Whozz Calling? POS
Technical Manual
[V1.2 - 03/17/2006]
Introduction
The Whozz Calling? POS reports telephone line number and Caller ID information. Caller ID information consists of
date, time, caller’s number and caller’s name (if sent). This information is sent via serial stream to any serial device
such as a printer or a computer immediately after Caller ID data is captured. Data can be sent at either 9600 or 1200
Baud. Two different formats are available. The CallerID.com format conforms with all other Whozz Calling? products.
The limited format matches the TCI, MLX series format. If multiple units are to be connected together, each individual
unit can be set for different line numbers. All options, formats, and addresses are set using DIP switches located on the
front panel of the unit.
Telephone Line and Serial Communication Requirements
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 analog loop start, ground start, or Centrexphone lines. It is not designed for ISDN, T1, T3,
E1, E3, DID, or Digital Centrex type phone lines
The unit can be connected to a printer or to a computer through a serial port. A serial printer connects using a null
modem adapter or null modem cable. A parallel printer requires a serial to parallel converter as well as a null modem
adapter. If connected to a computer, 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.
Quick Start Procedure
In order to see Caller ID information on your computer, you will need some type of serial communications program such
as HyperTerminal, PC Plus, PC Anywhere, etc. Follow the instructions below for connecting to your computer and refer
to Fig. 1.
1. Connect the supplied 9 pin cable to the female serial connector on unit marked “To Computer”.
2. Connect this same cable to an available serial port on the computer.
3. Plug in 2-wire RJ11 phone lines into the modular phone jacks on the unit.
4. Use any terminal emulation program or modem software set to terminal mode.
5. Set communication parameters to 9600 Baud, 8 Bit, 1 Stop, No Parity.
6. Plug in the power supply and make sure the red channel LEDs light.*
7. Make a phone call to one of the lines connected to the unit. The Caller ID information will appear
on your screen.
*The power up sequence of the unit will flash the LEDs and a couple of seconds. The unit will send the firmware
version number of each channel to the serial port when the DIP switches are positioned to send the CallerID.com format
(Fig. 2a).

CALLER ID DELIVERY TYPE
Caller ID signaling is sent by the local phone company's central office in either of two different electronic formats.
Frequency Shift Keyed (FSK) signaling is used in the countries were newer central office equipment is installed such as
the US, Canada, and Australia. In countries or regions where older central office equipment is used Caller ID is
delivered via DTMF (touch-tones).
This unit is capable of capturing either FSK or DTMF type Caller ID signaling.

The CallerID.com format is recommended since it is the industry standard. This format is used with all other
CallerID.com products with serial output. Several software vendors have adopted this standard since it gives them the
flexibility to handle any type of call accounting application. The CallerID.com format provides additional fields for
outbound digits dialed, inbound digits dialed after answer, number of rings before answer, call duration, and type of
distinctive ring pattern. The Standard Whozz Calling? reports this additional phone call information. Even if your
present application does not require this additional information, we still recommend using the CallerID.com format so
that future applications may be converted to read the additional data. Please refer to Fig. 2a for the exact format
specifications.
CONNECTING 4 LINE MODELS TOGETHER
When connecting multiple Whozz Calling? POS 4 line models together set DIP switch #8 to ON. The DIP switches 1-3,
used to set the correct line numbers for each unit, will increment line numbers by 4 instead of 8. For example, the first 4
line model would have DIP switch #8 ON (and #1,#2 & #3 OFF) to set it for line numbers 1 through 4. The second unit
would have #8 ON, #1 ON (and #2 & #3 OFF) for lines 5 through 9.
Model DIP Switch #8
8 line -
4 line ON
Serial Connections and Phone Connections
The supplied six foot, 9 pin serial cable connects the unit to a serial equipped device such a printer or computer. If your
printer or computer has a 25 pin serial port, a 9 to 25 pin adapter is recommended. If connected directly to a serial
printer a null modem adapter will be required. These adapters are available at any computer or Radio Shackstore.
Additional monitoring units are connected to one another using the supplied 9 pin cable. Please refer to page 3 for more
information on connecting multiple units.
Phone lines are connected to the back of the unit using modular jacks. Input and output ports are provided for wiring
systems using 2 wire RJ11 connections. If the wiring coming into your building does not terminate in modular jacks,
contact your telephone vendor to add these modular connections.
CONNECTING DIRECTLY TO A PRINTER
Printers have either a serial or parallel input. Most newer printers use parallel connections. A parallel printer will
require a separate serial-to-parallel converter unit.
A null modem adapter or cable must be used when connecting a printer directly to the unit. The monitoring unit sends
information out on pin 2 while a serial printer or serial-to-parallel converter receives information on pin 3. The null
modem adapter reverses the transmit and receive pins by connecting pin 2 to pin 3 and pin 3 to pin 2,. (The null modem
adapter is not required on a computer serial port which receives information on pin 2.)
A 9-25 pin adapter may also be required and is available a any computer or Radio Shackstore.
Serial printers are available from only a few manufactures. Okidata Corporation carries at least 2 different models. Ask
for Model 590 with serial option or Model 395 with serial option.
Set your printer to 9600 Baud, 8 Data Bits, 1Stop Bit, No Parity. The unit sends both Carriage Return and Line Feed
commands, so the printer should be set to No Automatic Line Feed.
CONNECTING TO A 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 to 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 below 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.

