INTRODUCTION
The Whozz Calling? υnit captures Caller ID data and Touch Tone (DTMF) signals from as many as four telephone
lines and sends them to a RS232 serial interface. The unit does not pick-up, go off-hook, or answer the telephone
line. It does not affect the operation of any other devices connected to the telephone line.
The unit can be set to deliver only inbound Caller ID, ignoring all outbound dialed numbers. Or, both inbound and
outbound data can be sent for complete call accounting applications. The data streams can be sent just as the call
begins, just after the call ends, or both at the beginning and the end of the call. The unit can send data in two
different formats of which each has two variations. Incoming calls can be blocked from passing through to the
output jacks. This can be accomplished by dynamic control from the application software or by pre-loading blocked
phone numbers into the unit's memory. First ring suppression to the output jack also can be performed. Setting this
option prevents office employees from answering the telephone too quickly and thus inhibiting the Caller ID signal
from being delivered. Finally, the unit can be set to deliver all detail information occurring on each telephone line.
This includes every occurrence of Ring Signal, Off Hook, On Hook, and Hook Flash.
The Whozz Calling? unit uses setup toggles to determine how the unit will operate. The toggles are either upper or
lower case and are stored in non-volatile memory. For information on unit toggles, please refer to page 3. Operating
commands are used to list the setup parameters, input phone numbers in memory, and reset the system. The Send
Data commands are used to set line numbers, internal clock, and phone numbers for internal blocking.
The manual is designed for the individual that prefers to quickly get the unit running and start experimenting
immediately. The quick start procedure section is followed by a brief discussion of the setup toggles, commands,
and data formats. Later, the manual gives a detailed explanation of all setup toggles, commands, and data formats, a
discussion of Private and Out-Of-Area Caller ID types, and instructions on connecting units together.
QUICK START PROCEDURE:
Refer to Fig. 1, on page 2 when connecting unit.

Plug in the power supply and make sure the red Power LED is on.
Connect the supplied 9 pin cable to the female serial connector on unit marked “To Computer”.
Connect the same cable to an available serial port on the computer.
Plug in up to four phone lines into the input jacks marked "IN" on the unit.
Use any terminal emulation program or modem software set to terminal mode.
Set communication parameters to 9600 Baud, 8 Bit, 1 Stop, No Parity.
When turned on for the first time, the unit is set to communicate at 9600 Baud, 8 Bit, 1 Stop, No Parity. All setup
toggles are set to their upper case values, but they can be changed later. The order of how the toggles are input or
displayed is not important. They are stored in non-volatile memory so that if the unit loses power, the toggles will
remain set. To display the toggle settings at any time use the "V" command. On start-up, the "V" command will
display:
Vx.x ECXUDASOBKT L=01 00/00 00:00:nn
Where Vx.x is the version number of the firmware, ECXUDASOBKT are the setup toggles, L=01 represents line
number to which the first port of the unit is set, 00/00 is the date, and 00:00:nn is the time of the internal time clock
(in HH:MM:SS).

For simple Caller ID applications, we suggest the following toggle setup:
ECXUDaSOBKT
The combination of a lower case "a" and an upper case "S" instructs the unit to send call information only at the start
of each call. With upper case "O" set, the unit will not report call information on outbound calls. This combination
of toggles gives the simplest configuration for Caller ID only applications. The toggles can be configured in either
upper or lower case and combinations set to support various applications such as Call Accounting, Integrated Voice
Response (IVR) applications, Modem/Telephone Security, and Telephony Diagnostics.
All toggles can be changed by simply typing the new toggle. The unit is designed to accept one toggle at a time. If a
software application sends an initialization string of toggles to the unit, a short pause of at least 50 milliseconds
should be inserted between each toggle so the unit it has enough time to write the entry to non-volatile memory.

