Setting the Domain Number
A domain stands for a range of stations in a network connected by control bus. Set the do-
main number in the range of 1 to 31. T
o set a domain number, set the DIP switches as fol-
lows.
• Setting DIP switches
0: In the state shown in the following figure, the switch is tilted toward the left.
1: In the state shown in the following figure, the switch is tilted toward the right.
Bits 2 and 3 must always be zeros (0s).
