Installing the SX-560 Module
To install the SX-560 module in the SX-560-6900 Evaluation Daughtercard:
1. Using the 40-pin OEM interface header (JP2), plug the SX-560 Module in the SX-560-6900 Evaluation Daughtercard and secure with screws, nuts and spacers (you may optionally use the metal retaining bracket to secure the radio card and to reduce electromagnetic interference; refer to Chapter 5 for information on using this bracket). Important: The spacers MUST be installed to avoid
potential damage to the boards.
Figure 3 SX-560 Module Inserted in Daughtercard
2. The Evaluation Daughtercard includes both on-board bead antennas and external antennas. Use the included U.FL to U.FL cables with the bead antennas or the U.FL to RP-SMA cables with the external antennas. Plug the main antenna cable into the Main Antenna Connector on the card (see Figure 3). Plug the auxiliary antenna cable into the Auxiliary Antenna Connector (the auxiliary antenna improves radio reception, but is not required for operation).
3. If you are using the on-board bead antennas, connect the other end of the antenna cable(s) into either of the built-in bead antenna connectors (J7 and J8) as shown in figure 3. If you are using the external antennas, connect the RP-SMA end of the antenna cable(s) to the external antenna(s).
4. Connect one serial null-modem cable from the Serial Port 3 DB-9 connector (J5) on the Evaluation Daughtercard to a serial port on a personal computer or laptop (the computer’s serial port must be set to 115.2Kbps, no parity, no flow control, and 8-bit character size). The PC or laptop acts as a console port for command line configuration and monitoring.
5. If you want to use an Ethernet LAN connection for the initial configuration of the SX-560 (recommended), plug a category 5 Ethernet cable into the RJ-45 jack. The Ethernet interface has Auto-MDIX that automatically detects and configures itself for either a straight-thru or crossover Ethernet cable.

OEM Interface
The OEM interface is a 40-pin header (JP2) that is used to connect the SX-560 module to the SX-560-6900 Evaluation Daughtercard. It will also serve as the primary means of communications between the SX-560 and your OEM device (refer to Chapter 5 for information on using this header to connect with your device).
Table 3 shows the OEM interface pinout for the Evaluation Daughtercard. Table 4 shows the OEM interface signal descriptions. Please note that the OEM interface signals are not directly accessible from the OEM header when the Evaluation Daughtercard is used. Rather, these signals are available through convenient connectors on the Evaluation Daughtercard, such as the 26-pin I/O Header and the 9-pin serial connectors. These connectors are described later in this chapter.
All input and output signals, except the differential signals, are 0 to 3.3 V logic signals.

Electrical Characteristics
The power requirements, port pinouts, GPIO characteristics, cable connections and wireless operational modes are described below.
Power Input
Power to the SX-560 Module and the SX-560-6900 Evaluation Daughtercard is supplied through the power jack, located at J6, 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 supplied to the SX-560 Module via the I/O header, JP13.

Part Number 140-00192-100
Power Management
The SX-560 power consumption is typically 280mA for wireless-to-serial usage, with a peak consumption is 400mA @ 3.3V. In powersave mode (refer to Chapter 4 for more information) with the SX-560 connected wirelessly to an access point, the consumption is 60mA while idling and an average of about 73mA including wakenings to answer the beacon poll.
The above numbers assume that the only active connections are the 802.11 wireless interface and the serial interface (for example, there are no connections to the GPIOs). Power consumption specifications are subject to change; contact Silex for more information.
Serial Ports
Standard serial RS-232 signals are available on the DB-9 male connectors J3, J4 and J5 for Serial Ports 1, 2 and 3 (Serial Port 3 is dedicated as a console port, while Serial Port 2 can be set as either a console port or an I/O port), as shown in Figure 4. Serial Ports 1 and 2 include the RTS and CTS modem signals for hardware flow control, and Serial Port 1 can also support DCD, DTR, and DSR by setting the appropriate jumpers on the JP9 header (see the Using the GPIO Special Functions section later in this chapter). Serial Port 3 does not support any modem signals, and is fixed for operation at 115.2Kbps, no parity, no flow control, and 8-bit character size.
The DB-9 connectors use industry-standard PC-compatible pinouts as shown below:

3.3V
All signals are 0 to 3.3 V logic signals.
The console port (Serial Port 3) can be also be accessed via the 26-pin I/O header pin headers (pin 19 for TxD and pin 22 for RxD). The console port is normally set to use the DB-9 connector; to use the 26-pin I/O header, remove the jumper on the header at JP11 so that two sources are not driving the RXD2 signal.
Note that Serial Port 3 is dedicated for use as a console port for configuring the SX-560. Serial port 3 is always set for operation at 115.2Kbps, 8 bit character size, no parity, and no flow control.
Serial Port 2 is set by default for console operation at 115.2Kbps, 8-bit characters, no parity, and no flow control. This port can be set as a second I/O port using the SET PORT S2 CONSOLE DISABLE console command.
RS-232 Cable
The supplied DB-9 female-to-female null modem cable is wired as shown below. The pinouts are compatible with a standard PC 9-pin serial connector, so this cable can be used to directly connect a PC to Serial Port 3 for use as a console terminal to configure the SX-560. It can also be used to connect many types of OEM serial devices to Serial Port 1 or Serial Port 2, provided that these devices use PC­compatible 9-pin connectors.

