INTRODUCTION
Congratulations on your purchase of the CD-2 communications decoder. You will
find enclosed with your new CD-2 a DB-9S RS-232 adapter and a 6 wire modular
cord. They are especially wired for the CD-2. The CD-2 is intended for the
communications professional or hobbyist who needs the finest test equipment in
order to properly monitor systems and service land mobile equipment.
This manual contains instructions for installation and operation of the CD-2,
CD-2-CAR, and the optional CD-2P application program. At the end is a brief
trouble shooting guide. As of version 1.04 of the CD-2 processor, the CD-2-CAR
personality may be owner selected by adding/cutting a jumper on the main PC
board. This jumper is located next to JP2 but is not labeled on the silk
screen. On the schematic, it is called JP5. If JP5 is installed, the CD-2 will
behave like a CD-2-CAR.
CD-2-CAR Operation
The CD-2-CAR decodes only DTMF. It's purpose is to display ANI codes. When a
DTMF character is received, it blanks the display and displays the character
at the right side. As more characters are received within a 1-2 second timeout,
they are scrolled from right to left. As long as not more characters are
received, the display remains illuminated with the decoded digits. The display
will extinguish after 25 seconds unless JP2 is installed. If JP2 is installed
the display will remain on indefinitely until a new DTMF character is detected.
In all other respects, the CD-2-CAR is exactly like the CD-2.
INSTALLING, ADJUSTING AND OPERATING YOUR CD-2
INSTALLATION
The CD-2 must be connected to a source of clean 10-15 VDC power and to the
receiver. For best results, please use shielded wire for power and receiver
connections.
GND: Power supply return (-) lead.
+12V: Positive side of the 10-15 VDC supply. If receiver is powered
with 12 VDC, share with CD-2.
GND: Shield of cable to receiver chassis ground.
INPUT: From receiver (see AUDIO TAKEOFF POINT below)
AUDIO TAKEOFF POINT
The CD-2 can be connected to a variety of places in the receiver depending upon
what you wish to decode.
To decode CTCSS, DCS and DTMF, the CD-2 must be connected directly to the
detector output (before de-emphasis). The De-Mod output on service monitors is
suitable. In many receivers connecting to the Center Meter test point or to a
TNC Packet output port may work satisfactorily.
If you only wish to decode CTCSS and DTMF, a connection to the high side of the
volume control may work. (CTCSS may not decode at this point depending upon how
the receiver is configured).
If you only care about decoding DTMF or you have a CD-2-CAR, a connection to
the speaker leads will probably suffice (amateur receivers and scanners may
even decode CTCSS at this point).

3
If in doubt about where your detector output is, simply contact a technical
representative at the company who produced your radio. Alternatively, send us
a schematic diagram, and we will attempt to assist you, however bear in mind
the manufacturer of your radio knows more specific details about your radio
than we do.
ADJUSTMENTS
DTMF will not reliably decode unless the audio is properly de-emphasized. Strap
JP-1 must be left installed if you have connected directly to the detector. If
you have taken audio past the receiver's built-in de-emphasis, remove the JP-1
shorting clip.
While receiving a transmission containing a CTCSS or DCS code (preferably about
600 Hz. deviation) adjust the GAIN potentiometer P1 for 1.4 volts peak-peak
measured at TP-1 using an oscilloscope. (TP-1 is located between the large fuse
and the RS-232 jack). If an oscilloscope is not available, turn P1 fully CCW
and increase CW until LED D7 just begins to light. (D7 is adjacent to the P1
GAIN potentiometer). Be sure to make this adjustment only when a CTCSS or DCS
encoded signal is being received. Be sure a signal with CTCSS or DCS is
present, because the LED may also light on receiver noise when no signal is
present resulting in an incorrect P1 setting.
NOTE: TP-2 is not used.
If you wish to decode DCS, you must select the correct polarity. Each DCS code
has an incorrect inverse code if the polarity is inverted. Remove or install
the DCS polarity select strap JP-2 until the display indicates the correct code
while receiving a known DCS code.
OPERATION
The CD-2 is fully automatic. When a tone or code is decoded it appears in the
digital display and one of the front panel LED's illuminates to indicate which
type of tone or code is being decoded.
The displays used in the CD-2 are not capable of directly displaying the *, #,
A, B, C or D. The * and # are displayed using - and ||. A, B, C and D are
displayed using the numbers 1. 2. 3. and 4. Note that these are distinguishable
from 1 2 3 and 4 because decimals accompany the digits. The Table below shows
all the DTMF digits and how they appear on your CD-2.
1 = 1 5 = 5 9 = 9 A = 1.
2 = 2 6 = 6 0 = 0 B = 2.
3 = 3 7 = 7 * = - C = 3.
4 = 4 8 = 8 # = || D = 4.
If a DTMF code occurs, the CD-2 temporarily stops displaying CTCSS or DCS and
displays the DTMF activity. When the DTMF concludes, the CD-2 replays the
entire sequence (up to 128 digits) slowly so that you can observe ANI and
speed-dialer codes that would be otherwise too fast to comprehend. Afterward,
the CD-2 resumes decoding CTCSS or DCS automatically.

