Hardware Installation of the Raven XE
Rev 1.0 Oct.09 19
Your Raven XE will work with most PCS cellular antennas
with a SMA connector that works in the high and low
frequencies of the cellular technology of your modem. Connect
the primary antenna or primary RF cable directly to the
antenna connector on the back of the Raven XE.
Tip: When using a cable to an antenna placed away from the
modem, minimize the length of your cable. All gain from a more
advantageous antenna placement can be lost with a long cable to the
modem.
Note: Use of receive diversity for
EV-DO is optional. Data trans-
mission and reception may be
adversely affected if it is not
used.
Connecting to Power
The Raven XE digital I/O port consists of a 4 pin power
connector, which includes two digital I/O ports. Port 4 is
software configurable, while port 3 is Digital Input only and
not software configurable.
This I/O port handles external input and output events. An
external device can send digital input to the modem, through
the digital I/O port.

To provide for diversity in the signal reception, connect the
second antenna to the second antenna port (SMA, labeled Rx
Div ANT2) on the back of the Raven XE.
Caution: If you are not using a diversity antenna, you should disable
the receive diversity option. In ACEmanager, in the WAN/Cellular
group, configure RX Diversity.
