connect and communicate over Ethernet networks using the IP protocol family (TCP for
connection-oriented stream applications and UDP for datagram applications).
ATM Machines
CNC Controllers
Data Collection Devices
Automation Control
Data Display Devices/Digital Signage
HVAC Systems
Medical Devices
Oil and Gas Exploration
Security Alarms and Access Control Devices
Telecommunications Equipment
Time/Attendance Clocks and Terminals
Universal Power Supply (UPS) Management Units
Using a method called serial tunneling; the NetDirect encapsulates serial data into packets and
transports them over Ethernet. Using two NetDirect units, connected by a network, virtual serial
connections can extend across a facility or around the world.

For step-by-step instructions on configuring the NetDirect for serial tunneling or for use
with the Com Port Redirector, see the Net Direct User Guide and other user guides on
the distribution CD that came with your product. For additional tech support, see
http://gridconnect.com/customer-service/support
Protocol Support
The NetDirect 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.
Supported protocols include:
ARP, UDP/IP, TCP/IP, BOOTP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for
network communications.
TCP/IP, UDP/IP, and Telnet for connections to the serial port as well as Telnet Com Port
Control.
TFTP for firmware 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 a point-to-point connection.
Additional Features
Modem Emulation: In modem emulation mode, the NetDirect can replace dial-up modems. The
unit accepts modem AT commands on the serial port and then establishes a network connection
to the end device. This arrangement leverages network connections and bandwidth to eliminate
dedicated modems and phone lines.
Built-in Web Server: The NetDirect includes a built-in web server for configuring the unit and
displaying operating and troubleshooting information on the attached links to online support.
Security Features: Password Protection and 256-bit AES Encryption
Configuration Methods
After installation, the NetDirect requires configuration. 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 NetDirect and assigning IP addresses and other configurable settings:
Web Manager: View and configure all settings easily through a web browser using the Web
Manager. See Configuration Using Web Manager.
DeviceInstaller: Configure the IP address and related settings and view current settings on
the NetDirect using a Graphical User Interface (GUI) on a PC attached to a network. You will
need the latest version of DeviceInstaller. See Using DeviceInstaller.
Serial and Telnet Ports: Use Setup Mode, a command line interface. There are two
approaches to accessing Setup Mode: making a Telnet connection to the network port (9999)
or connecting a terminal (or a PC running a terminal emulation program) to the unit's serial
port. See Configuration Via Telnet or Serial Port (Setup Mode)

IP Address
The NetDirect must have a unique IP address on your network. This address references the
specific unit. By default, the unit is DHCP-enabled and automatically assigned an IP address on
DHCP-enabled networks. If you are assigning a static IP address, the systems administrator
generally provides the IP address, subnet mask, and gateway.
Note: The factory default IP address is 0.0.0.0 to enable DHCP, BOOTP, and AutoIP.
When the units boots, it sends a DHCP broadcast to try and get an IP address. If it
receives no reply from a DHCP server, the NetDirect tries BOOTP. If the NetDirect does
not receive a response from BOOTP, it reverts to an AutoIP address.

port is enabled by default.
Note: This feature is not available on single port device servers, since it
can only be applied to channel 1.
Port Settings
Protocol
From the drop-down menu, select the protocol type for the selected
channel. The default setting is RS232.
Flow Control
Flow control manages data flow between devices in a network to ensure it
is processed efficiently. Too much data arriving before a device is
prepared to manage it causes lost or retransmitted data. None is the
default.
Baud Rate
The unit and attached serial device, such as a modem, must agree on a
speed or baud rate to use for the serial connection. Valid baud rates are
300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, and
230400 baud. Additionally, 921600 and 460800 baud rates are available
when CPU is set to High. The default setting is 9600.
Data Bits
Indicates the number of bits in a transmitted data package. The default
setting is 8.
Parity
Checks for the parity bit. The default setting is None.
Stop Bits
The stop bit follows the data and parity bits in serial communication. It
indicates the end of transmission. The default setting is 1.
Pack Control
Enable Packing
Select to enable packing on the NetDirect.
Two firmware-selectable 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.
Disabled by default.
Idle Gap Time
Select the maximum time for inactivity. The default time is 12 milliseconds.
Match 2 Byte Sequence
Use to indicate the end of a series of data to be sent as one group. The
sequence must occur sequentially to indicate end of the data collection to the
NetDirect. The default setting is No.
Match Bytes
Use to indicate the end of a series of data to be sent as one group. Set this
value to 00 if specific functions are not needed.
Send Frame Immediate
After the detection of the byte sequence, indicates whether to send the data
frame or the entire buffer. Select Yes to send only the data frame. The default
setting is No.
Send Trailing Bytes
Select the number of bytes to send after the end-of-sequence characters. The
default setting is None.
Flush Input Buffer (Serial to Network)
With Active Connect
Select Yes to clear the input buffer with a connection that is initiated from
the device to the network. The default setting is No.
With Passive Connect
Select Yes to clear the input buffer with a connection initiated from the