IN-DEPTH DISCUSSION OF TOGGLES, COMMANDS, AND FORMATS
Setup Toggle Discussion
E,e Echo
Unit will or will not echo back commands that are sent to it. Set to lower case "e" for echo on.
C,c Leading $ character and dashes removed in phone number field
Some applications need to detect a certain character in order to perform an operation. When this toggle is set to "c",
the unit places a "$" character before each data string. This includes detail data strings such as Ring, Off hook, On
hook, and Hook flash (see toggle "D,d"). Also when c is set, the dashes are removed from the telephone number
field. The telephone number justification remains as set by the "X,x" toggle.
X,x Format Options
Two different data formats can be sent by the unit. The limited format sends the line number, date and time, phone
number, inbound/outbound indication, and name (if available). The comprehensive format sends the same along
with the duration of the call, checksum indication, and number of rings. The comprehensive format is strongly
recommended. More detail on these formats on page 9.
U,u Internal Block/Pass
The unit can block or pass incoming calls based on a match against phone numbers pre-loaded into the on-board
memory. The "u" toggle turns on the Block/Pass feature. The "K,k" toggle determines whether the unit blocks or
passes calls that match these numbers.
K,k Block or Pass Select
Set "K" to pass all calls until defeated. Set "k" to block all calls until defeated. These toggles can be defeated by
either the "W" command sent by the host computer or signal sent by the internal memory when a phone number
match is found.
A,a Data Delivery Option (Start & End or Start/End)
The unit is capable of delivering a data stream to the host computer immediately as the call arrives, when the call
terminates, or both. For an inbound call, immediate data delivery allows the Caller ID information to be utilized
before the call is answered for purposes of database queries, call routing, etc. Delivering the data stream after the
call ends provides additional information about the call to the application program such as, the duration of the call
and the number of rings before the call was answered. If lower case "a" is set, data is sent as defined by the "S,s"
toggle.
S,s Data Delivery Option (Start/End)
For this toggle to affect operation "a" must be set. If call data is to be sent before the call is answered, set toggle to
"S". If call data is to be sent only after call terminates, set toggle to "s". If call data is to be sent before and after the
call, set toggle "A".
B,b First Ring Suppression
When this toggle is set to "B", the first ring to the output jack on each line is suppressed. Since the Caller ID stream
is sent between the first and second rings on the telephone line, this prevents the call from being answered before the
information is sent. However, in some cases, hearing the first ring might be essential for the user to respond to the
call in a timely manner. If this is true, set this toggle to "b".
6
D,d Detail Information
Some software applications may need additional call data. When the lower case "d" toggle is selected, the unit can
provide an indication for Ring, Off hook, On hook, and Hook flash. The format is as follows: line number (nn);
space; and either a R (Ring), F (ofF hook), N (oN hook), or H (Hook flash). The date and time (HH:MM:SS)
follow at the same offset as the date/time field in the comprehensive format. In the detail mode, the time is delivered
in a 24 hour format. (Please note: If the "c" toggle is selected, a leading "$" will be added to the above data string).
For more information see the section on Detail Mode on page 8.
O,o Inbound/Outbound Select
For basic Caller ID applications, use the upper case "O". If complete call accounting is required, use lower case "o".
The lower case "o" instructs the unit to deliver for both inbound and outbound calls.
T,t Inbound DTMF Monitoring
When set to lower case "t", unit will monitor for DTMF touch tones on inbound calls. This toggle is used primarily
for voice mail and Integrated Voice Response (IVR) applications. The DTMF digits dialed during the call will be
displayed in the "Name" field on the call record sent at the end of the call. If the Caller ID service provides the
caller's name, the name will still appear in the call record sent at the beginning of the call. (If both the Caller ID
name and the DTMF digits are needed use the upper case "A" to have the unit deliver both start and end records.)
Operating Commands Discussion
@
Handshaking character when # is sent
The unit will return "#" when "@" is sent. This can be used to establish communication between the computer and
the unit. One application for this command is a software setup routine that automatically searches for the unit by
sending an "@" character on each COM port and IRQ until a "#" is returned. The corresponding COM port and
IRQ number then can be set automatically in the application.
V
Firmware version and all settings
This command returns the firmware version, all toggle and line number settings, and date & time (in military format)
on the internal time clock. On start-up, toggles will be defaulted to all upper case values; the line number will be set
to "L=01"; and date & time will be set to zero. All toggles and line number settings are stored in non-volatile
memory and will remain saved even if the unit loses power. The internal clock does not run while the unit is off, and
therefore, it must be reset when power is restored. The clock can be reset by the software using the "Z" command or
will be reset on the first good Caller ID signal. Subsequent Caller ID signals with good checksums will continue to
reset the internal time clock with the telephone company's time.
v
Firmware version and all settings
This command returns the configuration of the internal jumper settings. Jumpers on the circuit board configure the
unit to capture either of the 4 types of Caller ID signaling formats used around the world (refer to Appendix A, page
16) as well as the On/Off scheme used by the device. In most cases, the Caller ID signaling format is factory set to
FSK (US type). If the Caller ID signaling type is pre-determined for your area before being shipped, these jumpers
may be set to the pre-determined format. The On/Off-Hook scheme is also set using internal jumpers to either
Voltage or Current Detection (Appendix B, page 18). Below are examples of lower case "v" outputs.
v-VFU (Voltage Detection, FSK, US Type)
v-CFB (Current Detection, FSK, BT/ETSI Type)
J
List all phone numbers in memory
This command lists all telephone numbers stored in non-volatile memory. These numbers can be used to either
block or pass calls to the output phone jacks. (Refer to the section on use of toggles "U,u" and "K,k"). The nonvolatile memory can store up to fifty, 10 digit or 7 digit phone numbers. Phone numbers are entered using the
"Nnnnnnnnnnn" command discussed in Data Entry Command section, see section below.
Q
Delete all phone numbers in memory
This command deletes all telephone numbers stored in non-volatile memory.
7
R
Reset System
This command resets the operating system and resets all toggles to upper case values. It does not reset the line
number or the baud rate. The baud rate can only be changed by moving a jumper on the circuit board, page 13. The
line numbers of the unit can be changed pressing the line select button on the rear of the unit for 2 seconds. The time
clock can be reset by using the "Zmmddhhmm" command (see details below), or by capturing a good Caller ID
signal.
Data Entry Commands Discussion
Nnnnnnnnnnn <CR>
Add phone number to memory
This command allows telephone numbers to be entered into non-volatile memory. These numbers can be used to
either block or pass calls to the output phone jacks. See section on use of toggles "U,u" and "K,k". The on-board
memory can store as many as thirty, phone numbers. Phone numbers entered into memory must be between 7 and 12
digits in length. Any attempt to enter a number less than 7 or more than 12 digits long will cause the unit to send
back a question mark and the number will not be accepted by the memory. Ten digit numbers are common for the
US and Canada. Less than and more than 10 digit numbers are common in other countries.
If you want to add “Private” and “Out-of-Area” and callers to the memory list, refer to the following:
For Private Callers, enter: N77<CR>
For Out-of Area Callers, enter: N66<CR>
Zmmddhhmm <CR>
Set date and time on internal clock
This allows the programmer to set the internal clock on the unit. Since there is no battery backup on board, once
power is removed from the unit, the internal clock resets to "00/00 00:00:00". This command may never have to be
used, due to the following: On the first incoming call with Caller ID and a good checksum, the internal time clock
will be set to the time sent in the Caller ID signal. On every call thereafter, the internal clock is reset to the Caller ID
time. The format for time entry using the "Z" command is mm (month), dd (day), hh (hour), and mm (minute).
Wnn <CR>
Block (or pass) call on line nn
This command should be sent after the Caller ID signal and before the second ring. This way the call can be blocked
(or passed) based on the Caller ID information. If toggle "B" is set, the first ring will be blocked. The application
program determines whether the remaining rings should be blocked or passed. Please note: Normally, toggle "K" is
set. This allows all calls to pass until a "W" is sent by the application (or an internal command is sent by the
hardware memory). In a secure phone line application, the toggle "k" might be set in order to block all calls until the
"W" command is sent (or the internal command is sent by the hardware memory).
Detail Mode Output Discussion
If the toggle "d" is set, all detail information on each call is sent immediately. The detail events include Ring, On
Hook, Off Hook, and Hook Flash. Each event reported by the unit starts with the line number, followed by the
abbreviation of the event, and finally, the date and time. The date and time is offset 13 characters to the right so that
it will appear in the same offset position as the date and time in the comprehensive format. Also, the time is
displayed in a military format so that the time of the event can be determined exactly. An example is shown below.

