Connecting the unit
Step 1 –Unpack the GaneData USB package and check the contents with those
on page 1.
Step 2 –Connect the GaneData USB device to the computer using the USB cable
and connect the telephone line with GaneData USB device by provided cable.
Step 3 –Install the drivers for the unit. This is outlined in the following section.

Step 1: Open “device manager” under hardware Tab by right clicking on my
computer and then properties

Step 2 –Open the GaneData USB driver Folder and copy the address
from address bar of the folder:
e.g. D:\Drivers\GaneData USB Driver
Step 3 – Right click on “GaneData USB” shown under “Ports (COM &
LPT)” and click “Update Driver Software” button.
Step 4 – Select “Install from a list of specific location” then select or paste
the copied location of the downloaded drivers or the location of the driver
CD and then click “Next”.

Step 6 –Once the driver has been installed you will then need to repeat steps 3 to
6 for the “USB Serial Port”.
Step 5 –Windows will then warn you that it cannot verify the publisher of this driver
software. Click “Install the driver software anyway”.

General
GaneData USB is a device for decoding the Caller ID from the telephone line and
presenting it on a virtual serial Port on a PC.
With the right PC application the GaneData USB allows to record the following
details from a telephone call.
Caller ID information and Time & date of call
GaneData USB is unable to provide information about answering a call and
outgoing calls.
The following information describes the operation of the device along with details
of presentation of the data. This will allow GaneData USB Device software
developers to provide turn-key applications. Information regarding Caller ID is
also presented.
Specification
There are four major types of Caller ID to be found around the World. They can
be categorized as follows:
•US FSK: Ring, FSK data, Ring.
•ETSI FSK: Ring, FSK data, Ring.
•BT FSK: Line reversal, FSK data, Ring
•ETSI DTMF: Ring, DTMF data, Ring

Specification Continued:
By detecting ring OR line reversal signal as the start of the Caller ID sequence, the
GaneData USB device is able to work with all of the FSK data formats i.e. US FSK,
ETSI FSK and BT FSK.
There are minor differences between the FSK types as to how the data is formatted.
However, GaneData USB device does not try to interpret the data received from PSTN.
It checks the data for errors by using the checksum and passes the received data to PC
without any modification. In this way, any differences between the FSK types can be
resolved with the application running on the PC.
The GaneData USB detects and reports on only the Caller ID information on the
telephone line.
Hardware:
The GaneData USB is powered from the USB interface. When the unit is connected to
the USB port the one of the Red LED turns‘ON’ to indicate that the unit has been turned
on. While receiving a call, the Green LED blinks to indicate information being received
and sent to the USB. This Green LED will also blink when information is written to the
virtual COM port. This can be a useful diagnostic, e.g. to check that the service has
actually been switched on by BT, or that the telephone line is connected.
Specification of Data:
The serial data is presented at a baud rate of 1200, with 1 start and 1 stop bit. The data
is sent whenever there is activity on the telephone line. The GaneData USB does not
receive any data from the PC.

Caller ID Structure:
Within the FSK data types, there are two types of message structures. The one used
in Europe (including the UK) and most of the US is known as the Multiple Data
Message Format (MDMF) and is described below. The other message structure is
known as the Single Data Message Format (SDMF). It is only used in some parts of
the US. The MDMF Caller ID message typically consists of the following:
•1 Byte
Message type (Always
Sent)
•1 byte (all the bytes to follow, except the Checksum)
Message length
•1 Byte
Parameter type (At
Least 1 Sent)
•1 Byte (=X)
Parameter length
•X Bytes
Parameter
•1 byte
Parameter type
•1 byte (= y)
Parameter length
•y bytes (actual displayable information)
Parameter
•1 byte (used for checking for any errors)
Check Sum

Message type
For valid Caller ID this will in most instances be 80H. For message waiting 82H is sent but
this is little used. In general, if 80H is not received from the serial port, the whole Caller ID
string can be discarded.
Message length
This is a total of all the bytes to follow, except the Checksum. It is useful as an error
check.
Parameters
This is the actual payload of the Caller ID data. There are a number ofparameters that are
defined. The most important ones are outlined below.Anyother parameters received need
to be accounted for, but then can be ignored.
Time & Date=01H
This parameter is always sent with a length of 8 and is structured as follows. (This can be
assumed to be "real time" accurate to within 1minute and can be used to update the PC
clock if required.)
•First 2 bytes Month
•Next 2 bytes Day
•Next 2 bytes Hours
•Last 2 bytes Minutes
Calling Line Number=02H
The maximum length of the number sent is 18 characters. Spaces and/or dashes are sent
as delimiters.

Reason for absence of number=04H
This parameter is set as follows:
WITHHELD=50H (PASCII)
UNAVAILABLE=4FH (O ASCII)
Calling Line Name=07H
This parameter was initially designed to send the caller’s name. However,
international calls have "INTERNATIONAL" in this field, and some payphone calls
have "PAYPHONE" in this field.
Call Type=11H
This parameter is only sent for ETSI FSK and BT FSK. In general it can be ignored.
There are three call types defined:
Voice call 01H
Ring back when free 02H
Message waiting 81H
