RS-232 Operation
You can operate the ED-2000plus with a computer or other data logging
device via RS-232. To place the ED-2000plus in RS-232 mode, use one hand
to press and hold the F key and use the other hand to press the ON key.
This operation is transparent to the user. It is important that the ED-2000plus
and the external device are set at a baud rate of 2400 for RS-232 communica-
tion.
When you press the DATA SEND key in RS-232 mode, or send an enquire
code from the external device to the ED-2000plus, the following information is
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 is a single question mark (?). When the ED-2000plus
receives this code from the external device, the above information is sent.
If your RS-232 port is receiving garbled data, check to be sure you are in
RS-232 mode or that an HR-2000 is not trying to communicate with the
ED-2000plus by radio.
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.
