When PT2604 receives data transmitted by encoders such as PT2607, it deciphers the 12 address bits and the 6 data bits. The DIN Pin Signal activates the oscillator which in turn decodes the incoming address and data bits. Please note under the Standby Mode, the oscillator is disabled. It is activated only if the DIN Pin is receiving data. PT2604 then compares the address which was received twice in a consecutive manner with its local address. If all the data received match the local address of PT2607, the 6 bits of data are decoded and transferred to the output pins. The VT Pin then is set to “HIGH” to indicate a that transmission is valid until no signal or unmatched address codes are received. Please note the VT Pin is set to “HIGH” only when there is valid transmission, otherwise, it is in “LOW” State. Please refer to the Operation Flowchart diagram.
