The VSVZI is a single-module quad size opuon for the.
Q22 Bus. It is a high functionality graphics control
module capable of working on the following processors:

e PDPI1/23+
‘@ PDPI11/53
e PDPI11/73

e PDP11/83

® MicroVAX IT

- It is capable of interfacing with:

o A color monitor

e An LK201 keyboard

. A pointing device (Joystlck trackball, mouse, tablet)
® A serial interface (example DHV] l)

When the VSV21is mterfaced to the host processor via
its serial interface, it can be configured to emulate a basic

terminal. In this configuration the Q22 bus interface is

not used, and the YSV2I can be used as the host console

CONFIGURATIONS
VSV21 is designed to work with 60Hz Non-Interlaced

Monitors of either 16kHz (nominal) or 32 kHz (nominal)
line frequency. The video signals are compatible with
- RS343 specified voltage levels with sync on green and

standard should option be terminated in a 75 ohm

SWITCH SETT]NG

Switch 8 in switchpack E48 is used to dlsable the
module’s responseto BUSINIT signals. If the VSV21 is
used as a system console, it will normally respond to

BUSINIT signals and clear the display when it enters
selftest. This may give rise to problems in running

diagnostics on other modules. Switch 8 can be moved to
disable the response to BUSINIT signals and should be

| returned to ON on compleuon of diagnostic testmg
Swntch 8 is OFF to disable the module s response to
BUSINIT signals and

ON to enable

the

module S

response to BUSINIT

Thejumpers Wl and W2 should be mstalled when the
M7656 module OCCUplCS a Q/Q slot, and should be
removed when it occuples a Q/CD slot.

CONFIGURATIONS

2. 5 SERIAL PORT DEFAULTS
The VSV21 module serial interfaces are configured to
the following default settings. Other settings must be
entered on replacement modules:
|

@ Port 0 KEYBOARD 8-data bits, 1 Stop bit, No
Parity, 4800 Baud

® Portl HOSTPORT 8-data brts | Stop bit, No Parity,
9600 Baud
e Port 2 POINTING DEVICE 8- data bits, 1 Stop bit,
‘No Panty, 9600 Baud
o Port 3 TRANSPARENT SERIAL 8-data bits, | Stop
bit, No Parity, 9600 Baud

Other default settings can be entered and saved on the
module. Check to see if the customer has altered and
saved the default settings. When a moduleis replaced. it
must be correctly altered and the settings saved so that
the moduleis compatible with its peripherals.
2.6 REMOTE BOX INTERNAL POWER SUPPLY
The VSV21 PC remote box has an integral power
supply which has been configured in manufacturing to
accept the local mams supplyie. 110-120/220-240V. See
figure 6.1.
|

ON-BOARDSELF-TEST .

The VSV21 contains an on-board ‘diagnostic held m

ROM, which runs on power-up

To run the tests you must first make sure the power is
turned OFF and you must gain access to the module cage
by removing the covers from the appropriate housing
box.

Locate the M7656 module and the position ofthe two

| for the layout of the
on-board LEDs. See Figure
module. The LEDs will give an md:catnon when the

diagnostics are running.

- Now turn the power ON

The result of the on-board dlagnostlc tests is dlsplayed
on the monitor screen and on the Red and Green LEDs'
in the followmg way:

Figure 3-2 shows the picture that is dlsplayed on the
monitor screen. If you do get the TEST OK indication
but not the correct picture, use the trouble-shooting flow
charts shown in Chapter 6 to identify the problem.

‘The test picture remains on the screen until:

® The host sofltware starts to use the VSVZl by
down-loading to it or

® A keyis pressed on the attached key‘board or

keyboard

Either of the last two wnll cause the option to enter the

terminal emulatnon mode.

If the keyboard version has not been permanently

saved in NVRAM, then it can be selected after the
completion of every power-up self-test. If it has been
~saved, then it can onl'y be changed either by software
control or by running the Parameters Reset test of the
diagnostic suite.

