1. Overview
Wi232 is a wireless embedded device server that provides serial-to-wireless network connectivity. Wi232
allows virtually any RS232 serial device or equipment to be remotely accessed, controlled, monitored or
shared on an 802.11b wireless network.
The Wi232 functions independently of a PC, providing a fully integrated solution that combines a processor,
memory, 802.11b transceiver, Ethernet port, and a high-speed serial port into a single compact module. It
includes an operating system, an embedded Web server, full TCP/IP protocol stack and WEP/WPA security.
In addition, the Wi232 supports numerous other network communication protocols, including ARP, UDP,
TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP.
For designers who wish to customize the user interface by employing common and familiar tools, the Wi232
serves applets to a Web browser, resulting in interactive Web pages. This customization of HTML Web
pages and configuration screens tailors the Wi232 to fit unique requirements.
The Wi232 device server has the following capabilities:
• Communication between TCP and UDP to serial.
• Wireless interface (802.11b or Ethernet interface.
• Upgradeable firmware.
• SNMP monitoring.
• Connects devices through a TCP or UDP data channel to computers or to another de vice server.
• Contains a web server allowing presentation of custom content and easy configuration through the
browser.
Some of the devices are:
• ATM Machines
• CNC Controllers
• Data Collection Devices
• Universal Power Supply (UPS) Management Units

1.2 Application Examples
The Wi232 has a serial port, an Ethernet port and an 802.11b transceiver. You can enable either the Ethernet
port or the Wireless LAN. The serial port connects to the serial communication port of your device. The
wireless transceiver connects to another wireless device or to an Access Point (AP) connecting to a network
through an Ethernet link.
This section includes four typical scenarios for using the Wi232.
Figure 1 - Serial Tunneling Example
Ethernet
Personal Computer (PC)
Wireless Laptop Wi232
POS Device
A PC connected to an Access Point via an Ethernet connection and a laptop with a wireless connection to
the Access Point LAN access the Wi232 as though they are directly connected to it. The combination of the
Wi232, a PC, and Redirector software allows the PC to directly communicate to the Wi232’s serial devices,
providing wireless serial tunneling.
Figure 2 - Ad-Hoc Network Example
Wireless Laptop
POS Devi ce
Wi232
In the above example, the Access Point is not present. The laptop makes a direct wireless connection with
the Wi232 to manage serial devices. Without an AP, it is a peer-to peer relationship.

In the above example, the Wi232 communicates with another device server via the Access Point. The
NET232 device server, in this example, is connected via an Ethernet connection to the Access Point. As
such, the Wi232 and the device server communicate directly and can transfer information between their
serial devices. This configuration is called Infrastructure mode.

In the above example, two Wi232s have established an Ad-Hoc peer-to-peer relationship. They
communicate directly to each other’s serial devices without a PC or an Access Point.
Note: How do you set up the units for point-to-point? See Application Note, Wi232 Serial Tunnel, GC-800-302.
1.3 Protocol Support
The Wi232 uses the Internet Protocol (IP) for network communications and 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.
Other 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.

2. Quick Start
This section describes a procedure for quickly installing the Wi232 through the serial port.
2.1 Required Information
2.1.1 Hardware Address
You need to know the unit's hardware address (also known as MAC address), which is on the manufacturers
ID label on the bottom of the unit. It is in the format: 00-20-4a-XX-XX-XX, where the XXs are unique
numbers assigned to the product.
Hardware Address: 00-20-4a- ____ - ____ - ____
2.1.2 WLAN Settings
Your Wi232 must have a unique IP address on your network. The systems administrator generally provides
the IP address and corresponding subnet mask and gateway. If you leave the IP address set to 0.0.0.0, the
Wi232 will attempt to get a DHCP address from the wireless Access Point or network server. If it cannot get
a DHCP address, it will use AutoIP to assign an IP address.
Before the Wi232 can communicate on an 802.11b wireless network, the WLAN settings must match the
wireless network. By default, the Wi232 is set to Infrastructure network mode and its wireless Network
Name (SSID) is LTRX_IBSS. You will need to change the Network Name (SSID) to the name used by
your wireless Router or Access Point.
IP Address: _____ _____ _____ _____
Subnet Mask: _____ _____ _____ _____

