ICE-HE Ethernet Head End
Ethernet Connection
The ICE-HE typically communicates over a network using a static IP address, and is shipped set to a
default address:
IP Address: 192.168.1.251
Subnet Mask: 255.255.255.0
Gateway Address: 000.000.000.000
Odds are, at least the IP address will need to change when the ICE-HE is connected to the client’s
network. One your first steps will be to obtain a static address from the client’s IT department, as well
as an external gateway IP address if you intend on supporting the system from your office or anywhere
outside the site’s firewall.
Once you change the settings, create a label noting the settings and attach to the back of the ICE-HE.
Reset IP Address
If you change the default address and forget what it is later on, you can always reset the ICE-HE back
to the default settings using the unit’s front-panel DIP switch 2. While the power is on, flip the switch
off, then back on to reset the IP address. The IP and Subnet Mask will revert, the Gateway will stay at
its current setting.
Since its possible another network device is using the default IP address, the best approach is to enter
the new settings offline, outside the network –and you’ll need a static address approved by the IT
team.
Currently, we’ve removed the
Java
applet we used to use for Web page setup, and will be replacing
that with a simpler, Java-free Web page. Existing units will have the standard Home page and the Java
applet. But new versions of Java may not let you use the app.
For now, use a Terminal app to change the IP address over RS-232.
Changing the IP address via RS-232
You can communicate with the ICE-HE with a Terminal app. If you don’t have one, download Tera
Term, a free (and safe) app.
Settings are: 19200 baud, 8 bits, no parity, 1 stop bit, no flow control
For Tera Term, you define the COM port then after you connect, go to
Setup/Terminal
to turn on
local echo, go to
Setup/Serial
to for port settings.
Use the IP command by itself to see current settings, and then enter the settings you need.
You could use Telnet, Port 2728 – but it’s easier to change the network settings without getting into the
network hassles in the first place.
