1. Overview

The NetBurner SBL2e is a dual serial-to-Ethernet device that will enable your serial device to

communicate on an Ethernet network using TCP or UDP. In addition to the serial capabilities, the

SBL2e also provides a separate network connection command channel for control of digital I/O

signals and analog-to-digital readback. A list of features and functions is below:

2 Serial UARTs, TTL level, baud rates from 300 to 115,200

4 12-bit analog to digital converters, 0-3.3VDC input

Up to 10 Digital inputs/outputs, also referred to as GPIO

10/100 Ethernet

Serial to Ethernet capability through TCP or UDP

DHCP and Static IP addressing

Custom data packetization options

Web page configuration

AT command set configuration and operation

3.3VDC input power @ 250mA max

2. IPSetup Software Utility

Setup and configuration of your SBL2e requires the IPSetup.exe Windows PC utility available for

download at www.netburner.com, in the Support > Public Downloads section:

http://www.netburner.com/support/public_downloads.html

3. Initial Configuration

Before you can begin using your SBL2e, three areas of configuration are required to tell your

SBL2e what type of serial interface you want to use, the network IP address network port number,

and the serial data baud rate.

1. Hardware configuration

2. Network configuration

3. Operational configuration

3.1 Serial Port Hardware

The SBL2e has two asynchronous UART type serial ports, referred to as Port 0 and Port 1. The

SBL2e provides to TTL level UART serial ports:

Port 0 signals : TX, RX, RTS, CTS

Port 1 signals : TX, RX

If you need RS-232 electrical levels, then you must add the appropriate level shifters to the TTL

signals.

The “Debug Serial Port”, or Debug Port for short, is used to display status messages from the

application. If your application needs only a single serial port we recommend setting the other serial

port to “Debug”.

3.2 Network Configuration

1. Run IPSetup.exe (by double clicking its icon). This program is located on the SBL2e product

page at www.netburner.com. To view the Advance Settings, click on the Advanced button (the

button name will change to Basic). In this example, I am using Uart 1 as my Monitor port

(screen shot below).

2. Locate your SBL2e in the "Select a Unit" pane by matching its MAC address. The MAC

address is located on the bottom of your SBL2e. If your SBL2e device does not appear in the list

box, verify the power, speed, and link LEDs are illuminated, and click the Search Again button.

If you are still unable to see your SBL2e, remove power, correct any cabling errors, reapply

power, and click the Search Again button. Note: IP Setup uses a UDP broadcast protocol and

will not operate through a router.

FIREWALLS: IPSetup uses UDP and TCP port number 20034. If your computer’s

firewall is blocking this port number you will need to either disable the firewall, or add a

rule to the firewall to allow communication on this port number.

3. If your network supports DHCP (factory default): The assigned IP Address will appear in the

"Select a Unit" pane. Write down this address. If your network does not support DHCP,

configure the IP Address and Network Mask fields as shown in the screen shot below. If you

need help selecting values, please read the "Selecting an IP Address" section at the end of this

guide. After you have entered all of your values, click the Set button in the center of the IP

Setup window to configure your SBL2e with its new parameters. Note: If you do not click the

Set button, your values will not be saved. If you have multiple NetBurner devices, make sure

you selected your SBL2e in the "Select a Unit" pane (as shown in the screen shot) before you

input your information.

3.3 Operational Configuration

Once the network parameters are, you can use the web server interface or serial AT commands to

modify the settings of your SBL2e. We recommend using the web interface first to familiarize

yourself with the operation of the SBL2e. To access the web page, click on the Launch Webpage

button in IP Setup, or you can open your web browser, and enter the numeric IP Address in the

address field (e.g. http://10.1.1.110).

4. Web Page Configuration

Once you have configured the IP address of your device you can connect to the SBL2e web server

to configure your serial and network settings. The SBL2e can be configured in one of 3 modes:

1. TCP Server: Listen for incoming TCP connections.

2. TCP Client: Connect to a target network address when serial data is available, or you can

also establish a network connection on SBL2e power-up.

