Abstract

PURPOSE:To automatically perform a series of tests, by repetitively transmitting the test data only with the switch turned on first, through the preparation of data for maintenance test in advance in the memories in the terminal unit. CONSTITUTION:The test pattern 41 and the program to perform maintenance test are stored in the memories of the terminal unit and the control unit 5 starts the maintenance test by turning on the switch 8. The control unit 5 reads out the program sequentially from the memory, the test pattern is read out according to the program, it is read out at the transmission buffer 6, and data are received from the reception buffer 7. This data is displayed on the display section 9. The control section 5 compares the transmission code with the reception code. If the result is different, since the next data for the maintenance test is not read out from the test pattern section 41, the display on the display section 9 is stopped, allowing the personnel to detect the presence of failure.
