PURPOSE
The CS-700 provides everything necessary to interface any FM transceiver
to the telephone network. Once connected to the base radio, mobile and
portable radios can initiate and receive phone calls fully automatically
when in range of the base station.
The CS-700 is the only interconnect available that gives the user a
choice of VOX Enhanced or VOX Controlled Sampling. Each choice offers
distinctly unique advantages. Each method is microcomputer controlled
and uses an advanced telephone VOX as a control reference.
No other low cost interconnect provides advanced high tech features such
as Autodialing, Redial, Hookflash, User programmable CW ID, Fully
regenerated DTMF dialing, Automatic sample set-up, Built-in programming
keyboard and display etc. etc.

INSTALLATION AND ADJUSTMENTS
The CS-700 requires only three connections to most radios. Use
shielded wires with the shields at each end 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: Connect directly to the discriminator output. Be sure to
connect before the de-emphasis network.
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-1.
The resistor should be large enough (try 10k) to prevent Mic
loading but small enough to achieve adequate land to mobile
audio.
PTT: Connect to the transceiver PTT line.
POWER: Connect to a source of 12-14 VDC that can supply up to 300 MA.
The CS-700 is reverse polarity protected, so a polarity
mistake will not damage your CS-700.
ADJUSTMENTS
Initial settings: Set P1, and P2, fully counterclockwise.
Set P3, P5 and P10 to mid rotation.
POT PCB Name Function
P1 M->L: Mobile to land level: Initially adjust until mobile
DTMF decodes as indicated on front panel DTMF LED.
Later, adjust for proper mobile level as heard on
telephone.
P2 NOISE: Noise (squelch) control: Advance clockwise to a
point just_beyond where the front panel noise LED
lights without any flickering.
Note: The noise LED must_be_operating but will only
light if 'Audio In' is properly connected to the
discriminator output. No other point will work!
P3 TEL VOX: Telephone VOX Sensitivity: Both VOX enhanced and VOX
controlled sampling depend on the VOX adjustment for
land line audio sensitivity. Clockwise rotation
increases the sensitivity. For most applications mid
rotation should be about right.
P5 BEEPS/CW ID: Status beeps & CW ID level: Adjust for desired
modulation level of status beeps or CW ID.

Connect Systems Inc. - Model CS-700 Page
4
P10 L->M: Land to mobile level: Press the C/D
(Connect/Disconnect) switch so that a dialtone is
heard. Adjust P10 until the dialtone produces about
3-4 Khz. of modulation deviation. Cut JP-1 if
required.
JP-1 Audio output range strap. Strap in = (0-1V), out = (0-5V).
PROGRAMMING THE CS-700
The CS-700 has three easy-access programming areas: Operating
Parameters, CW ID and Auto-Dial Phone Numbers. To enter one of the
programming areas, turn the power off, press and hold the corresponding
programming area button (No. 1 for Operating Parameters, No. 2 for CW ID
or No. 3 for Auto-Dial Phone Numbers) and simultaneously turn on the
power. The display will show 0.x., where x is the number of the
programming button that is being pressed. Release the button, and
programming may begin.
Each programming area has the following features in common:
1) Programming line numbers are displayed with the dots illuminated
on the displays. e.g. 0.1., 2.5. etc.
2) Data values are displayed without the dots illuminated. e.g. 00,
30, etc.
3) Data is entered at a line number by pressing the desired digits
followed by the 'P' key. Consider the 'P' key as the enter key.
4) The GOTO Any Address line is displayed as A.A. This line is used
to branch to any line number in the current programming area.
For example, the current line is A.A. and you wish to goto line
25. Enter 2 5 P on the keypad and the display will read 2.5.
5) Pressing only Pat the A.A. line will advance the line to 0.1.
Pressing only Pat any other line will advance to the next
available programming line. NOTE: In CW ID and Auto-Dial Phone
Number programming, the next line will be the next numeric line
number. In Operating Parameters programming the next line is not
necessarily the next numeric line (see the 'Programming the
Operating Mode and Parameters' section).
6) To view the data at a given line number, briefly press Con the
keypad and then release it. The display will then show the data
for a few seconds and then re-display the current line number.
Consider 'C' the data 'see' key.
7) At any point during programming, you may return to the A.A. line
by holding down the Ckey until A.A. appears on the display
(approximately three seconds).

