Before beginning, please carefully
note:
CAUTION: STATIC ELECTRICITY
MAY DAMAGE THE IQ-PIP-USP2
MODULE. Use caution when han-
dling the unit. Carefully ground your-
self BEFORE touching the IQ-PIP-
USP2 module. Avoid unnecessarily
touching the components or solder
pads on the circuit boards.
3.1 Prepare the IQ-PIP-
USP2
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 Crown 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 6.
The tables show the switch
settings for all 250 addresses.
No two IQ components of the
same type which are connected to
the same Crown Bus can have the
same address.* Suppose, for
example, an IQ System has two
Crown Bus loops, 1 and 2, and this
IQ-PIP-USP2 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 Crown Bus loop can have
the same address. For example,
both an IQ–USM 810 mixer/
processor and an IQ-PIP-USP2
can use address 77 in the same
loop.

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