3.5 Email Configuration
The Wi232 uses a standard WiPort Wireless Serial to Ethernet module. It includes many functions for an
OEM developer including e-mail options and configurable pins. The Wi232 does not utilize any
configurable pins. Therefore, you cannot setup email using configurable pins for triggers. Ignore any web,
telnet, or serial port references to these items.
You can enable the e-mail option ONLY with a serial trigger input. This requires two bytes of data to trigger
the email. It also means that every time the same two bytes appear, you get another e-mail message. You
can set some parameters to try and prevent multiple messages. You should only use this if you really need email message triggering with a two-byte data pattern. The Wi232 was not designed to be a wireless e-mail
trigger device.
3.6 WLAN Configuration
Without adequate protection, a wireless LAN is susceptible to access by unauthorized users. As such,
Wi232 includes the Wired Equivalent Privacy (64/128-bit WEP) encryption standard, Wi-Fi Protected
Access (WPA-PSK), TKIP Encryption, and 802.11i/WPA2 as a means of security.
The Wi232 WLAN Settings menu permits the following actions:
• Configuration of the wireless network profile available for activation.
• Configuration of the wireless network security settings.
• Configuration of advanced settings such as radio power management.
For connecting to wireless networks, the configuration of a name for the network with which the Wi232 wants to
associate is done with the Network Name (SSID) field. The Wi232 then searches for the configured
network among the available wireless networks in both the Infrastructure (Access Point) and Ad Hoc
modes.
In the case that there is no network with the configured name within the range of the Wi232, there is an
option to create an Ad Hoc network allowing other devices to associate with the Wi232 using the configured
Wireless Network Configuration field parameters. You can also disable the WLAN and select a wired
Ethernet connection.
3.6.1 WLAN Country Setting
The Country setting has been removed from the WLAN setup options starting in firmware version 6.0.0.0.
The default setting is United States. To change the setting, use the SetZone utility. See the user document in
the SetZone Utility folder on the CD. The syntax is:
SetZone <IP address> [<zone abbreviation>]
Leaving the zone abbreviation blank causes the utility to report the current setting only. Valid zone
abbreviations are US, FR, JP and OT.

Ethernet network. Infrastructure mode wirele ss also supports central connectio n points for
WLAN clients.
A wireless access point (AP) is required for infrastructure mode w ireless netwo rking. To
join the WLAN, the AP and all wireless clients must be configured to use the same SSID.
The AP is then cabled to the wired network to allow wireless clients a ccess to , for
example, Internet connections or printers. Additional APs can be added to the WLAN to
increase the reach of the infrastructure and support any number of wireless clie nts.
Ad Hoc mode - An 802.11 networking framework in which devices or stations
communicate directly with each other, without the use of an access poin t (AP). Ad-hoc
mode is also referred to as peer-to-peer mode or an Independent Basic Service Set
(IBSS). Ad-hoc mode is useful for establishing a network where wireless infrastructure
does not exist or where services are not required.
Select from the pull down menu the radio channel for the Ad
Hoc network. The default value is 11.
Wireless Network Security
Security
The Wi232 can use different security options.
The Wired Equivalent Privacy (WEP) algorithm is used to protect wireless
communication from eavesdropping. A secondary function of WEP is to prevent
unauthorized access to a wireless network; this function is not an explicit goal in the
802.11 standard, but it is frequently considered to be a feature of WEP. WEP relies on a
Wi232/WiUSB User Guide 3-13
secret key that is shared between a mobile station (eg. a laptop with a w ireless ethernet
card) and an access point (ie. a base station). The secret key is used to encrypt packe ts
before they are transmitted, and an integrity check is used to ensure that packets are not
modified in transit.
Wi-Fi Protected Access (WPA) is a system to secure wireless (Wi-Fi) netw orks, created
to patch the security of the previous syst em, WEP (Wired Equivalent Privacy ). WPA is
designed for use with an 802.1X authentication server, which distributes different keys
to each user; however, it can also be used in a less secure pre-shared key (PSK) mode.
By default, security is disabled on Wi232.
802.11i/WPA2 is an amendment to the 802.11standard specifying security mechanisms
for wireless networks. 802.11i is the latest standard for 802 .11-based wireless LAN
security. WPA2 is the Wi-Fi Alliance certification program, based on the support by
equipment and software for what it considers to be mandatory features of 802.11i.
The features in IEEE 802.11i and WPA2 are virtually identical. The two most i mportant
features beyond WPA to become standardized through 802.11i/WPA2 are: preauthentication, which enables secure fast roaming without noticeable signal latency; and
the use of the CCMP cipher suite in place of TKIP. CCMP is based on the AES cipher.
AES yields the high level of data privacy required by some enterprises, government
agencies and other organizations. CCMP support is mandatory in both the 802.11i
specification and WPA2. Pre-authentication will be optional for both 802.11i and WPA2.

