devices.
XPort Direct+ User Guide 10
Protocol Support
The XPort Direct+ device server uses the Internet Protocol (IP) for network
communications. It uses the Transmission Control Protocol (TCP) to assure that no
data is lost or duplicated, and that everything sent to the connection arrives correctly
at the target.
Supported protocols include:
ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for
network communications and management.
TCP, UDP, and Telnet for connections to the serial port.
TFTP for firmware and web page updates.
IP for addressing, routing, and data block handling over the network.
User Datagram Protocol (UDP) for typical datagram applications in which
devices interact with other devices without maintaining a point-to-point
connection.
SMTP for email transmission.
2: Introduction
Addresses and Port Numbers
Hardware Address
The hardware address is also referred to as the Ethernet address or the MAC
address. The first three bytes of the Ethernet address are fixed and read 00-20-4A,
identifying the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique
numbers assigned to each unit.
Example: 00-20-4A-14-01-18
Note: Make note of the MAC address. It is needed to locate the XPort
Direct+ using DeviceInstaller.
IP Address
Every device connected to an IP network must have a unique IP address. This
address is used to reference the specific unit. The XPort Direct+ is automatically
assigned an IP address on DHCP-enabled networks, as it is DHCP-enabled by
default.
Port Numbers
Every TCP connection and every UDP datagram is defined by a destination IP
address and a port number. For example, a Telnet application commonly uses port
number 23. A port number is similar to an extension on a phone system.
The unit's serial channel (port) can be associated with a specific TCP/UDP port
number. Port number 9999 is reserved for access to the unit's Setup (configuration)
Mode window. Ports 0-1024 are reserved as well. For more information on reserved
port numbers, see to Table 7-5. Reserved Port Numbers on page 42.
XPort Direct+ User Guide 11
Configuration Methods
For the unit to operate correctly on a network, it must have a unique IP address on
the network. There are three basic methods for logging into the device server to
assign an IP address and configure the unit:
DeviceInstaller: Assign an IP address and view the current XPort Direct+
configuration using a Graphical User Interface (GUI) on a PC attached to a network.
(See 3: Using DeviceInstaller.)
Web-Manager: Through a web interface, configure the XPort Direct+ and its settings
using the XPort Direct+ Web-Manager. (See 4: Configuration Using Web Manager.)
Serial & Telnet Ports: There are two approaches to accessing Serial Mode. Make a
Telnet connection to the network port (9999) or connect a terminal (or a PC running a
terminal emulation program) to the unit’s serial port. (See 5: Configuration via Telnet
or Serial Port (Setup Mode) )

5: Configuration via Telnet or Serial Port
(Setup Mode)
You must configure the unit so that it can communicate on a network with your serial
device. As an alternative to using a web browser, as described in the previous
chapter, you can use the following procedures remotely or locally:
Use a Telnet connection to configure the unit over the network.
Use a terminal or terminal emulation program to access the serial port
locally.
The series of prompts at which you enter configuration settings is called Setup
Mode.
Note: Detailed information about other setup methods is available from your
Lantronix Sales Associate.
The unit’s configuration is stored in nonvolatile memory and is retained without
power. You can change the configuration at any time. The unit performs a reset after
the configuration has been changed and stored.
This chapter tells you how to access Setup Mode and the general procedure for
using it. To complete the configuration, continue with 6: Setup Mode: Server
Configuration, 7:Setup Mode: Channel Configuration, and 8:Setup Mode: Advanced
Settings.
Note: The menus in the configuration chapters show a typical device. Your
device may have different configuration options.

stop bit, no-flow control.
Note: The XPort Direct+ always uses the serial settings above at boot
time.
2. Connect a console terminal or PC running a terminal emulation program to your
unit's serial port. The default serial port settings are 9600 baud, 8 bits, no
parity, 1-stop bit, no-flow control.
XPort Direct+ User Guide 35
3. Reset the XPort Direct+ unit by cycling the unit's power (turning the power off
and back on). Immediately upon resetting the device, enter three lowercase x
characters (xxx).
Note: The easiest way to enter Setup Mode is to hold down the x key at
the terminal (or emulation) while resetting the unit. You must do this
within three seconds of resetting the XPort Direct+.
At this point, the screen display is the same as when you use a Telnet connection. To
continue, go to step 4 in Telnet Connection, above.

