12.12.3. Number of devices in switch chains
In a pure MGB switch chain a maximum of ten devices can be connected in series. In mixed switch chains (e.g. MGB
together with CES-AR) the maximum number of devices is also ten.
12.12.4. Resetting in switch chains
Important!
Use the reset input (RST) for resetting in AR switch chains. All devices in the chain must be
reset simultaneously. Resetting individual switches will result in faults.
