26、GRADE AND TEST PROGRAM 1.Outline of test program The test program is a separate and individual application from the regular program. (Not provided with this program) The test program is provided in a file titled “diag.bin”. The test program is used by connecting the SERIAL-1 terminal of the SREV1 an

27、d the RS232C terminal on an IBM-compatible PC using a DSUB9p-miniDIN8p cable. The terminal software “TeraTerm” is required when using on an IBM- compatible PC. “TeraTerm” can be downloaded from the URL shown below. http:/www.vector.co.jp/authors/VA002416/teraterm.html (The address may be changed in

28、future.) 2.Preparations for inspection *1 Use an IBM-compatible PC that has a COM port. The settings for the COM port are: 8bit, Non-Parity, 1 Stop bit, No Flow Control. *2 Refer to the items relating to the details of individual inspections (MY8) for information about the loop back of the MY8 card.

29、 *3 This the CD-ROM disc included in the package with the product. *4 Store the test program “diag.bin” in the PC ATA card for the inspection. Dowload “diag.bin” from the YSISS home page. 3.Starting the test program Turn on the power and after the normal application has started, start the test progr

30、am using the PC card with the test program in it. Once the test program has been started, the following will appear on the “TeraTerm” terminal software. 4.Operating the test program The various tests in the test program are started by entering them in the command line of the “TeraTerm” terminal soft

31、ware. As a result, the following will appear on the “TeraTerm” terminal software. 5.Test items 5-1. serv, total check The inspection of the overall assembly is started by entering “serv” from the terminal. This will start the inspection and the progress status of the inspection for each item will be

32、 displayed on the terminal. The inspection is completed. If all the items are OK, the following is displayed. If there were items that were NG, the following list will be displayed. 5-2.
