Selects between the onboard battery (right) or an external power source (left).

For external power, between +8 to +20 Volts DC. Power should be free from switching 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.

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. The cable to the PC should be an ‘extension’ type (wired 1:1), included.

Connects to the target board and can be connected whether or not the target is powered. The cable has a stripe on one side; care should be taken not to reverse this cable. This stripe aligns with pin 1 (white square) of the E3A or E3B board header.

The QTM300CA can be used to program QT3xx chips onboard. The board can accommodate either a ZIF socket or a SMT socket (when used with appropriate adapters, not included - see Figure 1 above and ZIF Info, Page 11).

In Stand-alone mode, once the chip to be programmed is inserted, the QTM300CA will detect the chip part number and display it on the ‘DEV0 and DEV1’ LEDs (see below).

If a QT3xx chip has been auto-detected, this button will clone Setups data from the QTM300CA to the chip. The ‘PROG’ LED (see next section) indicates the programming result. The QTM300CA can store three sources of data, one for each part type. The correct source will be used to program the detected part.
