Introduction
 

Overview
The OnCell G2150I is an isolated quad-band GSM/GPRS modem that transmits data and short messages (SMS) over GSM/GPRS mobile networks. It can be used to improve the efficiency of maintenance and communication, independent of operating skill.

Industrial Form Factor
The OnCell G2150I is housed in an IP30 enclosure that can be mounted on a DIN-rail or on the wall. It has a 12 to 48V DC power input, allowing different types of field power sources to be attached.
The serial ports are also protected by 2 KV isolation, so the system is safe from ground loop currents.

Quad-band GSM/GPRS Communication
While GSM-900 and GSM-1800 are used in most parts of the world, GMS-850 and GSM-1900 are used by operators in the United States, Canada, and many other countries in the Americas. With quad-band cellular modems such as the OnCell G2150I, administrators do not have to go through the trouble of selecting different models for different parts of the world.


Signal LED Indicators
The OnCell G2150I provides several LED indicators for basic status information. At a glance, users can see the signal strength and the current mode of communication, such as CSD data or GPRS.
