8.3.2 Receive Data Function
・
Following the data file format settings, this product receives data via RS-232C communication. You can select
supported file formats from 3 types*
1
.
・
Maximum receive data size is 60 bytes. Only the first 60 bytes are received when the data size exceeds 60 bytes.
When the receive data size is greater than 30 bytes, the data is divided into 2 and transmitted to the host.
●Receive Data File Format
Direct Communication Format*
2
Data received from RS-232C devices is transmitted directly to WDR.
Bar Code Reader (Denso Wave)
Communication Format*
3

SM(R)].
With this format, the header code, terminator code, and BCC are deleted from
the received data and transmitted to WDR.
Bar Code Reader (generic)
Communication Format*
3
