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.
