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.

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.