PROGRAMMING THE OPERATING MODE AND PARAMETERS
(Programming area No. 1)
To enter the parameter programming mode, press and hold button No. 1 on
the internal keypad and then simultaneously turn on the power switch. At
this point, the display will read 0.1. When you release the No. 1
button, you will see A.A.
A.A. (GOTO Any Address)
Press 'P' to start at line 0.1., or enter the line number you wish
to go to and then press 'P'. All line numbers and their associated
parameters are listed below starting with OPERATING MODE.
Viewing or Changing Parameter Values
A quick tap on 'C' will reveal (for a moment) the currently
selected parameter of the displayed program line. If the
parameter is acceptable, press 'P' to advance to the next
program line, or, enter a new parameter and press 'P' to
advance to the next program line.
Parameter Checking
If an out of range parameter is entered (eg. 87 on line
0.3.) pressing 'P' will not cause an advance to the next
program line. This prevents you from accidentally entering
an unuseable choice.
Returning to A.A.
Programming is finished when you arrive back at A.A. If
necessary, you can return to a previously programmed line by
holding down 'C' for several seconds. This will return you
to A.A. Now enter the line number you wish to return to and
press 'P'. Line sequential programming will always flow
forward from the current line.
Line numbers shown in braces e.g. [0.3.] indicates where
programming will continue after a selection.
When you finish programming, simply turn the power off, and back on
to return to the operate mode.
OPERATING MODE [Branch to]
0.1. Operating Mode
0 = VOX Enhanced Sampling [0.2.]
1 = VOX Controlled Sampling [0.3.]
DEFAULT: 1 = Vox Controlled Sampling
VOX Enhanced Sampling: The sampling rate is reduced by a factor
selected on line 0.2. while the telephone party is talking. This
allows the mobile to maintain full control.
VOX Controlled Sampling: Sampling stops completely while the land
party is speaking. In fact, sampling will never be heard if the

Connect Systems Inc. - Model CS-700 Page

mobile presses the mic. button immediately upon hearing the turn-
around beep.
0.2. VOX Enhanced Sampling Factor
Select 1-9
DEFAULT: 3 = 3:1
The VOX enhancement ratio can be varied from 1 to 9. One is
equivalent to no enhancement. Nine is maximum enhancement. Pick the
enhancement ratio that slows the sample rate the desired amount
while the telephone party is speaking.
0.3. Sample Width
Select 1-85 (3-255 ms)
Enter 0 for automatic set-up
3 ms increments per step
DEFAULT: 85 = 255 ms (milliseconds)
Optimum performance will occur when the sample width is made as
small as your radio will tolerate. The sample width may be set
manually or with the built-in automatic set-up feature.
The sample width can only be adjusted if the CS-700 is properly
connected to your radio, and the noise light is illuminated.
Note: The display will flash on and off if the noise light is not
working or adjusted properly. You can not proceed until the
noise light is illuminated. See page 3, "P2 noise:".
Automatic Set-up: Press 0 P (zero then P). This starts the auto
set-up procedure. Then press the Mic button on your mobile or
portable radio. The noise light should go out. Then hold the # key
on the radios' touch pad until the auto-set sample width is
displayed on the digital display. Your CS-700 should now be ready
to use. In rare cases it may be necessary to manually fine tune the
sampling width for best results.
Manual Set-up: Check to see if the mobile can seize control. Remove
the phone cord and press the front panel C/D pushbutton. The C/D
LED should illuminate and the XMT LED should periodically flash off
indicating sampling. The mobile is able to seize control if the XMT
LED goes out when the mobile transmits.
Go back into program mode and reduce the sample width a little at a
time. Each time checking to see if the mobile can still seize
control. The final setting should be 10 - 20 percent higher than
the point where mobile control was lost.

