COMMA

DELINEATED

ASCII

Comma Delineated ASCII strips

all

lDs, leading

zeros, unnecessary decimal points and

trailing

zeros, and plus

signs.

Data points are separated

by

commas. Arrays

are separated by Carriage

Return Line

Feed.

Comma Delineated ASCII

requires approximately 6 bytes per data point.

STORAGE MODULE

(SM192I716)

The Storage Module stores

data

in battery

backed

RAM.

Backup is provided by

an

internal

lithium

battery.

Operating power is supplied by

the CR10 over

pin

1

of

the

9-pin connector.

When power

is

applied to

the

Storage Module,

a

File Mark is placed

in

the

data

(if

a

File Mark

is

not

the

last data point already

in

storage).

The

File Mark separates

data.

For

example,

if

you

retrieve data

from

one CR10, disconnect

the Storage Module and

connect

it

to

a

second

CR10,

a

File Mark

is

automatically placed

in

the

data.

This markfollows

the data from the

first

CR10 but precedes the data

f

rom

the

second.

The SM192

has

192K bytes

of

RAM storage;

SM716 has 716K

bytes.

Both

can

be

as

either

ring or

fill

and

stop

memory.

STORAGE

MODULE ADDRESSING

The capability of assigning different addresses

Storage Modules

allows

1) multiple

(up

to

8)

Modules

to

be

connected to the CR10 during

output

(lnstruction

96), 2) different data

to

be

to ditterent Modules, and 3)

transfer

of data

Module

that

is left with the CR10 to

a
