GFR-2400M is for a two-way wireless data transmission products and work for the 868 ~ 928 MHz frequency,
mainly to provide two-way wireless transmission.GFR-2400M provide a RS-232 (TTL level) and 485 interface
(CMOS level), as long as the user interface in support of the application of internal and RS-485 or RS-232
communications, will be the standard Serial interface for wireless data transmission. There are several transfer
modes as following:
Broadcasting mode: a transmitter can be connected with all distances in the launch of the GFR-2400M.
Point-to-point transmission mode: through the instructions set, it will send the information required to specify
the ID on the GFR-2400M.
In this paper, a detailed description of GFR-2400M two-way wireless data transmission modules related hardware
interface and instructions for use.GFR-2400M as a complete collection of RF circuit, particularly suited for wireless
products, such as monitoring, scheduling, data transmission, industrial control, wireless meter reading system. It
can also direct as end products, information transmission,