0.4. Sample Rate
Select 1-9 (.25-2.25 seconds)
.25 sec increments per step
DEFAULT: 3 = .75 sec
Select a sample rate to suit your preference. One sample each .75
second is a good starting point. The sample rate in seconds is
equal to .25 seconds times the number you enter.
OUTGOING CALLS
0.5. Line in Use Detect
1 = Enable
0 = Disable
DEFAULT: 1 = Enable
When enabled, mobiles are prevented from cutting in on calls that
are already in progress on the same line. A special busy tone lets
the mobile know that the line is in use. At the same time beeps let
the telephone user know that a mobile unit would like to use the
line. Upon hanging up, a set of beeps lets the mobile know that the
line is now free to make a call. (Call waiting feature).
0.6. Connect Code
0 = * Up
x - xxxx = Multi Digit Access
Protocol: *xxxx
DEFAULT: 0 = * up
Selects the phone patch access code. Enter 0 for * up operation.
Otherwise enter a one to four digit code. To access the patch press
* plus the selected code. For example: Enter 89 if you want the
access code to be *89.
0.7. Secret Toll Override Code
x - xxxx = Multi Digit Override
Protocol: *xxxx
DEFAULT: 1234
A separate secret code that overrides the programmed toll
protection. The access code (0.6.), and the secret toll override
code cannot start with the same sequence. e.g. An access code of *2
would not be compatible with a secret code of *2567. Select codes
that are distinctly different. Such as access code = *56 and secret
code = *3927.
NOTE: The secret Toll Override Code is inoperable if * up is
selected on 0.6. At least one additional digit must be programmed.

Viewing or Changing Phone Numbers
A quick tap on 'C' will reveal the currently selected phone number
for the displayed autodial location. The phone number is displayed
digit by digit until all digits in the number have been shown. If
the phone number is acceptable, press 'P' to advance to the next
location, or, enter a new phone number and press 'P' to advance to
the next location.
NOTE: If there is no number at the current location, pressing 'C'
will flash the current location number once instead of showing a
phone number.
Programming *, Pause or #
The No. 1, 2 and 3 keys on the keypad are used as dual input keys.
To program a phone number which contains any of these digits,
briefly press the key and continue with the number, as you would
with any other digit. To program a *, press the No. 1 key until a
single bar '| ' is added to the display (approx. 3 seconds) then
release the key. To program a pause, press the No. 2 key until a
dash ' -' is added to the display. To program a #, hold down the
No. 3 key until a double bar '||' is added to the display.
NOTES: 1. A single bar '| ' will look like the digit one ' |', except
that the single bar is shifted to the left a little.
2. Autodial memory locations can be overwritten with new phone
numbers, or cleared by entering three zeros (000P).
3. A maximum of 16 digits may be entered in autodial locations 1
through 9.
Returning to A.A.
If desired, you can return to a previously programmed auto-dial
location by holding down 'C' for several seconds until A.A. shows
on the display. Now enter the autodial location you wish to return
to and press 'P'.
Returning to Operate
To return to normal operation, switch off the power and then back
on. You can now use your newly programmed autodial numbers!

OPERATION
NOTE: The DTMF digits * and # are shown on the internal display as a
'| ' and '||' respectively (same as 'p' and 'c'on the internal
keypad). This is because the displays used can not display the * and #
symbols.
PLACING OUTGOING CALLS
DIALING A CALL MANUALLY: From the mobile press *, then enter the access
code (if any) that was selected on line 0.6. or, enter the secret toll
override access code that was set on line 0.7. If the access delay on
line 1.0. is properly set, you will hear dialtone or CW ID start without
clipping or delay. Wait until the dialtone drops off before you start to
dial.
After dialing, the next thing heard will either be ringing or a busy
signal. The CS-700 will automatically disconnect if the number that was
called is busy. (2.0. 2.1.).
LINE IN USE DETECTION: If line in use detection has been enabled,
(0.5.), the CS-700 checks to see if the line is in use when a mobile
attempts access. If the line is free the mobile will hear dialtone and
he can proceed with his call. If the line was in use, the CS-700 will
send a special busy signal to the mobile and revert to the stand-by
condition. At the same time, Call Waiting beeps let those using the line
know that a mobile unit would like to use the line. When the telephone
users hang-up, beeps let the mobile know that the line is now free to
use.
The mobile can cut-in on the call if desired by using the secret toll
override code (0.7.) after hearing the line in use busy signal. A three
way conversation can now take place.
PROGRAMMING THE AUTODIALER FROM THE MOBILE: Writing a phone number into
the autodialer memory from the mobile is accomplished with a slight
variation on ordinary manual dialing. Before you enter your access code,
send 9 followed by the desired memory location number. e.g. You wish to
place a call to 277-1463 and simultaneously add the number to autodial
memory location 6. From the mobile, enter 9 6 then the access code. When
the dialtone is heard, dial 277-1463 just as you would in ordinary
manual dialing. You will never have to manually dial 277-1463 again!
Note: The 9 as used above means WRITE the phone number that is to be
dialed into the memory location specified immediately following the 9.
You can program a *, pause or # as part of an autodial sequence if
desired. The digits 1,2 and 3 are interpreted as *, pause and # if held
down for 4-5 seconds during the dialing process. For example: you wish
to program; 8 pause 472-8197 into memory location No. 3. Enter in order;
9 3 then your access code. Then after dialtone enter 8, long 2, 472-
8197. The number you have dialed is now properly loaded into memory

