INTRODUCTION
The unit monitors inbound and outbound phone calls for Caller ID and Touch Tone (DTMF)
signals on two telephone lines. Phone call records are sent to a sent via a RS232 serial
interface to a computer, terminal unit, or printer. Call records are also written to an on-board
memory. The unit does not answer or initiate phone calls. It is compatible with, and does not
affect the operation of any telephone equipment attached to the telephone line including
telephone switches such as Key Systems or PBX's.
The unit is set from the factory to monitor both incoming and outgoing phone calls. It can be
set to monitor only incoming calls. It can send call records immediately after a call begins,
just after a call is completed, or both. The unit can also be set to report additional detail
information on each call including Ring Signal, Off Hook, On Hook, and Hook Flash.
Up to 248 call records can be stored in non-volatile memory. Call records can be downloaded
and erased using simple commands. The memory "rolls over" such that only the last 248 call
records are retained.
Setup toggles are case sensitive letters that are stored internally to determine how the unit
operates. Upper case (capital) letters turn off options while lower case (small) letters turn on
options. Operating commands are available to list the setup toggles, set the time clock, and
control the memory.

Technical specifications, manufacture's information, and warranty statement
Figure 1 shows the front and back views of the unit. Each channel lights shows the status of
the telephone line. The channel light should remain on when the phone line is not in use (On
Hook) and should pulse every second when the phone is in use (Off Hook). The channel
lights will also follow ring signals and touch tones dialed. The power light will remain on
except when the unit is transmitting data.
Power, serial, and telephone jacks are located on the back of the unit. Connect the power
supply and serial cable supplied. Telephone lines do not have to be connected in order to
establish communication between the unit and the computer (see pages 6 or 7). The two
telephone jacks are designed for a 4-wire (RJ14) type modular connection. This means a
phone cord that contains 2 active phone lines should be connected. If you are not completely
familiar with the above terminology, please refer to “Section III - Telephone Connections” on
page 28.
Do not attach 2 phone cords that carry a different phone lines to each jack.
One of the jacks should be used for an input cord and the other for an output cord.

4 conductor jacks connect
2 phones lines carried by
1 phone cord. One side of
jack connects to wall,
other side to telephone

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. If the internal
jumpers reconfigured to current detection mode, it can also operate on trunk lines (or “ground
start” lines). It 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. Also, the unit can monitor outbound calls when 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 configured to detect On/Off Hook by means of current flow through
the device (see page 40). For additional information on voltage vs. current detection please
refer to Appendix A on page 44.
Caller ID Capture Outbound Calls On/Off Hook Detect
Standard Local Loop (1FB) Yes Yes Voltage or Current
Analog Centrex Yes Yes Voltage or Current
Ground Start (Trunk) Yes Yes Current Only
ISDN Interface w/ Analog

ates analog Caller ID
Yes, through
analog ports only

Switch Analog Extensions No Yes Current Only
Switch Digital Extensions Not Compatible Not Compatible Not Compatible
ISDN, T1, Digital Centrex Not Compatible Not Compatible Not Compatible
In order to capture Caller ID, an analog Caller ID signal must 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. This unit will not operate if directly connected to digital phone lines or digital
extensions.
