7. LED Module Care and Replacement
F2 Module
Each F2 has 4 LED modules connected to the panel frame by magnets. Each module has a single
connector that connects to the main processing unit.
LED Lot Numbers
To ensure consistent color matching and output, replace damaged or defective modules with the same
LED lot # as the others on the panel. When combining panels to create full video wall systems (rentals,
permanent installations, etc.) it is highly recommended that the LED lot #’s on each of the panels match.
LED lot #’s can be located on the back of each module.
A and B Modules
The F2 has 2 types of modules, designed to only plug in to the Service Module from one direction. Check
the orientation of the LED LOT # label to determine whether the module is an A type (top half, connector
down) or a B type (bottom half, connector up).
Calibration Recall
Each LED module for the F2 has individual calibration data for each LED permanently saved to the flash
memory of the module. The receiver card inside the control box (or Service module) of the F2 can use that
data to ensure a uniformity of brightness across the entire panel. To upload the calibration data from a new
LED module to the Service Module of the panel, follow the instructions below.
Without a Computer
1. Unplug any signal cables and power the product off.
2. Hold the Test Button down and power the product on.
3. Continue to hold the Test Button down for 10 seconds.
4. Release the Test Button. The signal indicator will flash rapidly while it downloads the calibration
data from the module.
5. When the signal indicator stops flashing rapidly, the new module will have been matched
automatically to the rest of the panel.
With a Computer
See the Novastar Troubleshooting Guide for instructions on how to perform a calibration recall with
a computer.
The arrows on each module point towards the top of the panel when correctly installed.
