Before beginning, please carefully
note:
CAUTION: STATIC ELECTRICITY
MAY DAMAGE THE IQ-PIP-USP2/CN
MODULE.
Use caution when han-
dling the unit. Carefully ground your-
self BEFORE touching the IQ-PIP-
USP2/CN module. Avoid unneces-
sarily touching the components or
solder pads on the circuit boards.
3.1 Prepare the PIP
1. Set the IQ address switch S1 ..... By
giving each IQ component a
unique address, it can be
individually controlled and
monitored. Whenever the IQ
System wants to send a command
to just one IQ component, it first
sends its address and then the
command down the IQ Bus.
S1 has eight segments because it
actually contains eight tiny
switches inside. The word “ON” is
printed on the switch along its
upper left side to indicate the ON
position and the switches are
numbered along the bottom
(Figure 3.1).
Each of the eight switches in S1
has a value which doubles as the
switch number increases. For
example switch 1 has a value of 1;
switch 2 has a value of 2; switch 3
has a value of 4; switch 4 has a
value of 8 and so on.
The address is determined by
adding the values of all “ON”
switches. In Figure 3.1, switches
1, 3, 4 and 7 are on. Simply add the
values to find the address:
1+4+8+64=77.
A convenient series of IQ address
tables are included in Section
10.9. The tables show the switch
settings for all 250 addresses.
No two IQ components of the
same type which are connected to
the same IQ Bus can have the
same address.* Suppose, for
example, an IQ System has two IQ
Bus loops, 1 and 2, and this IQ-
PIP-USP2/CN is to be installed into
loop 1 and given an address of 77.
No other IQ
PIP s can be given the
same address in loop 1. However,
an IQ
PIP in loop 2 can have the
same address.
Different IQ components in the
same IQ Bus loop can have the
same address. For example, both
an IQ–USM 810 mixer/processor
and an IQ-PIP-USP2/CN can use
address 77 in the same loop.
A valid IQ address is any number
from 1 to 250. Do not use a number
higher than 250 since they are

* Note: All IQ PIP modules ( IQ-P.I.P.-
DSP, IQ-P.I.P.-SMT, IQ-PIP-USP2, etc.)
are considered the same type, and so
may not share the same address on
the same IQ Bus.
