Address setting procedure via the AS-i line
The following is the procedure for address setting of the master unit via the AS-i line with
EX250-SAS3/-SAS7 (8 inputs / 8 outputs, and address connector – 2 pcs.).
For setting the unit which occupies two slaves (EX250-SAS3/-SAS7), plug the cable jack into the address
which is not to be set (ADDR2 when ADDR1 is set) to disconnect the address from the AS-i line.
