FAQ:

1.What communication standards does it support?
This module supports:
RS-232 (DB-9 connector)
RS-485/422 (terminal block)
It allows data exchange between controllers and devices using these common industrial serial interfaces.
2.What are typical baud rate and configuration options?
Baud rate: 300 bps to 115200 bps (configurable) 
Configurable data format: data bits, parity, and stop bits are set via system configuration tools.
This makes the module flexible for different device communication needs.
3.How is it powered and mounted?
Input voltage: Typically 24 VDC supplied via the controller backplane or module bus
Mounting: Designed for DIN-rail or control cabinet mounting depending on system requirements.
