This chapter provides an overview of the terminal’s hardware and
connectors, operating features, and site requirements.
You can use the terminal to:
•   Connect to an Ethernet network through the terminal’s ThinWire
    port.
•   Connect directly to a computer through one of the terminal’s two
    serial ports, like a traditional terminal.
•   Display multiple video terminal (VTE) windows and applications over
    both the Ethernet and serial lines at the same time.
•   Interact over an Ethernet network with multiple VTE window,
    DECwindows, and X window applications running under the VMS,
    ULTRIX, or UNIX operating system.
•   Support the local area terminal (LAT) protocol for VMS systems
    and the transmission control protocol/Internet protocol (TCP/IP) for
    ULTRIX and UNIX systems.

NOTE
To identify the terminal’s hardware configuration, see Section 3.1.

Memory
The terminal has a memory capacity of 4 megabytes. The base system
has 2 megabytes of RAM memory—1 megabyte of RAM on the system
logic board and a 1-megabyte SIMM card on the controller board (a RAM
controller board or image board).
SIMM stands for single in-line memory module. The controller board has
slots for three 1-megabyte SIMM cards.

1.1.2 Monitor
The terminal uses either a monochrome monitor (VR150, VR262, VR315,
or VR319) or a VRE01 EL flat-panel display. For more information, see
the service guide for each unit (Appendix B).

Monitor Selection Switch
Before power-up, make sure the monitor selection switch on the rear of
the system box is set to match the monitor. To find the monitor’s model
number, check the labels on the rear of the monitor.

NOTE
The terminal searches for the monitor selection switch position
only during the power-up sequence.

                                                 Overview of the Terminal 7



1.1.3 Keyboard
The terminal uses the LK400 series keyboard. It has four groups of keys,
two LED indicators, and two audible indicators—a keyclick and bell.
The LK401-XX is the standard version, and the LK402-XX is the word
processing version.

1.1.4 Mouse
The mouse is a three-button pointing device. The mouse lets you choose
items from screen menus or move the cursor to different points on the
screen.

1.2 Operating Features
This section briefly describes terminal sessions, network protocols, and
how to control feature settings on the terminal.

1.2.1 X Window Sessions and Video Terminal Sessions
The terminal lets you open two types of sessions on host computers:
Video Terminal Session
The terminal has a video terminal (VTE) window that lets you log into a
host as you would on a conventional video terminal. The terminal’s VTE
window works like Digital’s VT320 terminal.
X Window Session
The terminal lets you open X window sessions. To run an X window
session, you log into a host and use that host’s X window software.
You can open one X window session and several VTE sessions at the
same time. Within the X window session, you can run multiple X window
clients. Each X window client and VTE session appears in a separate
window.

1.2.2 Network Communication Protocols
You can use the terminal with the VMS, ULTRIX, or UNIX operating
systems. You can run video terminal sessions and X window sessions on
any of these operating systems.
For VMS systems:  The local area transport (LAT) protocol is the
communication protocol.
8 Overview of the Terminal



For ULTRIX and UNIX systems:  The transmission control protocol/Internet
protocol (TCP/IP) is the communication protocol. The terminal can use the
TCP/IP TELNET or LAT communication protocols to make video terminal
connections to UNIX and ULTRIX-based host systems in a wide-area
network.

1.2.3 Customizing the Terminal
The terminal has a Terminal Manager window with a Customize menu
that lets users view and change the settings of the terminal’s operating
features. The terminal stores feature settings in nonvolatile RAM (NVR)
memory. NVR retains the settings when the terminal is turned off, so
the terminal can restore the settings when power is turned on again. The
terminal can also restore factory-default settings from program memory
(ROM).
Before you start a session, make sure you have the font path, group code,
and specific addresses in use (Section 5.1).

1.2.4 Overriding Passwords
Performing a Secure Reset allows you to override saved passwords.
You may need to perform a secure reset if a user locks the terminal’s
customize dialog boxes, then forgets the customize security password.
When you perform a secure reset from the Session pull-down menu, the
terminal resets all customized settings to their factory defaults, except the
Secure Reset Count.
Each time you perform a secure reset, the secure reset count in the
Terminal Manager window increases by one.
To perform a secure reset, see Section 5.5.

