iRZ ATM3-485 is a three-band (900/1800/2100 MHz) GSM/3G modem designed for data transmission via cellular network. The modem supports HSDPA/HSUPA/UMTS/EDGE/GPRS and TCP/IP protocol stack.

iRZ ATM3-485 automatically connects to the Internet and establishes connection with the server supporting permanent connection with it or scheduled operation. It enables transparent interaction between the target software and the external device connected to the modem. For ease of the modem integration into to the existing data acquisition systems the iRZ Collector customized server application can be used.

The modem is equipped with the RS485 COM port (RS422 interface is also supported) for the connection of the data cable and three additional GPIOs for the external device management. GPIO operations are controlled by SMS.

iRZ ATM3-485 provides communication redundancy by switching to the second SIM card. The modem supports switching to the redundancy server both in case of connection loss with the main server and by the signal from the modem GPIOs or by SMS commands.

The modem is equipped with the watchdog timer and can operate in a wide input voltage and temperature range.

iRZ ATM3-485 is designed for use in data acquisition systems and process control systems, telemetry and telemechanics, as well as in automated power consumption measurement systems.

The modem key features:
  • the support of client and server modes;
  • transparent TCP/IP-to-COM mode;
  • Modbus RTU, ASCII mode;
  • capable to operate with the backup IP address of the server or the backup server;
  • dual SIM operation;
  • CSD mode;
  • sending SMS to a specified number at the loss of connection with the server;
  • various operating modes with the server (always connected, connection on schedule, on phone or by SMS command);
  • automated tracking of the GSM module state and two types of watchdog timers for pending protection;
  • GPIO management by SMS commands;
  • sending SMS to a specified number by GPIO signals;
  • ATM Control setup programme with the visual interface;
  • easy configuration of the modems with similar parameters;
  • the support of the the iRZ Collector customized server software;
  • remote configuration and updating of the embedded software when working with iRZ Collector;
  • fault tolerance at embedded software updating
