Overview
The E297s board is designed for rapid
development and programming of the
QTM2000 module for capacitance-
based sensing systems. It includes all
the circuitry required to make a fully
functioning sensor system and to allow
programming of the QTM2000. This
board has a full-duplex serial interface
that allows connection to a PC for
function control and data viewing. This
board is fully compatible with QTWin-
view software.
The QTM2000 module uses the
QT9701B2 IC as its basis; a datasheet
for this part is available from
Quantum’s web site.
To begin using the board right away:
1. Insert a QTM2000 module into the ZIF socket, being certain to align the module so
2. Connect a switchable source of +8 to +20VDC to the screw terminal block. This may
3. Connect the RS232 serial connector to a PC using a 'straight-through' extender type
4. Plug in the thin coax cable to the connector labeled 'SIGNAL' on the board; connect
5. Run QTWinview on the PC. Click on FILE | LOAD GRID and open the file
6. Click on COMM | SETUP and make sure the PC serial port matches the one you are
7. Apply power to the board. One or both LEDs will illuminate or flash.
8. Click on 'GO ONLINE' at the bottom of the QTWinView window.
9. Click on 'GRAB CURRENT' at the bottom of the QTWinView window. Cells in the
10. Click on 'POLL QPROX' at the bottom of the QTWinView window to view the actual
11. Push the BG button on the E297S to calibrate the QTM2000 and bring the signal into
If the board will not communicate with the PC, check the Baud rate and Comm port
settings, your cable connections, and the power to the E297s. If the board will still not
communicate, see the Trouble Shooting section of this document.
