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.

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.

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

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.

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.

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.

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

Using the Internal Command Console to Configure the Serial Device
Server
The Internal Command Console is a command line oriented method for configuring the Serial Device
Server. It provides more comprehensive capabilities than either ExtendView or the Internal Web Pages,
but is not as easy to use. Advanced users may prefer to use this method because it is concise, fast, and
powerful.
To use the Internal Command Console:
1. To access the Internal Command Console, enter the following command from the Windows
Command Prompt (MS-DOS Prompt), Mac OS X Terminal Utility, or UNIX/Linux command line:
You may skip this section if you have completely configured the SX-500 using ExtendView or the SX-500 Internal Web

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.

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).
Table 7 describes the Monitor Alert and Trap Configuration Commands.
Table 7 Port Monitor Alert Commands
Command Description
SHOW PORT S1 TRIGMON

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

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.

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).

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.

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.
