The TN18EFI board has a set of five DIP switches whose IDs are ID1-ID5 from the
lower bit to the higher bit. Each DIP switch can be used to set a binary digit, 0 or 1.
When the DIP switch is toggled to
0
, the value of the corresponding bit is set to 0. DIP
switches must be toggled to the topmost or the bottommost. Otherwise, the subrack ID
cannot be intuitively identified.
A maximum of 32 states can be set. The value is 00000 by default. "0" indicates the
master subrack. The other values indicate slave subracks. As shown in
, the
value represented by the ID5-ID1 is 00001, which is 1 in decimal system. That is, the
subrack ID is 1.