6
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.
Your software will require that you set the COM port number to which the unit is connected. Try different COM
numbers to establish communication. If no communication can be established then chances are serial port is not
configured correctly or the COM port number and/or IRQ number defined for the serial port conflicts with another
device such as an internal FAX/ modem. To determine whether a serial port is configured and working properly use
HyperTerminal in Windows and Loopback test procedure on the following page.
Loopback Test for a Serial Port Connection in Windows
1. Make sure your software program that runs in conjunction with Whozz Calling? is closed.
2. From your Desktop Select Start and then Run. Type HyperTrm.exe and click "OK"
3. In the Connection Description dialog box Type: “Test” on the Name line and Select: OK
4. In the Phone Number dialog box leave phone number blank and Select: Connect using Direct to COMx. Where
“x” represents the COM port number being tested (ex. 1,2,3, etc.) Select: OK
5. In the Properties dialog box Select Bits per second:9600, Data bits: 8, Parity: None, Stop bits: 1,
and Flow Control: None. Then Select: OK
6. Select: File/Properties. In the Test Properties dialog box select the Settings tab and set Emulation
toANSI. Select ASCII Setup and make sure that Echo typed characters locally box is not checked.
Select: OK to close and OK again to close the Test Properties box.
7. Disconnect the serial cable from the unit, and attach the supplied Loopback Connector to the cable
(the other end is connected to the serial port on the PC).
8. Type any character.
a. If the character you typed shows on the screen, the serial port is functioning properly, the test is
positive.
b. If you do not see the character COM port and click OK.
c. Select: Call/Connect and type any character again and repeat above as necessary.
9. If you obtain a positive result, close HyperTerminal and run the your software again. 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.
CONNECTING TO PHONE LINES
The unit will only capture Caller ID when connected to the central office phone lines coming into the building. The unit
will not function properly when connected to extension lines from a telephone switch. If your wiring is modular, simple
modular splitters will be required to form a "Y" or branch circuit such that each phone line can connect to the Whozz
Calling? POS unit in parallel.
If your existing telephone wiring is not modular, consisting of "punched down" solid wire connections, it is
recommended that a qualified telephone technician adapt modular connectors for the installation. Figure 2 diagrams the
parallel connections required for proper installation.
4-Wire (RJ14) Phone Cord Connections
Most modular phone cords contain 4 wires which can supply 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 only 2-wire RJ11 connections. If you have a 4-wire (RJ14) system,
consult with a telephone technician to convert them to a compatible 2-wire RJ11 system.
MOUNTING HARDWARE
A 1 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.

Even if your telephone system switch is Caller ID capable, it will not pass analog Caller ID.
Therefore, the POS series units must be connected to the phone lines coming into the building from the
telephone company. These lines are branched (split or half-tapped) and connected to the input jacks of
the monitoring unit. If these lines are not modular, solid wire to modular adapters must to be installed

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 connecting to a 25 pin serial port on the computer, we suggest using a 9 to 25 pin serial adapter. The pin outs on a
25 pin serial port are not the same as a 9 pin port. When the serial port is configured to “No Flow Control”, only
Transmit and Ground connections are required. Request to Send and Clear to Send connections will need to be
connected only if other serial flow control types are selected.
