On the front of the Bullet is the CFG Button, USB Port, Main, GPS & Diversity, GPS & WIFI Antenna
Connectors and SIM Card Slot. The top of the Bullet are the status indicators, RSSI, Tx, RX, GPS and

The USB port is a future development to be available in later releases of firmware.
CFG (Button) - Holding this button while powering-up the Bullet will boot the unit into FLASH FILE SYS-
TEM RECOVERY mode. The default IP address for system recovery (only - not for normal access to the
unit) is static: 192.168.1.39. Hold for 1 second for httpd recovery mode, 5 seconds for tftp recovery mode,
or 10 seconds for master reset. If button is held for longer than 15 seconds the button will be ignored.
If the unit has been powered-up for some time (>1 minute), depressing the CFG Button for ~10 seconds
(unit will reboot) will result in FACTORY DEFAULTS being restored, including the static factory IP address.
This IP address is useable in a Web Browser for accessing the Web User Interface.
Receive Signal Strength Indicator (RSSI) - As the received signal strength increases, starting
with the furthest left, the number of active RSSI LEDs increases.
Tx(Red)/Rx(Green) LED’s - The Tx/Rx LED’s indicate carrier (cellular) traffic.
