Multiple AD824 Connection
The next example shows how the AD824 COM ports can be used to connect several
AD824s in combination with a DME32. The COM PC/RS422 port on the AD824 #1 is
connected to the COM port on the DME32, while the COM RS422 port on AD824 #1
is connected to the COM PC/RS422 port on AD824 #2. The COM PC/RS422 switches
on both AD824s are set to RS422. The DME32 is the wordclock master and both the
AD824s receive their wordclocks via their SLOT inputs.
