local> set gpio trig 1 1 Local> set gpio trig 0 2 Local> show gpio trig GPIO Trigger Conditions ----------------------trig if GPIO #1 is 1 trig if GPIO #2 is 0 GPIO #2 is set for OUTPUT GPIO #3 is set for OUTPUT SET GPIO TRIGM Sets all trigger control bits. is a 32-bit mask expressed in hex digits.
Command Description Example: Local> set gpio trigm 00040006 Local> show gpio trigm GPIO trigger mask = 00040006 SET GPIO TRANsmit Sets the string that will be included in an Email alert if the trigger is activated. These strings are also used to identify the trigger on the trap and alert web pages. This value overrides the default string created when the trigger is enabled, which is of the form “GPIO # is 0|1>”.
Table 24 GPIO Transmit Commands Command Description SHOW GPIO TRANsmit SHOW GPIO TRANsmit Displays the string that will be included in an Email alert if the trigger is activated. These strings are also used to identify the trigger on the trap and alert web pages. There are two forms -- one displays all strings, the other only shows the string corresponding to a specific trigger. NOTE: GPIO #7 in this display is actually GPIO_9, while GPIO #8 is actually GPIO_10.
Command SET GPIO DATA Description Sets all the data out control bits. is an 8 bit mask expressed as 2 hex digits. This value should be in the range 00-FF. The mask is encoded as follows: 7 6 5 4 3 2 1 0 GPIO10 GPIO9 GPIO6 GPIO5 GPIO4 GPIO3 GPIO2 GPIO1 Each GPIO output bit is set to the corresponding value in the mask. If a GPIO signal is set as an input, the value is set but has no effect. If a GPIO signal is set for a special function, the bit value give is ignored.
Table 26 E-GPIO TCP Monitor Commands The E-GPIO TCP monitor allows a computer system to access the SX-550 GPIO pin values. If enabled, this monitor will attempt to make a TCP connection to the remote computer specified. Once connected, the monitor will periodically send the state of the GPIO pins to the remote computer.
GPIO set message format This message may be optionally sent by the remote computer when an E-GPIO connection is active. This message allows the remote computer to set the state for any GPIO pins configured as ouptus. This is equivalent to the SET GPIO DATA command. The message is in the format: GPIO=00ab Where ab are 2 hex digits representing the state of the GPIO pins. Since there are only 8 GPIO pins on the SX-550, the first two digits should always be 0.
GPIO direction control Integer read-only gpio.2 This is an integer representing a bit mask indicating which GPIO bits are configured for outputs. Only bits for which the GPIO bit mask is 1 are valid. A 1 indicates the GPIO bit is an output, a 0 indicates an input. 7 6 5 4 3 2 1 0 GPIO10 GPIO9 GPIO6 GPIO5 GPIO4 GPIO3 GPIO2 GPIO1 GPIO data Integer read-write gpio.2 This is an integer representing a bit mask indicating the GPIO bits status. On a read, the current value of the input pins is returned.
GPIO transmit string value Octet-string read-only gpio.5.1.2.n This item returns the GPIO transmit string for trigger number n, if a string is defined. The string may be defined even if the corresponding trigger is not currently enabled.
Configuring Serial Port Monitor Alert and Trap Configuration The SX-550 module can be configured to scan and compare the data received on the serial port to userdefined 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. Table 28 describes the Monitor Alert and Trap Configuration Commands..
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 SX-550 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. The Email Alert Configuration screen is shown below.
Standard AT Commands Supported The following standard AT commands are interpreted by the device server. 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.
Parameter Echo control Command ATEn Description 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.

TCP Port Connections The SX-550 module supports port connections over TCP/IP using raw TCP ports only. Table 34 describes the TCP ports allocations.
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 SX-550 will not be able to communicate on your network.
Encryption Mode (Wireless Security Only) The possible SX-550 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.
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 SX-550 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. ).
• 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 SX-550 internal web pages, or use the console command SET NW CERTKEY , where is the value of the key. • Certificate Root Key Exponent This value must match the authentication server certificate value.
