Changing the IP Address and network settings - Cypress Default
1. Install the Lantronix “WiPort Device Installer” software from the distribution CD or Lantronix
web site (www.lantronix.com).
2. It will be necessary to have an 802.11 Wireless router if any of the network settings are to be
changed. It may also be necessary to temporarily change some of the network settings on the
computer and router that will be used for configuring the Duprex units.
3. Set the Computer TCP/IP address to the same subnet (192.168.1.xxx) as the Duprex units.
Any address except 58 and 59 will work.
4. Set the Wireless Router (access point) to the same subnet (192.168.1.xxx) . The access point
should also have the following settings:
SSID = LTRX_IBSS
Channel = 11
Encryption = Disabled
Mode = Open System (anyone can connect)
5. Apply power to the device(s) being configured.
6. Start the software and follow the procedures in the “Setting IP Address - DPX-7212 Section”
7. If the TCP/IP address of the Remote is changed, then the Central unit must change the
Remote IP address setting in the Channel 1 setup menu. This setting is left at 0.0.0.0 in the
Remot e Channel 1 configuration.
8. Select the Central unit from the Device Installer menu and click on the Telnet button.
This will open a text window for the Telnet session. Press the Enter key.
9. Press the Enter key again, and a list of options will be displayed. Select Option #1 (Channel 1)
Press enter to go through the menu options until “Remote Port” is displayed.
10. Enter the TCP/IP address that will be used for the Remote unit in dot notation.
11. Press Enter key to finish menu options.
12. Select Option #9 “Save and Exit”
Communication and network settings can be changed through the Telnet interface.
Other than the Remote IP address setting it should not be necessary to change the other settings.
For reference purposes, Refer to Table #1 for the Cypress Factory Default settings.
If for some reason the settings are placed into an undefined state, the Reset to factory defaults
jumper can be used to return the units to a know operational condition.
This method connects to the Duprex units using the Cypress Default settings.
