Communication command
The communication command sends and receives data with the connected host device via the WB1F communication
interface. The arrangement for sending and receiving data is called the "communication commands".
For communication command settings and details, refer to
munication command
There are two types of communication commands: control commands and configuration commands.
Control commands
„
These commands are for directly operating the WB1F. Operations can be performed such as barcode reading and turning
the indicator LEDs on and off.
Configuration commands
„
These commands change and acquire the setting values that define the manner in which the WB1F operates. The settings
for RS-232 communication and the illumination pattern and time for the indicator LEDs can be changed and acquired.
Communication data format, prefix, suffix
The communication data format for communication commands is text (ASCII). (Excluding the prefix and suffix)
z
The prefix and suffix can be changed according to the usage environment.
z
This section uses the factory default state as an example.

Notes on communication
If unwanted data may be stored in the receive buffer because noise is present or the WB1F has not been
z
used for a long period of time while the unit is on, input "prefix+suffix". This will clear the receive buffer.
The send buffer and the receive buffer are 512 bytes. If the buffers store more than that amount of data, data
z
may not be correctly sent or received. Please keep this point in mind when using the WB1F in situations
where RS-232 hardware flow control is enabled.