4. Configuration via Serial Mode or Telnet
Port
The Wi232 unit is configurable using a terminal program to access the serial port locally. When power is
applied, the unit goes into boot mode and ALWAYS communicates with the serial port the same way. You can’t change
the settings for the boot sequence but after a few seconds, the unit reverts to the saved settings. The unit’s configuration
is stored in nonvolatile memory and is retained even without power. Using a terminal program to respond to
prompts is referred to as the Serial Mode.
Yo u m u st c o nf i g u r e t h e W i 2 3 2 s e r i a l po r t s o th a t i t c a n c o mm u n i c at e on a network with your serial devices. You
can change the configuration at any time. The unit performs a reset after the configuration has been changed
and stored.
Note: The menus in this section show a typical device. Not all devices display information in the same
manner.
To configure the unit through a serial connection:
1. Connect a console terminal or PC runnin g a t er mi n a l em ulation program to your u n i t' s s e r i a l po r t . F or 5 s e c on d s

Change DHCP Device Name
This option appears if the IP address is set to 0.0.0.0.
There are three methods for assigning DHCP names to the unit.
• Default DHCP Name: If the DHCP name is not changed and the IP is 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: Create your own DHCP name. If 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 the example).
Change DHCP device name (not set)
Enter new DHCP device name : LTX
• Numeric DHCP Name: Ch a n g e t h e D H CP n a m e b y s p e c i fy i n g th e l a s t o c t e t of the IP address. When
using this method, the DHCP name is LTXYY where YY is the last octet of the IP address. If the
IP address specified is 0.0.0.12, then the DHCP name is LTX12. This method only works with 2 digit
numbers (0-99).

4.2.4 Port Number
The Port No setting represents the source port number in TCP connections. It is the number that identifies
the channel for remote initiating connections. The port number functions as the TCP/UDP source port
number for outgoing packets. Packets sent to the unit with this port number are received to this channel. The
port number selected is the Incoming TCP/UDP port and Outgoing TCP/UDP source port.
Port No (10001) ? _
The current value is displayed in parentheses. The default setting for Port 1 is 10001. The range is 1-65535,
except for the following reserved port numbers:
Port Numbers Reserved for
1 – 1024 Reserved
9999 Telnet setup
14000-14009 Reserved for Redirector
30718 Reserved (77FEh)
Note: Do NOT use the reserved port numbers for this setting as incorrect operation may result.
Use Port 1 for the outgoing local port to change with each connection. The port range is 50,000 to 59,999. Each
subsequent connection increments the number by 1 (it wraps back around to 50,000).
Only use this automatic port increment feature to initiate a connection using TCP. Set the port to a non-zero
value when the unit is in a passive mode or when using UDP instead of TCP.

