If your device is not calibrated all controls will be disabled. To calibrate your device, go to “Calibration” tab. - Page 12 Figure 6. Calibration tab. Calibration procedure: In order to correctly change the output power, the software needs to know the angle of the λ/2 waveplate’s fast axis. It can be fixed in any angle with respect to the rotator. The purpose of calibration is to fix angular offset between the λ/2 waveplate and the rotator hardware zero position.

Page 18: Ethernet Protocol Description
COM-port parameters are fixed on the controller-side: Speed: 115200 baud Frame size: 8 bits Stop-bits: 1 bits Parity: none Flow control: none Byte receive timeout: 400 ms *USB port simulates COM port on a PC. All the commands are the same for all communication protocols (see “6.4 Controller Commands”). - Page 19 Both controller and PC have an IO buffer. Received commands and command data are processed once and then removed from buffer. Each command consists of 6-byte identifier and optionally a data section followed by its 2-byte CRC. Data can be transmitted in both directions, from PC to the controller and vice versa.
