Control of our RS-232 / RS-485 modules
There are two options available for controlling our RS-232 / RS-485 modules:
1. Register-based via an open protocol
2. Via plain text input via a terminal program
Please note!
We only recommend using the RS-485 interface in conjunction with a microcontroller and your own serial protocol.
1. Control via our open serial protocol
Serial control is register-based. An open communication protocol was created for this purpose, which is used to address the module’s registers and thus execute read or write commands. The “Protocols & Register Assignment” manual describes the transmission and reception frames for communicating with RS-232/RS-485 modules.
2. Control via plain text using HyperTerminal
The digital inputs and outputs can be controlled or read directly via “plain text” using HyperTerminal. Examples of this can be seen in the adjacent illustration.