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 destin ation IP address and
can include a destination port number.
The IP address must be in standard dot-decimal 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 octet 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 a nd uses
the internally stored remote IP address to provide the most sig nificant
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 C23/7. (This
would connect to 129.1.23 and port 7.) You may also use a different
ending for the connection string. For example, C50.1/23 would connec
you to 129.1.50.1 and port 23.

The hostlist operates in a sequential order when attempting to connect
to the first available host. If this option is set to True, the device server
scrolls through the hostlist until it connects to the first available device
listed in the hostlist table. Once it connects, the unit stops further
attempts. If this connection fails, the unit continues to scroll through the
table until it is able to connect to the next available IP address 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 Mode and for Modem Mode. The unit will not
accept a data connection from a remote device when the hostlist
option is enabled.
4-8 Wi232/WiUSB User Guide
To enable the hostlist:
1. Enter a Connect Mode of 0x20 (2x). The menu shows a list of current entries already defined.
2. To delete, modify, or add an entry, select Yes. If entering an IP address of 0.0.0.0, that entry and all
others after it are deleted.

Datagram Type
Directed UDP
When selecting this option, the prompt requests the Datagram type.
Enter 01 for directed or broadcast UDP.
When the UDP option is in effect, the unit uses UDP datagrams to
send and receive data.
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 m odem connecte d to a rem ote machine. A user must
dial f rom t h e loc a l P C t o the r emot e mach i n e, accumulating phone charges for each connection. Mod e m Mod e
allows you to replace modems with Wi232es, and to use an Ethernet connection instead of a phone call. By not
having to change communic ations applications, you avoid potentially expensive phone calls.
To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), or D7 (echo with 1character response).
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), or D7 (echo with 1-character
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 1-Character Response option is in effect, the unit responds to an unrecognized command string that is
otherwise formatted correctly with
OK 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.

Pack Control
The packing algorithm defines how and when packets are sent to the network. The standard algorithm is
op t i m i z e d f o r ap p l i c a t i o n s i n w h ich t h e u n i t i s us e d in a local environment. 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 specific functions are not needed.

Packing Interval: Pa c k i n g I n ter v a l d e f i n es h o w l o n g t he u n i t s h o u l d 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 som e app lica tio ns, CRC, Che cks um, o r ot her trai lin g characters follow the end-of-sequence
character; this option helps to adapt frame transmission to the frame boundary.
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 inform ation needs to be exchanged or an acknowledgment needs to be sent.
4.2.12 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). The default is 0.

4.2.13 SendChar 1 and SendChar2
Enter up to two characters in hexadecimal representation.
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 47).
4.2.14 Telnet Terminal Type
This parameter displays only if the terminal type option is enabled in Disconnect Mode. If this option is
enabled, use the terminal name for the Telnet terminal type. Enter only one name.
If the terminal type option is enabled, the unit also reacts to the EOR (end of record) and binary options,
which can be used for applications such as terminal emulation to UNIX hosts.
4.2.15 Channel (Port) Password
This parameter appears only if the channel (port) password option is enabled in Disconnect Mode. If the
option is enabled, set a password on the serial port.
4.3 E-mail
The Wi232 does not utilize this feature at this time. You can make it work by looking for characters on the
serial port. However, we do not recommend this operation.
4.4 WLAN Settings
A wireless LAN is susceptible to access by unauthorized users. As such, Wi232 includes the Wired
Equivalent Privacy (WEP) encryption standard, Wi-Fi Protected Access (WPA), and 802.11i/WPA2 as a
means of security.
The Wi232 WLAN Settings menu permits the following actions:
• Configuration of the wireless network profile available for activation.
• Configuration of the wireless network security settings.
• Configuration of advanced settings such as radio power management.
For connecting to wireless networks, the configuration of a name (SSID) for the network with which the
Wi232 wants to associate is done with the Network Name (SSID) field. The Wi232 then searches for the
configured network among the available wireless networks in both the Infrastructure (Access Point) and Ad
Hoc modes.
In the case that there is no network with the configured name within the range of the Wi232, there is an
option to create an Ad Hoc network allowing other devices to associate with the Wi232 using the configured
Enable Ad Hoc network creation field parameters.
To modify WLAN and security settings, select 4 WLAN from the Change Setup menu.

