The SimStack Synchro Expansion Board provides a direct digital interface to both Synchros and Resolvers. Up to two boards can be stacked on a SimStack Foundation Board or other SimStack Expansion Boards. Each board provides 4 Rx channels and 2 Tx channels, configurable for standard synchro voltages and frequencies, giving very broad support for Synchro and Resolver hardware. It reads synchro and resolver positions and drives position indicators such as rudder repeaters and trim gauges.