1.3 Site Requirements
The terminal requires certain system software and network hardware to
operate. The system manager must ensure these requirements are met.
An appendix in the terminal’s Installing and Using . . . guide describes
the required system management tasks for the terminal.

Network Hardware Support
The terminal requires one of the following physical connections to connect
to a host computer system:
                                                        Overview of the Terminal 9



ThinWire         Lets the terminal operate with X window applications and
connector        multiple video terminal (VTE) sessions, using either the LAT
                 or TCP/IP network protocol. You must use the ThinWire connector
                 to operate with X window or DECwindows software.
Serial           Lets the terminal connect to a single host or terminal server as a
line             traditional video terminal.

System Software Support
The following table summarizes the system resources needed to open X
window sessions or video terminal (VTE) sessions:

Testing


This chapter describes how to:
•    Run the terminal’s built-in self-tests and menu-driven diagnostic tests.
•    Display video alignment patterns on the monitor.
•    Run remote diagnostic tests on the terminal over the network.
•    Test the LAT.
•    Test TELNET and network hardware on UNIX and ULTRIX systems.
To test the monitor, see the monitor’s service guide.

2.1 Terminal Self-Tests
The terminal has a series of self-tests to help you isolate failures to faulty
field replaceable units (FRUs). You can run self-tests in three ways.
•    Automatically during power-up
•    Using menu-driven diagnostics
•    Using remote diagnostics on the network
The terminal automatically performs basic self-tests during power-up.
You can run more extensive self-tests by using the terminal’s Diagnostics
dialog box and connecting loopback connectors to specific ports. Remote
diagnostics let you test the terminal from a remote host.

NOTE
Running the menu-driven diagnostic tests resets the terminal and
quits all session activity.

If a test finds an error:
1. Record the error code.
2. Find the error code and suggested solution in Table 3–1.
3. Repeat the tests in this chapter to ensure the terminal operates
   correctly.
The terminal will not service any interrupts or commands, except as
necessary to perform testing.

2.1.1 Successful Power-Up Self-Tests
Power-up self-tests run each time you turn on the power switch on the
system box. There are two levels of power-up self-tests —level 0 and
level 1. Level 0 tests run first, followed by level 1 tests. Failure of some
power-up tests may prevent the terminals from running.

Level 0 Testing
When you turn on the terminal, level 0 testing begins. When level 0
testing completes successfully (within 5 seconds), the operating system
starts and level 1 testing begins automatically.
Table 2–1 lists the eight level 0 tests.

Table 2–1 Level 0 Tests
Simple CPU test                    Video control register test
ROM checksum test                  I/O data path test
RAM test                           Illegal monitor test
Interrupt test                     Ethernet port (LANCE) not reset on power-
                                   up test


Level 1 Testing
Level 1 testing begins by displaying various patterns on the screen.
Next, a pie graph display appears to indicate the progress of level 1
testing. As each test finishes, a segment of the pie fills in.
When level 1 testing completes successfully (within 25 seconds of power-
up):
•   The keyboard bell rings.
•   The keyboard LEDs turn off.
12 Testing



•   The system logic board LED turns off.
•   The pie graph is replaced by the Terminal Manager window
    (Figure 2–1). The Terminal Manager title bar displayed on your
    terminal indicates the software version running.
•   The diagnostic summary box in the window contains the message:

               All Diagnostics Passed

System Logic Board LED Power-Up Sequence
When the terminal powers up, the red LED on the system logic board
turns on. At the start of level 0 testing, the LED turns off. If level 0
completes successfully, the LED turns on again. The operating system
then performs level 1 testing. If level 1 testing is successful, the LED
turns off. The following diagram shows the complete sequence:

14 Testing



2.1.2 Menu-Driven Diagnostic Tests
Menu-driven diagnostic self-tests let you test each device again after the
power-up self-tests are complete. You can test devices individually, a few
at a time, or all together in sequence. Use menu-driven diagnostics to:
•   Perform external loopback testing.
•   Verify the terminal’s operation after making repairs.

CAUTION
Menu-driven diagnostics cancel current host connections, cause a
software reset, and write messages on the screen.

