4.4 Encoder/Hall-Effect Interface J8
The Encoder/Hall-Effect interface J8 is located on the right edge of the board. The circuit is designed to accept +3.3 V to +5
V encoder or Hall-Effect sensor inputs. Input noise filtering is supplied on the input path to the Encoder/Hall-Effect interface.
Table 4
4.5 Elevator Connections
The TWR-MC-LV3PH features two expansion card-edge connectors that interface to Elevator boards in a Tower System: the
Primary and Secondary Elevator connectors.
An “X” in the “Used” column indicates that there is a connection from the TWR-MC-LV3PH 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.
