Ethernet Plus-16 Adapter  (260-5508)  Diagnostics       Faxback Doc. # 5161

1. To run the diagnostic program, change the directory with the diagnostic
   program, \DIAGNOSE, on the software diskette.

2. Type DIAGNOSE. Then, press ENTER.
   The Introduction Screen appears.

3. Press ENTER to access the Entry Menu.

4. Press ENTER again.
   The "Choose a Board to Diagnose" option will be highlighted.

5. Press ENTER to select this option.

  *The Board Selection Menu appears as shown in Figure 2. A list of available
   adapters is displayed for your selection.

  *If an error message appears, this indicates that either an adapter board
   is not present in the computer or is not responding properly. If two adap-
   ter boards are installed in the same machine, each board should be listed
   in the Board Selection Menu and must have a unique interrupt and I/O ad-
   dress assigned to it.

  *If only one board is displayed and you're certain there is more than one
   adapter board in the computer, the same I/O address might have been
   assigned to both boards. To fix this, turn off the computer and check the
   I/O address on all boards. Change the I/O addresses so that each board has
   a unique value. Restart the computer and rerun the diagnostic program.

6. Use the arrow keys to highlight the board you want to diagnose and press
   ENTER, or simply type the number to the left of the board (for instance,1)
   to select that board.

  *The current board parameters are displayed. These items will be described
   later. Press ENTER to access the Main Menu. If your adapter is configured
   with different parameters, the option to correct these parameters can be
   accessed from this menu.

MAIN MENU OPTIONS:

Several options appear in the Main Menu. Each is described briefly below.

Choose a Board to Diagnose:
Select this option to choose a new adapter to be diagnosed. "Starting
Diagnostics" describes how this is done.

Set Configuration:
Select this option to display the configuration information read from the
board and perform temporary configuration changes. The permanent adapter
settings are not affected.

Basic Adapter Test:
Select this option to run a diagnostic test on the selected adapter.

Initiate Test Messages:
Select this option to send messages to another node running DIAGNOSE in
Responder mode.

Respond to Test Messages:
When you select this option, the program waits for a Test Message to be
received from another node on the same network using DIAGNOSE and running
"Initiate Test Messages." All received Test Messages are echoed back to the
Initiator.

Exit to Operating System:
Select this option to exit the diagnostic program and return to MS-DOS.

SET CONFIGURATION MENU:
When you select the "Set Configuration" option, a screen like Figure 4
appears. The node address for the selected adapter appears at the top along
with its adapter type as determined by the program. Below this appears a list
of parameters and their current values. Use this option to change any of
these parameters:
--base I/O address
--IRQ interrupt
--RAM size
--RAM base address
--ROM size
--ROM base address
--network connection

To change one of the displayed parameters, use the arrow keys to highlight
that parameter, and press ENTER. A list of optional settings is displayed.
Use the arrow keys to highlight the setting you require, and press ENTER. The
new setting is now displayed.

NOTES:
1. The RAM address you select here is only for the purpose of this program.
   It has no effect on any other network software used afterward.
2. The program will not stop a user from making an invalid selection.
  *Some of the choices presented might conflict with other installed devices.
  *Make sure that the choices you select do not cause a conflict. If there is
   a conflict, restart the computer.
  *When you're finished, press F10 to save the changes you've made, or press
   ESC to exit without change.
  *The Basic Adapter Test is used to verify that the major functions of the
   adapter operate properly.
  *If any test fails, the program notifies you of the error and suggests
   actions to take to solve the problem.
  *Tests are performed on the following:
   --I/O port accessibility
   --LAN address ROM
   --on-board RAM
   --network controller registers
   --on-board ROM (if installed)
   --internal loopback
   --interrupt generation

The test has failed if:

1. An error message is displayed in a red box at the bottom of the screen.

2. The test hangs up at a certain blinking line and never completes. The
   blinking line is the test that failed.
  *If either of the two preceding conditions occurs: read the error message
   or blinking line and write it down. Then, restart the computer. Use the
   error message or blinking line to find the problem. Common problems in-
   clude:
   * failure to terminate an Ethernet network
   * hardware or software conflicts with IRQ, base I/O, or RAM address.
   * If the board fails, recheck the board settings, try a different BNC "T"
     connector and terminator, or remove other boards from the computer.
 
INITIATE/RESPOND TO TEST MESSAGES:
The "Initiate Test Messages" and "Respond to Test Messages" options are used
to verify that the network cabling is properly set up to transmit and receive
information.

The Responder echoes the messages, and the Initiator makes sure it receives
the same messages it transmitted. In order to run this test, another node on
the same network must have a Ethernet adapter, must be using DIAGNOSE, and
must have "Respond To Test Messages" running.

The best test environment consists of two computers directly cabled, but this
test can be run with any computer using a Ethernet adapter on the network.

To run the initiate/respond test, follow this procedure:
1. At the chosen computer on the network, select the "Respond to Test
   Messages" option from the Main Menu. Press ENTER. A prompt appears on the
   screen: "Waiting to Respond to Test Messages. Press any key to stop."
  *This computer is now ready to respond to test messages and is called the
   Responder.
2. At a different computer, select "Initiate Test Messages" from the Main
   Menu.
  *Press F2, and all active Responders are displayed with their network
   addresses. Use the arrow keys to select the Responder you want to test.
3. Press ENTER to begin the test.
  *The test will perform 1000 iterations after finding the first available
   Responder if a Responder has not been previously selected.

NOTE: If the test stops after sending only a few frames of data, press ENTER
again and the test will continue to the end.

If the error message "No Responder Found" is displayed, the two computers
cannot communicate across the network. Common reasons for this failure are
faulty cabling, faulty "T" connectors, or terminators that are bad. See the
"Troubleshooting" section for other suggestions.

When the test is complete, press F4 at either computer to see the test re-
sults as shown in Figure 5. This screen provides you with statistics on both
the Initiator and Responder terminals. You can tell whether the Initiator and
Responder passed by referring to this screen. If the Frames Sent field and
the Frames Received field are equal, or the difference between them is less
than 1% of the total, then the system passed.

The Show Statistics screen also provides a number of function key operations:

* To update data without clearing the counter setting, press F4.
  This automatically updates data as the test continues. To clear these
  statistics, press F6.
* To exit this test and return to the Respond Menu, press ESC.
* To change the test parameters, such as number of iterations or the test
  pattern, press F6 at either the Initiate or Respond Menu. A screen with a
  list of all test parameters appears. For most of these parameters, use your
  arrow keys to highlight the parameter you want to change, then use the
  space bar to change the setting. Each time you press the space bar, the
  value will change.
* To change the test pattern or destination address field, type in the value
  you require. When finished, press ESC to return to the Respond Menu.
* For a definition of each parameter used during this procedure, press F1 at
  the appropriate screen. A list of relevant definitions appears.
* Select the Exit option when all diagnostic procedures have been completed
  and you want to return to MS-DOS.
* For more information on how to operate the diagnostic program, refer to the
  USER.DOC file located on the software diskette.