Error Condition Discussion
A question mark (“?”) is returned on most any input that is not valid. Also, any non-interpretable characters
contained within a Caller ID string will be sent as a question mark. Most likely the checksum will be calculated as
"bad".
8
Format Discussion
Two different output formats are available. They are selected using the "X,x" toggle. The comprehensive format is
preferred by most programmers because more information is delivered about each call. The limited format is not as
informative or flexible, but may be preferred in basic Caller ID applications.
Comprehensive Format - Inbound Calls
The comprehensive format is highly recommended for all applications. The amount of data sent, combined with the
flexibility of sending the data at the end of the call, makes it the format of choice for even very simple applications.
The data string can be, 63 characters in length, including the leading $ sign (if the "c" toggle is set), spaces, the
carriage return, and line feed characters at the end of the data.
The comprehensive format for an inbound call is shown in Fig. 2a. The line number always precedes the data string.
In this example, data from line 3 is discussed.
The Inbound/Outbound and Start/End of Call Indicators use I/O and S/E respectively. Remember that the unit can
be set to send data on inbound and outbound calls or only on inbound calls (toggle "O,o"). Also, the data stream can
be sent at the start of the call, end of the call, or both (see toggles "A,a" and "S,s").
Since the duration of the call is sent only after the call is complete, toggles "O,o" and "S,s" must be set so the unit
will send data at the end of the call.
The Caller ID string sent by the telephone company always contains a checksum. The unit compares its checksum
with the checksum sent by the phone company and displays the either "G" (Good) if the two match or "B" (Bad) if
they do not match. The application programmer may elect to ignore this indicator and determine the validity of the
data after reading in the data stream.
The next field contains both the number of rings delivered by the telephone company before the call was answered
and the type of ring. A service called Distinctive Ring or Ring Master is offered to customers in many areas. It
allows up to 4 telephone numbers to be routed to one phone line. Each phone number dialed causes the telephone to
ring differently. The unit will determine which ring pattern is delivered and mark it as A,B,C, or D. Please note the
number of rings is always zero except when the data is delivered at the end of an incoming call.
The date and time information is sent by the phone company as part of the Caller ID signal on each incoming call.
For each incoming call with a good checksum, the time and date information will be used to reset the internal real
time clock to match the telephone company's clock.
The phone number field for the comprehensive format is 12 characters and left justified. Dashes are inserted when
the "C" toggle is set. If the "c" toggle is set the dashes are removed (and a leading $ sign is inserted in front of the
data string). In some areas of the US and Canada, no area code is sent for calls within the local calling area. In this
case, the unit will send the 7 digit phone number, left justified. If the application software will be used in different
areas of the country, it is suggested that the local area code reside in the software to be appended to any 7 digit
number delivery to make it a 10 digit number.
In many areas, the name of the caller will be delivered along with the number. This service is sometimes referred to
as Caller ID Plus, Caller ID Deluxe, or Enhanced Caller ID. If delivered by the local telephone company, the name
will reside in a left justified, 15 character field, following the number field. Names for private residences are usually
sent last name first, space, first name, space, and then middle initial. Business names are most often sent as they are
listed, but if they over 15 characters, truncation will occur. Even though most local telephone companies send all
upper case names, the Bellcore and Bell Canada specification provides for the delivery of both upper and lower case
characters.

