IT-30DSP
DESCRIPTION: The IT-30DSP
is
a programmable frequency shift keyed (FSK) tone transmitter
intended for the use
on
the transmitting end of a communication channel
in
supervisory control,
telemetry and data transmission applications. A transmitter/receiver combination may
be
used over
voice grade circuits including carrier, wire line, fiber optics, and microwave.
Each transmitter module
is
field programmable for a specific center frequency and frequency shift
(bandwidth/baud rate) via DIP switches. Operational modes inciude two frequency (2F) or three
frequency (3F) keying, carrier on/off (Request-To-Send, RTS) and when communicating with a
similarly equipped receiver, inverted keying and flasher (keying of both mark and space
simultaneously).
Utilizing state of the art design and crystal controlled Digital Signal Processing (DSP) techniques
provides for improved performance, flexibility, and reliability.
FEATURES:
• Voltage keying inputs provided
on,
each unit (optical keying optionai).
• Front paneilevei adjustment.

SHOCK: Potentially dangerous electrical shock can occur whenever working
on
this product.
Protective measures and safety procedures should
be
observed
at
ali
times.
THEORY
OF
OPERATION:
GENERAL: The unit generates
an
audio tone which changes frequency when the input
is
keyed. The keying inputs are referred
to
as
mark and space.
In
the two frequency mode,
the audio tone output
is
at a frequency plus or minus the shift (programmable)
of
the
programmed center frequency. Upon keying (applying a voltage), the transmitter changes
state to the opposite frequency.
In
a two frequency system, the center frequency
is
not
produced.
In
a three frequency unit the center frequency
is
normally generated when neither a
mark or space output
is
present. When the transmitter is keyedtothe space frequency the
receiver space output
is
activated and when the transmitteriskeyed to the mark frequency
the receiver mark output
is
activated. Only one keying input should
be
on
at a given time
unless the IT-30DSP and receiver are set to operate
in
flasher mode. The Flasher option
on
the IT-30DSP allows the unit to shift between mark and space frequencies rapidly when both
inputs are
keyed
simultaneously.
A third keying input
is
available which allows the audio tone output to
be
turned on/off.
The
RTS
(carrier on/off) input permits the transmitter to
be
usedinsystems requiring a quiet
line until communications
is
need such
as
a polling or data system.
PROGRAMMING: Upon applying power to the unit, the Digital Signal Processor (DSP) (U5)
reviews the program information
of
octal inverting buffers(U12
& U
13)
which have been set
by switches
SW1
and SW2.
INPUT: Standard inputs are via
02, 03,
OS
and associated circuitry. The input informationisfed
to
(U4) octal
bus
driver along with the mode of operation settings
of
SW3.
(US)
Stores the
information
in
memory (RAM).
DSP(Digital Signal Processing): The microprocessor
(US)
operating parameters are determined
by
the two EPROM's (2K x 8-bit) U6 &
U7.
Ali
sine wave generation and keying input information
is
then processed
in
(US)."',
WATCH
DOG TIMER: (U9)
is
a watch dog timer which recycles the microprocessor should its
software sequence fail to perform
as
required. The timer effectively restarts the program to eliminate
having to re-initiate power
up
of the module.
OUTPUT: The digital signal
is
processed through (U14) digital to analog converter and then passes
through a low pass filter consisting of L
1,
L2
and associated capacitors (C10 - C14) Iimiting the
signals to 4kHz. Variable resistor (R24) adjust the signal level which
is
amplified by operational
amplifier (U16). The signal
is
coupled to the line via transformer T1.

Tighten all connections and insure exposed wires do not touch each other or the chassis.
INITIAL STARTUP & LEVEL CHECKS:
FREQUENCY SELECTION: With the module removed from the chassis. Select the desired
bandwidth and center frequency from the enclosed charts. Refer to figure 2 for switch location.
EXAMPLE: For
an
85
baud channel at 1615
Hz
center frequency, set SW2 position 3 to "ON"
(only a single position within SW2
is
to be "ON"
at
any one time). Set
SW1
positions
1,
4,
& 7
to "ON" (be sure
all
other positions
on
SW1
are "OFF").
MODE OF OPERATION: Set SW3 to the desired mode of operation
as
detailed below. Refer to
figure 2 for switch location.
SWITCH SW3 SETTINGS:
Ali Positions "OFF": 3F Operation. Keying the Mark input produces a Mark frequency out,
keying the Space input provides a Space frequency
outo
The center frequency will
be
output
when the inputisidle.
Position 1 "ON" only: 3F Operation, Inverted Output. Keying the Mark input produces a Space
frequency out, keying the Space input produces a Mark frequency
outo
The center frequency
will
be
output when the inputisidle.
Position 2 "ON" only: 2F Operation. Keying the Mark input produces the Mark frequency when
keyed. The Space frequency
is
output when the inputisidle. The keying leads should
be
on
the Mark input.
00
not use this option with position 3inthe "ON" position.
Position 3 "ON" only: 3F Operation, FLASHER. The transmitter will shift at 20msec intervals
between Mark and Space when the Mark and Space inputs are keyed at the same time. (This
operation will not function if the position 2
isinthe "ON" position).
Position 4 "ON" only: (RTS). When position 4
is
on,
the front panel switchisactivated. When
position 4
isinthe off position, the front panel switch will not
be
able
to
turn off the output(s).
RTS
can also
be
keyed from the
RTS
input
on
the rear terminai block when the front panel
switch (SW4)
is
in
the "OFF" position. This option may
be
used
in
all modes.
Positions 1
& 2 "ON": 2F operation, Inverted Output. Keying the Mark input produces a Space
frequency output. The Mark frequency
is
output when the inputisidle. The keying leads should
be
on
the Mark input.
00
not use this option with position 3inthe "ON" position.
ADJUSTMENTS: The transmitter contains a front panel LEVEL adjustment (R24) (see figure 2 for
location). Each transmitter
is
shipped from the factory with the level adjustment set at
-6
dBm,
which
is
adequate for most applications.
The following equipment
is
recommended to perform the initial startup
and
level
checks
at:
1.
Digital multimeter with dB readout function; Fluke 8060A or equivalent.
2.
Flatblade screw driver with 1/8 inch wide tip or potentiometer adjustment too!.
3.
Optionai - Card Extender.
WARNING:
00
NOT INSERT THE UNIT INTO A RACK WITH THE POWER ON.
INITIAL SETTINGS: With the power (+12Vdc) and phone line wired to the terminai blocks
on
the
rear of the chassis, connect the test leads of the multimeter (dB mode) across the "tone out"
on
the terminai block.
Turn
on
the power and note the reading
on
the multimeter (the tone output
on
the terminai block should
be
connected to the line or if this
is
not possible, terminated
in
a
600 ohm resistor). Adjust R24(LVL ADJ) with a screwdriver or adjustment tool to the desired level.
Only one transmitter should be
on
the line during this adjustment or a composite level will
be
read, which
is
not a true reading of the transmitter output level. The "as set" level should
be
recorded for future reference.
When two or more transmitters are connected on one communications line, each individual
transmitter level should be adjusted at a reduced level
in
order for the combined (composite)
signals not to exceed the desired output level. Refer to the chart below for recommended levels
referenced to 0 dBm. The recommended dBm levels may also
be
used as reference for any
desired level setting
in
dB.
