Contemporary Research 8 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 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 change, 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. You can use one of two, requiring one of two offline
options:
1. Direct PC Connection. Use an Ethernet ―Crossover‖ cable to make a direct connection to the
ICE-HE Ethernet port and your PC. Two pairs of wires are reversed at one end to create a direct
send/receive path for data.
2. Hub or Switch Connection. Another approach for connection is to use a standard Ethernet hub
or switch between your computer and the ICE-HE. Using standard Cat5 Ethernet cables,
connect your PC to one port, then connect the ICE-HE to the second port.
RS-232 and Telnet Terminal Communication
You can communicate with the ICE-HE with HyperTerminal using an RS-232 or TCP/IP connection to
Port 2728. This can be a more flexible tool than the Web Server, because you can view and change IP
address information, as well as cross-check iC-Net devices and RF receive levels.
