2. Connect a cable from the RJ-45 adapter to the nearest
unit's RS232 In connector.
3. Connect this first unit's RS232 Out connector to the
next unit's RS232 In connector.
4. Continue in this way until all units are connected.
✎
The order in which you connect the units is not
important. You can connect them in any order that
is convenient and keeps the cable lengths to a
minimum.
From the first unit, connect RS232 Out to the next unit's
RS232 In. Continue in this way until all units are in the
loop. The order of units in the loop does not matter because
each unit in the array must have a unique address.
✎
The loop-through limit is approximately 30 units in
typical situations. However, if the units are spaced
far apart or the total length of the loop-through is
very long, this limit may be reduced. You may
need multiple RS232 sources.
For information about configuring RS232 communica-
tions, see "Serial Port Settings" on page 61.
