PURPOSE: To make it possible to test a testing unit independently without an additional accessory unit, by communicating first data from a classification means as well as transmission data from transmission data making means. CONSTITUTION: When data in LAN transmitted from a unit 1 is received, a check is made under first testing conditions previously set. When the testing unit is conformable, the testing data is fetched. After data is received by a LAN receiving processing unit 11 under second testing conditions (A2), the data classified into first data in receiving and second data in reply as an answer signal is generated by a receiving data classification/check processing unit 13. Then, a transmission data forming unit 14 generates transmission data obtained from the second data under third test conditions (A3). A transmission request processing unit 15 stores transmission data in a transmission buffer 16, and a LAN transmission processing unit 17 transmits the transmission data formed as a LAN signal under fourth test conditions. As a result, a testing unit can be tested independently without an additional accessory unit. |
