Communication commands:
Command
R/W
Description
Example
v
Read
Query the firmware version number.
Send:v<CR>
Rcv:1.02b<CR>
?
Read
Display a summary of all settings
h
Read
Query the input mode:
0=Analog
1=Q-Link
2=Frequency
Send:h<CR>
Rcv:2<CR>
H
Write
Set the input mode
Send:H0<CR>
r
Read
Query the raw loadpin reading. The lifted load
may be computed from this value as (Raw-
Zero)/Cal. See the ”C” command.
Send:r<CR>
Rcv: 354<CR>
i
Read
Query the device ID.
Send: i<CR>
Rcv: crane34<CR>
I
Write
Set the device ID.
Device ID’s are limited to 18 characters
Send: Icrane45<CR>
z
Read
Query the zero parameter
The zero value is used to calculate the actual
load. See the “C”, and “r” commands/
Send: z<CR>
Rcv: 34<CR>
Z
Write
Set the zero parameter.
Send: Z23<CR>
c
Read
Query the cal parameter.
The cal parameter is used to calculate the actual
load. See the “C” and “r” commands
Send: c<CR>
Rcv: 11<CR>
C
Write
Set the cal parameter.
In normal operation, the cal parameter would be
set as follows:
Send the “r” command to get the raw
reading from the load pin in it’s
unloaded state.
Send the “Z” command to set the zero
parameter
Apply a known load to the pin.
Send the “r” command to get the raw
reading from the load pin.
Sent the “C” command to set the
calibration value to (Rawunloaded-
zero)*Known_Load (in 100Kg units)
Send: C9<CR>
on
Read
Query the overload (setpoint) parameter.
This parameter is stored in 100Kg units, eg 3.5mt
is expressed as 35.
It is used by the device to determine when an
overload occurs.
Send: o1<CR>
Rcv: 35<CR>
On
Write
Set the overload parameter.
Send: O140<CR>
wn
Read
Query the inverted status of a setpoint output. A
return value of 1 means the output is normally
open.
Send: w2<CR>
Rcv: 1<CR>
Wn
Write
Set the inverted status of a setpoint output.
Send: W20<CR>
*
Write
Reboot the device.
This command is usually only used to load new
firmware onto the device
Send: *<CR>
