Wavefront Sensor
4.4 Connecting the Wavefront Sensor
Note
Do not connect the Wavefront Sensor to the PC prior to software installation!
Install the Wavefront Sensor application software and USB drivers (all in one package) on your
PC prior to connecting the Wavefront Sensor to your PC. Then connect the sensor head by fol-
lowing the instructions for the wavefront sensor head type, given below.
WFS20
1. Connect the WFS20 sensor head to the control box using the included PoCL cable.
2. Connect the power supply to the mains supply.
3. Connect the power supply to the control box.
4. Connect the USB port of the control box to computer using the included USB2.0 cable.
5. The software will automatically recognize the wavefront sensor.
To disconnect the WFS, follow the above steps in the reverse order!
Attention
Do not connect or disconnect the Power over Camera Link (PoCL) cable while power is
supplied to the control box! This will damage the electronics!
Note
The Wavefront Sensor will not work when connected to a USB 1.1 port!
WFS30 or WFS40
Connect the Wavefront Sensor to a USB 3.0 port of your computer. Use only the cable included
with the Wavefront Sensor shipment. The software will automatically recognize the WFS.
Note
When connecting the wavefront sensor head to the PC for the first time, Windows may show an
erroneous error-message:
"The device driver software was not installed correctly"
In most cases, this error message can be ignored and you can proceed to use the WFS. In
case you can not access the WFS through the software, please see the section
Troubleshoot-
ing in the full manual, downloaded from the software website.
Attention
·
Do not use cables other than the supplies USB cable because other cables may not sup-
port the high-speed USB transfer rate and high-power requirements of the WFS. Cables
with insufficient performance may cause transmission errors and improper instrument op-
eration!
·
Be sure to connect the supplied USB cable to a high speed USB 3.0 port. Connecting the
WFS heads WFS30 and WFS40 to a USB 2.0 port leads to a degradation of performance
(slower data transfer). The Wavefront Sensor will not work when connected to a USB 1.1
port!
·
WFS40 sensor head types consume up to 580 mA via USB. As standard USB 2.0 ports
deliver only a maximum current of 500 mA, these WFS types may not be operable via a
USB 2.0 port at all.
After connecting the instrument to the PC, the operating system recognizes the connected in-
strument, installs the appropriate driver software, and identifies the connected hardware.
