LSS−100P Installation & Operation Manual

Features

Luminance Measurement – Uses a precision detector with a photopic spectral response.

Chromaticity Measurement – Uses a precision RGB sensor and calculates XYZ, xy, and CCT.

SPL Measurement – Uses a DSP generated C-weighting filter and RMS detector for accurate
results regardless of signal waveform or crest factor.

IR Measurement – Measures relative IR illumination of screen to detect issues with IR emitters
used for hearing impaired audio, visually impaired audio, or closed captions.

Temperature Measurement – Includes an internal temperature sensor that can be used to
approximate auditorium temperature and track changes.

Web Interface – Displays live measured data along with user defined reference values.

TCP Command Interpreter – Accepts commands over Ethernet to log data, send current
measurement, start a measurement script, etc.

Command Scripting – An unlimited number of user scripts (up to a total of 64,530 characters)
may be defined. Scripting allows a test sequence to be started by sending only one command to
the LSS-100P.

Script Start with Contact Closure – Terminals are provided on the USB power interface board to
start three individual scripts with contact closures. This allows digital cinema servers without
provision for user defined TCP command strings to start LSS-100P scripts.

Logging with Limit Checking and Graph Generation – The LSS-100P can capture measurements
to a log. The log shows the measurement in red if it is outside user defined limits. The log can be
downloaded as a CSV file for analysis in a spreadsheet. The LSS-100P generates graphs of logged
data showing trends of the measured data along with limit lines.

Web Services Posting – The LSS-100P can post log data to one or more HTTP or HTTPS servers.
Log data is sent as XML for simple parsing into a database for report generation.

Power Over Ethernet – The LSS-100P can be powered by a POE enabled Ethernet switch or
power injector. Use of POE simplifies installation since fewer wires need to be run. The LSS-100P
is an IEEE 802.3af class 1 powered device. It may be powered by “active” (power sources that
use the POE signature) or “passive” (power sources that do not use the standard POE signature)
48V POE injectors. The LSS-100P consumes less than 1.5W.

USB Power – The LSS-100P can be powered by the supplied USB power supply. This is a low cost
alternative to POE.