Comprehensive Format - Outbound Calls
Figure 2b shows the Comprehensive format for outbound calls. Unlike figure 2a, toggle "c" is set. (Remember
toggle "c" places a $ sign before the data stream and removes dashes in the phone number field.)
The outbound indicator displays O and the Start/End indicators are the same as inbound calls. The duration of the
call is only sent at the end of the call and is displayed in seconds. The checksum indicator is always "good" and the
number of rings remains "zero" at all times. The date/time displayed is the date/time that the call was initiated and
does not change at the end of the call. The unit tries to be as "smart" as possible in determining where to place
outbound dialed digits. Digits dialed are placed in either the number or name field. The algorithm below explains
where the unit places digits.
All digits dialed within 2 seconds of each other will be displayed beginning in the number field. If more than 10
digits are dialed, the additional digits will be displayed in the name field. The "Start" data string for outbound calls
will be sent immediately after a period of 2 seconds when no digits are dialed. Any digits dialed after this 2 second
interval will be displayed in the name field and will be displayed only at the end of the call. In the example in Fig.
2a, second data string, the 800 number was originally dialed. After a few rings, an automated answering device
answered the call. The caller then dialed additional digits responding to voice menu selections.
An exception to this 2 second rule provides for 7 and 10 digit numbers to be reported in the number field on the end
record, regardless of the interval between dialed digits.
Limited Format - Inbound Calls
The limited format is designed for simple inbound Caller ID delivery. Even though outbound dialed numbers can be
captured, it is recommended for only the simplest call accounting applications. Even if your application only
requires simple inbound Caller ID data delivery, we still recommend the comprehensive format over the limited
format. In this way, your application can grow with the increasing needs of your business.
The limited format for an inbound call is shown in Fig. 3a. The data string can be up to 73 characters long including
the leading $ sign (if "c" toggle is set), spaces, and the carriage return/line feed characters at the end of the data. The
line number always precedes the data. Data for line 3 is discussed in this example.
The date and time information is sent by the phone company as part of the Caller ID signal on each incoming call.
For each incoming call with a good checksum, the time and date information will be used to reset the internal real
time clock to match the telephone company's clock.
The phone number field for the comprehensive format is 14 characters and RIGHT justified. Dashes are inserted
when the "C" toggle is set. If the "c" toggle is set the dashes are removed (and leading $ sign is inserted in front of
the data string). In some areas of the U.S. and Canada, no area code is sent for calls within the local calling area. In
this case, the unit will send the 7 digit phone number, RIGHT justified. If the application software will be used in
different areas of the country, it is suggested that the local area code is stored in the software and added to any 7 digit
number received so as to make it a 10 digits. In this way, a 10 digit look-up routine can still be used for local calls.
In many areas, the name of the caller will be delivered along with the number. This service is often referred to as
Caller ID Plus, Caller ID Deluxe, or Enhanced Caller ID. If delivered by the local telephone company, it will reside
in a RIGHT justified, 15 character field, following the number field. Names for private residences will usually be
sent last name first, space, first name, space, and then middle initial (if applicable). Business names are most often
sent as they are listed, but if they are over 15 characters, truncation will occur. Most local telephone companies send
all upper case names, the Bellcore and Bell Canada specification provides for the delivery of both upper and lower
case characters.
For reference, the line number field is 2 characters in length. The date field is 5 characters. The time field is 8
characters. The number field is 14 characters. The Inbound/Outbound field is 1 character. The name field is 15
characters. The carriage return line feed characters are sent immediately after the last data character. Therefore, no
spaces are sent to fill the remaining characters in the last field. All fields are separated by 5 spaces in the limited
format.

Limited Format - Outbound Calls
Figure 3b shows the Limited Format for outbound calls. Unlike figure 3a, toggle "c" is set. (Remember toggle "c"
places a $ sign before the data string and removes all dashes in the phone number field.)
The date and time come from the on-board time clock. The Inbound/Outbound indicator is placed between the
number and name field. All digits dialed within 2 seconds of each other will be displayed beginning in the number
field. If more than 10 digits are dialed, the additional digits will be displayed in the name field LEFT justified. The
data string for outbound calls will be sent immediately after, a period of 2 seconds, when no digits are dialed. Any
digits dialed after this 2 second interval will not be reported. Remember that the data string for limited format
cannot be sent after the call is concluded. Therefore, once the data is sent at the beginning of the call, any digits
dialed thereafter, will not be reported.
For reference, the line number field is 2 characters in length. The date field is 5 characters. The time field is 8

