3.2 System Power
The RS9110‐N‐11‐21 is powered from a source in an assembled Tower System via the 3.3V supply on
the Primary Elevator Connector.
3.3 Access Header
The SPI and interrupt signals are routed to both the Primary Elevator connector and a 2x5 pin header.
This Access Header can be used to access the RS9110‐N‐11‐21 module signals for probing or for use
outside of the Tower System. The pinout is shown in Table 1.
3.4 Elevator Connections
The TWR‐WIFI‐RS2101 features two expansion card‐edge connectors that interface to Elevator boards
in a Tower system: the Primary and Secondary Elevator connectors. The Primary Elevator connector,
comprised of sides A and B, is utilized by the TWR‐WIFI‐RS2101, while the Secondary Elevator
connector only makes connections to ground (GND). Table 2 provides the pinout for the Primary
