• Address setting
The Mux 2700 module operates as a slave device on a multi-point RS-485 serial line. A unique address is therefore
to be specified for each Mux connected to the same serial line. To set the required address, use the first five swit-
ches according to the following table. Please note that the address 0 is reserved and is never to be used.