6: Configuration Via Telnet or Serial Port (Setup
Mode)
You must configure the unit so 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 are available from your Grid
Connect 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 explains how to access and use Setup Mode. To complete the configuration,
continue with Chapter 7: Setup Mode: Server Configuration, Chapter 8: Setup Mode: Channel
Configuration and Chapter 9: Setup Mode: Advanced Settings.
Note: The menus in the configuration chapters show a typical device. Your device may
have different configuration options.
Accessing Setup Mode
Telnet Connection
To configure the unit over the network, establish a Telnet connection to port 9999.
Note: You can also use DeviceInstaller to access Telnet. Select the device from the main
window list, and click the Telnet Configuration tab. When the window opens, click the
Connect button. Skip steps 1 and 2.
To establish a Telnet connection:
1. From the Windows Start menu, click Run and type the following command, where x.x.x.x is
the IP address, and 9999 is the unit’s fixed network configuration port number:
Windows:
telnet x.x.x.x 9999

8. When you are finished, save the new configuration (option 9). The unit reboots.
Serial Port Connection
To configure the unit through a serial connection:
1. 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.
2. Reset the NetDirect 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 NetDirect.
At this point, the screen display is the same as when you use a Telnet connection.
Exiting Setup Mode

7: Setup Mode: Server Configuration
This chapter explains how to configure the network settings.
Current values display in parentheses.
Server Configuration (Option 0)
The unit’s basic network parameters display when you select Server configuration (option 0).
The IP Address, Set Gateway IP Address, and Netmask fields display the current values.
Network Settings

IP Address
If DHCP is not used to assign IP addresses, enter the IP address manually. The IP 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.
IP Address : (000) (000) (000) (000) _
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 NetDirect to disable
AutoIP, DHCP, or BootP. To disable an option, set the appropriate bit.
BootP/DHCP/AutoIP options

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.
Set Gateway IP Address
The gateway address, or router, allows communication to other LAN segments. The gateway
address should be the IP address of the router connected to the same LAN segment as the unit.
The gateway address must be within the local network. The default setting is N (No), meaning the
gateway address has not been set. To set the gateway address, type Y and enter the address.
Set Gateway IP Address (N) ? Y
Gateway IP addr (000) (000) (000) (000)_
Netmask: Number of Bits for Host Part
A netmask defines the number of bits taken from the IP address that are assigned for the host
part.
Netmask: Number of Bits for Host Part (0=default) (0) _
Class A: 24 bits; Class B: 16 bits; Class C: 8 bits
The unit prompts for the number of host bits to be entered, then calculates the netmask, which
appears in standard decimal-dot notation (for example, 255.255.255.0) when the saved
parameters display. The default setting is 0.