ABOUT the RS-232 SERIAL PORT
IBM Compatible Personal Computers use either DB-9 or DB-25 serial COM ports.
The DB-9 is more commonly used in recent years, therefore we have provided a
DB-9 to RJ-11 adapter along with a seven foot, six wire phone cord. If your
computer uses a DB-25 connector, you must obtain a DB-9 male to DB-25 female
adapter from your favorite computer store.
NOTE: Only a six wire phone cord with locking tabs on same side of cord may be
used. A six wire cord is supplied.
The RJ-11 to DB-9 adapter is wired as follows (with the locking tab up and the
modular phone jack facing you, pin 1 is on the right. This wiring is for a
"standard" 6 wire phone cable with the locking tab on the same side on both
ends. (This reverses pins 1-6 through the cable). If you wish to wire a DB-25,
then it is shown here also:

6 20 DSR --|(Must be shorted)
In addition, DB-9S pins 4 and 6 are shorted. (DTR to DSR). The equivalent pins
are 6 and 20 on the DB-25S. Although you see a lot of RJ-11 to DB-9/25
adapters, there is no standard for their connection. The adapters are available
commonly in many electronic stores. If you are connecting to a modem, you will
need a null modem adapter to reverse pins 2 and 3 of DB-9S or to reverse pins
7 and 8 of the DB-9S.

CD-2P APPLICATION PROGRAM
INSTALLATION
If you purchased the CD-2P Program, you received a single 3.5 inch PC DOS
compatible disk containing the CD2P.EXE application and an install program.
The easiest way to install is as follows: (The symbol <CR> refers to the
keyboard "ENTER" key.)
1) Place the new disk into your 3.5 inch drive.
2) Make this drive the current drive. If it is drive A:, type A:<CR>. If
it is drive B: type B:<CR>.
3) Type install<CR>
Install will ask you on which hard drive you wish to install the program and
in which directory. It will modify autoexec.bat on drive C: if required. This
will allow you to run CD2P in any directory on your PC.
4) When installation is complete, remove the disk from your PC and reboot.
Reboot either by pressing CTRL+ALT+DEL or by pressing RESET or by
cycling power to the computer. (If it is not convenient to reboot now,
then you will need to run CD2P in the installation directory until you
do reboot.)
5) Attach the CD-2 to either COM1 or COM2 serial port on this PC. See the
instructions above about making the connections to the DB-9 or adapting
to a DB-25 on your PC.
INTRODUCTION to the CD-2P APPLICATION
After installation of the CD-2P application on your computer, installation of
the CD-2 on your receiver or service monitor, and after connecting the CD-2
serial cable to the PC, you are ready to explore the power of the CD-2P
application. This is a summary of the features and screens available to you
with this program.
Main (Run) screen (F1 or R)
Displays a scrolling log of all received data from the CD-2 and a
continuous log of the 22 most recently decoded
Initialization Screen (F4 or I)
Allows setup of the COM port and selection of the codes to be monitored.
Tone Detection (Used Tone) Screen (F8 or U)
Displays the complete list of 163 CTCSS/DCS codes and indicates whether
codes that were detected during the monitoring time.
Time of Day Screen (F2 or D)
Displays accumulated code duration's and sum of all usage as a percentage
of available time each hour of the day.

