Schematics and desciption
SPI INPUT allows to connect with the IOFireBug Engine or with previous expansion module. SPI OUTPUT allows to connect following expansion module. Closed jumper P5 defines that current Wagon 16I is the last connected module in IOFireBug Engine configuration (in other words, there is no following expansion module connected to SPI OUTPUT).
LEDs are signalizing state of each Binary input.
P3 jumper indicates, whether expander module is powered via SPI bus, or via external power supply (EXT_PWR). D1 LED indicates sufficient power delivery.
