CNI2 Operating and Installation Guide
Serial Port Terminal Block TB2
SIM SOCKET CONNECTION
CNI2 products that have a GSM cellular radio require a SIM card (Subscriber Identity Module) to
be installed as shown in the illustration. The gold contacts face towards the connector, and the
notched end must be positioned outwards as shown.
Typical SIM Card
If your CNI2 is equipped with a CDMA radio, then a SIM card is not required. A SIM card should
not be installed into a CDMA configured CNI2.
WARNING - Explosion Hazard
Do not install or remove the SIM card while the circuit is live unless the area is known to be non-
hazardous.