The test pictUre displayed gives an indication if the
keyboard version has been saved or not. If not, it
displays the message NVRAM X on a Red rectangular
background. You can now enter the number associated
with the keyboard version; then press the RETURN key
and the VSV21 will clear the display and enter terminal
emulation mode (see Appendix B for list of LK20l
keyboard versions and the assocxaled numbcr code

If the keyboard version has been previously saved,

then the picture will display the message NVRAM vona
Green rectangular background. The keyboard version
~can only be changed by either program control or by
clearing the NVRAM using the diagnostic programs.
Press the RETURN key and the VSV21 clears the screen

6. (Standard VSV2I Option Only).Check that the
fuses on the M7656 module are not blown by
checking that + 5 volts is available at pin 11, and
+12 volts

25-way D-type

connector on the [/O bulkhead panel. Use pin 1 or
- pin 7 as the common return. Fuse F1 is for the 12
volt supply, and F2 for the 5 volt supply. Replace
- any faulty fuses. The ratmg should be 3.0 amps.
WARNING

Do NOT plug-in or unplug the keyboard or the

pointing device while system power is switched

- ON. The current surge will blow the module
fuses. Always plug-in or unplug, with the power

switched OFF. (This warning does not apply if
the YSV21 PC OptiOn is installed.)

1. (VSV21 PC option only). Check that the +5 volt
LED on the remote interface boxis lit. If the LED
is not lit,momentarily press the +5V RESET
pushbutton on the box. If the LED does not then
light and remain lit, and the pushbutton remain
locked-in, switch OFF the ac mains supply and

NOTE
When the VSV21 is used as the host console

terminal, it is not possible to run the host-based

dingnostics-for"mo'dule testing, and also get back
error messages. Therefore, when used as the
console, only the on-board self-test can be run.

However, it is possible to run the diagnostic on
the VSV21 used as a host console if another
terminal is connected temporarily to the host

port of the system. Diagnostics can be run on ail

INSTALLATION

e Connect any of the penpherals such as the keyboard,

colour monitor, pointing device and printer. For the

standard VSV21 option, this connection is made
direct to the 1/O bulkhead panel. For the VSV21 PC

option, the keyboard, pointing device and printer are

connected to the remote interface box; the colour

- monitor connects direct to the I/O bulkhead panel via

the vndeo cable assembly
WARNING

Do NOT plug-m or unplug the keyboard or the
pointing device while system power is switched

ON. The current surge will blow the module
fuses. Always plug-in or unplug with the power

switched OFF. This WARNING does not apply =

to the VSV21 PC option.

- ®

Power ON and check the on-board dlagnostlc LED

indications, and check the monitor display pncture

® Run appropriate diagnostic programs to verify that

all installed items are operating correctly.

6 - TROUBLESHOOTING
NOTE

The VSV21 uses a non-volatile RAM (NVRAM)

to store various parameters associated with the
configuration of the module. These settings can
be altered by the

customer under

program

control. Be aware that some problems reported
can in fact be due to an incompatibility between

these

settings and the

requirements

the

‘peripherals connected to the VSV21. Refer to
Appendix
D for further information about the
NYRAM.

THE NVRAM — NON-VOLATILE RAM

On Power-up or after a Bus Reset the VSVZI wxll’v

attempt to use the parameters stored in NVRAM

- configure the module. If no data has been saved in
'NVRAM, the VSV21 will default to the settmgs storedin

ROM and on the resolution configuration switches on
‘the module. This conditionis indicated on the Power-Up
Self Test Pictureby a ’NVRAM X’ message on a red

background

.NOTE
~

Runnmg the NVRAM Read/Wnte Test on a L

module that has not yet had any parameters

saved permanently will cause the default settings
to be saved. Running this test will not affect
parameters already saved by the customer

The dnagnostlcs also provrde a Control Parameter

~ Reset Test which will clear the NVRAM so that on the
next Power-up or Bus Reset the hctory defaults will be

used. This test can be used to 'clear’ the VSV2I toa

known state.

The NVRAM has a life of 100()() storage cycles
(minimum). The diagnosticis designed to minimise the

potential of damage to the NVRAM by asking the user
to answer a qustion on every pass of the tests that write to

it. This will stop damage occuring if the tests are started

with no pass limit.