address must be set to a unique value in the network. Enter each octet and press
Enter between each section. The current value displays in parentheses.
If DHCP is used, the third octet of the IP address sets the BootP/DHCP/AutoIP
options. The following table shows the bits you can manually configure to force the
XPort Direct+ to disable AutoIP, DHCP, or BootP. To disable an option, set the
appropriate bit.
For example, if the third octet is 0.0.5.0, the AutoIP and BootP options are disabled;
only DHCP is enabled. (The value 5 results from adding the binary equivalents of 0
and 2.) This is the most common setting when using DHCP.

DHCP Name
If a DHCP server has automatically assigned the IP address and network settings,
you can discover the unit by using the DeviceInstaller network search feature.
There are three methods for assigning DHCP names to the unit.
XPort Direct+ User Guide 38
6: Setup Mode: Server Configuration
Default DHCP Name: If you do not change the DHCP name, and you are
using an IP of 0.0.0.0, then the DHCP name defaults to CXXXXXX (XXXXXX
is the last 6 digits of the MAC address shown on the label on the bottom/side
of the unit). For example, if the MAC address is 00-20-4A-12-34-56, then the
default DHCP name is C123456.
Custom DHCP Name: You can create your own DHCP name. If you are
using an IP address of 0.0.0.0, then the last option in Server configuration is
Change DHCP device name. This option allows you to change the DHCP
name to an alphanumeric name (LTX in our example).
Change DHCP device name (not set) ? (N) Y
Enter new DHCP device name : LTX
Numeric DHCP Name: You can change the DHCP name by specifying the
last octet of the IP address. When you use this method, the DHCP name is
LTXYY where YY is what you chose for the last octet of the IP address. If the
IP address you specify is 0.0.0.12, then the DHCP name is LTX12. This
method only works with 2 digit numbers (01-99).

XPort Direct+ User Guide 44
7: Setup Mode: Channel Configuration
Manual Connection
Attempts to connect when directed by a command string
received from the serial port. The first character of the command
string must be a C (ASCII 0x43), and the last character must be
either a carriage return (ASCII 0x0D) or a line feed (0x0A). No
blanks or space characters may be in the command string.
Between the first and last command string characters must be a
full or partial destination IP address and may be a destination
port number.
The IP address must be in standard decimal-dot notation and
may be a partial address, representing the least significant 1, 2,
or 3 bytes of the remote IP address. The period is required
between each pair of IP address numbers.
If present, the port number must follow the IP address, must be
presented as a decimal number in the range 1-65535, and must
be preceded by a forward slash (ASCII 0x2F). The slash
separates the IP address and the port number. If you omit the
port number from a command string, the internally stored remote
port number starts a connection.
If a partial IP address is presented in a command string, it is
interpreted to be the least significant bytes of the IP address and
uses the internally stored remote IP address to provide the most
significant bytes of the IP address. If the IP address entered is
0.0.0.0/0, the device server enters Monitor Mode.
For example, if the remote IP address already configured in the
unit is 129.1.2.3, then an example command string would be
C3/7. (This would connect to 129.1.2.3 and port 7.) You may
also use a different ending for the connection string. For
example, C50.1/23 would connect you to 129.1.50.1 and port 23.

