reboot and the new IP address will be ready to be accessed.
Selecting DHCP from the IP Setup page allows a DHCP server to provide IP address, Subnet Mask and
Gateway information to the iPIO. Click Save and then Reboot when prompted by the button in the left
column. The iPIO will reboot. After reboot, access the iPIO with the IP address assigned by the DHCP
server. Check your DHCP server to identify the IP address assigned to the iPIO. If no IP address is
assigned by a DHCP server, the original IP address will be retained.
Port Settings
The Network Setup page also allows for changing of the port assignment for HTTP, HTTPS and inter-iPIO
protocols. Dataprobe recommends changing the Web port for units that will be connected to the Internet.
This will minimize the number of hacker attacks that the iPIO will be subject to. If a port other than the
default Port 80 is used for web browser access, the port must specifically be used in the URL when
accessing the iPIO. For example, if the Web Port is changed to 9090 then the URL for the unit would be
http://192.168.1.254:9090.
Default Port Assignments
• Web: 80
• Telnet: 23
• DxP: 9100
Telnet
The Telnet setup capabilities can be enabled or disabled with this checkbox
AES Encryption
Pairs of iPIOs can use 128 bit AES encryption to secure status and control messages. To use AES, enter an
AES Passphrase (up to 16 characters) and enable AES with the checkbox. Any additional iPIO that
connects to this device will need to use the same Passphrase as set here. See Remote Setup for entering
the Passphrase of a remote iPIO.
Use DxP Credentials
Older DxP supported devices do not use username and password pairs in the protocol. Uncheck this to
provide backward compatibility if the remote site units do not support U/P pairs.
Connection Timeout
The Telnet and web login will automatically log off the user if no activity is detected for the period of time (in
minutes) specified here. Set to 0 to allow unlimited timeouts, but be sure to log out manually as unlimited
timeout will prevent new users from logging in if the session is not closed manually.
