3.1.2.1 Front
On the front of the IPnXGii is the RS232 (COM2) port, CFG Button, RSSI, Tx, RX, CELL & CPU LED’s as
described below:
The
RS232
port is used for serial communication to serial
based end devices. (300bps to 921kbps)
CONFIG (Button) -
Holding this button depressed while
powering-up the IPnXGii will boot the unit into FLASH FILE
SYSTEM RECOVERY mode. The default IP address for
system recovery (only - not for normal access to the unit) is
static: 192.168.1.39.
If the unit has been powered-up for some time (>1 minute),
depressing the CFG Button for 8 seconds will result in FAC-
TORY DEFAULTS being restored, including the static factory
IP address. This IP address is useable in a Web Browser for
accessing the Web User Interface.
Tx(Red)/Rx(Green) LED’s -
The Tx/Rx LED’s indicate car-
rier (cellular) traffic. Also, during system bootup, the RF &
SGNL LED’s will flash.

As the received signal strength increases,
starting with the furthest left, the number of active
RSSI LEDs increases.
CPU LED -
The Status LED indicates that power has
been applied to the module. Flashing indicates boo-
