Setting of frequency, interface, and data format

 

Before using DS-303, users can use our software to setting frequency value, interface rate and data format.

 

A. Users can program any frequency value in the frequency range. Before ordering, clients need confirm the frequency range.

 

B. Users can choose the interface rate according to requirement.

 

C. Users can change the data format individually.

 

 

Supported protocol and Transmit capability

 

DS-303 transceivers offer transparent protocol to support various applications and protocols of users.

 

If the user needs to decrease his cost or ease the workload of terminal CPU, we can add other specific functions based on the transparent protocol, such as addressing, data acquisition, command interpretation and so on.

 

Description of Indicator light

 

a. The red and green lights will keep on about 50Ms when power supply.

b. The red light is normally on when transmitting data, while the red light will crush out after ending the data.

c. The green light is normally on when receiving the air signal, while the green light will crush out after receiving the air signal.
