FM1125 – RS232 + RS485

FM1125 is light real-time tracking terminal with GPS/GLONASS, GSM connectivity, RS232 and RS485 data interface support, which is able to collect device coordinates and other useful data and transfer them via GSM network to server. This device is perfectly suitable for applications where location acquirement of remote objects is needed: fleet management, car rental companies, taxi companies, public transport, logistics companies, personal cars and so on. In case of losing connection FM1125 can store up to 50 000 records (60 days), and once the connection is established the device will send stored data via GPRS. So you won’t lose your data (coordinates, sensors data and etc.).
