Serial Interface 1 SI RS232/RS422/RS485

The serial communications module from the TB20 product line can be used for serial data transfer as defined in the RS232/RS422/RS485 standard between two communication devices using low to medium transmission rates. 

The other communication device can be a serial module or any other device that supports the aforementioned standard. 
This serial module supports both the ASCII and 3964R protocols. This makes it possible to integrate downstream devices (e.g., printers, laser scanners, etc.) into higher-level bus systems and networks in an automation system, or to communicate with other system parts.
