A three-band (900/1800/2100 MHz) iRZ TU31 3G modem is designed for data transmission over 2G and 3G cellular networks.

The iRZ TU31 3G modem is oriented on payment terminals and vending machines. A widespread USB 2.0 interface enables the direct modem connection to a computer without an AC power adapter.  Besides, the modems find a use in industrial applications with one of the most common physical interfaces - RS232. The device can be powered via the TJ6-6P6C connector as needed.

iRZ TU31 supports the main communication functions: data transmission by HSPA+/UMTS/EDGE/GPRS/CSD technologies, fax and SMS send and receive. The modem control is realised by the standard AT commands, as well as by a proper AT command set. The built-in watchdog timer prevents from the device hanging up.

High-speed data transmission, extended temperature range and a compact case provide the use of iRZ TU31 in various industrial applications: vending trade systems, payment terminals, telemetry and telemechanics, data acquisition systems, as well as in different systems requiring high-speed wireless data transmission.
