A multi-channel network monitoring apparatus has input connectors for network signals to be monitored and four channel processors in a rack-mountable chassisenclosure for receiving and processing a respective pair of incoming signals to produce monitoring results. Specifically, the master control unit generates adjusting ratios for the RGB color data and the display driver separately adjusts each color according to the percentage of R, G, and B in the ratio to generate a resulting pixel voltage. The method can include the steps of depositing solder on one or more chip modules, placing and interconnecting low-cost components on the chip modules, and storing the preprocessed chip modules in pallets or in a tape and reel. The security token value multiplexing platform may also generate the security token value using the algorithm.
