Product Description

Our GDSC05 low power SCADA radio modem, is a 1.5W output power transceiver used for embedded wireless data communications. It has lower output power and low cost as well. It is ideal for embedded remote control applications where the communication ranges several miles.

The digital transmission module is connected to the master station computer via an RS-232 interface, and is connected to the RTU at slave end via an RS-485, RS-232 or TTL interface. It can be used in the field to form a mobile data terminal and its multi over the air rate allows for maximum flexibility.
