CR10 OVERVIEW

OV-10

OV3.3.2 ESTABLISHING COMMUNICATION

WITH THE CR10

Communication software is available for most

computers having a serial port. Campbell

Scientific's PC208 Datalogger Support Software

is available for IBM PC/XT/AT/PS-2's and

compatibles. The software must be capable of

the following communication protocol:

1. Configuring an asynchronous serial port for

8 Data Bits, 1 Stop Bit, no Parity, and Full

Duplex at baud rates of 300, 1200, or 9600

baud.

2. Transmitting characters typed on the

keyboard out through the serial port.

3. Displaying characters/data received through

the computer's serial port.

Once the computer is functioning as a terminal,

initiate communications by sending the CR10

several carriage returns for the CR10 to match

the baud rate and respond with "*". Enter the

7H command to enter the Remote Keyboard

State. At this point, the CR10 can be controlled

using the Keyboard Commands described in

Section OV4. For additional information on

communications, see Section 6.7.

OV4. PROGRAMMING THE CR10

A program is created by entering it directly into

the datalogger or on a computer using the

PC208 Datalogger Support Software program

EDLOG. This manual describes direct

interaction with the CR10. Work through the

direct programming examples in this overview

before using EDLOG and you will have the

basics of CR10 operation as well as an

appreciation for the help provided by the

software. Section OV4.5 describes options for

loading the program into the CR10.

OV4.1 FUNCTIONAL MODES

CR10/User interaction is broken into different

functional MODES (e.g., programming the

measurements and output, setting time,

manually initiating a block data transfer to

Storage Module, etc.). The modes are referred

to as Star (*) Modes since they are accessed by

first keying *, then the mode number or letter.

Table OV4.1-1 lists the CR10 Modes.

TABLE OV4.1-1. * Mode Summary

Key Mode

*0 LOG data and indicate active Tables

*1 Program Table 1

*2 Program Table 2

*3 Program Table 3, subroutines only

*5 Display/set real time clock

*6 Display/alter Input Storage data,

toggle flags or control ports.

*7 Display Final Storage data

*8 Final Storage data transfer to peripheral

*9 Storage Module commands

*A Memory allocation/reset

*B Signature/status

*C Security

*D Save/load Program

OV4.2 KEY DEFINITION

Keys and key sequences have specific

functions when using the CR10KD keyboard or

a computer/terminal in the remote keyboard

state (Section 5). Table OV4-2 lists these

functions. In some cases, the exact action of a

key depends on the mode the CR10 is in and is

described with the mode in the manual.

TABLE OV4.2-1. Key Description/Editing

Functions

Key Action

0-9 Key numeric entries into display

* Enter Mode (followed by Mode

Number)

A Enter/Advance

B Back up

C Change the sign of a number or index

an input location to loop counter

D Enter the decimal point

# Clear the rightmost digit keyed into

the display

#A Advance to next instruction in

program table (*1, *2, *3) or to next

Output Array in Final Storage (*7)

#B Back up to previous instruction in

program table or to previous Output

Array in Final Storage

#D Delete entire instruction

#0 (then A or CR) Back up to the start of

the current array.

When using a computer/terminal to communicate

with the CR10 (Telecommunications) there are

some keys available in addition to those found on

the CR10KD. Table OV4.2-2 lists these keys.