Using the GPIO Special Functions
Six of the General Purpose I/Os (GPIOs) can be configured for either user-defined operations or for GPIO for special functions. These special functions are summarized in the following table:
Table 8 GPIO Special Functions

GPIO_7
GRN
Green status LED (D10) GPIO_8
YEL
Yellow status LED (D9)
The mode of operation for each of the GPIOs can be set by installing jumpers between headers JP7 and JP8 for GPIO operation, or between headers JP8 and JP9 for special function operation (all of the special functions are enabled by default). For example, in the follow diagram, GPIO_3 is enabled for SPI temperature sensor, while GPIO_4 is enabled as the DTR signal (DTR0) for Serial Port 1. The GPIO_5 through GPIO_8 are used as normal GPIOs in this example.

The GPIOs are accessed via header JP3 as described in the next section. You can set and read the GPIO state, and set Email alerts and SNMP traps based on the GPIO state as described in Chapter 6 of this manual.
26-Pin I/O Header
The I/O Header, located at JP3, is a 26-pin interface for connecting to the SX-560 GPIO and SPI interfaces. It also provides a direct way of connecting to the SX-560 console interface using 3.3V logic levels rather than the DB-9 RS-232 connector.
The GPIOs, located on JP3, can be used for controlling or monitoring OEM functions. External pull-ups are recommended for customization.

As discussed in the previous section, GPIOs 3 through 8 are set by default for special functions such as modem controls. To use GPIOs 3 through 8 as normal GPIOs, you must place a jumper between JP7 and JP8 for the specific GPIO as described in the previous section. GPIO 2 can also have a special function if SPI mode is selected for the LCD display via header JP12 as described in the LCD Interface section later in this chapter.

USB Host Port and Ethernet Port
The USB V1.1 host port, located on J1, can be used to connect standard Full Speed (12Mbps) or Low Speed (1.5Mbps) USB devices. High Speed (480Mbps) is not supported.
The USB port is disabled by default. To enable it, remove the jumpers on headers JP4 and JP5 as shown below.

Figure 7 USB/Ethernet Jumper Settings
Ethernet Port
The Ethernet port, located on J2, can be used for configuring and testing the SX-560. Ethernet provides an easier way to do the initial setup and configuration of the SX-560, because you do not have to worry about wireless security configuration parameters. Operation of the SX-560 through this port is identical to wireless operation, except that wireless security is not supported. Ethernet is enabled by default (see previous section for information on jumper settings).
Note that because the Ethernet port is connected through the USB host port, it cannot be used at the same time as the USB port. Also, when the Ethernet port is used, the 802.11a/b/g wireless port is disabled.
Additional OEM Interface Signals
The output LED signals ORLED-, GRLED- and YELED- represent the state of the LEDs on the module. Logic 0 indicates the LED is on, and Logic 1 indicates the LED is off. Buffers are recommended if LEDs are to be driven on the end-user side.
The SWITCH signal is connected to a momentary pushbutton switch (Test Button) on the Evaluation Daughtercard and is in the normally open position. Depressing the switch causes a short to ground. A
4.7 K-ohm pull-up resistor to +3.3 VDC is connected. The module’s processor monitors this signal. The
end-user can drive or use open-collector to this signal to either logic level or can monitor this signal as an input. The Test Button is normally used either to send configuration information to a printer (button momentarily pressed) or to reset the SX-560 to its default configuration (button held down for more than 5 seconds).
Serial Peripheral Interface
The four SPI signals are accessible using the 26-pin I/O header JP3. The SPI MOSI, SPI MISO, and SPI Clock signals are routed to both the JP3 header and an on-board temperature sensor. The temperature sensor can be disabled by removing the jumper from the TSPICS signal on JP7 as described in the GPIO Special Functions section above.
IMPORTANT: Do not plug a USB device into the USB port if the Ethernet port is enabled.

LCD Interface
A 16x2 LCD display is available as an option for the SX-560-6900 Evaluation Daughtercard. This LCD can be controlled from either Serial Port 2 or via the SPI interface. The LCD display plugs into header JP1. Header JP12 is used to select serial or SPI control (place a jumper on pins 1 and 2 to select serial, or place the jumper on pins 2 and 3 to select SPI).

