Connections between drives with OPTD2
Special connection:
In this connection example, the leftmost device is the Master and the others are slaves. The Master
can send and receive data from the slaves. The slaves cannot communicate with each other. Changing
of masters is not possible, the first device is always the Master.
The OPTD2 board in the Master has the default jumper selections, i.e. X6:1-2, X5:1-2. The jumper
positions have to be changed for the slaves: X6: 1-2, X5:2-3.
