* NOTE: Disconnect the USB cable before
connecting or removing power from the
Power Connector [1-01d]. This port does not
require power unless insufficient power is
available from the USB Port (< 500 mA).

LEDs indicate modem activity as follows:
Reset Switch forces the RF Modem to reset (or re-boot).
RSSI LEDs indicate the amount of fade margin present in an active
wireless link. Fade margin is the difference between the incoming
signal strength and the modem’s receiver sensitivity.
Standard Type-B USB connector – This port can also be used to
power the XStream-PKG-U unit.
5-12V Power Connector.
The Config Switch provides an alternate way to enter AT Command
Mode. To enter Command Mode at the Modem’s default baud rate:
Simultaneously press the Reset [1-02a] and Config switches;
release the Reset Switch; then after 1 second, release the Config
Switch. The RF Modem then enters AT Command Mode at the
modem’s default baud rate.
Antenna Port is a 50 Ω RF signal connector for connecting to an
external antenna. Connector type is Reverse Polarity (RPSMA)
female. The RPSMA has threads on the outside of a barrel and a
male center conductor.
