QTM300CA USER'S GUIDE
Cloning Adapter for the QT300 family QProx™ ICs
The QTM300CA is a cloning
adapter designed to interface
between QT3xx family 8-pin
QProx sensor ICs (QT300,
QT310, QT320) and a PC or
other host device.
This adapter permits the
designer to upload settings
from a PC into the target chip.
The supplied cable allows the
adapter to plug directly into the
header strip of an E3A or E3B
eval board.
In production, the target PCB
can also have a similar
connector which allows the use
of the QTM300CA to permit the uploading of settings on a production basis. The clone
process takes under 1 second to complete.
The QTM300CA also has local eeprom memory and can be used as a stand-alone
cloning adapter once it is programmed from a PC with the desired setups.
The cloning adapter can also be used to verify the settings in target QT3xx parts once
they are programmed.
For the QT300 IC, the cloning adapter also provides the additional functionality of
interfacing to that device’s SPI port to download signal data, which can then be
observed directly on the PC in real time.
The QMT300CA is designed to be used with QT3View PC software but can also be
used with customer designed software.
1x QTM300CA
1x RS232 serial cable
1x 9V battery snap
4x Rubber feet
1x QT3View user guide
1x CD Rom with QT3View software (or download latest from the website)
You will also need: An 8 to 20V clean DC power supply (or a 9V battery), and a PC
running any recent version of Windows (98, 98SE, NT4, 2000, XP) upwards, with a
free serial port (Com 1 or Com 2).
Overview

Cloning Cable
The clone cable connects to the target board and can be connected whether or not the
target is powered or not. The cable is striped and should not be inserted backwards; the
stripe connects to pin 1 of the E3A or E3B board.
RS232 DB9 Connector
This connector provides communications between the QTM300CA and the PC. It allows
the user to upload or download setups from the cloning adapter to the target QT3xx
device.
Power Connector
This screw terminal strip is used to power the board. The voltage should be between +8
and +20 volts DC. Power should be free from switching noise and short-term fluctua-
tions for best performance. A 9V battery is ideal but make sure the battery does not
drain to below 8V or erroneous operation can occur.
Board
Details
To begin using the board right away
1. Connect the board to a PC using the RS232 serial cable (included). Make sure the
serial port is not being used by any other application or driver.
2. Connect the board to the target board’s cloning header (either E3A for QT300 or
E3B for QT310 and QT320).
3. Run QT3View on the PC (found on the supplied CD or from our website).
4. Attach the 9V battery snap or other power leads to the board’s power terminal
block.
5. Turn on the target boards power.
Note that the cloning adapter is tolerant of power sequencing; it does not matter
whether the cloning adapter or target is powered first.
