Detailed descriptions

of

the

instructions are

given in Sections

Entering

is

described

in

ENTERING

A

PROGRAM

Programs are

entered

into

the

CR10 in one of

three ways:

1.

Keyed in using the CR10 keyboard.

2.

Loaded

from

a pre-recorded listing using

the

*D

Mode.

There are

3

types of

storage/input:

a.

Stored on

disl</sent

from

computer

(PC208 software GraphTerm and

EDLOG).

b.

Stored/loaded

f

rom

SM192n

16

Storage

Module.

3.

Loaded

from

internal PROM (special soft-

ware) or Storage Module upon power-up.

A program

is

created

by keying

it

directly into

the datalogger as described in Section OV5,

or

on

a

PC using

the

PC208 Datalogger Support

Software.

EDLOG and GraphTerm

are

PC208 Software

programs

used to develop and

send

programs

to

Campbell Scientific

dataloggers.

EDLOG

is

an

editor for writing and documenting programs

for

Campbell Scientific

dataloggers.

Program files

developed

with

EDLOG

can

be

downloaded directly

to

the

CR10 using

GraphTerm.

GraphTerm

supports communication via direct wire, telephone,

or

Radio Frequency

(RF).

Programs on disk

can

be

copied

to

a

Storage

Module with

SMCOM.

Using

the

*D

Mode to

save

or

load

a

program

from

a Storage Module

is

described in

Section

1.8.

It is possible (with

specialsoftware)

to create

a

PROM (Programmable Read Only Memory)

that

contains

a

datalogger program.

With this

PROM installed

in

the

datalogger,

the

program

willautomatically

be loaded and

run

when

the

datalogger

is

powered-up, requiring only

that

the

clock

be set.

The

program

on

power

up

function

can

be

achieved by using a

SMl92716

Storage

ov-l2

Module.

Up

to

8

programs can be

stored

in

the

Storage Module,

the

programs may be assi

any

of

the

numbers

1-8.

lf

the

Storage Module

is

connected when

the

CR10 is powered-up the

CR10 will automatically load program number

provided that a program 8 is loaded

in

the

Storage Module (Section

1.8).

PROGRAMMING EXAMPLES

We will start with a

simple

programming

example. There

is

a brief explanation of each

step

to

help you follow

the

logic.

When the

example uses an instruction,

find

it

on

the

Prompt Sheet and follow through the descri

of

the parameters.

Using

the

Prompt Sheet

-yvhile

going through

these

examples

will

help

you

become familiar

with

its

format.

Sections

9

12

have more detailed descriptions

of

the

instructions.

Connect

the

CR10 to either a

CR1OKD

Keyboard/Display or

a

terminal

(Section OV2).

With the

Wiring Panelconnected

to

the

CR10,

hook

up

the

power leads as described

in

Section

OV1.2.

lf using

a

terminal,

use

the

7H

command

to

get into

the

Remote Keyboard

State

(Sections

5.2).

The

programming steps

the following

examples

use

the

keystrokes

possible

on

the keyboard/display.

With

a

terminal,

some

responses

will

be slightly

different.

lf

the

CR1OKD is

connected to the CR10 when

it

is

powered

up,

the display

willshow:

Displav

HELLO

after a few seconds

delay

Explanation

On power-up, the CR10

displays "HELLO"

while

it

checks

the

memory (this

display occurs only with the

cRloKD).

The size

of

the

machine's total

memory (RAM plus

32

K

ot

ROM),

in

this case 96K