Connect Systems Inc. - Model CS-700 Page
15
location No. 3. However the long 2 will cause a misdial of the immediate
call. When a *, pause or # has been used, do not let the call go
through. Send the disconnect command after the number has been dialed
and call back using the autodialer. The call will now dial properly.
PLACING A CALL WITH THE AUTODIALER: Once a phone number has been stored,
calling back is a snap! Simply preceed the access code with the
appropriate memory location number. Soon, your intended number will be
ringing. Example: Your access code has been set as * only. You wish to
call a friend whose phone number has been previously stored in location
6. Simply enter 6 * on your mobile keypad. Another example: Your access
code is *391, and you wish to autodial the number in memory location No.
7. Enter 7*391, thats all there is to it!
NOTE: If you attempt to autodial from a memory location that has not
been previously loaded, the CS-700 will send an error message
consisting of a string of beeps, and then return to the stand-by
condition.
LAST NUMBER REDIAL: The last phone number called is always automatically
stored at autodial memory location NO. 0. To redial the last number
called, simply preceed the access code (0.6.) with 0. Similar to using
the autodialer. e.g. 0*, 0*391 etc.
HOOK FLASH: The CS-700 has built-in hook flash logic to operate certain
phone company provided features such as call waiting. To flash, simply
press * three times (***).
Note: Using hook flash can cause a disconnect on some phone lines.
ACTIVITY TIMER: The activity timer measures how long its been since the
last mobile transmission. If the time set on line 1.7. is exceeded, the
CS-700 will disconnect. A short warning is emmited once per sample
during the final 10 seconds. Pressing the Mic. button will reset the
activity timer.
Note: Normal speed sampling will occur during the final 10 seconds to
facilitate mobile reset if desired.
TIMEOUT TIMER: Calls will automatically disconnect at the end of the
time you selected on line 1.8. Two quick beeps heard during each sample
cycle in the final 30 seconds warn that timeout is imminent.
Note: Normal speed sampling will resume during the final 30 seconds to
facilitate mobile reset if desired. To reset the activity timer, the
mobile simply presses the mic. button and sends *.
DISCONNECTING WHEN THROUGH: If a "0" was entered on line 0.8. simply
press # to disconnect. If a "1" was entered, press # plus the connect
digits that were selected on line 0.6.

Connect Systems Inc. - Model CS-700 Page

RECEIVING INCOMING CALLS
RINGOUT: Lines 2.4. through 2.7. allow you to customize ringout for your
application. Ringout is how the CS-700 alerts you to the presence of an
incoming call.
When a call comes in, the CS-700 first checks to see if the channel is
in use (2.4.). The incoming rings are counted (2.5.) before a mobile
alert is sent. The alert can consist of CW ID, or a ring tone (2.6.).
The type of alert selected can be set to occur only once or on alternate
rings (2.7.) of the incoming call.
To answer your call from the mobile, simply enter your access code
(0.6.). When you complete your call, send the disconnect code (0.8).
CALL PROGRESS TONE DETECTION
The CS-700 incorporates very sophisticated software algorithms that
automatically sense the presence of dialtone and/or busy signals. The
method used will function with any tone frequencies. There is nothing to
adjust or maintain, it's completely automatic!
Busy signal disconnect will automatically cause a disconnect if the
number you call is busy. Thus relieving the mobile of pressing # to
disconnect.
Dialtone disconnect is useful on exchanges that automatically return to
dialtone when your called party hangs up. Again, relieving the mobile of
pressing # to disconnect.
Programming lines 2.0. and 2.1. give the user independent control of
disconnecting automatically on busy signals and dialtone.

