Testing data processing equipment - inputting known data into test appts. which produces test data, selectively sending test data over network to second test appts., which determines whether test data corresponds to expected value

摘要

The test system for mains equipment in an information processing system has a transmitter and a receiver. The transmitter has a control mode memory (51), transmitter memory (52), transmission controller (53), transmission length controller (54), detector (55), validity signal generator (56) and transmission end signal generator (57). Data is entered and stored in the first unit and is selectively transmitted to the second for checking. If correct, an acknowledgement is produced. ADVANTAGE - Simplified checking of mains equipment.
