<p>PURPOSE:To perform display of numbers of error check and clarification of good or not of circuit condition by counting a discrimination signal of data errors through error check function, and by displaying error count value by output at proper time. CONSTITUTION:In case transmission of data starts and transmission process is conducted, the discrimination of transmission error is performed based on the function of check. When the transmission error is repeated many times, 1 is added in order to successive error count value, and when exceeding the set retry-count value, a circuit cut-off process is carried out. In terms of display ion process of error count and retry count, when an error count display key of a KEY 12 is pushed, an error count value and retry count value stored on count in memory are outputted to a display device 14 through an I/O device 8. The display device 14 outputs to LED display device displaying lower three figures as error count value and middle two figures as retry count value.</p> |
