Introduction
The ELLB Distribution Board is part of the Thorlabs series of resonant piezo motor circuits and bare modules
for OEM applications. The resonant piezo design of these motors offers fast response times and precise
positioning, and are therefore particularly useful in scanning applications.
The high-speed digital signal processing (DSP) architecture supports a multi-drop serial communication
protocol, and a set of digital IO lines allows the user to control the movement and state manually by switching
the lines high (5V) or low (0V).
The board is designed to allow up to four elliptec resonant piezo motor devices to be controlled remotely via
PC-based software, from a single GUI panel. The software can be downloaded from
. A
compatible USB driver and source code are included in the software download package.
Connection to the host PC is via the USB interface board included with the Elliptec Evaluation Kits and power
is supplied via an external 5V power supply.
Note
The module must be powered via an external 5V power supply unit (PSU). A suitable PSU is supplied in the ELL
evaluation kits; the TPS101 T-Cube Power Supply is also compatible. For customers wanting to use a third party
PSU, the Connector on the interface board is a DC Jack connector, 6.3mm OD (GND), 2.1mm ID (+5V).
