Utilities
Other Operational Serial Commands
The following serial utility commands can be entered from Terminal or a PLC:
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.
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.