If you enable Autostart, the unit automatically connects to the
remote IP address and remote port specified when the firmware
starts.
If you enable this option, the device server scrolls through the
hostlist until it connects to a device listed in the hostlist table.
Once it connects, the unit stops trying to connect to any others. If
this connection fails, the unit continues to scroll through the table
until it is able to connect to another IP in the hostlist.
Hostlist supports a minimum of 1 and a maximum of 12 entries.
Each entry contains the IP address and the port number.
The hostlist is disabled for Manual and Modem Modes. The unit
does not accept a data connection from a remote device when
the hostlist option is enabled.
XPort Direct+ User Guide 45
7: Setup Mode: Channel Configuration
Figure 4-7. Hostlist Option
To enable the hostlist:
1. Enter a Connect Mode of 0x20 (2X), where X is any digit. The menu shows you
a list of current entries already defined in the product.
2. To delete, modify, or add an entry, select Yes. If you enter an IP address of
0.0.0.0, that entry and all others after it are deleted.
3. After completing the hostlist, repeat the previous step if necessary to edit the
hostlist again.
4. For Retrycounter, enter the number of times the Lantronix unit should try to
make a good network connection to a hostlist entry that it has successfully
ARPed. The range is 1-15, with the default set to 3.
5. For Retrytimeout, enter the number of seconds the unit should wait before
failing an attempted connection. The time is stored as units of milliseconds in the
range of 1-65535. The default is 250.
XPort Direct+ User Guide 46
d) Datagram Type
7: Setup Mode: Channel Configuration
Directed UDP
When selecting this option, you are prompted for the Datagram type.
Enter 01 for directed or broadcast UDP. Datagrams of type 01 can be
sent as a broadcast by enabling the Send as Broadcast option. The
default is not to broadcast.
When the UDP option is in effect, the unit never attempts to initiate a
TCP connection because it uses UDP datagrams to send and receive
data.
e) Modem Mode
In Modem (Emulation) Mode, the unit presents a modem interface to the attached
serial device. It accepts AT-style modem commands and handles the modem signals
correctly.
Normally, there is a modem connected to a local PC and a modem connected to a
remote machine. A user must dial from the local PC to the remote machine,
accumulating phone charges for each connection. Modem Mode allows you to
replace modems with XPort Direct+ units, and to use an Ethernet connection instead
of a phone call. By not having to change communications applications, you avoid
potentially expensive phone calls.
To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full
verbose), D7 (echo with numeric response), CF (modem responses only, numeric
response), or CE (modem responses only, full verbose).
Note: If the unit is in Modem Mode, and the serial port is idle, the unit can
still accept network TCP connections to the serial port if Connect Mode is set
to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric
response, CF (modem responses only, numeric response), or CE (modem
responses only, full verbose).
Without Echo
Data Echo & Modem

In Modem Mode, echo refers to the echo of all of the characters
entered in command mode; it does not mean to echo data that is
transferred. Quiet Mode (without echo) refers to the modem not
sending an answer to the commands received (or displaying what
was typed).
Full Verbose: The unit echoes modem commands and responds to
a command with a message string shown in the table below.
Numeric Response: The unit echoes modem commands and
responds to a command with a numeric response.
Full Verbose: The unit does not echo modem commands and
responds to a command with a message string shown in the table
below.
Numeric Response: The unit does not echo modem commands
and responds to a command with a numeric response.

Received commands must begin with the two-character sequence AT and be
terminated with a carriage return character.
The unit ignores any character sequence received not starting with AT, and only
recognizes and processes single AT-style commands. The unit treats compound AT
commands as unrecognized commands.
If the Full Verbose option is in effect, the unit responds to an unrecognized
command string that is otherwise formatted correctly (begins with AT and ends with
carriage return) with the "OK" message and takes no further action.
If the Numeric Response option is in effect, the unit responds to an unrecognized
command string that is otherwise formatted correctly with the "OK" message and
takes no further action.
When an active connection is in effect, the unit transfers data and does not process
commands received from the serial interface.
When a connection is terminated or lost, the unit reverts to command mode.
When an active connection is in effect, the unit terminates the connection if it
receives the following sequence from the attached serial device:
No serial data is received for one second.
The character sequence +++ is received, with no more than one second
between each two characters.
No serial data is received for one second after the last + character. At this
time, the unit responds affirmatively per the selected echo/response mode.
The character string ATH is received, terminated with a carriage return. The
unit responds affirmatively according to the selected echo/response mode
and drops the network connection. The serial interface reverts to accepting
command strings.
If this sequence is not followed, the unit remains in data transfer mode.

Alternate Packing Algorithm (Pack Control)
Enable 1
XPort Direct+ User Guide 51
Pack Control
The packing algorithms define how and when packets are sent to the network. The
standard algorithm is optimized for applications in which the unit is used in a local
environment, allowing for very small delays for single characters, while keeping the
packet count low. The alternate packing algorithm minimizes the packet count on the
network and is especially useful in applications in a routed Wide Area Network
(WAN). Adjusting parameters in this mode can economize the network data stream.
Pack control settings are enabled in Flush Mode. Set this value to 00 if you do not
need specific functions.
Note: All bit positions in the table that are blank represent “don’t care” bits,
for that particular option, which can be set to either a 0 or 1 value.

