Inquiry Cycle
1. Upon a successful Power up Sequence, the scale will transmit an ENQ 05hex
out of the RS232 port.
2. The scale will then wait five (5) seconds for a response.
3. If a response is returned, it will be acted upon per the Response Table below.
Response Table
Possible replies
Scale action taken
0dhex = carriage
return
If the transmission mode is TP, transmit the current weight on the scale in
the current units. There will be no ACK transmitted for this command but if
the mode is not TP, a NAK will be transmitted.
Weight string transmitted will be 11 characters
P = Polarity
WWWWW = weight string including decimal and leading spaces
UU = units, either lb or kg
S = stable weight reading, S for stable, U for unstable or motion
on scale
This string may also be
an error condition.
“CAL”
Enter calibration mode.
“DEF”
Load default settings.
Units = lbs, Filter factor = 2 = medium, Transmission mode = TW, output
rate is slow or 500ms and the timer is reset.This takes the scale out of a
customized state.
“F#”*
Change to filter #, either 1, 2, or 3 where 1 = light, 2 = medium, 3 = heavy.
Default will be 2 = medium.
‘M’
Transmit the current mode including units, filter setting and transmission
mode. Example “ULF3TW”
“Or”*
Output rate for TC/continuous mode. ‘r’ is to be ‘F’ for fast or ‘S’ for slow.
Fast = 200ms, slow = 500ms between outputs.
“TW”, “TP” or “TC”*
Change to transmission mode indicated. TP and TC mode do not allow the
scale to power down.
-TW = Use the Stable Weighment Cycle (default or Stand Alone Weighing
mode)
-TP = Use a polled interface similar to the Ultegra using a Carriage Return.
-TC = Continuously transmit the weight on the scale per the output rate
setting.
“UL” or “UK”*
Change to units in response.
Default will be lb.
‘Z’
Zero the scale.
