This

test

verifies

that

the

keypad

matrixes

are

operating

correctly.

To

select

the

Key/Display

test,

press

6

from

the

Diagnostic

menu.

The

2500

displays:

Press

1

and

the

2500

displays:

Press

the

keys

you

want

to

check.

The

characters

for

these

keys

appear

on

the

display,

in

the

first

column

of

the

second

row.

As

you

press

additional

keys,

the

displayed

characters

wrap

to

the

third

to

end

the

test

and

return

to

is

functioning

properly.

CAUTION:

Do

not

turn

off

power

while

this

test

is

in

progress.

Turning

the

Programming

Electronics

Self-test

The

programming

electronics

assembly

goes

through

a

complete

self-test

on

powerup,

or

when

you

select

self-test

from

a

special

menu

in

TaskLink.

The

self-test

command

allows

you

to

test

portions

of

the

programming

electronics

(PE)

to

verify

proper

operation

or

to

isolate

a

problem.

The

2500

verifies

internal

voltages

every

time

it

is

powered

up

and

every

time

a

complete

self-test

is

run.

The

voltage

verification

is

performed

by

software

and

is

compared

to

a

precision,

laser-trimmed

+10

volt

reference.

Data

I/O

recommends

that

you

cycle

and

run

a

complete

self¬

test

cycle

at

least

every

three

months

so

that

the

PE

remains

within

its

specified

operating

range.

To

ensure

that

your

2500

continues

to

meet

product

performance

specifications,

Data

I/O

recommends

a

complete,

preventive

maintenance

check

and

performance

evaluation

every

three

months.

Powerup

Self-test

During

powerup,

the

PE

performs

self-test

diagnostics,

including

a

performance

verification

of

its

internal

power

supplies

and

a

test

of

the

microprocessor's

kernel

components

(EPROM,

ID

PAL,

system

RAM,

DUART,

and

decode

circuits).

When

the

kernel

tests

are

complete,

the

PE

reads

the

system

files

on

the

disk

drive

and

loads

them

into

its

system

RAM.

Then

it

completes

self¬

test

by

checking

its

major

boards

and

assemblies.

The

PE's

completion

of

the

self-test

indicates

only

that

the

main

components

are

functioning

enough

for

the

PE

to

complete

the

self-test;

it

does

not

necessarily

indicate

the

absence

of

errors.

ESD

Precautions

The

circuit

boards

in

the

2500

are

susceptible

to

electrostatic

discharge

(ESD),

which

can

damage

the

circuitry

in

the

programming

electronics.

The

easiest

way

to

prevent

damage

from

ESD

is

to

make

sure

a

common

static

potential

(ground)

exists

between

the

static-sensitive

device,

its

environment,

and

you.

Use

an

antistatic

strap

to

ground

yourself

to

an

antistatic

workstation.

WARNING:

To

avoid

electric

shock,

the

antistatic

wrist

strap

must

contain

a

1

M

(minimum)

to

10

M

(maximum)

isolating

resistor.

If

you

don't

have

an

antistatic

work

station

available,

you

can

wear

an

antistatic

wrist

strap

and

connect

it

to

the

banana

plug

on

the

2500.
