Enable Enhanced Password; Disable Port 77F0 (Hex); Defaults - GridConnect NET485 Manual

Third-party application to NET485-encrypted communication: NET485 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 NET485.
Lantronix Secure Com Port Redirector provides an encrypted connection from Windows-based
applications to the NET485. Information about SCPR is at
http://www.lantronix.com/device-networking/software-services/scpr.html
Note: Developers can license the Lantronix Encryption Library Suite. See http://www.lantronix.com/device-
networking/utilities-tools/.

3.10.10 Enable Enhanced Password

This setting defaults to the N (option), which allows you to set a 4-character password that protects the
Configuration Menu via Telnet and Web pages. The Y (Yes) option allows you to set an extended security
password of 16-characters for protecting Telnet and web page access.

3.10.11 Disable Port 77F0 (Hex)

Port 77F0 is a setting that allows a custom application to query or set the three NET485 configurable pins
when they are functioning as general purpose I/O (GPIO). You may want to disable this capability for
security purposes. The default setting is the N (No) option, which enables GPIO control. The Y (Yes) option
disables the GPIO control interface.
Note: The function of the configurable pins on the NET485 should be changed with caution. Some of the configurable
pins are not connected or used for other functions.

3.11 Defaults

Select 7 to reset the unit's Channel 1 configuration, email settings, and expert settings to the 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 that this option changes are listed
below:
Note: If you use default settings, the NET485 will not work properly. You must change the serial port setting for the
NET485. See I/F (Interface) Mode on page 3-12.