Set DNS Server IP Address
The DNS server allows the name of a remote machine to be resolved automatically. The default
is N (No), indicating the DNS server address has not been set. To set the DNS server address,
type Y. At the prompt, enter the DNS server address. If the device is DHCP enabled, the DHCP
server provides the DNS server IP address, which will override this configured value.
This setting is applicable only in Manual Connection mode.
Set DNS Server IP addr
((N) ?
Change Telnet Configuration Password
Setting the Telnet configuration password prevents unauthorized access to the setup menu
through a Telnet connection to port 9999 or through web pages. The password must have 4
characters. The default setting is N (No).
Change Telnet/Web Manager password (N) ? _
An enhanced password setting (for Telnet access only) of 16 characters is available under
Security Settings (Option 6) and can be modified or disabled via Web Manager (see
Server Configuration).
You do not need a password to access the Setup Mode window by a serial connection.
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 or Monitor Mode (see
Chapter 11: Monitor Mode).
When you enter Monitor Mode from the serial port with network connection enabled and
issue the NC (Network Communication) command, you see the unit’s IP configuration.
There are three methods for assigning DHCP names to the unit.
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 XX.XX.XX.XX (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).
8: Setup Mode: Channel Configuration
This chapter explains how to configure the serial port.
Current values display in parenthesis.
You must enter some values in hexadecimal notation. See Appendix E: Binary to
Hexadecimal Conversions.
Channel 1 (Option 1)
Select Channel 1 (Option 1) from the Change Setup menu to define how the serial port responds

We recommend that you not use the reserved port numbers for this setting as
incorrect operation may result.
Use Port 0 for the outgoing local port to change with each connection. The port range is 50,00059,999. 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.
Connect Mode
Connect Mode defines how the unit makes a connection, and how it reacts to incoming
connections over the network.
ConnectMode (C0) ? _
Enter Connect Mode options in hexadecimal notation. The default setting is C0.

asserted to asserted.
With a Specific Start
Character
Attempts to connect when it receives a specific start character from the serial
port. The default start character is carriage return.
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 an IP address does not follow the first command string character (which is "C"),
the subsequent character string is interpreted as the host name and domain to
be used in DNS lookup. This character string can include a destination port
number as well. The port number can be preceded by either a forward slash (/) or
a colon ( : ).

Autostart (Automatic
Connection)
If you enable Autostart, the unit automatically connects to the remote IP
address and remote port specified when the firmware starts.
Hostlist
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.

To enable the hostlist:
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.
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.
After completing the hostlist, repeat the previous step if necessary to edit the hostlist again.
For Retrycounter, enter the number of times the Grid Connect 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.
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 10-65535. The default
setting is 250.
d) Datagram Type
Directed UDP
When selecting this option, the prompt requests the Datagram type. Enter 01 for
directed or broadcast UDP. Datagrams of type 01 can be sent as a broadcast by
enabling this option. The default is not to broadcast.
Datagrams are sent as subnet-directed broadcasts.
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 NetDirects, 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).
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
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).
Data Echo & Modem Response
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.
Modem Responses Only
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.

Error
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 a "0" 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.

each new connection.
Remote IP Address
This is the destination IP address used with an outgoing connection.
Remote IP Address : (000) (000) (000) (000)_
This option does not display when Hostlist is enabled from the ConnectMode prompt
(see Connect Mode for more information).
Remote Port
You must set the remote TCP port number for the unit to make outgoing connections. This
parameter defines the port number on the target host to which a connection is attempted.
Remote Port (0) ? _
To connect an ASCII terminal to a host using the unit for login purposes, use the remote port
number 23 (Internet standard port number for Telnet services).
This option does not display when Hostlist is enabled from the ConnectMode prompt (see
Connect Mode for more information).
Disconnect Mode (DisConnMode)
This setting determines the conditions under which the unit will cause a network connection to
terminate. The default setting is 00.
DisConnMode (00) ? _
In DisConnMode (Disconnect Mode), when Modem Control In is not asserted, this
condition either drops the connection or is ignored.

