2 The element configurations are identical, as well as the internal elec-tronic circuits. Whereas the PYD 1778 represents the lower-cost version with a small window, the PYD 1798 is provided as the superior type in terms of White Light Immunity (WLI) performance and field of view. The output signals are communicated in one 15-bit digital bit stream output via a single wire direct link connection to a suitable host dimensions in XLTS_CAT Infrared 193/22/11 10:49 AM
