IU1800-500 HD Video Converter and Splitter

The IU1800-500 is a Video Conversion unit that consists of an Input Equaliser, a Frame Rate Converter and output Driver. The unit accepts four independent HD-SDI signals and outputs four identical HD-SDI signals.

The IU1800-500 is a configurable HD video converter and scaler that supports conversion of Progressive to Interlaced HD signal formats which allow HD Progressive imagery to be displayed on MFD’s and ancillary displays that only accept Interlaced HD sources.

Due to its compact design, the IU1800-500 can be installed in virtually any interior location on an aircraft.

The unit can upscale a video input and convert the original source format to meet specific video frame rates, for specific user requirements.

The IU1800-500 is autonomous, and once power is supplied the unit, is fully functional. The IU1800-500 is equipped with built-in supervisory monitoring of the unit’s temperature and power and will illuminate a red LED if a fault is detected. All indication LED’s are fully NVG compliant.

The unit is designed to meet and have been tested and qualified to the environmental conditions specified in RTCA/DO-160G including Lightning Induced Transients.

All of the unit’s electronics are designed and manufactured by RDDS with an emphasis on through-life support, reliability and ruggedness.
