5 Tower Elevator Connections
The TWR-MCF51JG features two expansion card-edge connectors that interface to the Primary and
Secondary Elevator boards in a Tower system. The Primary Connector (comprised of sides A and B) is
utilized by the TWR-MCF51JG while the Secondary Connector (comprised of sides C and D) only makes
connections to the GND pins. Table 7 provides the pinout for the Primary Connector. (NC = No
Connection)
