M-9 Other Operational Serial Commands
The following serial utility commands can be entered from
Terminal
or a PLC:
Format:
<TRAIN>
: Initiates a Train operation.
This command will put the product into a mode of operation that will cause it to “train” the next symbol
decoded. This mode of operation will remain active until either a symbol is decoded or the call is made to
disable the mode and revert back to normal operation. Upon decoding a symbol, the image processing will
save pertinent information regarding the target symbol to allow higher readability for the similar symbols.
The data collected by the Train operation can be saved for a power-on condition, using the
<Z>
command.
Format:
<UNTRAIN>
: Initiates an Un-Train operation.
This command will cause the product to discard any information acquired during a Train operation. The
Untrained state can be saved for a power-on condition, using the
<Z>
command.
Format:
<TRAIN?>
: Responds with Train Status
This command will return the current status of the TRAIN operation.
Response:
< TRAIN,0>
: Default, not trained
<TRAIN,1>
: Train operation in process
<TRAIN,2>
: Symbol trained
The train state and parameters persist the same as ordinary parameters. Examples:
•
A unit in the trained state has not been saved. A power cycle will remove any trained state information
and the unit will come up in its configured state.
•
A unit is saved in a training state. The unit will come from power up in the training state and train the
first symbol read.
•
A unit is saved in a trained state. The unit will come from power up in the trained state and only read
the trained symbol type.
•
A trained unit is issued a reset default command
<Ard>
. The unit will return to an untrained state but
if power is cycled will return to its saved state.
Format:
<OPT>
Initiates an Optimize operation.
This command will put the product into a mode of operation that will cause it to “optimize” the next
symbol decoded. This mode of operation will remain active until either a symbol is decoded or the call
is made to disable the mode and revert back to normal operation. Upon decoding a symbol, the image
processing will save pertinent information regarding the target symbol to allow it to be processed
quicker and more consistently.
The data collected by the Optimize operation can be saved for a power-on condition, using the
<Z>
command.