DISCUSSION OF PRIVATE AND OUT-OF-AREA CALLERS
Two unique messages can be delivered as designated by Caller ID specifications. An "Out-of-Area" message occurs
if the information on a caller is unavailable. This is true for most cellular calls and is sometimes the case when the
call originates outside the telephone company's Local Access Transmission Area (LATA). This loosely translates to
long distance calls. In the near future, Caller ID will be delivered on a long distance basis. Inter-LATA and
interstate Caller ID delivery is scheduled to begin in all areas by June, 1996.
A "Private" message is sent for callers who have blocked their Caller ID number from being transmitted to the called
party. Blocking can occur either on a per call or on a per line basis. For per call Caller ID blocking, a code (*67)
can be dialed before each call is made. In some areas, customers can request that all calls from their line be
permanently blocked. In either case, the recipient of calls from these numbers will receive a "Private" or
"Anonymous" indication from their Caller ID device.
Private and Out-of-Area messages can occur in either the number or name fields if number and name service is being
delivered. For example, some telephone companies allow customers to have private numbers, but names are always
sent. In another case, the number might be sent, but the name of the customer is Out-of-Area. This would most
likely happen if the customer had just received new service and the telephone company's database had not been
recently updated. Be aware that your application software might need to handle various combinations of number,
name, private, and out-of-area messages in both the number and name fields.
CONNECTING UNITS TOGETHER
Use the supplied serial cable to connect unit #1 with unit #2. The cable attaches to the unit #1 port marked "To Next
Unit" to the unit #2 port marked "To Computer." Unit #2 connects with unit #3 in the same manor.
SETTING LINE NUMBERS ON INDIVIDUAL UNITS CONNECTED TOGETHER
As many as 7 monitoring Caller ID units can be connected together into one serial port. Each unit has a line selector
switch located on the rear panel. This switch is used to set up additional units for the appropriate line numbers.
Each time the switch in depressed for 2 seconds the line numbers on the unit will increase by four. For example, the
switch should be pressed once for the second unit to set it for lines 5 through 8. The switch should be pressed twice
on the third unit to set it for lines 9 through 12. Additional unit line numbers can be set accordingly.
The switch will set line numbers up to 49 and then roll over to 1. Loss of power to the unit will not affect line
numbers set by the switch. The line number set for channel 1 of each unit can be seen in the HyperTerminal program
13
described in Appendix E – "Using Hyperterminal In Windows to Monitor Unit", page 22. Within the main terminal
screen, type a capital “V” (for version). The unit will respond with the version of the firmware, unit toggle settings,
and the line number of Channel 1.
Use the supplied serial cable to connect unit #1 with unit #2. The cable attaches to the unit #1 port marked "To Next
Unit" to the unit #2 port marked "To Computer." Unit #2 connects with unit #3 in the same manor.

Appendix A - International Caller ID formats and Internal Jumper Settings
Caller ID is a data signal generated by the phone company's central office (CO). The type of Caller ID signal that
will be sent by a phone company will depend on the type of equipment in use at their CO.
Caller ID signaling formats vary throughout the world. At present, there is four basic formats with local variations of
each format type. By setting the proper combination of internal jumpers (shunts), the Whozz Calling? unit can
capture any of these four basic Caller ID signaling formats. The four basis formats are:
1.
2.
3.
4.
Bellcore 202 - USA Type. Sent in many countries. FSK sent between the 1st and 2nd ring cycle.
British Telecom – Only Sent in United Kingdom. FSK sent before the 1st ring cycle.
ETSI - Sent primarily in Western Europe. FSK sent after very short 1st ring.
DTMF - Sent in regions that use older CO equipment. DTMF (touch-tones) sent before the 1st ring.
NOTE: Refer to the table in Fig. A1 for more information on known formats in particular countries.
The standard factory setting for Whozz Calling? units is to capture Bellcore 202 type Caller ID. If the signaling
format was determined in advance of the unit being shipped, the Whozz Calling? may be set for an alternate format.
In order to configure the unit to a different Caller ID signaling format, the top of the enclosure must be removed and
shorting jumpers moved on the circuit board. Use the following steps and refer to Fig. A1 on the next page.

