Radio Operation with

RS-232

The force value received is right

justified with any leading zeroes

replaced by spaces. Negative

values will show a minus sign

before the first digit. The

decimal point will not be printed

if it follows the significant

digits.

WARNING!

HR-2000 is intended to send

only force/weight readings.

Although the HR-2000 can

remotely configure an

ED-2000plus, unpredictable

output may result if Print or

Enquire actions occur while the

ED-2000plus is in configuration

mode.

You can connect the HR-2000 with a computer or other data logging device

via RS-232. There are two communication modes for the HR-2000; normal

operation mode and listen mode. It is important that the ED-2000plus, the

HR-2000 and the external device all be set at a baud rate of 2400 for RS-232

communication.

In normal operating mode, the ED-2000plus and HR-2000 are in constant

contact and the HR-2000 screen reflects what the ED-2000plus screen

shows. Information can be sent to an external device by pressing the DATA

SEND key on the HR-2000.

In listen mode, the HR-2000 waits to receive an enquire code from the exter-

nal device, polls the ED-2000plus for the information, then returns it to the

external device.

To enter listen mode, use one hand to press and hold the F key and use the

other hand to press the ALT key. In listen mode the display shows the word

LISTEN and keys are nonfunctional.

Following is the format of the information sent to the external device:

xxxxx.x uu CR/LF

x = force value

u = unit of measure (LB, KG, KN or T)

CR/LF = carriage return and line feed

The enquire code for the HR-2000 is a question mark plus a carriage return

(?,CR or ASCII Codes 63,13). When the HR-2000 receives this code from the

external device, the above information is sent.

The action of sending information or polling for information can introduce

delays in communication between the HR-2000 and ED-2000plus.

If your HR-2000 does not automatically detect the RS-232 connection, turn off

the unit, then power up by using one hand to press and hold the ALT key

and using the other hand to press the ON key. This forces the unit into RS-

232 operation.

(if in LISTEN mode, a less than symbol (>), ASCII

code 62, is also sent after the line feed)
