APPLICATION DESIGN

67

When

in

the

XP9 mode, it is possible to

cause

the

AX

to

pause

between sequence execution. This is done with

the

XQl

command.

When

the

XQl

command

is

present

within

a

sequence,

the

AX

will

pause

after

the

execution of

the

sequence

and

will

wait for all

sequence

select

inputs

to be OFF (see

sequence #8

in

Table 4-2). The

AX

will

then

read

the

status

of

the

sequence

select

inputs

and

execute

the

corresponding

sequence

number.

This

interrupted

run

mode will

continue

until

you issue

the

XQ0

command.

You

can

also

program

the

AX

to

read

the

sequence select lines

on

power-up

with

the

XPS

command.

This

command

will

cause

the

AX

to

execute

the

first vaUd sequence

number

it

reads

on

the

sequence

select

inputs

after power-up (exactly

Uke

the

XP9

command).

It

differs from

the

XP9

command

in

that

it

returns

control to

the

RS-232C

communications

port

after

it

finishes executing

the

first

sequence,

rather

than

reading

the

sequence

select lines

again

and

executing

another

sequence.

The following

are

step-by-step

procedures

demonstrating

how

to

run

sequences. Using a

tenninal

or

a computer, key

in

the

following

commands:

Issue

the

XP9

corrunand.

Define

the

following

sequences:

Verify

that

your

programs

were

stored

properly

by

uploading

each

entered

sequence

(XU

followed

by

the

number

of

the

sequence).

If

you

receive

responses

that

differ from

what

you

programmed,

re-enter

those

sequences.

Make

sure

all

the

sequence

select

inputs

are

ofT

(not grounded).