Packing Interval
Packing Interval defines how long the unit should wait before sending accumulated
characters. This wait period is between successive network segments containing
data. For alternate packing, the default interval is 12 ms.
Trailing Characters
In some applications, CRC, Checksum, or other trailing characters follow the end-ofsequence character; this option helps to adapt frame transmission to the frame
boundary.
XPort Direct+ User Guide 52
Send Characters
If 2-Byte Send Character Sequence is enabled, the unit interprets the
sendchars as a 2-byte sequence; if this option is not enabled, the unit
interprets them independently.
If Send Immediately After Characters is not set, any characters already in
the serial buffer are included in the transmission after a "transmit" condition is
found. If this option is set, the unit sends immediately after recognizing the
transmit condition (sendchar or timeout).
Note: A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
DisConnTime (Inactivity Timeout)
Use this parameter to set an inactivity timeout. The unit drops the connection if there
is no activity on the serial line before the set time expires. Enter time in the format
mm:ss, where m is the number of minutes and s is the number of seconds.
DisConnTime (0: 0) ?:
To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds
(99 minutes, 59 seconds). Default is 0.
7: Setup Mode: Channel Configuration
Send Characters
Enter up to two characters in hexadecimal representation in sendchar.
SendChar 1 ( 0) ? _
SendChar 2 ( 0) ? _
If the unit receives a character on the serial line that matches one of these
characters, it sends the character immediately, along with any awaiting characters, to
the TCP connection. This action minimizes the response time for specific protocol
characters on the serial line (for example, ETX, EOT). Setting the first sendchar to 00
disables the recognition of the characters. Alternatively, the unit can interpret two
characters as a sequence (see Pack Control on page 52).
Telnet Terminal Type
This parameter displays only if you enabled the terminal type option in Disconnect
Mode. With this option enabled, you can use the terminal name for the Telnet
terminal type. Enter only one name.
With terminal type option enabled, the unit also reacts to the EOR (end of record) and
binary options, useful for applications like terminal emulation to IBM hosts.
Channel (Port) Password
This parameter appears only if the channel (port) password option is enabled in
Disconnect Mode. With this option enabled, you can set a password on the serial
port.

CPU Performance
XPort Direct+ User Guide 57
8: Setup Mode: Advanced Settings
This option applies to XPort Direct+ and later units only. It allows you to increase the
CPU performance required to use the higher baud rates on the serial interface (460
Kbps and 920 Kbps). The standard CPU performance mode supports up to 230400
Kbps.
Notes:
If a baud rate of 460 Kbps or 920 Kbps is set and the high performance mode is
disabled, the operation of the serial channel would be out of the specified error
tolerance, thereby leading to inconsistent speed settings on the two ends of the
serial channel.
Increasing CPU clock speed consumes more power and generates more heat.
This reduces the maximum operating temperature specification. See the
appropriate product brief for details.
Disable Monitor Mode at bootup
This option allows you to disable all entries into Monitor Mode during startup, except
for the ‘xxx’ sequence. This prevents entry using yyy, zzz, xx1, and yy1 key

