QTM300CA USER'S GUIDE

Cloning Adapter for the QT3xx family of QProx™ ICs

The QTM300CA is a

cloning adapter designed

to interface between any

QT3xx 8-pin sensor IC

(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 or to read the

settings inside a chip. The

supplied cable allows the

board to plug directly into

both the E3A and E3B

eval boards.

For production use, the

target PCB can have a similar connector which allows the QTM300CA to upload

settings on a mass basis. The cloning process takes under 1 second to complete.

The QTM300CA’s eeprom memory permits the board to be used as a stand-alone

cloning adapter once it is programmed from a PC with the desired setups. An onboard

socket also allows the user to program QT3xx parts individually. The QTM300CA can

also be used to read back and verify the settings in QT3xx parts.

For the QT300 continuous IC, this 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 using QT3View software.

QT3View PC software is included, and updates can be downloaded from Quantum’s

web site.

You should find the following materials included with your QTM300CA:

 1x QTM300CA board

 1x RS232 DB-9 serial extension cable

 1x 9V battery

 1x QT3View user guide

 1x CD Rom with QT3View software (or, download latest from www.qprox.com)

You will also need: A PC running any recent version of Windows (98, 98SE, NT4,

2000, XP) upwards, with a free serial port (Com 1 or Com 2), and if desired a bench

power supply to replace the battery (9 - 15V DC) for long term use.

Overview The QTM300CA can operate in two basic modes: - PC-driven mode - Stand-alone mode In PC-driven mode, you can a. Load Setup information into it for all three part types for use in stand-alone mode, from a PC running QT3View. b. Communicate directly from the PC to the QT3xx part without disturbing the contents of the QTM300CA. c. Read back the Setups of any QT3xx device to your PC. d. View actual signal data on-screen in real time (QT300 only). e.

Figure 1 - Board Layout Board Details Power Switch Selects between the onboard battery (right) or an external power source (left). Power For external power, between +8 to +20 Volts DC. Power should be free from switching Connector noise and short-term fluctuations for best performance. A 9V battery is fine for short term use, but make sure the battery does not drain to below 8V or erroneous operation can occur. RS232 Provides communications between the QTM300CA and the PC.

Status LEDs PC Indicates if QT3View software is communicating with the QTM300CA. This LED will turn off five seconds after communications have stopped. DEV0, DEV1 Displays the chip type connected via the ribbon cable or in the onboard socket: DEV1 On On DEV0 On On Device None QT300 QT310 QT320 PROG Indicates the programming status of the target chip in Stand-alone mode. The PROG LED will light during the cloning process in Stand-alone mode.

The software will auto-recognize the type of chip connected to the QTM300CA and choose the right tab for you. If no chip is installed, the tab can be manually selected to allow data transfers with the QTM300CA’s onboard e2prom. File | Open Restores a config file saved by (File | Save).

Setup and These show and modify the available Setups for the chosen chip. Guideline Boxes Timing related values have no meaningful unit of measure unless interpreted together with the device supply voltage and Sleep Cycles. To aid in understanding the effects of these Setups, ‘Guideline’ boxes are used next to timing related Setups to give an estimate of the result in seconds. Guideline boxes cannot be modified, they only exist to inform you of the effects of the timing Setups.

Cloning Directly to a Chip You can read and clone back information to a QT3xx chip directly from your PC without involving the onboard stand-alone memory of the QTM300CA. Here’s how.... Step 1 Hook everything up: Connect the serial cable from the PC to the QTM300CA. Connect the QTM300CA’s cloning cable to the target PCB, or plug a QT3xx into the onboard socket. Power up the QTM300CA and, if necessary, the target PCB. Step 2 Start QT3View on the PC: The PC LED should come on.

Storing Setups into the QTM300CA You can save Setup information from the PC to the onboard eeprom of the QTM300CA for use in cloning of parts on a stand-alone basis. You can also read back these Setups to your PC at any time to verify them. The QTM300CA can independently store three Setup configurations, one for each part type. Here’s how..... Step 1 Hook everything up: Connect the serial cable from the PC to the QTM300CA. Power up the QTM300CA.

Clone Connector Design Rules Care must be taken when designing an onboard cloning connector. The following are a few requirements needed for a successful cloning connector design. QT320/QT310 Place the connector as close as possible to the chip. Placing the cloning connector far from the part will increase sensor load capacitance Cx and decrease sensitivity, as some of the cloning lines are also sense lines.