Appendix B - On and Off-Hook Detection (Voltage vs. Current)
The Whozz Calling? detects when the phone is on-hook and off-hook. This allows the unit to determine the length
of each phone call and report this detailed information to the software. Telephone monitoring equipment can detect
the occurrence of the On Hook and Off Hook status of the phone line by two methods. It can either sense the voltage
on the phone line itself or sense current flow on a phone line passed through the equipment.
Voltages on incoming central office (CO) phone lines are consistent among all branches throughout a physical
location (building). If the voltage levels are in standard range, monitoring equipment functioning in a voltage
detection mode is able to sense On and Off Hook on any branch in the building. The obvious advantage to this
detection scheme is that the monitoring equipment can be connected in parallel to the CO lines . Your unit comes
from the factory set to voltage detection mode because, in most locations, this detection scheme works properly.
Current on phone lines only flows to the telephone device that is Off Hook. Monitoring equipment that senses On
and Off Hook by means of current flow must be connected between the phone company’s incoming line and the
device(s) that goes Off Hook. The current will flow through the monitoring equipment to the Off Hook device.
With this detection scheme, any telephone device that makes or receives phone calls must be attached in series (i.e to
the output jacks) “behind” the monitoring equipment.
VOLTAGE DETECTION CIRCUITRY AND TELEPHONE LINES
In order to sense the voltage on the phone line, the unit’s circuitry must draw a small amount of current from the
phone line. The current draw is very small (70 µA, similar to a voltmeter), and is drawn when the phone line is On
Hook. The telephone company’s amplifier supplying the power to your location may not be able to supply this
current and still keep the On Hook voltage level within the standard range. This occurs primarily in older residential
and commercial locations. An unsophisticated telephone company repair technician may diagnose this small current
draw by the unit as a “short” on the line. Therefore, the telephone company will not address the shortcoming of their
supply amplifier. If this situation occurs, the unit cannot be used in the voltage detection mode, it must be
reconfigured to the current detection mode.
RECONFIGURING UNIT TO CURRENT DETECTION MODE
In order to configure the unit to a different Caller ID signaling format, the top of the enclosure must be removed and
shorting jumpers moved on the circuit board. Use the following steps and refer to Fig. B1on the next page.
1.

Remove the top of the enclosure by first removing the two Phillips head screws on the bottom of the unit.
Slide the top of the enclosure off.

APPLICATION NOTES
Pin 6 is connected only between multiple Whozz Calling? units and acts as a control line. When units are not
transmitting data this line resides at -9 VDC. Upon transmit, the unit pulls this line to +9 VDC. Other Whozz
Calling? units connected will detect this as a busy condition and will not transmit until the line returns to -9 VDC.
If your application program is designed to perform software controlled real time call blocking/passing it is important
that the Pin 6 control line is at the very least, monitored for the busy condition. Since units cannot transmit and
receive data at the same time, any commands that are issued by the software must be sent while units are not
transmitting. The best solution is to monitor the control line on Pin 4 and pull it high with Pin 6 when your software
is transmitting. This method will assure that commands sent to units will get through. This line should be pulled
high by your serial port through a standard 1N4148 diode as diagrammed below.

Appendix D - Requirements and Compatibility
COMPUTER REQUIREMENTS
The unit must be connected to a dedicated serial port (either 9 or 25 pin) on your computer that is free of COM port
and Interrupt (IRQ) conflicts. It is not required that the serial port reside on any particular COM number or IRQ
value. This is important only to application software that you may be running in conjunction with the unit. The
requirements for computer CPU speed, disk drive space, memory, and operating system are determined by the
software application you are running.
PHONE LINE COMPATIBILITY
The unit should be connected to the telephone lines coming into your building commonly know as the Central Office
or “CO” lines. These lines are otherwise referred to as flat rate, local loop, or 1FB lines. The unit can also operate
on analog Centrex™ lines. In order to operate the unit on trunk lines (otherwise know as “ground start” lines) you
will have to contact CallerID.com to swap your unit for a current detection model. The unit will not work connected
directly to digital Centrex™, T1, or ISDN lines. If you have an ISDN interface hardware that has analog telephone
outputs. outbound monitoring is possible but only with a current detection unit. Also, with a current detection unit
you can monitor outbound calls if the unit is placed on analog extensions from a telephone switch. See Table 1 for
telephone line type compatibility.
Table 1 - Phone Line Compatibility
Depending on the type of phone line, the unit may be compatible with Caller ID and outbound call monitoring, or
just outbound call monitoring only. The unit senses On/Off Hook by detecting the telephone line voltage levels. If
the voltage levels are not in standard local loop ranges, the unit can be replaced with a current detection model by
CallerID.com to detect On/Off Hook by means of current flow through the device

* Note: T1 circuits terminated with external routers capable of separating and combining Voice and Data
are, in fact, compatible with Whozz Calling? units. These routers supply standard analog 1FB lines to the
phone system.
In order to capture Caller ID, an analog Caller ID signal must be present on the phone line. This signal can be sent
directly from the phone company or certain types of ISDN interface units can regenerate digital Caller ID data as
analog Caller ID signals to its analog ports. Analog Caller ID will not pass through telephone switches to extension
lines. Even Caller ID compatible telephone switches do not pass or regenerate analog Caller ID signals to extensions
lines. Units will not operate if directly connected to digital phone lines.

