LOAD PROGRAM FROM

ASCII

FILE

Command 2 sets

up

the

CR10

to

load a program

which

is input as

serialASC|l

data

in

the

same

form

as

sent in

response to

command

1.

A download

file

need

not

follow exactly

the

same format

that

is used when listing a program

(i.e., some of.the

characters

sent

in

the

listing

are not really used when

a

program is loaded).

Some rules

which

must

be

followed

are:

1.

"M" must be the

first

character other than a

carriage

return, line feed,

semicolon,

or 7D

Hex.

The

"M" serves

the

same

function

as

"*" does from

the keyboard. The order

in

which

the

Modes are sent

in

does

not

matter (i.e.,

the

information

for

Mode

3

could be sent before that

for Mode

1).

2.

"S" is necessary prior to

the Scan

Rate

(execution interval).

3.

The

colons (:) are

used

to

mark

the

start

of

actual data.

4.

A

semicolon

(;)tells

the

CR10

to

ignore

the

rest

of

the

line and

can

be used after

an

entry so that

a

comment can

be added.

There

are

4

two-character

control codes which

may

be

used to verify that the

CR10

receives a

file correctly:

^B

^B

(2hex,

2hex)-Discard

current buffer

and

reset signature

^C

^C

(3hex, 3hex)--Send signature

for

current

buffer

^D

^D

(4hex, 4hex)--Load current buffer and

reset signature

Ê

Ê

(Shex, Shex)--Load current

butfer,

Exit

and compile program

As

a

download

file

is received,

the

CR10

buffers

the data

in

memory;the data

is not

loaded into the editor or

compiled

until

the

CR10 receives a command

to

do

so.

The

maximum size

of

the

buffer

is

1.5K.

The

minimum file that

could

be sent

is

the

program

listing, then

nE

Ê.

^C ^C

tells

the

CR10

to

send the

signature

(Appendix C.3) for

the

current buffer of

data,

lf

.this

signature does

not

match that calculated

by

the

sending device,

^B

nB

can

be sent

to

discard the

current

buffer

and reset the

signature.

lf

the signature

is

correct,

^D ^D

can

be sent to

tellthe

CRl0

to

load

the

buffer into

the

editor and reset the

signature.

Once

the

complete

file

has been

sent and verified, send

Ê Ê

to compile the

program and exit

the

load command.

PROGRAM

TRANSFER

WITH

STORAGE

MODULE

The Storage Module and Keyboard/Display or

Modem/Terminal

must

both be connected to

the

CR10.

After

keying

*D,

the command

7N,

is

entered

(N

is

the

Storage Module

address

1-8,

Section

3.3).

Address

1

will work with any

Storage Module

address.

The

CR10 will search

for

the

lowest address Storage Module

that

is

connected.

The command

to save,

load,

or

clear

a program and

the program

number

(Table

1.8-2)

is

entered.

After

the operation

is

finished

"13:0000"

is

displayed.

Error 96

indicates that

the

Storage Module is not

connected or the wrong address

was

given.

The datalogger

can

be programmed

on

power-

up using

a

Storage

Module.

Storage Modules

can store

up

to

eight separate

programs.

lf

a

program

is

stored

as program

number 8, and

if

the

Storage Module

is

connected to

the

datalogger l/O

at power-up,

program

number

8

is

down

loaded to the datalogger.