9: GPIO Interface
Configurable Pins
The XPort Direct+ has three pins (CP0-2) that you can configure for General Purpose
I/O (GPIO).
Note: You can also configure any one of the pins for modem control input
signal (serial port control line) using DeviceInstaller.
You can use these GPIO pins to control devices such as relays, servers, lights,
monitor switches, sensors, and even processes such as data transfer.
You can set the functions for the three pins independently and in any combination.
The initial directions (input/output) and active levels (active low or high) at boot up
can also be configured through 77FE, for example, by using DeviceInstaller.
This chapter describes how the directions, active levels, and states can be
dynamically controlled and probed through special port 77F0.
The configurable pins default configuration is:
Function: General Purpose Input
Active Level: Active Low
Features
TCP and UDP can be used.
Function configuration can be retrieved.
Input or output selection can be retrieved and controlled.
Active low or high selection can be retrieved and controlled.
Active or inactive selection can be retrieved and controlled.
77F0 can be disabled.
Every change of state (active/inactive) requires a command over TCP or UDP, and
thus is not very fast. If you use this port for data transfer, the throughput is low,
usually up to 1 Kbps.
XPort Direct+ User Guide 64
9: GPIO Interface
Control Protocol
COPIED FROM XPORT DIRECT.
The GPIO control protocol is a simple, proprietary protocol.
Guidelines
The GPIO control protocol is described from the PC side. Send means from PC to
XPort Direct+. Response comes from XPort Direct+ to PC.
The protocol allows for control of up to 32 GPIOs. How many are actually available
depends on the product. XPort Direct+ has only two.
The parameters are four bytes long and represent GPIOs 0-31, with GPIO0 in bit 0 of
the first byte (Little Endian). Parameter bits for configurable pins not configured as
GPIOs are undefined for Get commands and ignored on Set commands.
Every command consists of nine bytes: one command type of one byte and two
parameters of four bytes each.
Command Parameter 1 Parameter 2
0 1 2 3 4 5 6 7 8
On some commands, one or all parameters are ignored.
For UDP, command type and parameters need to be in the same datagram.
Responses to valid commands are always five bytes long, consisting of the returned
command byte and as parameters in the current or updated values. In case of an
invalid command, only one byte with value 0FFh is returned.
Command Parameter 1
0 1 2 3 4
When sending a command (TCP and UDP), wait for the response before sending the
next command.
Commands
Byte 0 Command Types
10h Get functions
11h Get directions (input or output)
12h Get active levels (high active or low active)
13h Get current states (active or not active)
19h Set directions
1Ah Set active levels
1Bh Set current states
There is no Set functions command. Since the pin’s function depends on the
hardware in which the XPort Direct+ is embedded, that configuration is only allowed
using 77FE. Settings changed by any of the Set commands are not stored and are
lost when the unit is powered down or rebooted.

