2.6.4 BiSS / EnDat Encoder

The BiSS / EnDat Encoder is a macro (M12). This header is a common interface for both EnDat and BiSS encoders. Figure 2-9 shows the External Interface Header (H6) and how it interfaces with only digital signals. If the BiSS / EnDat encoder have Sin-Cos analog signals, connect them to the Sin-Cos Encoder Interface Header (H4).
