Hardware Installation of the Raven XE
Your Raven XE can be used with either DC or AC, with the appropriate power adapter. DC cables and AC adapters are available as optional accessories in addition to the one included with your Raven XE.
The DC power cable positive lead should be connected to the battery or power source positive terminal. The power cable negative lead should be connected to the battery or power source negative terminal.
Tip: The DC power cable has a white wire lead in addition to the power positive and negative. This is for a feature not present in the Raven line modems. In the Raven XE, the white wire lead has no function and can be ignored.

Figure 4-3: Ethernet
The Ethernet port of your Raven XE can be connected directly to a computer or other Ethernet device with either a cross‐over cable or a straight‐through cable. The Ethernet port on the Raven XE is auto‐sensing and connects at 100baseTX. If you are connecting the modem to a hub or switch you should use a straight through cable or use the uplink port on the hub or switch with a cross‐over cable.
Tip: On some computers, the TCP receive window may be set to 16 kbytes. To optimize the throughput of your Raven XE, it is recom- mended that you change the TCP window to 128 kbytes to 256 kbytes using a TCP Optimizer.