(5) When Ctrl+D or Hex 04 is detected, the connection is dropped. Both Telnet Com Port Cntrl and Disconnect with
EOT must be enabled for Disconnect with EOT to function properly. Ctrl+D is only detected going from the serial port
to the network.
(6) When Modem Control In transitions from a high state to a low state, the network connection to or from the serial port
drops.
Flush Mode (Buffer Flushing)
Using this parameter, you can control line handling and network buffers with connection startup
and disconnect. The default setting is 00.\

Alternate Packing Algorithm (Pack Control)
Enable
1
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.
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-of-sequence
character; this option helps to adapt frame transmission to the frame boundary. The default
setting is 00 (none).
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. The default
setting is 0 (disabled).
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). The default
setting is 0.
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 TCP connection to the local
port 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 (00:00) ?:
To disable the inactivity timeout, enter 00:00. Range is 0 (disabled) to 5999 seconds (99 minutes,
59 seconds). Default setting is 0.
Send Characters
Enter up to two characters in hexadecimal representation in sendchar.
SendChar 1 (00) ? _
SendChar 2 (00) ? _
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 Error! Reference source not found.). The
default setting is 00.
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. The default setting is
all 0s.

TCP Keepalive Time In Seconds
This option allows you to change how many seconds the unit waits during a silent connection
before attempting to see if the currently connected network device is still on the network. If the
unit gets no response, it drops that connection. The default setting is 45.
TCP Keepalive time in s (1s - 65s; 0s=disable):
(45) ?
ARP Cache Timeout In Seconds
Whenever the unit communicates with another device on the network, it adds an entry into its
ARP table. The ARP Cache timeout option allows you to define how many seconds (1-600) the
unit will wait before timing out this table. The default setting is 600.
ARP cache timeout in s (1s - 600s) :
(600) ?
CPU Performance
This option allows you to increase the CPU performance required to use the higher baud rates on
the serial interface (460800 bps and 921600 bps). The default CPU performance mode supports
up to 230400 bps.
CPU performance (0=Regular, 1=Low, 2=High):
(0) ?
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.
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 sequences (only during the
bootup sequence). The default for disabling Monitor Mode at bootup is N (No). See Chapter 11:
Monitor Mode.

Security Settings (Option 6)
You can change security settings by means of Telnet or serial connections only, not on the Web
Manager. We recommend that you set security over the dedicated network or over the serial
setup to prevent eavesdropping.
Caution:
Disabling both Telnet Setup and Port 77FE will prevent users from
accessing the setup menu from the network. Disabling Port 77FE also
disables the Web from configuring the device.

Enable Encryption
Rijndael is the block cipher algorithm chosen by the National Institute of Science and Technology
(NIST) as the Advanced Encryption Standard (AES) to be used by the US government. The
NetDirect supports 128-, 192-, and 256-bit encryption key lengths.
Note: Configuring encryption should be done through a local connection to the serial port
of the NetDirect, or via a secured network connection. Initial configuration information,
including the encryption key, is sent in clear text over the network.
To configure AES encryption on the NetDirect:
Enable Encryption (N) Y
Key length in bits (0): 128
Change Keys (N) Y
Enter Keys:
**-**-**-**-**-**-**-**-**-**-**-**-**-**-**-**
1. When prompted to enable encryption, select Y.
2. When prompted, enter the encryption key length. The NetDirect supports 128-, 192-, and
256-bit encryption key lengths.
3. When prompted to change keys, select Y.
4. At the Enter Keys prompt, enter your encryption key. The encryption keys are entered in
hexadecimal. The hexadecimal values are echoed as asterisks to prevent onlookers from
seeing the key. Hexadecimal values are 0-9 and A-F.
For a 128-bit key length, enter 32 hexadecimal characters.
For a 192-bit key length, enter 48 hexadecimal characters.
For a 256-bit key length, enter 64 hexadecimal characters
5. Continue pressing Enter until you return to the Change Setup menu.
6. From the Change Setup menu, select option 9 to save and exit.
Encryption only applies to the port selected for data tunneling (default 10001), regardless of
whether you are using TCP or UDP.
Generally, one of these situations applies:
Encrypted NetDirect-to-NetDirect communication. Be sure to configure both NetDirect devices
with the same encryption key.
Third-party application to NetDirect-encrypted communication: NetDirect uses standard AES
encryption protocols. To communicate successfully, products and applications on the peer side
must use the same protocols and the same encryption key as the NetDirect.
Secure Com Port Redirector provides an encrypted connection from Windows-based
applications to the NetDirect. Information about SCPR is at
http://www.lantronix.com/support/downloads/?p=SCPR. A 30-day trial version of SCPR is
available.
Note: Developers can license the Encryption Library Suite.
See http://www.lantronix.com/support/downloads/?p=ELSUITE.
Enable Enhanced Password
This setting defaults to the N (No) option, which allows you to set a 4-character password that
protects Setup Mode by means of Telnet and web pages. The Y (Yes) option allows you to set an

