Software Device Configuration
Windows
Windows device configuration is performed through the “SeaLink Configuration” utility provided with the software
installation. When started, the utility will display all devices on the local network (the utility cannot see devices on
the other side of a router). If your device is not listed, verify that it is connected to the network (see the section
Troubleshooting). To assign static IP addresses, select your device in the list, then uncheck the box that says
“Enable DHCP” and change the “IP”, “Gateway”, and “Network Mask” fields to values valid on your network.
Then click “Apply Changes”. The device will reboot and temporarily disappear from view, so you may need to click
“Search Again” to relocate the device.
Web Configuration
Once the device has been assigned an IP address reachable from your computer, you can configure it through the
onboard web server. Open a web browser such as Internet Explorer or Netscape and type “
http://x.x.x.x
” into the
URL field, where “
x.x.x.x
” is the device’s IP address. The web interface provides a summary page that lists various
details about the device, a port settings page that allows you to configure aspects of each individual serial port, and
an administration page that lets you change the device’s network and password settings.
Security
The password you can set from the Administration page currently applies to the Web Configuration only. The web-
based settings have been identified as a key area where security is important, since users do not need to install
software to modify settings.
Port Defaults
The Port Settings page allows you to set defaults to which each serial port will be set when first opened. If you are
using a virtual serial port protocol such as SeaLink or Tactical Software, programs may change these settings
dynamically after opening the ports. If you want programs to always use the defaults you set, check the box labeled
"Always use defaults". This can be useful especially when specifying a custom baud rate that is not available from
your operating system (see Custom Baud Rates).
Custom Baud Rates
From the Port Settings Page, you can enter a baud rate of any value from 1 to 921600. While it may not be possible
to hit the exact desired baud rate, the Uart will attempt to set it as closely as possible and will be within an
acceptable 2% range. After you click Submit, the page will refresh and display the baud rate actually being used.
RS Modes
The Port Settings page allows you to specify the RS mode for a given port. This may not be the best way to
configure RS modes in all situations (see the section SeaLink Protocol::Configuration). However, if you are using a
protocol that does not allow you to configure the RS mode, you must set the RS mode here.
In all cases, the RS mode must be set in software as well as hardware. See the section Electrical Interface Selection
for details on configuring the hardware.
Resetting to Factory Defaults
If you have forgotten your password or otherwise wish to reset the device to the factory defaults, manually browse
to "
http://x.x.x.x/debug.htm"
(where x.x.x.x is the device's IP address)
and click the button marked "Reset to Factory
Defaults". You will be prompted for a username and password. For the username, enter "debug". In the password
field, type the MAC address of the unit, located either on the summary page or on the label on the device. The MAC
address should be entered without formatting such as dashes or spaces.
