... The 3 series of encoders begins a three-word transmission cycle upon receipt of a transmission en- able (TE for the HT600/HT640/HT680 or D12~D17 for the HT6187/HT6207/HT6247, active high). This cycle will repeat itself as long as the transmission enable (TE or D12~D17) is held high. Once the transmission enable falls low, the encoder output completes its final cycle and then stops as shown below ...
