Protocols Serial (RS-232 / RS-485)
Does Nodlyn support Serial (RS-232 / RS-485)?
Talk to meters, sensors, and legacy gear on COM / tty ports.
Compatibility answer
Yes — at the protocol level. Nodlyn can discover Serial (RS-232 / RS-485) endpoints and register them for visual workflows.
Discovery can list serial ports (filter by COM / ttyUSB / ttyACM).
What Serial (RS-232 / RS-485) support means in Nodlyn
RS-232 / RS-485 still connects meters, lab instruments, and Modbus RTU adapters. Discovery lists COM / ttyUSB / ttyACM ports; you set baud and frame parsing, then forward values to MQTT, HTTP, or a database.
For pure Modbus TCP on Ethernet, prefer the Modbus page. Serial is the compatibility path when the wire is a COM port.
This page is a compatibility check (supported or not, how you connect). Step-by-step tutorials live on the blog when linked below — so Google (and readers) get one clear “how-to” URL.
Example automations with Serial (RS-232 / RS-485)
- Meter frame → parse → log
- RS-485 adapter → Modbus-like fields
- COM instrument → MQTT forward
Quick start for Serial (RS-232 / RS-485)
- Open Discovery → Advanced → Serial, or add Serial nodes.
- Pick the port and baud settings from your device manual.
- Parse frames into fields.
- Log, alert, or forward over MQTT/HTTP.
