The new Jeti Expander Module allows the connection of up to six additional buttons, switches, or potentiometers like our stick end switches. The MSW Expander Module is installed directly on the motherboard and its output is connected to the internal PPM connector. This module is designed for all Jeti Duplex DC or DS transmitters but it is only required in the DS/DC-14 to 24 if more than two additional switches are mounted.
Installation of switches to the MSW Expander Module will require soldering by the end user.
