Specifications
◆RS232C long distance optical converter
- RS232C optical converters are used in pairs.
- RS232C can be extended up to 120 km by optical conversion (single core).
- It communicates bidirectionally between start-stop synchronous devices and synchronous devices via optical fiber.
- No settings are required for communication.
◆Connection configuration
By using optical conversion, the communication distance between two RS232C asynchronous devices can be extended by 120 km.