3. UDP: Send and receive using UDP packets

4.1 Network IP Settings Configuration

The first section of the Network Configuration page is used to select DHCP or static IP addressing.

If you select DHCP, and the you have a DHCP server on your network, the DHCP assigned values

will be displayed. To select a static IP address chance the Address Mode to Static, and enter your

values in the Static Settings fields.

Device Name

Specifies the device name to send to your DHCP server.

Address Mode

Select between DHCP and Static IP address settings.

Device IP Address

Device Subnet Mask

Device Gateway

Device DNS

If Address Mode is set to DHCP, your DHCP server will provide these

values and they will be displayed in the DHCP Assigned Values column.

If you wish to specify these values yourself set the Address Mode to

“static” and type the values in the appropriate fields. Note that if you do

not specify a Gateway or DNS server you will not be able to communicate

outside your LAN.

Ethernet Link

Normal = Auto-negotiate. You may also force 10MB or 100MB modes.

4.2 Incoming Connections (Server Mode)

This section configures the SBL2e in a device server mode in which it listens for incoming TCP

connections (or UDP packets if enabled) for each serial port.

Listen for incoming network

connections

Select checkbox to enable the port to listen for

incoming TCP connection requests or UDP packets.

Checking this box will override the TCP Client mode.

Listening network port

Port number to listen on. The default port is 23 (telnet).

The listen port numbers for Port0 and Port1 must be

different.

Timeout and disconnect after this many

seconds of inactivity.

Terminate TCP connection if no incoming network

data or outgoing serial data has occurred. This is useful

because there is no way to detect if a client has crashed

or abnormally terminated unless unacknowledged data

exists and times out. A value of 0 disables this feature.

This field has no effect in UDP mode.

Allow new connection if the existing

connection has been idle for this many

seconds.

Similar to the disconnect timeout, but does not

disconnect a connection until a new connection is

requested. A value of 0 disables this feature. This field

has no effect in UDP mode.

SBL2e Dual Serial-to-Ethernet User's Manual Page 9

4.3 Outgoing Connections (Client Mode)

Make outgoing connections

Selects between connect on power-up for a permanent

TCP connection, or make a TCP connection when

serial data available. This feature has no effect on

UDP.

Connect on network port

Specifies destination TCP or UDP port number

Connect to this address

Specifies destination IP address for TCP or UDP.

When using UDP you must specify an address and port

number in this section, or enable the Learn UDP Reply

Address feature in the Custom Packetization section.

Timeout and disconnect after this many

seconds of inactivity.

Terminate TCP connection if no incoming network

data or outgoing serial data has occurred. This is useful

because there is no way to detect if a client has crashed

or abnormally terminated unless unacknowledged data

exists and times out. A value of 0 disables this feature.

This feature has no effect on UDP.

Retry failed outgoing connections after

this many seconds.

Number of seconds to wait before retrying an outgoing

connection. This feature has no effect on UDP.

4.4 Custom Packetization

Custom packetization can apply to TCP and UDP communication. Unlike TCP, UDP is a

connectionless protocol. The SBL2e provides two methods to determine the destination network IP

address: you can specify a static IP address, or you can use the source IP address of the last received

UDP packet by selecting the “Learn UDP Reply Address” checkbox.

Use custom packetization logic

Enables/disables custom packetization settings

Use UDP instead of TCP

Check to enable UDP

Learn UDP reply Address

Send outbound serial to the IP address from the last

received UDP packet. Useful for clients that may have

changing IP addresses. If not using this feature, you

must specify the destination IP address and port

number in the Outgoing Connections section.

Number of characters to accumulate

before sending TCP/UDP packet

Maximum number of characters to accumulate from

the serial port before sending them out the network

port. This setting will be overridden if the

accumulation delay time setting is used and the delay

time expires.

Number msec to wait for accumulated

characters (0 waits forever)

Maximum wait time in milliseconds for received serial

characters before sending any available characters out

the network port.

Flush TCP frame when this character is

received (Enter NA to disable)

Send all accumulated serial data upon receipt of this

character from the serial port. Enter the decimal value

of the character. For example, a line feed is 10.
