The address pins are usually preset to transmit data codes with particular security codes by the DIP switches or PCB

wiring, while the data is selected using push buttons or electronic switches.

The following figure shows an application using the HT680:

²¾² is a dummy code which is left ²open² and not bonded out.

²² is a dummy code which is set low and not bonded out.

Transmission Enable

For the TE trigger type of encoders, transmission is enabled by applying a high signal to the TE pin. But for the Data

trigger type of encoders, it is enabled by applying a high signal to one of the data pins D12~D15.