10: Firmware Upgrades
Obtaining Firmware
You can obtain the most up-to-date firmware and release notes for the unit from the Lantronix
web site. Do not change firmware unless directed by Technical Support.
Reloading Firmware
There are several ways to update the unit's internal operational code (*.ROM): using
DeviceInstaller (the preferred way), using TFTP, or using the serial port. You can also update the
unit's internal Web interface (*.COB) using TFTP or DeviceInstaller.
Here are typical names for those files. Check the Grid Connect web site for the latest versions
and release notes.
Firmware Files
ROM File
COB
xDirect_6900.rom
xDirect_webm_2000.cob
Please refer to the DeviceInstaller online Help for information about reloading firmware using
DeviceInstaller. The other methods are discussed below.
Using TFTP: Graphical User Interface
To download new firmware from a computer:
Use a TFTP client to send a binary file to the unit (*.ROM to upgrade the unit's internal
operational code and *.COB to upgrade its internal Web interface).
TFTP requires the .ROM (binary) version of the unit's internal operational code.
In the TFTP server field, enter the IP address of the unit being upgraded.
Select Upload operation and Binary format.
Enter the full path of the firmware file in the Local file name field.
In the Remote file name field, enter the current internal operational code (U5) or WEB1 to WEB6
for the internal Web interface.
Click the Upload Now button to transfer the file to the unit.
After the firmware has been loaded and stored, which takes approximately 8 seconds to
complete, the unit performs a power reset.
Using TFTP: Command Line Interface
To download new firmware from a computer:
Enter the following from a TFTP command line interface:
tftp –i <ip address> put <local filename> <destination file name>
The following examples demonstrate the TFTP command sequence to download the .rom file and
the .cob file:
tftp –i 192.168.1.111 put xDirect_6900.rom U5
tftp –i 192.168.1.111 put xDirect_webm_2000.cob WEB1
Recovering the Firmware Using the Serial Port and DeviceInstaller
If for some reason the firmware is damaged, you can recover the firmware file by using
DeviceInstaller to download the *.ROM file over the serial port.
To recover firmware:
Start DeviceInstaller. If your PC has more than one network adapter, a message displays. Select
an adapter and click OK.
From the Tools menu, select Advanced/Recover Firmware. The Serial Port Firmware Upgrade
window displays.
For Port on PC, enter the COM port on the PC that is connected to the serial port of the Grid
Connect unit.
For Device Model, be sure the appropriate device (e.g., NetDirect) displays.
For Firmware File, click the Browse button and go to the location where the firmware file
resides.
Make sure the NetDirect on which you are recovering firmware is connected to this
selected port on your PC.
Click OK to download the file.
When prompted, reset the device. Status messages and a progress bar at the bottom of the
screen show the progress of the file transfer. When the file transfer completes, the message
“Successful, Click OK to Close” displays.
Click the OK button to complete this procedure.
For more information, see Recovering Firmware in the DeviceInstaller online Help.
11: Monitor Mode
Monitor Mode is a command-line interface used for diagnostic purposes. There are two ways to
enter Monitor Mode: locally using the serial port or remotely using the network.
Entering Monitor Mode Using the Serial Port

