EachRS-485address(eachbrain
board) can be daisy-chained to
uptofourEX4s,whoseBoard
IDs will range from zero to three.
A table showing which jumpers

J3: Modular ARC
Expansion Bus
Connects to the
brain board or
expansion board
with the next
lowestBoardID.
J4: Board ID 1
The jumper position of J4
combined with the jumper
position of J5 determines
theBoardID(0-3).Atable

J5: Board ID 2
The jumper position of J4
combined with the jumper
position of J5 determines the
