Wireless modem for serial data transmission 'GTR-920F'

Low cost and energy-saving! Introducing a small radio device capable of communication over a distance of 1200m, with a maximum of 2 relay stages.

The "GTR-920F" is a low-power data transmission wireless device operating in the 920MHz band. The child station can also serve as a relay station, enhancing reliability with multi-hop and redundant network configurations. Additionally, it operates on a 12V power supply with a low current consumption of 4 to 30mA, making it suitable for outdoor measurements using solar power and batteries. Its lightweight, waterproof resin case and low power consumption allow for smaller solar panels and batteries, making it useful in areas where laying communication cables is difficult due to steep terrain. 【Features】 ■ Communication range of 1200m in line of sight, with up to 2 levels of relaying (parent → relay 1 → relay 2 → child) ■ Communication interface can be selected between RS-232C and RS-485 using an internal dip switch ■ Can be connected to PCs and various data loggers ■ Communication speed for RS-232C and RS-485 is fixed at 9600bps ■ Capable of sending and receiving long packets of text or binary data under 4095 bytes *For more details, please refer to the related links or feel free to contact us.