c) Select: Call/Connect and type any character again and repeat above as necessary.
NOTE:
If a fax/modem board is installed in your computer, the Loopback test performed on this COM port will
give a false positive result. You can check to see if the FAX/modem is on the COM port your testing by
typing “AT” and pressing the “Enter” key. A FAX/modem will return “OK”.
10. If you obtain a positive result, go to “Loopback Test Successful”. If not, you may have a conflict between
your serial port settings and an internal device such as a FAX/modem. Consult your computer technician to
resolve the conflict.
22
LOOPBACK TEST SUCCESSFUL
After a successful Loopback test, reconnect the unit and type a capital “V” (Shift “V”). The unit will respond with
the firmware version number, setup toggles, line number of the first channel, and date & time. The unit is now
communicating with the serial port. Note the COM port number to which you are directly connected.
Make a test phone call on each of the phone lines. If the phone call data appears on your screen, most likely the
phone lines are connected correctly and the unit is working properly.
If you are using application software, exit your terminal program and run your application software again. If phone
call data still does not appear in you application software, determine whether the software can be manually
configured to the correct COM port. Contact your application software provider if problems still persist.
CAPTURING DATA IN A TERMINAL PROGRAM TO A TEXT FILE
Monitoring the output from the unit in a terminal program does not save data unless you capture it to a text file. If
not captured, the data that scrolls off your screen is lost. When you enter your terminal program you must
immediately set it to capture data to a file. Since terminal programs can be set to append data to an existing text file,
you can capture data to the same file every time you run your terminal program. Below are instructions on how to
start capturing data to a text file for three specific terminal programs. If you are using another terminal program
refer to its help instructions.
From the terminal screen:
Windows Hyperterminal - Select: Transfer/Capture Text, and type text file name
Procomm Plus for DOS - Press Alt-F1, type text file name

Appendix F - Explanation Of Start Up Sequence And Front Panel Lights
Once the unit is powered on, it goes through a start up sequence. The power light comes on, the channel lights are
individually pulsed, the relays are pulsed, and the firmware version of the channel microprocessors is sent. This
process takes approximately 5 seconds and thereafter, the unit is operational and is ready to monitor calls.
The unit is shipped from the factory set to detect On and Off Hook by sensing the telephone line voltage (refer to
Appendix B, page 18, for more information). Internal jumpers (shunts) can be set to sense On and Off Hook via
current flow through the unit. Channel lights will operate differently for voltage and current detect modes
VOLTAGE DETECTION MODE (Normal Factory Default)
A solid channel light indicates that a live phone line is attached and is On Hook. A channel light that goes out and
pulses once every second indicates either an Off Hook condition on that line or a live phone line is not attached
The following discussion assumes a live phone line attached to a channel. When a phone goes Off Hook the channel
light goes off and pulses every second . The light will come on during every touch tones dialed. When the phone
goes back On Hook the channel light will return to solid on. On inbound calls, the channel light will follow the ring
pattern on the line. When the ring signal is present the light will be on. Between rings, the light will go off. Also,
when the Caller ID signal is sent between the first and second rings, the light will pulse momentarily
CURRENT DETECTION MODE (When Internal Jumpers are Reconfigured to sense loop current)
Channel lights will remain on except when a live line is attached and is On Hook. When a live line goes Off Hook
the channel light will goes off and pulse every second. As with the voltage detection mode, the light will come on
during every touch-tone dialed. When the phone goes back On Hook the channel light will return to solid on. On
inbound calls, the channel light will follow the ring pattern on the line. When the ring signal is present the light will
be on. Between rings, the light will go off. Also, when the Caller ID signal is sent between the first and second
rings, the light will pulse momentarily
24
Appendix G - Installation Directions
The Whozz Calling? and Scout monitoring units capture all details of inbound and outbound calls and delivers this
information to a computer.
The monitoring unit is designed to collect call data from standard telephone lines (trunk or CO lines) coming into
your building. It will not work properly if connected to extensions (or station) lines coming from a telephone switch.
Connect the unit only to standard local loop start or analog Centrex phone lines. It is not designed for ISDN, T1,
DID, Digital Centrex, or Ground Start lines
The unit connects to your computer through a serial port. The serial port must be free of COM Port and IRQ
conflicts and dedicated to the monitoring unit. The unit can work with any serial port regardless of the COM number
and/or IRQ it is using. Multiple Whozz Calling? units can be connected together (daisy chained) in order to monitor
up to 40 telephone lines on one serial port. Whozz Calling? with Memory and Scout unit cannot be daisy chained.
OVERVIEW OF CONNECTIONS
Phone lines are connected to the back of the unit using modular jacks. Input and output ports are provided for wiring
systems using either 2 wire connections (RJ11 > 1 phone line per phone cord) or 4 wire connections (RJ14 > 2 phone
lines on one phone cord). If the wiring coming into your building does not terminate in modular jacks, contact your
telephone vendor to add modular connections.
The supplied six foot, 9 pin serial cable connects the unit to an available serial port on the computer. If the computer
has a 25 pin serial port, a 9 to 25 pin adapter can be purchased at any computer or Radio Shack store. Additional
monitoring units are connected to one another using the same type cable. Please refer to page 13 for more
information on connecting multiple units.
CONNECTING TO COMPUTER
You may have purchased a software package designed to work in conjunction with the Whozz Calling? unit. The
software may have a built-in automatic search and find function. This routine will search all COM and IRQ numbers
in an attempt to determine settings for the serial port with which the unit is connected. If an error message indicates
that the software cannot communicate or “find’ the unit, you will need to run the Loopback Test to determine if there
exists communication port conflicts within you computer. If your software requires a manual selection of the COM
and/or IRQ settings, the Loopback Test is also helpful in determining these parameters.
The unit should be connected to the serial port, placed in a convenient location next to the computer, and your
software installed. Permanent installation and phone line connections can be made once communications between
the software and hardware is established. Plug in the power to the unit and run the software. Phone lines need not
be connected at this time. The software will either communicate with the unit connected to the computer or display a
message indicating no communication.
If a no communication error is indicated and your software has an automatic search function, it has tried to
communicate with the unit using every combination or COM and IRQ numbers. The serial port is probably not
configured correctly and chances are the COM port number and/or IRQ number defined for the serial port conflicts
with another device such as an internal FAX/ modem. If an auto-search function is not performed within the
software, the COM and/or IRQ numbers must be set manually. Enter different combinations of COM and/or IRQ
numbers to establish communication. If unsuccessful, use the Loopback Test to help determine whether
communication conflicts reside in your computer.
To determine whether a serial port is configured and working properly run HyperTerminal in Windows and
Loopback test procedure below.

