The GT-530 is an industrial SMS alarm machine that can send periodic reports of counter values and event notifications via DI trigger in the form of text messages to operators in a timely manner to deal with events. No matter where you are at any time, you can use your mobile phone to grasp the status of remote operations. It also provides an RS232 interface to allow PAC, PC or PLC to receive and send SMS in the most convenient way to provide more flexible applications. Whether it is a machine monitoring application, a vending machine monitoring system, an unmanned machine room monitoring system or a game machine monitoring system, it can be installed and used quickly after just a few simple setup steps. No programming is required by the user. The main function of SMS Utility is to provide customers with the ability to set GT-530 parameters, such as DI type, SMS message to be sent after DI trigger, target phone, event alarm on or off.
This manual describes the GT-530 controller, a 32‑bit ARM7‑based data acquisition and control unit. It outlines the hardware architecture, including CPU, memory, I/O channels, power requirements, and communication modules such as RS‑232 and GSM/GPRS.
The document also covers installation steps, configuration of serial ports, utility software functions, and troubleshooting tips for events like door, window, and smoke detection. Detailed tables list technical parameters for each interface and module.
