The ChuoSeiki QT-series controllers connect to PC via the RS232 interface. It does not require any special driver to run. However, if you connect the controller via a device such as a USB-RS232 converter, be sure to install its driver.

The ChuoSeiki_QT adapters can control one or more QT-controllers: you can register multi adapters in Hardware Configuration Wizard with different serial ports, and each device adapter connects to one controller using one serial port. Exception: the 3-axis controllers can be driven by two device adapters (one for AB axis, the other for C axis), which are registered at one same serial port.

To download the QT-series controller’s user manual, please follow this link 1, click on the controller and then download the manual under the Product information bar.

Device Adapter Initialization

The “ChuoSeiki QT 2-Axis||XY stages” requests to register the Serial port and Serial port settings.

The “ChuoSeiki QT 1-Axis||Z stage” requests to register the Serial port, Serial port settings, and Axis name (or stage channel).

Register the correct serial port that connects to the corresponding QT controller. If using 3-axis controller, the above two device adapters should be registered to one single serial port (see Note on Axis name).

Please customize your stage settings using Group and Preset in Micro-Manager. Or you can load the settings from a saved .cfg file.

’'’Axis Name Registration’’’

The “ChuoSeiki QT 2-Axis” supports the 2-axis controllers or control AB channels of the 3-axis controllers. In this device adapter, the two stages names are fixed as “A” and “B”, corresponding to the controller’s A&B channels. It uses the functions that control two axes at the same time.

The “ChuoSeiki QT 1-Axis” supports the 1-axis controller or control one channel of the 2-axis/3-axis controllers. The axis name (default is “A”) can be re-defined in the device adapter as “A” or “B” or “C”, corresponding to the controller’s A or B or C channels.

To control a 3-axis controller, you need to register one “ChuoSeiki QT 2-Axis” for its A&B channels and one “ChuoSeiki QT 1-Axis” for its C channel. The two device adapters must be registered with the same Serial port, which is connected to the 3-axis controller. And remember to change the axis name to “C” when initializing the “ChuoSeiki QT 1-Axis”.
