The LCU-128, is short for “Launch Control Unit – 128 Pads.” It is the next sized larger for a standard full system brain. It is a launch controller capable of individually controlling up to 128 separate pads. The controls of the LCU-128 are subdivided into 16 banks and 8 pads each. The communications from the LCU-128 to all the pad boxes run thru standard 16/3 outdoor extension cords and/or wirelessly. Functions are identical to the LCU-64. You select which bank you want to fire A thru P, then you select from between one and up to eight of the pads on that bank to ignite when you push the FIRE button. The system shows the Launch Control Officer if an igniter is good or bad but even with a false “bad” (some home-made igniters will read “no-continuity” at the LCU-128 and still work) the system will automatically “fire” every pad that is selected on any single bank of pads. The LCU-128 will only operate one bank at a time as a safety feature. If two banks are selected at the same time, the LCU-128 will send NO fire commands, period. There is a removable system power on/off key which is only removable in the off position. And there is a TEACH/VOLTS toggle switch. The TEACH switch is used for reprogramming bank/pad designations on pad-boxes. The VOLTS switch reports the voltage of a bank of pads battery thru the LCU-128 to the LCO.
