Hardware Installation of the Raven XE
Rev 1.0 Oct.09 20
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.
Note: When using a DC power
source (such as a solar cell),
Sierra Wireless recommends
placing a fuse (1-2 Amp) on the
line close to the power source to
protect your power source from
possible surges due to shorts or
other line issues. 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.
Warning: Explosion Hazard - Do not disconnect
equipment unless power has been switched off or
the area is known to be non-hazardous.
Connecting to a Computer or other
Device
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.
