8.3 RS-232C Communication Functions

Function for transmitting and receiving data between external equipment and the RS-232C interface.

8.3.1 Communication Setup Function

Sets up RS-232C communication. Parameters you can set are as follows.
Item*
Baud rate
Data Length
Parity
Stop Bit
* Select the settings in WDS-WIN01.

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*
・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.