6
Hit Screen (F3 or H)
Displays Hits per code (A Hit is a detected code lasting 2 seconds or
longer).
Total Time Screen (F7 or T)
Displays the total accumulated time for each code enabled by the
initialization screen.
Observe Programming Screen (F5 or O)
Displays programming data in readable English for CSI TP-154 and/or TP-
154PLUS repeater tone panels when any such data has been received during
connection of the CD-2P program.
Help Screens (F1 or ?)
These are context sensitive help which shows details about the options
available to you at any given stage.
RUNNING THE CD-2P APPLICATION
To run the program type CD2P at the command prompt. There are two switches
available, but normally they will not be used.
1. /S[IM] Runs CD2P in a simulate mode. This reads a file named CD2P.SIM
in your local directory (if it exists) and updates the display with a
new line every 1 second. This can be used to demonstrate the capability
of the program.
2. /U[PDATE] Reads the file CD2P.LOG which contains information from
previous sessions into the program. This allows data to be combined
with current data to observe the information previously collected.
For example, to use the update option, type CD2P/UPDATE or CD2P/U at the
command line prompt.
When the program starts, you will first see the Connect Systems, Inc. welcome
and copyright notice. After pressing any key, you will see the Main Run Screen
with just the headings and the "F1 or ? for help" prompt. Figure 1 shows the
Main Run Screen.
As valid data is received, it is added to the CD-2 Log at the left of the
screen. (Data is filtered by the program so that invalid data is not recorded.)
If a line is too long to display on the half screen available, then the line is
"wrapped" with a back slash "\" at the end of the line. (This back slash will
not be in the data received from the CD-2.)
At the same time the accumulation table on the right is updated every second.
This table is sorted in order of CSI user number, which has CTCSS codes first
and DCS codes last. If more than 22 codes have been recorded then only the most
recently recorded 22 are shown on the screen.

7
The Total column shows the total time in HR:MIN:SEC format. This is the total
time which was accumulated under that code during the time the program was
running plus the accumulated time from the CD2P.ACC file, if it was previously
saved. In addition, the time from the log (CD2P.LOG) if /UPDATE was used is
included.
The Hits column shows the total number of hits or conversations recorded. A hit
is any continuous activity with gaps of no more than 2 seconds.
The Dials column counts the number of DTMF dialing lines which were recorded
from the CD-2.
The Since column shows the number of HRS:MIN:SEC since the last recorded time
for that code. If the time exceeds 999 hours, the time field is replaced with
a days display.

Figure 2. Initialization screen
In the initialization screen, you may change the COM port, change the printer,
add codes to monitor, or delete codes to monitor.
To change the COM port, move the cursor (with the arrow keys) to the PORT line.
By pressing the space bar, you may toggle the COM port from 1 to 2 and back.
Pressing the letter S will save any settings from this screen to a file named
CD2P.INI.
The enabled codes are followed by an asterisk (*). The disabled codes are
followed by a minus (-).
To change the selection of a code, move the cursor to the * or - next to the
code to change. For example, you wish to disable 74.4, place the cursor under
the * following 74.4 and press the space bar. The * will change to a -. To
disable display of all codes, press the '-' key (usually to the right of the
zero key). All codes will change to disabled. To enable all codes press the
asterisk key (usually shift 8). The easiest way to enable a limited number of
codes is to press the - key then use the cursor to move to the codes you wish
to enable and use the space bar to enable the selected code(s).
The codes selected or deselected remain in effect for the session in which they
were changed unless you save them. Save with the S key while in the
Initialization screen.

OBSERVE PROGRAMMING SCREENS and DOWNLOADING DATA
This set of screens is a powerful adjunct to the TP-154 and TP-154PLUS tone
panels manufactured by CSI. These screens allow you to capture and read, in
plain English the programming information as down loaded from the panel.
In order to make use of these screens, you will need to download the
information to the CD-2 while the CD-2P program is running. It is suggested
that the TP-154 or the TP-154PLUS be placed into programming mode by
transmitting the access code without CTCSS or DCS encoding. This prevents
retransmission of the access code during this step. The CD-2P program will
automatically recognize any of the full download commands. This includes
*000#00* and *nnn#00* for the TP-154 and TP-154PLUS. It also includes the
accounting data for the TP-154PLUS accessed with *nnn#mmm#k#. Remember, the
TP-154 and TP-154PLUS send data in 124 character bursts in order to accommodate
the slow display of the CD-1, which has no serial port. When the data exceeds
124 characters, you will have to wait approximately 2 minutes between bursts
before the data is complete.

13
When the accounting data is downloaded, a file named CD2P.DWN is created or
appended with that data. The file is available immediately for your
observation. Figure 7 is an example of the CD2P.DWN file format.

After downloading accounting data, be sure to clear the data using K=7, 8, or
9 per the TP-154PLUS manual, page 37, "DOWNLOADING TIME AND HITS."
When the CD-2P program detects programming data, it maintains that data in an
internal buffer. You may observe the contents of that buffer with the Observe
Programming Screen, examples of which are shown in Figures 8 and 9.

