GENERAL DESCRIPTION


The Model 8200 FULL DUPLEX INTERCONNECT by Connect Systems Inc.
is a sophisticated repeater controller with built-in semi or full
duplex radio-telephone interconnect terminal. A built-in keyboard
and digital display allow the user to obtain the maximum power
from the on board microprocessor. All features are user
programmable and/or selectable. There are six modes of operation
to choose from...



1. Full or Semi-Duplex Base Station Interconnect
Adds interconnect to any duplex base station.

2. Full or Semi-Duplex Repeater Interconnect
Adds interconnect to any existing repeater system. Optional
ANI validation allows shared use and includes deadbeat
disable.

3. Repeater Controller with Duplex Interconnect
Converts any receiver and transmitter into a full featured
repeater.

4. Dial Access Remote Base
Dispatch and have full use of your radio system from any
telephone. Operates in any mode selected above.

5. Dial Access Paging Terminal
Beep Pagers and/or selectively call mobiles with or without
two way voice from any telephone.

6. Talk-Back Paging Terminal
Beep pagers or mobiles followed with a one way voice message
from any telephone.


And, powerful built-in standard features such as... 90 number
speed dialer, last number redial, remote hook-flash, remotely
controllable relay, automatic disconnect on busy signals and
dialtone, fully regenerated tone or pulse dialing, etc. make the
8200 the most powerful repeater controller/full duplex
interconnect product available today! Connect Systems Inc. - Model 8200 Page 4



Made and designed in the U.S.A.








INSTALLATION AND ADJUSTMENTS

The 8200 contains both a noise squelch and COS circuits with COS
input. This gives the 8200 a great deal of interface flexibility.
The audio takeoff point can be anywhere from the discriminator
(pre-emphasized audio) to the volume control (de-emphasized or
flat audio). If connection is made to the discriminator, only
three connections are required to most radios. When connecting
past the discriminator, a fourth COS connection must be made. Use
shielded wires with the shields at both ends connected to chassis
ground. (The rear panel barrier strip terminals labelled "GND"
are chassis ground). We recommend using spade type crimp-on
connectors for ease and reliability. Connect the center wires as
follows:

AUDIO IN: The audio input terminal may be connected directly to
the discriminator output, or to the high end of the
volume control.

If connecting to the discriminator...
1. A COS connection to the receiver is not
required.
2. The de-emphasis strap JP-5 must not be cut.
3. The COS polarity strap JP-1 must not be
strapped.
4. The noise control P2 must be adjusted to
illuminate the front panel noise LED. See "P2
NOISE" below for further explanation.

If connecting to the volume control high side...
1. A COS connection must be made.
2. Cut JP-5 to eliminate built-in de-emphasis.
3. JP-1 must be strapped for the appropriate COS
polarity.
4. The noise control must be set at minimum.
(fully CCW).
5. The COS threshold control P7 must be set to
match the level of the COS takeoff point.
Connect Systems Inc. - Model 8200 Page 5

See the appropriate sections below for detailed
directions.

COS:
NOTE: The COS input is normally not used if the AUDIO
IN is connected directly to the discriminator.

The COS input can be connected to the noise squelch
for carrier operation, or to the DPL/CTCSS squelch if
you want the radios' built-in decoder to provide
private operation.

Noise Squelch Connection: Connect to a point that
has considerable voltage swing when the squelch is
opened/closed. The best point to connect is to the
collector of the transistor that controls the busy
light (if the radio has one). Otherwise, connect to
the output of the noise rectifier.

DPL/CTCSS Squelch: The receiver's DPL or CTCSS
decoder will have a logic output that goes high or
low when a properly encoded signal is received.
Connect this point to the COS input.

If the point selected goes more positive (voltage
increases) when a signal is received, strap JP-1
center to the + side. If the point goes to a lower
voltage, strap JP-1 from center to the - side.

When the COS threshold control P7 has been properly
adjusted (described below), and JP-1 properly
strapped, the front panel noise LED will go out when
a signal is received. This condition must be achieved
for proper operation of the interconnect.

AUDIO OUT: Connect to the Mic high line. If Mic loading occurs
install a resistor in series with the Audio Out lead,
and cut JP-3. The resistor should be large enough to
prevent Mic loading but small enough to achieve
adequate land to mobile audio. Try 100K as a first
cut.

PTT: Connect to the transmitter PTT line.

NOTE: Some radios will need the Aux. Relay connected
to the hookswitch before the transmitter can be
activated. Others may require positive keying. See
'Auxiliary Relay' page 33 for details.

TONE The TONE output is used to inject signaling tones
separately from the voice audio and is normally only Connect Systems Inc. - Model 8200 Page 6

connected if options TSU-32P or 8203 are installed.
However options 8202 and 8204 can also use this
output if desired. Connect the TONE output past the
instantaneous deviation control (IDC) circuit in the
transmitter. Preferably directly to the modulator.

The 8200 can send the signalling tones from options
8202, 8203 or 8204 out the AUDIO OUT port or out the
TONE port. We recommend sending CTCSS audio from the
8203 out the TONE port, and signalling audio from the
8202 or 8204 out the AUDIO OUT port.

If you want signalling tones (from 8202, 8203 or,
8204) to go out the AUDIO OUT port, remove resistor
R-99.

If you prefer to inject these tones directly into the
modulator via the TONE port, remove resistor R-48
instead.

If the TSU-32P option is not installed and you want
your signalling tones to come out the AUDIO OUT port,
there is no need to remove R-48 or R-99.

R-48 is near the Tone Signalling pot. R-99 is near IC
U-25.

POWER:
Connect to a source of 12-14 VDC that can supply up
to 300 MA. The 8200 is reverse polarity protected, so
a polarity mistake will not damage your 8200.


#################### WARNING ####################

The 8200 contains a power supply sensing circuit that
continuously monitors the input supply voltage. An instantaneous
drop below 10 VDC will cause a microcomputer reset. If the power
supply has poor regulation, erratic operation may result.

The purpose of the input voltage sensor is to protect the non-
volatile EE memory during power up and power down.

If erratic operation such as losing call
