5250 REMOTE EMULATOR CARD

11.Run the Card’s diagnostic program before you replace the PC’s cover:

a)Plug in the monitor, keyboard, and power without replacing the PC’s cover, then turn ON the PC. (Be extremely careful while you do this.)

b)At the first DOS prompt, go to the directory where you have the 5250 Remote Emulator Card’s software stored: Type the diskette- drive letter followed by a colon and [ENTER] (if you are keeping it on a copy of the original diskette) or the hard-disk letter followed by a colon, a backslash, the subdirectory name, and [ENTER]

(if you’re keeping it on the hard drive).

c)At the next DOS prompt, run the Emulator’s diagnostic program

by typing

emdiag [ENTER]

A copyright screen appears, prompting you to press [ENTER] to continue. Then, as shown in Figure 4-3 on the next page, a diagnostic screen appears, showing the PC I/O addresses the Card supports. Use the cursor to highlight the address the DIP switch is set for, then press [ENTER].

d)If this test fails for the given address, there might be a conflict for that address that you’re not aware of. Check the address settings of the PC’s I/O components again, carefully, and try setting the Card’s DIP Switch to a different address. If the test fails for several addresses, make sure the Card is seated properly. If the test fails for all the addresses you try, the slot it’s in might be defective; reinstall the Card in a diferent slot. If all addresses still fail, you probably have a bad Card. See Section 9.3.

e)If this test is successful, the program prompts you to let it do a modem-loopback test. Go to the next step.
