Table 1. CA16-Type Transponder Pinout
(continued)
1. Frame ground is connected to the housing and is isolated from all circuit grounds (TxDGND, TxAGND, RxDGND, RxAGND).
2. Pins labeled no connection must remain open circuits; they have internal voltages and must not be connected to V
CC
, Ground,
or any signal node.
