TWR-56F8400 User’s Manual Page 20 of 35Appendix A – Tower Elevator Connector Pin FunctionsTable 7 provides the pin out for the Primary Elevator Connector. An “X” in the “Used” columnindicates that there is a connection from the TWR-56F8400 board to that pin on the Elevatorconnector. An “X” in the “Jmp” column indicates that a jumper is available that can isolate theonboard circuitry from the Elevator connector. An “X” in the “Jmp” column indicates that a jumper isavailable that can isolate part of the onboard circuitry from the Elevator connector.The function listed in the “Usage” column is the function(s) that the pin is expected to be programmedto provide when used with the Tower system. All of the MC56F84789 pins (except power) havemultiple functions. Not all of the possible functions are shown.Note that all analog pins (ANAn or ANBn) have a low pass filter to ground consisting of a 100 ohmresistor and a 2200 pf capacitor. This is to protect the analog inputs of the DSC from a static dischargeat one of the connectors. See schematic sheets 6 and 7 in Appendix B – TWR-56F8400 BoardSchematic.Table 7.
