  • Page 5 Part 1. Introduction The PDQ80S1 and PDP90S1 (from now on referred to as the PSD System) are a visible to IR beam alignment solution consisting of one detector and one sensor processing hub. Up to four sensors can be connected to a single hub.
  • Page 6 USB 2.0 Port Figure 1: Four Channel Hub (PDQ80S1 Shown) The hub can be powered by connecting the device to either a PC or a USB AC power converter. Once connected to the PC, the device can be controlled with the PSD Beam Alignment Display program. If the device is powered with the USB AC power converter, it will operate in Stand-Alone Mode, and the Sensor Status LED is used to verify beam alignment.