PRINTING of SCREENS
Any of the screens, except the help screens, may be printed at any time by
pressing Control-P. The screen is sent to the printer as normal text and
should print properly on almost any printer. The printer supported is PRN,
which is normally LPT1 unless changed by you. See your DOS manual if you wish
to print to another printer.
IN CASE OF DIFFICULTY
My CD-2 decodes DTMF and some CTCSS codes but does not decode DCS.
You probably have not connected the CD-2 to the actual detector of the
receiver. Connections to the speaker leads or to the volume control do not
have enough low frequency bandwidth to work. Also, be sure the pre-amp level
in the CD-2 is adjusted properly using TP-1 (as described in the manual pages
3 and 4) or using the internal LED sensor.
My CD-2 decodes CTCSS and DCS but not all DTMF digits.
The most likely problem is that the de-emphasis jumper is incorrect. Since DCS
works properly, you probably need the jumper (JP-1) installed.
My CD-2 decodes everything correctly except the DCS codes seem wrong.
You need to change the polarity jumper JP-2. All DCS codes have a positive and
a negative polarity interpretation. If you have the wrong polarity, the
reading will show a valid code, but it will not be what you expect. The
inverse codes are just the binary complement of the direct codes.
My CD-2 decodes everything on the display but I see nothing on my computer
terminal.
Be sure the port is properly selected. If you are not using CD-2P, make sure
the baud rate is correct. If you are using a terminal (not a computer) make
sure you are using a null modem adapter to reverse the TXD and RXD data.
I am using Windows and sometimes when I use the CD2P program, it gives me a
message about which MS-DOS Prompt I want to use.
Windows does not allow the use of the serial ports by more than one window at
a time. Either you are using that serial port in another application, or you
used CD-2P in another window before trying it in this window. If no other
program is using the port, simply tell windows you want to use the other port,
and it will work fine.
I am using Windows, and I lose data whenever I use another window.
Set up the MS-DOS prompt window (Using Settings...) to allow background
running. If your computer is a 386 or better, it should be fast enough to keep
up with the serial data from the CD-2P even with 30% background operation.

16
I accidentally quit CD2P but now I need that data back!
Run CD2P/U. This reads a log file (CD2P.LOG) which allows CD2P to start from
where it left off. Obviously, any data sent while the program was not running
will be lost. Much or all of the data may be lost if the computer crashes or
you turn off power while CD2P is running.
I try to print a screen using the PRINT SCREEN button, but nothing happens.
CD2P can only print the screen with CTRL+P or CTRL+PRINTSCREEN. This is a
side effect of the method used to interpret the keyboard and is not easily
changed.
I try to print a screen using CTRL+P but nothing is on my printer.
The Initialization screen allows you to select your printer or to place the
print results into a file named CD2P.PRN. You may have the printer selection
incorrect. Also, please be sure your printer is actually connected and turned
on and works with other applications.

DESCRIPTION OF CD-2 RS-232 OUTPUT
This section is for those who choose to read the RS-232 output directly or
otherwise have interest in its format. It is not required to understand this
format if using the CD-2P application.
The output of the CD-2 is a very simple, easy to read format, which may be
observed by any terminal emulator program or by making a proper connection to
an ordinary terminal. The serial data rate is 1200 baud and cannot be adjusted.
Set the COM port on an IBM compatible as follows:
MODE COM1:1200,N,8,1,P
Replace COM1 with COM2 if the secondary serial port is used. (While you may use
any serial port compatible with your terminal emulator, the CD-2P program
available from Connect Systems, will only operate with COM1 or COM2.) The MODE
setting is not required when using the CD-2P.
The data is formatted for readability but significant processing is left to
the CD-2P program described in its section in this manual. The format is line
oriented. Each line contains first the CTCSS or DCS code. CTCSS are sent as
the tone frequency of the nominal CTCSS frequency. DCS codes are sent in the
standard octal format. The next character after the code is either a 'C' or a
'T'. A 'C' indicates the line is a CTCSS/DCS line. A 'T' indicates the line is
a DTMF code.
A CTCSS/DCS line ends with the time in seconds representing the time duration
of the CTCSS or DCS code.
A DTMF line ends with the string of DTMF digits received. If the string exceeds
a line length, the line ends with a back-slash (\) and the DTMF codes continue
on the next line. In this manner, DTMF sequences of any length are recorded. A
gap of approximately 3 seconds after any DTMF character terminates the DTMF
line. A DTMF line occurring with no CTCSS nor DCS begins with blanks in lieu of
the CTCSS/DCS code.
An example of an output is shown here:
67.0 C 0021
754 C 0010
462 T 18056427184
462 C 0047
T 18056427271
This shows a tone of 67.0 Hz CTCSS of duration 21 seconds. Later, a DCS code of
754 was heard with a duration of 10 seconds. Later, during a DCS code of 462,
a DTMF sequence of 18056427184 was heard. The duration of the 462 code was 47
seconds. Finally, a DTMF sequence with no CTCSS nor DCS was received. Dead
times are not recorded, real time is maintained by the CD-2P program, if
connected.
