DATALOGGER J

AND

K

COMMANDS

3142J

The 8142J command

is used to toggle

dataloggBr user

flags,

request

Final Storage

data,

anfl to establish

the

input locations

returned by the K command.

The

format of

the

comdnand

is as follows:

311 42J<CR>abcd...nNU

LL

where

1)

"3142J<pR>"

is the command.

2)

"a" is a

1

byte

value representing

the

user

flags

to

[e

toggled.

The

most significant

bit

(MSB),

if

set,

will toggle

datalogger

user

flag

8. Likev'1ise, the

2nd

most significant

bit,

if

set,

will

loggle

user

flag

7, and so

on to the

least sigl'rificant

bit

which,

if

set,

toggles

user

flag 1. Toggle

means

that

if

a

flag is

set,

it will

be

then

reset, or

if it is

reset,

it will

be set.

3)

"b"

is a

1

byte

value

whose

MSB

will

determirie

whether

Final

Storage

Data

is

returned

after

the

K command.

lf the bit

is

set,

Findl

Storage

Data, if any,

will be

returned after

the

next K command.

The

datalogger

initially

has this

bit reset upon

entering

telecommunications,

but once

set

by

a J

command,

it will

remain set

until

reset

by

another

J command

or

is terminated.

MSB set

means

a

port

toggle

bYte

and

port

status

is to be

returned

the K command.

Like

the

MSB, this

bit

but

remains set

once set

until

reset by

another

J command

or telecommunications

is

terminated.

The

remaining

bits are

reserved.

lf the

2nd MSB

in

"b"

was

set

then

"c"

is a

port

toggle byte,

otherwise

"c,d,...,n"

are

each

1 byte binary

values

each

representing a

datalogger Input Storage

location.

The data at those locations

will be

returned

after the

next

K

command.

ASCII

code

1

(0000001

binary)

represents input

location

1. ASC|lcodes

2

(00000010

binary)

represents

input

location

2,

and so

on. The order

of the

location requests

is not

important.

The

list is limited, however,

to 62

total

location

requests.

"Null"

or

ASCII code 0

(00000000

binary

)

terminates

the J command.

Alternately,

11111111

binary aborts the J

command.

lf

aborted,

flags

will not be

toggled

and

location

requests

will not

be

saved.

User

Enters

Datalogger

Echo

The

K command

returns

datalogger

time,

user

flag status,

port

status

if requested,

the

data at

the input

locations requested

in the

J command,

and

Final

Storage

Data

if

requested

by

the J command.

The

format

of

the command

is K<CR>

(K

Return).

The

datalogger

will echo the K and

Return

and

send

a Line

Feed.

The

amount

of data

that

follows

depends

on

the

J command
