12 Appendix C – Understanding Clock/Data, AC, D2, and BR
It is important to understand clock and data priorities when using a dual transmitter. Table 21 describes the possible settings for Channel 1 and Channel 2 Internal
Clock, Clock Free, Dual Input Data, Clock Free Bit Rate, External Clock, External Data, and Automatic Carrier Output, and the resulting RF output.
Clock and data logic (where they come from and how they are selected) is shown in Figure 55.
The D2 option and command simply allow a second, separate clock free input stream. Refer to section 4.2.3.1.8 for D2 command details. Refer to Figure 55 for
dual input data/clock logic stream.
For details about specific commands, refer to AC, BBCK, BR, CF, or IC.
