Passive RS-232 to RS-485 Converter
This passive adapter links an RS-232 port to an RS-485 bus without external power. It suits engineers and hobbyists connecting legacy serial gear or single-chip computers to differential networks.
Upgrade from direct RS-232 wiring
The converter replaces point-to-point RS-232 cables when longer runs or multi-drop topology are needed. The jump is worth it when signal distance or node count exceeds RS-232 limits and a powered isolator is not required.
Highlights
- Converts RS-232 signals to RS-485 format
- Passive design requires no external power source

Questions about this item
Does the RS-232 to RS-485 converter need an external power supply to operate?
No, this is a passive two-way converter that draws power from the serial port signals themselves, so no separate power adapter is required.
How do I connect the RS-232 side to my computer if it only has USB ports?
Use a USB-to-RS-232 adapter cable; plug its DB-9 male end into the converter's RS-232 port, then install the adapter's driver so the OS sees a virtual COM port.
