5.1 Elevator Connections
The TWR-RF-SNAP features two expansion card-edge connectors that interface to Elevator boards in a
Tower System: the Primary and Secondary Elevator connectors. Table 1 provides the pinout for the
Primary and Secondary Elevator Connector. An “X” in the “Used” column indicated that there is a
connection from the TWR-MEM to that pin on the Elevator connector. An “X” in the “Jmp” column
indicates that a jumper is available that can configure or isolate the connection from the Elevator
connector.
