1.Communication: It adopt SDT Serial Data Transmission technology, which makes the process of signal transmission between transmitter and receiver not be interfered by the external environment.
2.Show: It shows both sides' working conditions. When transmitter send signals to receiver, corresponding indicator light will blink with audible alarm until receiving feedback from the receiver, then the indicator light return to be normally on and no audible alarm. and it will return to its original state after transmitter give response to this feedback from receiver and then indicator light will be off.[Repeat the same steps, when the Receiver give signal transmission to transmitter. ]
When the main power supply has no power, it will automatically switch to emergency power supply, and the corresponding indicator light will blink to alarm until the main power supply return to normal operations.
4.Light-dimming:Adjust indicator light's brightness as user's requirement.
5.Misoperation alarm:when Operating errors between transmitter and receiver occur, the red corresponding indicator light will blink to give warnings.
6.Fault: when the transmitter or receiver break down or failure to work, user can press the fault button to make signal transmission to inform opposite side.
7.VDR Interface: meets the standard requirements of NMA0183;can connect to recording instruments.
