board.
M. Analog Outputs
Four unbalanced analog outputs are pro-
vided. The output is taken from the corre-
sponding balanced inputs. The Drone pro-
vides 3.6 dB of gain from balanced input to
unbalanced output with the standard factory
gain set resistors installed.
N. Digital (Aux) Inputs
The Drone has 16 digital (Aux) inputs. These
inputs sense a logical high (on) or low (off)
condition. The Drone has two modes of op-
eration to handle the logic information sensed
at these inputs. The first is referred to as "sim-
plex." In simplex mode, the individual input
is directly associated with a specific group
of whatever logical system commands you
associate with it. The second mode is called
"binary." In the binary mode three or more
consecutive digital inputs are grouped to-
gether. The group functions like a parallel
port, looking for a binary number on the in-
puts (lowest input number is the LSB). A com-
mand set group is associated with each bi-
nary number. The maximum number of com-
binations, hence maximum number of unique
command groups, depends on how many
digital inputs are grouped together in a bi-
nary channel. The last member of a binary
channel is a strobe. For example, if you want
a 16 bit input, you need four consecutive digi-
tal inputs in binary mode with a fifth input as
a strobe. When a binary number from 0 to 15
is sensed, send a logical high to the strobe
and the Drone will engage whatever system
commands are associated with the binary
number you provided.
O. Digital (Aux) Outputs
In addition to 16 logic inputs, the Drone also
has 16 logical outputs. These outputs can
drive a logical input or other device when
switched on. The Drone can be programmed
to provide a logical output based on almost
any type information provided by the Drone
or other system component. Output drive is
a maximum of +15V at 15 ma.
P. Ground Strips
A series of ground strips are provided for
plenty of ground reference connections to
external devices such as pots, relays, LEDs,
or other devices.
Transponder Mode
To use multiple Drones in a system requires
that each Drone operate with Transponder
Mode on. In this mode each Drone may only
directly control components connected to its
own Loop 2 Crown Bus. Drones are intercon-
nected using the Loop 1 connection on each
Drone. In software the loop interconnecting
the Drones becomes Loop 251 and the local
loop on each individual Drone takes a loop
number which is the same as that Drone's
address. This mode of operation allows a
system to have up to 251 loops (one master
Drone loop and a transponder loop per Drone
with a maximum of 250 Drones). Note: Turbo
1.3 or higher is required to support Drone
V1.1 firmware with Transponder Mode capa-
bility.
Training The Drone
There are two main ways to program a Drone.
Both require IQ-MSD Turbo 1.2 (or higher)
software for IBM compatible PCs. The Drone,
like the SMX-6
™
Mixer, has sub-block screens
where analog and digital input commands are
programmed. Turbo software also has spe-
cial objects for the Drone that allow you to
program the Drone using simple screen ob-
jects and a mouse. Once programmed, the
computer may remain if desired, or may be
completely removed for total stand alone
automatic operation.
Drone Intelligence (Version 1.1)
As of November 1995 Drone V1.11 is avail-
able, replacing the original V1.0 firmware. The
new firmware supports all function and fea-
tures of the first version with several valuable
additions. The Drone now supports opera-
tion as an interface for U-Code products such
as the Crown PIP-DP, White Instruments 5000
Series IQ DSP products, and t.c. electronics
EQ for IQ. The new Drone firmware also sup-
ports multiple Drone system architecture with
Transponder Mode. Other operational areas
are also improved including expansion of
paralyze capabilities.
The Drone has another function as yet not
discussed, called the paralyze command.
The paralyze command allows a digital input
(simplex mode only) to paralyze other inputs
on demand. This level of operation allows one
input to lock out another for security or other
purposes.

release, contact the Crown Technical Sup-

Additional Electrical Specifications
Dimensions: 3.75 inches (9.52 cm) wide for 3-
space IQ-CAG mounting; 7 inches (17.78 cm)
high, and 12.125 inches (30.8 cm) behind
mounting surface.
Power Supply: +10 to +15 VDC, +12VDC nomi-
nal. Internal battery soldered to the module
provides backup for power loss up to 30
days; charges when Drone is powered. In-
ternally the Drone produces several voltages
including +15 VDC for digital output drive,
and +10 VDC for use by external control de-
vices.
Display: Power LED shows presence of +12
VDC supply, DSPI LED shows reception of
digital information addressed to the unit.
Controls: An 8 segment DIP switch on the com-
ponent face of the circuit board is used to
set the IQ Address. A 4 segment DIP switch
sets the RS232/422 baud rate. Jumpers on
the module face are factory set to configure
memory. Resistors and capacitors mounted
on the T-board are used to set analog input
gain and phantom power.
Serial Port: A female DB9 serial port is pro-
vided to accept either RS232 or RS422 for
direct communication with a computer. Ra-
dio Shack 26-117 standard RS232 cable is
recommended for PCs.
Crown Bus: Two Crown Bus serial data loops
can be used via an 8 pin mini-barrier strip.
Analog Inputs: 16 analog inputs are provided
which can accept DC, AC, or audio for sys-
tem control and command functions. Inputs
1 through 4 are balanced. Phantom power is
optional, sensitivity is changeable. Inputs 5
through 16 are unbalanced, sensitivity is
changeable. Sensitivity is factory set to 10
VDC/7.07 VAC/+19.2 dBu. Frequency re-
sponse of all inputs is DC to 20 kHz (+0/–1
dB); with phantom enabled 16 to 20 kHz (+0/
–3 dB). Common mode rejection better than
–40 dB (balanced inputs). Input impedance
is 69 Kohms.
Phantom Power: +10V, requires installation of
resistors and clipping out electrical shorts
across input coupling capacitors.

plex or binary input to logic command sets.

from 0V to +5V input; 20 Kohm above or be-
low this range.
