ABSTRACT:
A master terminal system for a star network is provided wherein a master station transmits a continuous signal to a plurality of terminal stations, and each terminal station transmits a signal to the master station according to a time-division multiple access procedure. A deviation of the signal originated by a terminal station from a proper position can be measured even by an unskilled person, without the need to use a measuring instrument such as a synchroscope. When a signal is supplied from a particular terminal station to the time slot specified by a time slot setting switch, a unique word detecting circuit detects a unique word for a predetermined time period at least longer than the time width of the unique word which is to be detected in this time slot. If input of the unique word is detected within the predetermined time period, a display section shows the detection of the unique word, thus making it possible to ascertain that the signal from the particular terminal station has been multiplexed at the proper position. The predetermined time period can be set as desired so that it may be narrowed stepwise about the proper position of the unique word. In this case, the amount of deviation of the unique word, contained in the signal originated by the particular terminal station, from the proper position can be obtained.
