Installation and configuration
Each position's default is OFF. All boards are shipped configured for a single-board system,
not daisy chained, where the board is physically connected to both the MMI and SDI. All boards
must be specifically addressed to be a part of a daisy chain.
MMI end and SDI end
For daisy chains with more than two LMIs, all cards not on the ends must have DIP Switch 2
(SW2), positions 7 and 8, ON. In cases in which there are three LMIs in the daisy chain, LMI
1 and LMI 3 are end cards, each of which have the special function of providing connectivity
to the MMI and SDI, respectively, for the daisy chain. Card 1 is the card at the MMI end,
providing connectivity to the MMI, and must keep SW2, Position 7, OFF. Card 3 is at the SDI
end, providing connectivity to the SDI, and must keep SW2, Position 8, OFF.
LMI 2, in cases such as the above, is an intermediate card, connected to neither the SDI end
nor the MMI end. In daisy chains of more than two cards, all intermediate cards must have
both Positions 7 and 8 of SW2 ON for the system to function properly.