Chapter 3
Configuring the SX-560
This chapter describes the methods for configuring the basic settings of the SX-560, including the IP address, serial port settings, and wireless security. The SX-560 also has an extensive range of advanced configuration capabilities that are described in Chapter 6, Appendix A, and Appendix B. The SX-560 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 SX-560, 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)
• 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.
IMPORTANT: This chapter assumes that you are either using the SX-560-6900 Evaluation Daughtercard or that you have made the appropriate connections to the SX-560 module OEM Header. Refer to Chapter 2 and Chapter 5 for information on connecting to the SX-560 hardware.
Page 20

Using the SX-560
Part Number 140-00192-100
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-560 allows you to configure numerous other capabilities. These other capabilities provide you with the unparalleled flexibility to use the SX-560 on virtually any
802.11a/b/g network with virtually any RS-232 serial device.
Initial Wireless Setup
If you are using a wireless network connection for the first-time configuration of the SX-560, you must set up a temporary ad hoc wireless connection as described in the following steps.
1. Disconnect your PC and the SX-560 from your network, and temporarily change 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
• Make sure that all network security is disabled.
2. Power on the PC and the SX-560. You can connect to the SX-560 by specifying its default IP address of 192.0.0.192 using the ExtendView utility or a web browser as described in the next sections. After you have connected, you can use ExtendView, the internal web pages, or the internal console to change the SX-560 configuration as follows:
a. Enable AUTO as the boot method or IP address resolution method on the SX-560, or
manually change the IP address to the one you will actually be using on your network.
b. Enter the required wireless networking parameters on the SX-560 for operation on your
wireless network (for example, SSID, mode, and wireless security).
c. Change the serial port settings to match those of your device.
3. After you complete the entire SX-560 configuration process:
a. Set your PC back to its original network settings, and restart it.
b. Restart the SX-560. The new settings will take effect after the SX-560 has restarted.
Configuration Methods
There are three ways to configure the SX-560:
• ExtendView. ExtendView is a simple Graphical User Interface configuration program for Windows. It has the advantage of allowing you to perform bulk configuration of multiple SX-560s simultaneously. If you are using a wired Ethernet connection with the SX-560-6900 evaluation daughtercard, ExtendView also lets you set the IP address and wireless network settings into an unconfigured SX-560 device server (if you are using a wireless network connection for connection, then you must first configure the IP address and wireless network settings using the
NOTE: Skip this section if you are using the Ethernet port on the SX-560-6900 Daughtercard for the configuration process, or if you are using a terminal connected to one of the serial ports on the SX-560.
Configuring the SX-560

Initial Wireless Setup procedure described previously in this chapter, or the internal command console.
• Internal Web Pages (HTTP). You can use any standard web browser to access the SX-560 internal web pages. These web pages provide an easy-to-use graphical interface for configuring the SX-560. In order to use the internal web pages for the first time, you must assign the SX-560 IP address and wireless network settings using some other method (for example, the Initial Wireless Setup procedure described previously in this chapter, or the internal command console). 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 SX-560. It can be accessed by connecting a serial cable to serial port 2 or serial port 3 (serial port 1 can also be used to access the internal command console by sending the AT#C command or defining a console mode string as described in Chapters 4 and 6). Once the IP address and wireless network settings have been configured, the internal command console can also be accessed via TELNET, or via ExtendView and the internal web pages.
Configuring the SX-560 using each of the above methods is described in the following sections of this chapter.

Using the SX-560
Part Number 140-00192-100
Using the ExtendView Utility to Configure the SX-560 (Ethernet Connection)
The ExtendView Utility is the easiest way to initially configure the SX-560 from a Windows PC because it allows you to directly set the IP address into an unconfigured SX-560 if you are using the SX-560-600 evaluation daughtercard Ethernet port, and it allows you to view the IP addresses of all of the SX-560s 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 Evaluation Daughtercard, or it can be downloaded from the Silex website. To install ExtendView, simply follow the on-screen installation instructions and then restart your computer when the installation procedure is complete. The SX-560 configuration procedure is as follows (please note that the screens may be slightly different than shown, depending on the SX-560 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 prefer to use the internal web pages or internal command console for configuration.

Part Number 140-00192-100
3. Right-click on the SX-560 that you want to configure from the displayed list, and then left­click on Configuration. The default SX-560 name is SDSxxxxxx (where xxxxxx is the last six digits of the MAC address from the label that is affixed to the SX-560).
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 6 for information). This advanced configuration can be done at a later time, however.
NOTE: If you are using DHCP on your network, the SX-560 should have acquired valid IP settings at this point and no further IP address configuration is necessary. However, for some installations, a static IP address is preferred. If your DHCP server does not allow the SX-560 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.

6. Click the Wireless tab to configure the
802.11a/b/g wireless settings. To operate on an 802.11a/b/g network, the SX-560 configuration must be configured with the wireless configuration and security parameters necessary for the SX-560 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 6 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 WPA­PSK, 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 serial port 1.