Loopback Connectors
The loopback test can check the driver and receiver hardware of the
following ports on the rear of the system box:

Port            Loopback Connector                  Part Number

Host port       6-pin loopback connector, MMJ       12-25083-01

2.1.3 Displaying Video Alignment Patterns
The terminal can display the following video alignment patterns for
adjusting the monitor display:

Screen of H’s           Fills the entire active area with uppercase letter H’s (to
                        adjust focus).
Circle Cross-hatch      Fills the screen with a crosshatch pattern and draws a
                        large circle in the middle (to show linearity and aspect
                        ratio).
All White               Displays the entire active area as white or positive video
                        (for adjusting the active area).

To choose the patterns:
Display the Session menu from the Terminal Manager window.
1. Turn on the terminal. The Terminal Manager window appears.
2. Press and hold down the Shift and Ctrl keys on the keyboard.
3. With your other hand, move the mouse until the pointer is on the
   Session menu name in the Terminal Manager’s menu bar.

    MB1 is the button on the right.
5. Release the Shift and Ctrl keys.
6. Move the mouse pointer down to the name of the desired pattern.
7. Release MB1. The chosen pattern appears.
8. Press any key on the keyboard to refresh the screen.

2.2 Running Remote Diagnostic Tests over the
    Network (VMS Systems)
The terminals have built-in support for the Ethernet maintenance
operations protocol (MOP). You can test the terminal remotely from any
host system that supports the MOP version 3.0 console carrier protocol.
VMS host software that implements the console carrier protocol includes
•   Network control protocol (NCP)
•   Local area network service application (LANSA)
The following sections describe how to test the terminal with NCP and
LANSA.
You use MOP to:
•   Verify the terminal’s connection to the network.
•   Verify that the terminal can communicate with other nodes.
•   Test the terminal from a remote console and display an error message
    with error code.

Remote Test Requirements
Reset the terminal by turning the power off and on, or by selecting Quit
from the Session pull-down menu. Make sure that:
•   The power switch on the system box is on.
•   The terminal is connected to the same Ethernet network as the
    remote console.
22 Testing



•   The terminal does not have any active work (no open windows).

2.2.1 NCP Testing
To run diagnostics on the terminal from a remote console, use the network
control protocol (NCP) as follows:
1. Enable NCP by entering one of the following commands:
    $ MCR NCP
    or
    $ RUN SYS$SYSTEM:NCP
    The NCP> prompt appears.
2. Make a logical connection between the remote console and the
   terminal, using the CONNECT VIA command. The command format
   is
    CONNECT VIA circuit-id PHYSICAL ADDRESS terminal’s_Ethernet_address

    For example:
    NCP> CONNECT VIA bna-0 PHYSICAL ADDRESS 08-00-00-34-00-7D
    To determine the circuit-id, use the following command:
    NCP> SHOW KNOWN CIRCUIT
    To determine the terminal’s_Ethernet_address, ask the user to read it
    from the Terminal Manager window.
    When you successfully connect to the terminal, the following message
    appears:
    Console connected (press CTRL/D when finished)
3. Press the Return key to display the following prompt:
    DWT>>>
    DWT stands for DECwindows terminal (VT1000, VT1200, or
    DECimage 1200).
4. Enter HELP to display the commands available.
                                                                        Testing 23

2.4.2 Using ping
You can use the UNIX ping command to verify the network hardware,
Internet protocol (IP), and ICMP layers. Tracking a single-point hardware
or software failure on the Internet network can be difficult.
The ping command sends ICMP ECHO_REQUEST packets to network
hosts. The ping command utilizes the ICMP protocol’s mandatory ECHO_
REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host
or gateway. ECHO_REQUEST datagrams have an IP and ICMP header,
followed by a destruct time value and an arbitrary number of pad bytes
to fill out the packet. The default length of a datagram length is 64 bytes,
but you can change the length with the ping command.
Entering ping host name without any options will either report host
is alive or no answer from host. Options to the ping command report
additional statistics. See your UNIX system documentation for details.