12: Troubleshooting
This chapter discusses how you can diagnose and fix errors quickly without having to
contact a dealer or Lantronix. It helps to connect a terminal to the serial port while
diagnosing an error to view summary messages that may display. When
troubleshooting, always ensure that the physical connections (power cable, network
cable, and serial cable) are secure.
Note: Some unexplained errors might be caused by duplicate IP addresses on the
network. Make sure that your unit's IP address is unique.
When troubleshooting the following problems, make sure that the XPort Direct+ is
powered up. Confirm that you are using a good network connection.
Problems and Error Messages
Problem/Message Reason Solution
When you issue the ARP –S
command in Windows, the "ARP
entry addition failed: 5" message
displays.
When you attempt to assign an
IP address to the unit by the
ARP method, the "Press Enter to
go into Setup Mode" error
"(described below) message
displays. Now when you Telnet
to the device server, the
connection fails.
When you Telnet to port 9999,
the "Press Enter to go into Setup
Mode" message displays.
However, nothing happens when
you press Enter, or your
connection is closed.
Your currently logged-in
user does not have the
correct rights to use this
command on this PC.
When you Telnet to port
1 on the device server,
you are only assigning a
temporary IP address.
When you Telnet into
port 9999 and do not
press Enter quickly, the
device server reboots,
causing it to lose the IP
address.
You did not press Enter
quickly enough. You
only have 5 seconds to
press Enter before the
connection is closed.
Have someone from your IT
department log you in with
sufficient rights.
Telnet back to Port 1. Wait for
it to fail, then Telnet to port
9999 again. Make sure you
press Enter quickly.
Telnet to port 9999 again, but
press Enter as soon as you
see the "Press Enter to go into
Setup Mode" message.
XPort Direct+ User Guide 75
Problem/Message Reason Solution
When you Telnet to port 1 to
assign an IP address to the
device server, the Telnet window
does not respond for a long time.
When you try to assign an IP
with DeviceInstaller, you get the
following :
"No response from device!
Verify the IP, Hardware
Address and Network Class.
Please try again."
The device server is not
communicating with the serial
device to which it is attached.
When you try to enter the setup
mode on the device server using
the serial port, you get no
response.
You may have entered
the Ethernet address
incorrectly with the ARP
command.
The IP address you are
trying to assign is not on
your logical subnet.
The device server may
not be plugged into the
network properly.
The cause is most likely
one of the following:
The hardware address
you specified is
incorrect.
The IP address you are
trying to assign is not a
valid IP for your logical
subnet.
You did not choose the
correct subnet mask.
The most likely reason is
the wrong serial settings
were chosen.
The issue is most likely
something covered in
the previous problem, or
possibly, you have Caps
Lock on.
Confirm that the Ethernet
address that you entered with
the ARP command is correct.
The Ethernet address may
only include numbers 0-9 and
letters A-F. In Windows and
usually in Unix, the segments
of the Ethernet address are
separated by dashes. In some
forms of Unix, the Ethernet
address is segmented with
colons.
Confirm that your PC has an
IP address and that it is in the
same logical subnet that you
are trying to assign to the
device server.
Make sure that the Link LED is
lit. If the Link LED is not lit,
then the device server is not
properly plugged into the
network.
Double-check the parameters
that you specified.
Note: You cannot assign an
IP address to a device server
through a router.
The serial settings for the
serial device and the device
server must match. The
default serial settings for the
device server are RS-232,
9600 baud, 8 character bits,
no parity, 1 stop bit, no flow
control.
Double-check everything in
the problem above. Confirm
that Caps Lock is not on.
Troubleshooting
XPort Direct+ User Guide 76
Problem/Message Reason Solution
You can ping the device server,
but not Telnet to the device
server on port 9999.
The device server appears to be
set up correctly, but you are not
communicating with your device
attached to the device server
across the network.
When connecting to the WebManager within the device
server, the "No Connection With
The Device Server" message
displays.
There may be an IP
address conflict on your
network
You are not Telneting to
port 9999.
The Telnet configuration
port (9999) is disabled
within the device server
security settings.
If you are sure that the
serial port setting is
correct, then you may
not be connecting to the
correct socket of the
device server.
Another possibility is that
the device server is not
set up correctly to make
a good socket
connection to the
network.
Your computer is not
able to connect to port
30718 (77FEh) on the
device server.
Turn the device server off and
then issue the following
commands at the DOS prompt
of your computer:
ARP -D X.X.X.X (X.X.X.X is
the IP of the device server).
PING X.X.X.X (X.X.X.X is the
IP of the device server).
If you get a response, then
there is a duplicate IP address
on the network. If you do not
get a response, use the serial
port to verify that Telnet is not
disabled.
You can check to see whether
there is a socket connection to
or from the device server by
checking the state of CP1, if it
has been configured for LED1
functionality.
If the state of CP1 is blinking
consistently, or is completely
off, then there is a good
socket connection.
If the state of CP1 is low, use
the Connect Mode option C0
for making a connection to the
device server from the
network. Use Connect Mode
option C1 or C5 for a
connection to the network
from the device server. See
the full list of Connect Mode
options in Connect Mode on
page 43.
Make sure that port 30718
(77FEh) is not blocked with
any router that you are using
on the network. Also, make
sure that port 77FEh is not
disabled within the Security
settings of the device server.

A: Binary to Hexadecimal
Conversions
Many of the unit’s configuration procedures require assembling a series of options
(represented as bits) into a complete command (represented as a byte). Convert the
resulting binary value to a hexadecimal representation.
Converting Binary to Hexadecimal
Following are two simple ways to convert binary numbers to hexadecimals.
Conversion Table
Hexadecimal digits have values ranging from 0 to F, which are represented as 0-9, A
(for 10), B (for 11), etc. To convert a binary value (for example, 0100 1100) to a
hexadecimal representation, the upper and lower four bits are treated separately,
resulting in a two-digit hexadecimal number (in this case, 4C). Use the following table
to convert values from binary to hexadecimal.
Decimal Binary Hex
0 0000 0
1 0001 1
2 0010 2
3 0011 3
4 0100 4
5 0101 5
6 0110 6
7 0111 7
8 1000 8
9 1001 9
10 1010 A
11 1011 B
12 1100 C
13 1101 D
14 1110 E
15 1111 F
Scientific Calculator
Another simple way to convert binary to hexadecimals is to use a scientific calculator,
such as the one available on Windows’ operating systems. For example:
1. On the Windows’ Start menu, click ProgramsÆAccessoriesÆCalculator.
2. On the View menu, select Scientific. The scientific calculator displays.
