Datalink RS485/P Series RS232C⇔RS485 Converter
Manufacturer: DataLink
Model: RS485/P Series
Features
- This is an RS232C⇔RS485 converter that operates without the need for an external power supply, drawing power from the RS232C signal line.
- An optional AC adapter can also be used if needed.
- The RS232C side uses a Dsub9-pin female connector with a DCE arrangement.
- The RS485 side is equipped with a compact 5-pin terminal block (insertion screw type) for easy wiring.