Option       Function

-d           Turn on the SO_DEBUG flag on the socket.
-l           Provide a long output that gives more statistical information.
-r           Bypass the normal routing tables and send directly to a host on
             an attached network. If the host is not on a directly attached
             network, an error is returned. You can use this option to ‘‘ping’’ a
             local host through an interface that has no route through it.
-v           Provide verbose output. This option lists other received ICMP
             packets beside ECHO_RESPONSE.

3.2 Troubleshooting by Flowchart
Figure 3–1 is a flowchart to help you diagnose and troubleshoot the
terminal’s operating problems. When you turn on the terminal:
•   The two keyboard LEDs blink only during keyboard testing or to
    report an error.
•   The system logic board LED turns on and off. To see the LED,
    look through the ventilation slits on the side of the system box
    (Section 1.1).
•   The monitor displays a pie graph representing the progress of the
    self-tests.
At the end of a successful power-up sequence:
•   The keyboard bell rings.
•   The keyboard LEDs turn off.
•   The system logic board LED turns off.
•   The pie graph is replaced by the Terminal Manager window
    (Figure 2–1)
•   The diagnostic summary box contains the message:
      All Diagnostics Passed

3.3 Troubleshooting by Error Code
If the terminal’s self-tests find an error, the terminal displays an error
message on the screen and an LED error code on the keyboard LEDs and
system logic board LED. Table 3–1 lists all error codes reported in screen
error messages, keyboard LEDs, and the system logic board LED.
To troubleshoot errors, turn the system box’s power switch off and on,
then note any screen error messages or LED error codes. Section 3.3.1
lists all screen error messages. If the screen error message is unavailable,
see Section 3.3.2 to read the LED error codes. Then find the error code
and recommended solution in Table 3–1.

23         Replace the system logic board (4.6).
24         Check the Ethernet T-connector or daisy chain for proper termination.
           Install a T-connector with two terminators (no Ethernet cable), then
           turn the system box’s power switch off and on. If the same error
           occurs, replace the system logic board (4.6).
           If error code 28 occurs after error code 24, the Ethernet is only
           partially terminated. Again, check the Ethernet T-connector or daisy
           chain for proper termination.

3.3.2 Reading LED Error Codes
The terminals report hardware failures by using the red LED on the
system logic board and the hold and lock LEDs on the keyboard. This
section describes how to interpret the LED error codes. If the screen
cannot display an error message, determine the LED error code and use
Table 3–1 to troubleshoot the error.

Level 0 LED Errors
Turn on the terminal. Level 0 testing begins. If a level 0 error occurs,
the diagnostics try to display an error message on the screen and on the
system logic board LED. Level 0 errors are not reported on the keyboard
LEDs.
                                                               Troubleshooting 43



To interpret blinking LED error codes on the system logic board:
The LED displays the two-digit decimal error code in the following
pattern:
    First digit   2-second pause           second digit   6-second pause
Each digit is represented by the corresponding number of blinks: on for
0.5 seconds and off for 0.5 seconds.
For example, if there is a ROM checksum error (error code 12), the system
logic board LED:
    Blinks one time    pauses for 2 seconds           blinks two times        pauses
    for 6 seconds   repeats the sequence.

                                   2 sec          6 sec


See Table 3–1 for a list of error codes and recommended solutions.

Level 1 LED Error Codes
After level 0 testing is complete, the operating system starts and level
1 testing starts. When a level 1 error occurs, the screen displays an
error message in the upper-left corner and testing continues. When level
1 testing is complete, the keyboard bell does not ring and diagnostics
displays the error message in three places.
•   On the screen, in the diagnostic summary box
•   On the keyboard LEDs (one time, no repeat)
•   On the system logic board LED (one time, no repeat)
To interpret blinking error codes on the keyboard LEDs:
For each two-digit error code, the first digit blinks on the hold LED and
the second digit blinks on the lock LED.
The pattern of blinks is
    First digit   2-second pause           second digit   6-second pause
Each digit is represented by the corresponding number of blinks: on for
0.5 seconds and off for 0.5 seconds.
44 Troubleshooting



For example, if there is an optional memory error (error code 13), the
keyboard LEDs display the error message as follows:
   Hold LED blinks one time            2-second pause        lock LED blinks three
   times.
Keyboard LEDs do not repeat the error code sequence.
