Other Operational Serial Commands
The following serial utility commands can be entered from Terminal or a PLC.
5-7-26 Train and Optimize
Train Symbol
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.
Un-Train Symbol
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.
After you send the <UNTRAIN> command, you must trigger the reader once more for the untrained
state to take effect.
Train Status
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
Train Persistence
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.
