External computer control via an RS232C terminal

External computer control via an RS232C terminal

If you connect the optional "RS232C Communication Kit," the Ergo- ciser™ can communicate with an external computer.

Specifically, you can write a program with an external computer in Basic or in another computer language, and operate the Ergociser™ EC-3700 according to the written procedure. Any instructions input by the buttons on the EC-3700 control unit can be input from the ex- ternal computer, and the EC-3700 sends data to an external computer every second. Since command signals are in ASCII character code, any computer that generates these codes can be used, receiving and transmitting via the RS232C terminal.

Contents of Data Transmission from the EC-3700

The EC-3700 outputs display data in character code, continuously when you set exercise conditions and once per second when you are exercising. Since the contents of the LCD differs according to setting exercise conditions and during exercise, the content of data output also differs.

1) Setting Exercise Conditions

Address	Data	Function
1	A code	Hexadecimal 41H
2	3 digit numeric	Set wattage (Isopower Training)
5	1 digit numeric	Exercise pattern (Interval Training)
6	3 digit numeric	Target pulse rate (Auto Training)
9	1 digit numeric	Sex (male:"1", female:"0")
10	1 digit numeric	Exercise pattern (Hill Profile Training)
11	2 digit numeric	Set torque x 10
13	3 digit numeric	Weight (Aerobic Power Measurement)
16	2 digit numeric	Target time (minutes)
18	3 digit numeric	Pulse limit value
21	2 digit numeric	Age
23	CR code	Hexadecimal 0DH
2) During Exercise
Address	Data	Function
1	B code	Hexadecimal 42H
2	4 digit numeric	Elapsed time	2 digits = "minute"
			2 digits = "second"
6	4 digit numeric	Calorie consumption
10	3 digit numeric	Wattage
13	2 digit numeric	Pedal torque x 10

15	3 digit numeric	Pulse rate
18	3 digit numeric	Pedal cadence
21	1 digit numeric	Aerobic power measurement result: PFL
22	2 digit numeric	Aerobic power measurement result: MOU
24	3 digit numeric	Aerobic power measurement result: PWC max.
27	3 digit numeric	Set wattage (Isopower training)
30	2 digit numeric	Lowest 2 digits of addition value of data address 2 ~ 29
32	CR code	Hexadecimal 0DH

Note: "0" is displayed in each digit for the 3 types of aerobic power measurement results, until the program is completed.

Externally Controlling the EC-3700

1) During Setting Exercise Conditions

When exercise conditions are being set, you can send data in a "char- acter code + numeric code + CR code" format (shown in example below) from an external computer, setting your exercise conditions.

Example)	"K6CR" : Selects Auto Training
Character Code	Function
A	Age (up to 2 digits)

BPulse limit value (up to 3 digits)

CTarget time (up to 2 digits)

D Weight (up to 3 digits)

ESet torque x 10 (2 digits)

FExercise pattern (Hill Profile Training)

GSex (male: "1", female: "0")

HTarget pulse rate (up to 3 digits)

ISet wattage (up to 3 digits)

JExercise pattern (Interval Training)

KExercise program

1:Aerobic Power Measurement

2:Manual Training

3:Hill Profile Training

4:Interval Training

5:Isopower Training

6:Auto Training

LReset torque during exercise x 10 (2 digits)

2)During Exercise

By using the following character codes for button operation, you can externally control the program during exercise.

Example) Sending "i CR" during Manual Training

–>increases pedal resistance (torque) 0.1 kg•m

Character Code	Function
r	RESET button
g	ADV button
i	+ 1 button
d	– 1 button

See the instruction manual for the optional "RS232C Communication

Kit" for details.
