Senal Lmk and Vldeo Cables

~ The procedures requn'ed for the installation of the senal link and video

cables will vary from system to system, and hence are not detailed here.
- However, irrespective of the precise system, the precautions regarding the
use and routing of the serial link cablesnoted below must be observed.
Note

ngnallmg over the serial link cables is in RS232-C format.
RS232-C is intended for local communication. In general,
the communication devices can become non-operational or be
~damaged if the total cable length exceeds 100metres (300 feet).
The cable should not be run outdoors, and the low voltage data

- wiring must be separated from ac power wiring. The installation
or sites may require additional devices to correct problems in
communication.

2.2.3 Remote interface Box

The remote interface box may be desktop, floor or wall mounted. Proceed
as detailed in the appropriate paragraph below.

This chapter contains a descrtptron of the dtagnostlc phtlosophy as used

in the VSV21 product. Detailed instructions for running these diagnostics,
and the error messages generated are contamedin Chapter 4,

MAINTENANCE STRATEGY

3.2.1

Preventatlve Maintenance

No preventattve maintenance is planned for thts optton However if you
are servicing the host system, examine theoption for loose connectors
and damaged cables

3.2.2

Corrective Maintenance -

- Corrective maintenance is based on finding and replacing
the defective
field-replaceable unit (FRU). The device is not user-serviceable.

3 3 DIAGNOSTICS OVERVIEW

- The dtagnosttcs programs promded are 1ntended to fmd fauIty FRUs
They are not intended to find faulty parts smaller than an FRU.

Some of the diagnostics need loopback test connectors The penpheral

concentrator kit includes loopback connectors to test as far as the remote
end of the data link cable. The VSV21 loopback kit must be taken on-site
or obtained from Digital Equipment, as appropriate (VSVZl AJ).
The FRUs identified by the diagnostics are:

The M7656 VSV21-AA module

The Power-Up Self-Test (VSV21-AA Madule)

This test runs without intervention from the operator. When successfully

completed, it provides a high level of confidence that the VSV21 can
operate as a limited function VT-100, and can sufficiently control and
‘respond to the Q-bus interface, so that it can understand and begin to run.
additional host-based diagnostic software. Until the Q-bus/host interface
is proved, test results are indicated by on-board LED lights.

The VSV21-AA (M7656) module has a green LED and a red LED to
indicate the results of self-test. When the module is powered up both
LEDs are ON. The self-test program first checks:

. The basic operanon of the 68000 mxcroprocessor

. The mterfacmg to the device status register |
If either of these tests fails, both LEDs stay ON. If the tests are successful,
the green LED goes OFF and the foilowmg checks are made:

'+ PROM checksum test

VNVRAM (non-volanle RAM) test

RAM read and write test (by memory bank)

. _68‘000'microprocéssor insfruction set

Serial-line communications (UARTs) with mtemal loopback

Interface to the graphxcs processor

Setting up the graphics processor from configuration switches

Pixel memory read and write (by memory bank)

DIAGNOSTICS

Screen self-test

The last test (screen self-test) is intended for mmal ad;ustment of the color
monitor, and also as a test pass indicator.

If all these tests are successful, the green LED Comes ON and the red LED

goes OFF. Otherwise the previous condition stays. LED timings and the
displayed picture are describedin more detail in Section 4.1.
-

At this point you have the option to select the type of LK201 used on the

VSV21, by entering a specific code via the keyboard. Refer to the VSV21
Installation Manual for detailed procedure.

You can run each of these tests separately by using the host- based

diagnostics. When this is done, the LEDs do not reflect the resuit of
the tests.

3.3.2

Host- Based Duagnostxcs
These host-based routines perform more intensive tests of mdmdual
hardware and on-board software areas, and interfaces of the VSVZI All
results are indicated via the VSV21/host interface.

In order to run the host-based diagnostics successfully, you must conflgure
the VSV21 as a non-console device, and have a separate console terminal
~on the system. You cannot test the VSV21 and, at the same time, use it
as a console terminal for providing error messages and other diagnostic
information.

The host-based diagnostics are designed to run under the XXDP
+ monitor
for PDP-11 systems (ZVSWB?), or under the VAX-MDM for MicroVAX

systems. The diagnostics are distributed in a package which is available
on various media. The medium must be compatible with the system.
In addition, an exerciser module (CXVSVA) is available to run under
DECX/H

Test Indications

Make sure that a color monitor is connected to the VSV21 module, as
described in Section 2.2.3, step 11. Make sure also that the system power
" is switched OFF. Observe the M7656 LEDs and switch the system power
ON. Both green and red LEDs should come on. After about one second
the green LED will go OFF and the red LED will stay ON. This indicates
that the M7656 module has passed the first stage of testing.
After another four seconds, the green LED will come ON again, and
the red LED will go OFF. This indicates that the module has passed
the second stage of testing (see Figure 4-1). Examine the monitor
in Figure 4-2 overleat. If the
display. It must show a picture like that
~ picture is unstable, if the circle is distorted, or if the white border is not
centered, then you need to adjust the monitor controls as described in the
manufacturer’s documentation.

If the displayed picture is incorrect, check the video 3-color cable and all
the associated connections, and check the monitor as described in Section
4.1.2. If the picture is still incorrect, or if the LEDs indicate that a failure
must replace the M7656 module.

Note

You cannot run host-based diagnostics on the VSV21 when it is

configured as the system console. You should connect another
terminal to the host system to act as system console instead.

The standard VSV21 diagnostic reports any loss of data connectron

between the host module and its peripherals with a “TIMEOUT"’
error message. If while running data input tests (Tests 19, 20 and 21)
the diagnostic receives no data within 15 seconds of the test being
commanded, the diagnostic issues the “TIMEOUT" error message and
halts.

When the peripheral concentrator is part of the system configuration, the
peripherals are remote from the host processor and the console device
