Figure 2.3 4 Way EBU and ALEC
This diagram shows a system control encoder used in the stand-alone
mode and connected to the master input of the 4 Channel Encoder
Buffer Unit. One follower output is connected to the “Master Encoder”
input on a follower drive (this drive must be in the encoder follower
mode). With this arrangement, the follower encoder follows the
system control encoder, taking into account any gearing, etc.
configured in the drive.
