OnCell G3100 Series

ATTENTION
If the IP gateway is in GSM/GPRS mode, SIGNAL LEDs will not be illuminated if the phone number or APN is
incorrect. Check the GSM LED if the SIM card is installed correctly.
The GSM LEDs on the front panel provide a convenient way of checking if the SIM card is installed properly. If
the antenna is installed and the network is operating normally, then at least one of the three SIGNAL LEDs
should be illuminated at all times. If none of the GSM and SIGNAL LEDs is illuminated, then the SIM card may
not be installed properly. This is because the PIN code is stored on the SIM card; if the PIN code cannot be
accessed, then the IP gateway will not be accessible over the network.
Connecting the Power
The dual power inputs that connect to the 4-pin power terminal block (2 terminals per power input) can be used
to connect the OnCell G3100 to a variety of field power sources that support 12 to 48 VDC. After connecting the
power wire to the OnCell G3100’s terminal block, the “PWR” LED will glow a solid green color to indicate that the
system is ready.
Connecting the I/O Port
Six terminals on the terminal block are reserved for the I/O ports, with 2 terminals used for each input, and 2
terminals used for the output.
Digital Input
Digital ON and OFF determine which of the 2 electrically isolated inputs are used:
•
+13 to +30 V for state “1” (On)
•
+3 to -30 V for state “0” (Off)
