Change key
Select to modify the current AES encryption key. The default is
N
(No).
Enter key
If you selected
Change Key
, enter the key (at the
Enter Key
prompt) in hexadecimal numbers. Enter 32 characters for 128 bits
key length, 48 characters for 192 bits key length, or 64 characters
for 256 bits key length.
Encryption only applies to the port selected for data tunneling (default 10001),
regardless of whether you are using TCP or UDP.
Generally, one of two situations applies:
Encrypted WiPort NR to WiPort NR device communication. Be sure to configure
both devices with the same encryption key.
Third-party application to WiPort NR -encrypted communication: WiPort NR
device 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 WiPort NR serial-to-Ethernet device server.
Lantronix Secure Com Port Redirector provides an encrypted connection from
Windows-based applications to the WiPort NR device server. Information about
SCPR is at

Enable Enhanced Password
The Enhanced Password setting allows you to set a password of up to 16 characters
for protecting Telnet and Web Page access. We recommend that you select the
Y
(Yes) option and enable the enhanced password setting.
Avoid using either the 4 character basic password setting or no password at all as
they are not secure options.
Enable Enhanced Password (N) ?
Disable Port 77F0 (Hex)
Port 77F0 allows a custom application to query or set the eleven WiPort NR
configurable pins when they are functioning as general purpose I/O (GPIO). Disable
this capability, if desired, for security purposes.
Disable Port 77F0h (N) ?
The default setting, the
N
(No) option, enables GPIO control. The
Y
(Yes) option
disables the GPIO control interface.
Default Settings
Select
7 Defaults
from the Change Setup menu to reset the unit’s Channel 1
configuration, Channel 2 configuration, E-mail settings, and Expert settings to the
factory default settings. The server configuration settings for IP address, gateway IP
address, and netmask remain unchanged. The configurable pins’ settings also
remain unchanged. The specific settings this option changes are listed below.
Note:
Though enhanced password is disabled by default, we recommend
that you always enable the enhanced password setting and create a strong
16 character password. See