14: Alternative Ways to Assign an IP Address
Earlier chapters describe how to assign a static IP address using DeviceInstaller, Web Manager,
and Setup Mode (through a Telnet or serial connection). This section covers other methods for
assigning an IP address over the network.
DHCP
The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP
server exists on the network, it provides the unit with an IP address, gateway address, and
subnet mask when the unit boots up.
You can use the DeviceInstaller software to search the network for the DHCP-assigned IP
address and add it to the list of devices retrieved.
Note: This DHCP address does not appear in the unit’s Setup Mode or in Web Manager.
You can determine your unit’s DHCP-assigned IP address in Monitor Mode. When you
enter Monitor Mode from the serial port with network connection enabled and issue the
NC (Network Communication) command, you see the unit’s IP configuration.
AutoIP
The unit ships with a default IP address of 0.0.0.0, which automatically enables
Auto IP within the unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address
automatically in smaller networks that may not have a DHCP server. A range of IP addresses
(from 169.254.0.1 to 169.254.255.1) has been explicitly reserved for AutoIP-enabled devices. Do
not use this range of Auto IP addresses over the Internet.
If your unit cannot find a DHCP server, and you have not manually assigned an IP address to
it, the unit automatically selects an address from the AutoIP reserved range. Then, your unit
sends out a (ARP) request to other nodes on the same network to see whether the selected
address is being used.
If another device is using the selected IP address, the unit selects another address from the
AutoIP range and reboots. After reboot, the unit sends out another ARP request to see if the
selected address is in use, and so on.
AutoIP does not replace DHCP. The unit continues to look for a DHCP server on the network. If it
finds a DHCP server, the unit switches to the DHCP server-provided address and reboots.
Note: If a DHCP server is found, but it denies the request for an IP address, the unit does
not attach to the network, but waits and retries.
AutoIP can be disabled by setting the unit’s IP address to 0.0.1.0. This setting enables DHCP but
disables AutoIP.
BOOTP
Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a specific
duration of time.
ARP and Telnet
If the unit has no IP address, you can use Address Resolution Protocol (ARP) method from UNIX
and Windows-based systems to assign a temporary IP address.
To assign a temporary IP address:
1. On a UNIX or Windows-based host, create an entry in the host's ARP table using the
intended IP address and the hardware address of the unit (on the product label on the bottom
of the unit).
arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)
arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)
Note: For the ARP command to work on Windows 95, the ARP table on the PC must
have at least one IP address defined other than its own.
2. If you are using Windows 95, type ARP -A at the DOS command prompt to verify that there
is at least one entry in the ARP table. If the local machine is the only entry, ping another IP
address on your network to build a new entry in the ARP table; the IP address must be a host
other than the machine on which you are working. Once there is at least one additional entry
in the ARP table, use the following command to ARP an IP address to the unit:
arp -s 191.12.3.77 00-20-4a-xx-xx-xx
3. Open a Telnet connection to port 1. The connection fails quickly, but the unit temporarily
changes its IP address to the one designated in this step.
telnet 191.12.3.77 1
4. Open a Telnet connection to port 9999, and press Enter within five seconds to go into Setup
Mode. If you wait longer than five seconds, the unit reboots.
telnet 191.12.3.77 9999
Note: The IP address you just set is temporary and reverts to the default value when the
unit’s power is reset, unless you configure the unit with a static IP address and store the
changes permanently.
15: Binary to Hexadecimal Conversions
Many of the unit's configuration procedures require you to assemble a series of options
(represented as bits) into a complete command (represented as a byte).
The resulting binary value must be converted to a hexadecimal representation.
Use this chapter to learn to convert binary values to hexadecimals or to look up hexadecimal
values in the tables of configuration options. The tables include:
Command Mode (serial string sign-on message)
AES Keys
Converting Binary to Hexadecimal
Following are two simple ways to convert binary numbers to hexadecimal notation.
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,
treat the upper and lower four bits separately to produce a two-digit hexadecimal number (in this
case, 4C). Use the following table to convert values from binary to hexadecimal.
Scientific Calculator
Another simple way to convert binary to hexadecimal is to use a scientific calculator, such as the
one available on the Windows operating systems. For example:
1. On the Windows Start menu, click Programs -> Accessories -> Calculator.
2. On the View menu, select Scientific. The scientific calculator appears.
3. Click Bin (Binary), and type the number you want to convert.
Figure A-1 Windows Scientific Calculator
4. Click Hex. The hexadecimal value appears.
