Ethernet Control
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.
RF Setup
The Head End sends the control channel at a level of 50 dBmV. In virtually all installations, the system installer has
installed filters to the RF Out connection to match the level to the other RF channels. The manual that was shipped
with the Head End provides more detail, if needed, can be downloaded from the Head End page in the
www.crwww.com Web site.
