DESCRIPTION: The IT-30DSP
is aprogrammable frequency shift keyed (FSK) tone transmitter
intended for the use
on the transmitting end of acommunication channel in supervisory control,
telemetry and data transmission applications. Atransmitter/receiver combination may
be used over
voice grade circuits including carrier, wire line, fiber optics, and microwave.
Each transmitter module
is field programmable for aspecific 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.

Standard safety precautions must be followed at all times when installing, operating,
servicing, and repairing this.)equipment. INIVEN/CONOLOG
CORP. assumes no liability
for failure to observe standard or specifically noted safety requirements or to use this
equipment for purposes other than intended.
GROUNDING: Asuitable ground
is required to reduce the hazard of shock. Refer to the
enclosed module, chassis, and/or cabinet 'wiring diagram for ground connection locations.
ENVIRONMENT: Operation of any electrical equipment
in any area containing gases, fumes,
wet, or damp
is apotential safety hazard. Necessary precautions should be taken.
MANUAL: Operators and maintenance personnel should read this manual before installing
the equipment and placing it
in service. Only properly trained personnel with proper tools and
equipment should operate, maintain, repair, or service this equipment.
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 afrequency plus or minus the shift (programmable) of the
programmed center frequency. Upon keying (applying avoltage), the transmitter changes
state to the opposite frequency.
In atwo frequency system, the center frequency is not
produced.
In athree frequency unit the center frequency is normally generated when neither a
mark or space output
is present. When the transmitter is keyed to the space frequency the
receiver space output
is activated and when the transmitter is keyed to the mark frequency
the receiver mark output
is activated. Only one keying input should be on at agiven 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.
Athird 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 used in systems requiring aquiet
line until communications
is need such as apolling or data system.
PROGRAMMING: Upon applying power to the unit, the Digital Signal Processor (DSP) (U5)
reviews the program information
of octal inverting buffers (U 12 &U 13) which have been set
by switches
SW1 and SW2.

INPUT: Standard inputs are via 02, 03, OS and associated circuitry. The input information is fed
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 x8-bit) U6 & U7. Ali sine wave generation and keying input information
is then processed in (US)."',
WATCH DOG TIMER: (U9) is awatch 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 alow 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.

interconnected chassis, or as part of arack or cabinet. Follow the procedure for the type of system
supplied.
Loose and/or equipment mounted
in an individual chassis will be packed in its own shipping carton.
Inspect the carton for possible damage
in transit. Open each carton carefully and remove the
contents. Inspect the equipment for possible damage. Verify
ali items of value have been removed
prior to discarding any packing materia!.
NOTE: It is suggested the carton be retained for possible onward shipment.
Interconnected chassis or equipment supplied
in racks or cabinets will be supplied in special boxes,
wood crates, or if shipped via air-ride
van without any case. Inspect the crate or other packing for
possible damage
in transit. Carefully remove the equipment from the container and inspect it for
possible damage. Verify
ali items of value have been removed from the crate prior to discarding
any packing material and refer to the note above.
Should transit damage
be found please notify INIVEN immediately.
MOUNTING: After unpacking follow the appropriate mounting procedure.
Loose module: (The following
is for new installations -replacement of an existing module will have
the termi nai block already mounted. Each new unit is shipped with the terminai block plugged into
the rear of the unit. There are also four 6-32 screws shipped with
it to mount the terminai block to
the chassis. Locate the desired position within the chassis for which the module is to be placed.
Viewing the chassis from the front, the recommended arrangement
is apower supply on the extreme
left then followed
by transmit and or receive modules working towards the right of the chassis.

Interconnected Chassis or equipment mounted on shipping rails is to be mounted similar to an
individual chassis. When shipping rails are provided the equipment is to be placed near the desired
location. Remove the screws holding the shipping rails and then remove the rails. Slide the equipment
into the rack or cabinet and secure it with proper screws for the mating hardware being used.
Tighten ali screws.
Systems provided
in arack or cabinet from the factory must be secured to the floor or wall as
required. Mounting hardware is not sqpplied due to the various surfaces and mounting methods.
CAUTION: EQUIPMENT MOUNTED IN SWING RACK TYPE CABINETS MUST BE SECURED
TO THE MOUNTING SURFACE PRIOR TO OPENING THE SWING RACK TO PREVENT THE
CABINET FROM FALLlNG.
VENTILATION: Proper ventilation is required for most electronic equipment. Enclosed cabinets or
rooms where this equipment
is mounted should be kept at temperatures within the limits of the
equipment. Operation above these limits may affect reliability.
ELECTRICAL CONNECTIONS: User connections are made via the terminai blocks
on the rear of
the chassis. Each unit in the Gen 1SERIES of equipment will contain these connections in the
instruction manual for the specific individual module.
On equipment supplied wired from the factory
or
on wired chassis and cabinets an "as supplied" drawing will be included with the equipment.
External wiring should
be in accordance with the "as supplied" drawing when supplied.
For safety reasons power on the leads to be connected to the unit are to be de-energized
during installation.
Methods of making the wiring connections to the terminai blocks vary and based on local practice.
It is suggested number 20 AWG size insulated wire, stripped portion tinned, be used. Approximately
1/4" of the insulation
is to be removed and inserted in the terminai block.
Module power and tone lines may
be daisychained should the application require.
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 2for switch location.
EXAMPLE: For an 85 baud channel at 1615 Hz center frequency, set SW2 position 3to "ON"
(only asingle 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 2for switch location.

SWITCH SW3 SETTINGS:
Ali Positions "OFF": 3F Operation. Keying the Mark input produces aMark frequency out,
keying the Space input provides aSpace frequency
outo The center frequency will be output
when the input is idle.
Position 1"ON" only: 3F Operation, Inverted Output. Keying the Mark input produces aSpace
frequency out, keying the Space input produces aMark frequency
outo The center frequency
will
be output when the input is idle.
Position 2"ON" only: 2F Operation. Keying the Mark input produces the Mark frequency when
keyed. The Space frequency
is output when the input is idle. The keying leads should be on
the Mark input. 00 not use this option with position 3 in the "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
is in the "ON" position).
Position 4"ON" only: (RTS). When position 4
is on, the front panel switch is activated. When
position 4
is in the 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 aSpace
frequency output. The Mark frequency
is output when the input is idle. The keying leads should
be on the Mark input. 00 not use this option with position 3 in the "ON" position.
ADJUSTMENTS: The transmitter contains afront panel LEVEL adjustment (R24) (see figure 2for
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 ARACK 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 ascrewdriver or adjustment tool to the desired level.
Only one transmitter should be
on the line during this adjustment or acomposite level will be
read, which is not atrue 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 areduced 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 0dBm. The recommended dBm levels may also
be used as reference for any
desired level setting
in dB.