4.5 Expert Settings
Note: Change these settings via Telnet or serial connections only.
Caution: Only an expert should change these parameters. These changes hold serious consequences.
TCP Keepalive Time
TCP Keepalive time defines how many seconds the unit waits during a silent connection before checking
whether the currently connected network device is still on the network. If the unit does not receive a response,
it drops that connection.
TCP Keepalive time in s (1s – 65s; 0s=disable): (45)? _
ARP Cache Timeout
When the unit communicates with another device on the network, it adds an entry into its ARP table. ARP
Cache timeout defines the number of seconds (1-600) the unit waits before timing out this table.
ARP Cache timeout in s (1s- 600s; 0s=disable): (600)?
CPU Performance
The standard CPU performance mode supports up to 230400 baud. Select 1=Low for low power. Select
2=High to increase the CPU performance and utilize the higher baud rates on the serial interface (i.e.
460Kbps and 920Kbps). Increasing CPU performance requires more power and lowers the unit’s operating
temperature.
CPU performance (0=Regular, 1=Low, 2=High): 0
Note: If baud rates of 460Kbps or 920Kbps is set and the high performance mode 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.
Disable Monitor Mode
Disables entry into Monitor Mode via the 'yyy' or 'xx1' key sequence at startup. This command prevents the

ARP method and Telnet to the
device server through port 1, the
connection fails.
The ARP method only creates a
temporary password. When you
Telnet to port 1, the connection
should fail. When you Telnet into
port 9999 and do not press Enter
quickly, the device server
reboots, causing it to lose the IP
address.
Telnet back to Port 1. Wait for it to
fail, then Telnet to port 9999
again. Make sure you press Enter
within 5 seconds.
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.
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.
To enter Setup Mode via Telnet,
the Enter key must be pressed
within 5 seconds.
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 have
a network connection.
Telnet to port 9999 again and
press Enter as soon as you see
the Press Enter to go into Setup
Mode message.
Confirm that the Ethernet address
that you entered with the ARP
command is correct. The Ethernet
address must 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 does not have a
network connection.
The device server is not
communicating with the serial
device it is attached to.
When you try to enter the setup
mode on the device server via
the serial port, you get no
response.
You can ping the device server,
but not Telnet to the device
server on port 9999.
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.
There may be an IP address
conflict on your network
The Telnet configuration port
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.
Turn the device server off and
then issue the following
commands at the DOS prompt of
your computer:
7-2 Wi232/WiUSB User Guide
(9999) is disabled within the device
server security settings.
ARP -D X.X.X.X (X.X.X.X is the IP o f
the device server).
PING X.X.X.X (X.X.X.X is the IP o f
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.

8. Binary to Hex Conversion
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.
Following are two simple ways to convert binary numbers to hexadecimals.
8.1.1 Conversion Table
Hexadecimal digits have values ranging from 0 to F, which are represented as 09, 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
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

8.1.2 Scientific Calculator
Another simple way to convert binary to hexadecimals is to use a scientific calculator, such as the one
available on Windows’ operat ing s y s tems. Fo r exam p le:
1. On the Windows’ Start menu, click Programs/Accessories/Calculator.
2. On the View menu, select Scientific. The scientific calculator displays.
3. Click Bin (Binary), and type the number to convert.
Click Hex. The hexadecimal value displays.
