This CV is used to configure what functions will respond to user input on the consist address. This particular CV affects F1-F8. For each Bit which is set, that the function will respond to instructions addressed to the consist address ONLY. Each bit which is cleared indicates that the function will only respond to instructions addressed to the locomotive's individual address. F1 is controlled by bit 0; F8 by bit 7.