CONNECTION TO PHONE LINES
There are two basic methods of connecting the monitoring unit to your phone lines: the series (pass through)
connection, or the parallel (branch off) connection. The series connection uses both input and output modular jacks
on the unit. The parallel connection uses only the input jacks.
Series Connection
Connecting the unit in series allows the use of the first ring suppression feature. Since the Caller ID signal is sent on
the telephone line between the first and second ring, suppressing the first ring will prevent the call from being
answered before the Caller ID data is sent. A series connection allows the user to have the option of suppressing the
first ring simply by selecting it in the software.
Figures 2a & 2b show series connections. Each phone line to be monitored passes through the unit. Phone lines
coming into the building connect to the input jacks on the unit (through bare wire to modular adapters, if needed).
Lines connected to the output jacks continue to the desktop phones (through a phone switch, if present).
Parallel Connection
A parallel phone line connection is often easier since the incoming lines to the building need only "branched off" to
the unit. The unit can monitor the telephone activity simply by being connected to the phone lines of interest. With
this connection only the input ports on the unit are used.
Figures 3a & 3b show parallel connections. This involves branching off or "tapping" from each phone line to be
monitored and connecting them to their respective input jacks on the unit (through bare wire to modular adapters, if
needed). As mentioned above, this method of connection does not provide for first ring suppression capability.
2-Wire (RJ11) or 4-Wire (RJ14) Phone Cord Connections.
Most modular phone cords contain 4 wires which can handle two phone lines (2 wires for each line.) Your system
may have either 2 of the wires connected (RJ11 - 1 phone line) or four wires connected (RJ14 - 2 phone lines). The
modular connectors on the unit are equipped to handle either arrangement. They are marked similar to the modular
connectors on a 2 line phone. For example, Channel 1 is marked “L1 or L1/L2”. L1 is for a 2-wire phone cord and
L1/L2 is for a 4-wire phone cord. Please refer to Fig. 1.
For a 2-wire (RJ11) system one phone cord simply plugs into each channel on the unit. Caution must be observed
when connecting a 4-wire (RJ14) system. Phone cords must only be connected to channels 1 and 3. To prevent
crossed telephone lines, do not connect phone cords to channels 2 and 4 on a RJ14 system.
If you are unsure whether your system is 2 wire or 4 wire a quick check can be made using the unit. First, power on
the unit. Connect one cord to the input of channel 1. If only the Line 1 light comes on, you have a 2-wire (RJ11)
cord. If both Line 1 and Line 2 lights come on, you have a 4-wire (RJ14) cord. Continue checking the rest of your
cords in this manor.

MOUNTING HARDWARE
A one inch wide black plastic mounting bracket is used to attach the unit to a wall or phone board. Remove the two
Phillips head screws on the bottom of the enclosure and attach the bracket to the unit with the same screws. Mount
on wall using appropriate hardware.
DAISY CHAINING MULTIPLE UNITS
As many as 7 monitoring Caller ID units can be connected together into one serial port. Each unit has a line selector
switch located on the rear panel. This switch is used to set up additional units for the appropriate line numbers.
Each time the switch in depressed for 2 seconds the line numbers on the unit will increase by four. For example, the
switch should be pressed once for the second unit to set it for lines 5 through 8. The switch should be pressed twice
on the third unit to set it for lines 9 through 12. Additional unit line numbers can be set accordingly.
The switch will set line numbers up to 49 and then roll over to 1. Loss of power to the unit will not affect line
numbers set by the switch. The line number set for channel 1 of each unit can be seen in the HyperTerminal program
described above in this section and in Appendix E – "Using Hyperterminal In Windows to Monitor Unit", page 22.
Within the main terminal screen, type a capital “V” (for version). The unit will respond with the version of the
firmware, unit toggle settings, and the line number of channel 1.
Use the supplied serial cable to connect unit #1 with unit #2. The cable attaches to the unit #1 port marked "To Next
Unit" to the unit #2 port marked "To Computer." Unit #2 connects with unit #3 in the same manor.
