1 Mirror Driver v1.0 The Mirror Driver v1.0 consists of two main hardware blocks. The first acts as a Data Acquisition (DAQ) board while the second is an FPGA evaluation kit which is used as a Digital Signal Processing (DSP) unit to operate a mirror. The evaluation unit is a third-party product and resources are available in The package also contains a breakout board with a cable interfacing the mirror with the hardware. The driver is compatible only with mirrors produced by Optotune Switzerland AG and allows various mode operations. These modes can be selected via USB communication with a host PC. The driver features the following: USB 2.0 serial communication to a host Simple Mode operation to control a specified mirror Pro Mode operation to control a specified mirror o Real Time (RT) SPI Mode o Analogue Mode Specifications Mechanical specifications Dimensions (L x W x H) 290 x 125 x mm Weight 445 g USB connector Type B connector Female DC Barrel Jack Socket 5.5x2.1 mm Electrical specifications Supply voltage Vcc 12 V Max output voltage per channel 15 V Max output current per channel (peak) 1 A Max output current per channel (average) 0.5 A Total power consumption (both channels at 0.5A output current) Description and Features Overview 27 Thermal specifications Storage temperature -40 to +85 C The driver breaks down into two main blocks, the DAQ board and the DSP board. The DAQ boards provides signal conditioning of the all signals transmitted by or received from the mirror and handles all digital communication between the DSP board. All DSP algorithms and firmware is implemented within an Altera FPGA. The USB communication protocol is implemented within a softcore which is synthesized in the FPGA chip. All other algorithms responsible to drive and control the mirror are synthesized in the remaining space of the FPGA. Figure 1 depicts the layout of the mirror driver. W 1 The height of the driver is measured while both boards are connected and horizontal with respect to a flat surface. The highest point taken are the heatsink components on the DAQ Board.

Therefore, connection between the interface board and the breakout board is not affected by which side the interface cable is connected. Page 2 of 7

3 Powering On/Off The driver operates with a 12V power supply. However, the driver hardware is delivered without any power supply. Specifications for the power supply are shown below: Specifications Value Units Minimum Output Voltage (Vdc) 12 Vdc Minimum Output Current (A) 4.2 A Minimum Output Power (W) 50 W DC Plug Size (A, B, C) 5.5, 2.1, 9.5 mm The hardware drive is tested with a CUI power supply with model number SDI50-12-UD-P5. The supply is available to be purchased online (Link). The size of the plug is specified by XXXX-XX-XX-P5. Figure 3 Snapshot of the recommended power supply The DAQ board is powered on, as soon as the 12V power supply is connected. As shown in Figure 1, power is transferred the DSP board from the DAQ board. In order to turn on or off the driver, the red power button needs to be pressed. USB Blaster The USB Blaster (USB Type B) port is used to upload the firmware on the FPGA that is located within the DSP board. To do so, the switch Run/Prog Switch must be in the position Prog. The necessary tools are required to download the driver s firmware are: Windows 7, 8, 10 Quartus II 64-bit Version Build /22/2015 SJ Web Edition USB Blaster driver For further instructions on downloading the firmware 2, refer to Appendix - Instruction Manuals. UART to USB The UART to USB (USB Type B) port is used to establish communication between the hardware and host computer. The hardware can be set to operate in various modes. These are: Simple Mode Pro Mode Real Time SPI Mode Analog Mode For more information regarding the communication between the host computer and the driver, please refer to the instruction manual Mirror driver operational manual (see to Appendix - Instruction Manuals). 2 The firmware binary file can only be obtained by Optotune s authorised personnel.

4 SPI/Analogue Mode When the hardware is set to be in Pro Mode, the user has access to the SPI and Analog input/output pins that are located on the DAQ Board. This datasheet illustrates the pinout of the SPI/Analog connector in order to drive the mirror in one of these two modes. For both, the corresponding connector for both SPI and analog mode is P SPI Mode Figure 4 illustrates the pinout connection when the mirror is driven via the SPI interface. Pin 12: MISO Pin 11: MOSI Pin 9: SS Pin 10: SPCLK Figure 4 Illustration of the SPI pinout on the connector P20 located on the DAQ Board. In SPI mode, the driver can be configured as a slave. The mirror can then be driven via current or OF commands via the SPI interface while receiving in real time the corresponding data. The user may select to retrieve the current or OF data regardless to the type of the reference signal. However, this needs to be set via the UART to USB communication interface while the firmware is set to be in Pro Mode. For more details in how to setup the SPI mode please refer to the instruction manual Mirror driver operational manual (see to Appendix - Instruction Manuals). 2. Analog Mode In analogue mode, the mirror can be driven via two bipolar signals for channel A and B ranging from -5 to 5 Vdc. To achieve this, the user needs to provide the following unipolar signals: Signal Description Range Label Positive of Channel A A + Negative of Channel A A 0 to 5 Vdc - Positive of Channel B B + Negative of Channel B B - To create the bipolar signal ranging from -5 to 5 volts DC for channel A the difference between A + and A - is computed. Similarly, to create the bipolar signal ranging from -5 to 5 volts DC for channel B the difference between B + and B - is computed. These computations are performed digitally. For example, if the desired signal should be -4V then A + must be set 0V and A - must be set 4V and so on. The analogue pinout connections are shown in Figure 5. Page 4 of 7