TYPICAL APPLICATIONS FOR THE AUXILIARY RELAY
(Option 701)
Disabling_tone_squelch: Many of the new microprocessor controlled radios
will not transmit when the microphone is on hook. The auxiliary relay
can be used to fool the radio into thinking the MIC is off-hook.
Enter 0 (Connect) on line 2.2. This will energize the relay whenever the
CS-700 is in use. Connect the normally closed contacts (W and NC) in
series with the radios' hook switch.
Key_System_Compatability: In order to simulate a keyset phone, the A
Leads (black and yellow) must be shorted whenever the CS-700 is in use
(connected).
Enter 0 (Connect) on line 2.2. Connect the two "KEYSYS" pads (adjacent
to the modular phone jack) to NO and W respectively.
Relay_Switched_PTT: If the radios'unkeyed PTT voltage exceeds 16 VDC or
if inverted keying is required (closure to 12V) the auxiliary relay must
be used to key the transmitter.
Enter 1 (KEY) on line 2.2. Connect the radios' PTT line to Aux. relay W.
For sink to ground keying connect N.O. to GND. For pull to 12 VDC keying
connect N.O. to 12 VDC.
Remote_Relay_Function: In some installations it may be desireable to
remotely control (switch) something from the mobile. e.g. change
channels, change antennas etc.
Enter 2 (REMOTE FUNCTION) on line 2.2. Then select a three digit control
code on line 2.3. If the code selected was 789, you would turn on the
Remote Relay by sending #789. To turn off the relay send ##789.
Connect the device requiring remote control to the AUX. RELAY W and N.O.
or N.C. as required.
Installation: Insert the relay (Potter Brumfield part No. JWD 107-3 or
equivalent) into the empty IC socket labelled 'Aux. Relay'. Be sure to
orient the cutout end toward the key board. The relay contacts are
available on the rear panel barrier terminal block.
How to order: Send check, bank check or money order for $7.00 ($9.00 if
outside the U.S.A.) made payable to Connect Systems Inc. Please remit to
the address shown on the front cover of this manual. Specify part No.
701. Your relay will be shipped postpaid.

TELEPHONE COUPLER
(Option 702 - no longer available)
U.S.A. customers wishing to make direct connection to the public
switched telephone system must use an FCC approved telephone coupler. A
coupler is not required on private phone systems.
You can either use your own coupler, or the popular Morey coupler.
When requesting a line, the following information must be given the
phone company: FCC registration: AB3985-62455-PC-E
Ringer equivalence No. 0.4A, 1.0B
You must notify the phone company when discontinuing use. Also,
connection to coin or party lines is prohibited.
Installation: Remove the CS-700 PC board and solder the six position
terminal block to the PC board. Connect the six leads per illustration
below.
If your interconnect uses the Morey coupler, do not plug anything into
the rear panel modular phone jack. Use the phone cord which exits from
the coupler.

LIMITED WARRANTY
We guarantee the Model CS-700 to be free from defects in material and
workmanship for one year from purchase. Tampering, misuse or
modification shall void this agreement.
Several components in the CS-700 are mounted in sockets. We reserve the
right to not cover these parts under warranty if failure is traceable to
removal/re-insertion.
The PTT transistor (Q19) is not covered under warranty. Failure can only
be caused by incorrect connection of the PTT output to the radio.
Usually to a hard voltage such as 12 VDC.
The quality of components used in the CS-700 is excellent. It should
give many years of trouble-free service. Should it fail, we shall repair
it at our factory, and return it to you within one day if possible.
We reserve the right to not repair units which have been "modified".
This warranty does not cover damage caused by external overloads such as
lightning or power source surges. Further, the warranty does not cover
damage caused by any act of GOD.
The CS-700 utilizes two metal oxide varistors connected from phone line
to ground. These "MOV's" should protect the CS-700 from all but the most
severe lightning strikes. However, we reserve the right to not repair a
unit which in our opinion is too extensively damaged. Further the
warranty of a unit which has been hit by lightning is terminated. This
is because of latent damage which can surface at a future date.
Should repair become necessary, please send a copy of your sales invoice
together with the interconnect.
