Abstract
A terminal device for a multiplexed data transmission system has a decoder matrix having plural groups of function setting inputs for selecting plural types of functions such as interface, operation modes and other. One group of the function setting inputs are preferably address designating signals which are utilized for determining the interface. The other group of the function setting inputs determines various additional functions such as, for example, enabling/disabling of fail-safe function and automatic transmission function. Selection with the aid of the matrix allows selection of a large number of functions with a small number of input signals. Utilization of the address signals to this end allows the number of terminal pins to be decreased to a minimum.
