iRZ ATM2-485 is a dual-band (900/1800 MHz) GSM/GPRS modem developed for data transfer over cellular networks. The modem supports GPRS class 10 and TCP/IP protocol stack.
iRZ ATM2-485 automatically connects to GPRS network and establishes a connection with the server and then maintains a permanent connection to it or runs by schedule. The user gets transparent inter-working between back-end software and an external device connected to the modem. iRZ ATM2-485 is intended to operate in conjunction with a specialized iRZ Collector server.
The modem is equipped with the combined RS485/RS422 serial port for a data cable (part of terminal connector) and three additional GPIO pins used to drive external devices. The operation of the GPIO pins is controlled using SMS messages.
Features:- client and server modes support;
- TCP/IP-to-COM transparent mode;
- Modbus RTU mode, ASCII;
- the ability to operate with standby IP-address of the server or a standby server;
- 2 SIM cards support;
- CSD mode;
- sending SMS message to a specified number when a connection to the server is lost;
- various server operation modes (always connected, connecting according to the schedule, a call or a SMS command);
- automatic tracing of a status of the GSM module and two types of watchdog timers for protection against hangup;
- RS485/RS422 interfaces and 3 x GPIO (including a power output of up to 500 mA with the possibility to power supply from third-party equipment);
